Contains instructions to perform various release steps in the Release Plans.

Initial Backward Compatibility Check

This initial step checks if the previous release cycle, or more recent bugfix releases done since, have properly set the xwiki.compatibility.previous.version property in the top level POM of xwiki-commons (for the branch you are currently releasing).

For example, if the current release to be made is for 4.2-milestone-3 and, in the meanwhile, there have been released bugfix versions for 4.1 (4.1.4 being the latest released), you need to ensure that the value for xwiki.compatibility.previous.version is 4.1.4.

Verify JIRA issue

If there are opened JIRA issues for the version you are currently releasing (fixVersion is set to the current release), you have two options:

  1. The issue has no code committed yet (Commits tab shows nothing). In this case, you need to push the issue to the next development version. (e.g. fixVersion = 6.3-milestone-1 will be moved to fixVersion = 6.3-milestone-2)
  2. There is some code already committed (Commits tab is not empty). In this case, you need to contact the assigned developer of the issue and find out if the committed code is complete:
    1. If the code is complete, you can close the issue (or ask the dev to do it)
    2. If the code is not complete, you can close the issue and ask the dev to create a new issue for the remaining work to be done for the next version.

In all cases, all opened issues must be closed before the release can be done.

Log on Release machine

# Get on the maven CI master machine
[email protected]:~$ ssh [email protected]

# Get on the agent machine
[email protected]:~$ a1-1

Set up your identity

The first time

  • Configure your Github profile to add the SSH key of the agent so that the commits can be pushed to Github with your user (To get the agent SSH key, do cat ~/.ssh/id_rsa.pub). To verify it works, do the following on the agent machine: ssh -T [email protected]. It should reply with Hi <your user id>! You've successfully authenticated, but GitHub does not provide shell access..
  • Create your own GPG key if you don't already have one: gpg --gen-key
  • Publish your public GPG key, if you have not already done so: gpg --keyserver hkp://pool.sks-keyservers.net --send-key <keyID>
  • Import your GPG key:
    • On your local computer run: gpg --list-secret-keys
    • Export your key in a secret.key file: gpg --export-secret-keys «keyID» > secret.key where keyID is the 8 characters long hexadecimal string on the sec line
    • Copy the secret.key file to the agent machine (you may need to copy to maven.xwiki.org first and then to agent-1-1)
      • From your local computer, upload the key to maven.xwiki.org: scp secret.key [email protected]:/home/maven
      • From maven.xwiki.org (/home/maven): scp secret.key a1-1:/home/hudsonagent/<yourname>.gpgkey (give it a name)
        • The key can be stored on the agent, since it's password protected, so that you don't have to upload it next time, and just re-import it.
        • TODO: find out how we can keep the keys imported and tell maven which one to use during the release.
      • Remove the key from maven.xwiki.org after you have uploaded it to agent-1-1: rm secret.key
    • On the agent machine, run gpg --import <yourname>.gpgkey
  • You need to have a .gitconfig.<yourusername> file. You can do that by copying one of the existing gitconfig file
  • Make sure your gitconfig file has the key signingkey in the [user] section (the value is your key id which you can get with gpg --list-secret-keys).
  • Copy your .gitconfig.<yourusername> file as the main gitconfig file: cp .gitconfig.<yourusername> .gitconfig

The other times

  • Configure your Github profile to add the SSH key of the agent so that the commits can be pushed to Github with your user (To get the agent SSH key, do cat ~/.ssh/id_dsa.pub). To verify it works, do the following on the agent machine: ssh -T [email protected]. It should reply with Hi <your user id>! You've successfully authenticated, but GitHub does not provide shell access..
  • Make sure previous release manager did not left his GPG key
    gpg --delete-secret-and-public-keys `gpg --list-secret-keys | grep ^sec | cut -d/ -f2 | cut '-d ' -f1`
  • Import your GPG key, run gpg --import <yourname>.gpgkey
    • If you did not leave your secret key file on the agent machine, you have to re-upload it (see The first time section above).
  • Copy your .gitconfig.<yourusername> file as the main gitconfig file: cp .gitconfig.<yourusername> .gitconfig

Script to automatize this step

  1. Put this script on your local machine. 
  2. Replace the USER_NAME variable. 
  3. Make sure you have exported your secret key in a file called secret.key in your user directory. 
  4. Don't forget to give execution right to the file. 
  5. Execute and enjoy!
#!/bin/bash

USER_NAME='gdelhumeau'

function log {
       ## Colors
       RESET_TEXT_COLORS='\033[0m'
       GREEN_TEXT='\033[1;32m'
       BLACK_BACKGROUND='\033[40m'

       echo -e "${GREEN_TEXT}${BLACK_BACKGROUND}$1${RESET_TEXT_COLORS}"
}

log "Copy secret key to the maven machine"
scp ~/secret.key "[email protected]:/home/maven/${USER_NAME}.key"

log "Put it on the agent1-1"

printf "\033[0;91m\033[0;100m"
ssh [email protected] "ssh a1-1 'cat /home/hudsonagent/.ssh/id_dsa.pub'"

log "Connect to hudsonagent"
ssh -tt [email protected] "ssh -tt a1-1"

Update Release scripts

# Update the release script
[email protected]:~$ cd xwiki-dev-tools ; git pull --rebase ; cd ..
Do a git status to verify that there are not any committed but not pushed stuff lying around...

Configure the Java Version

Depending on which branch you are releasing from you may have to use a different Java version than what is used on master. To change the Java version you need to remove the "java" symbolic link from the home folder and recreate it to point to the "javaX" folder that corresponds to the Java version you have to use.

# See what Java versions are available.
[email protected]:~$ ls -al | grep java
# Change the Java version
[email protected]:~$ rm java
[email protected]:~$ ln -s java7 java
# See if the change has been taken into account.
[email protected]:~$ java -version

Update Translations

When you release a .x version (bug fix release), be very careful when you update translations because the new ones might concern new stuff introduced in the master branch. The issue is that the translations platform does not support branches (translations are coming from master).

For a release candidate, the translations were already merged (when the Pull Requests were accepted) into the master branch which you have just forked.

For a final version, there may be translations added since the RC that we need to integrate. Perform the following steps:

  • Move to xwiki-trunks:
    [email protected]:~$ cd releases/xwiki-trunks/
  • Run the update goal of the script with your branch (e.g. stable-10.5.x):
    [email protected]:~/releases/xwiki-trunks$ ~/xwiki-dev-tools/weblate-scripts/apply_translations.sh update stable-10.5.x
  • Review the changes for anything amiss.
    • You need to go through each project (xwiki-commons, xwiki-rendering, xwiki-platform)
    • Do a git status to spot changes.
      • Do a git diff --cached and visually review modified translation keys and spot problems (like spam). Do not spend too much time here, since major issues should have been reviewed by the committer that merged the Pull Request, a quick scan is enough to spot obvious problems.
      • No need to do a git add at this point since it will be done for all projects below.
  • Push / commit the translation changes on the branch of the version you are releasing (e.g. stable-10.5.x):
    hudsona[email protected]:~/releases/xwiki-trunks$ ~/xwiki-dev-tools/weblate-scripts/apply_translations.sh push stable-10.5.x

Collect the list of updated languages to publish in the Release Notes:

  • cd to each repository (xwiki-commons, xwiki-rendering, xwiki-platform)
  • Run the list_translation_changes.sh script to list all relevant modified translation files since the previously released final version and generate the list of modified languages (notice the usage of the --diff parameter to help you decide if a translation language should be counted or not, see below for more details):
    ## list_translation_changes.sh start_commit end_commit [options]

    ## Example when releasing a final version (e.g. 10.7):
    [email protected]:~/releases/xwiki-trunks/xwiki-commons$ ~/xwiki-dev-tools/weblate-scripts/list_translation_changes.sh xwiki-commons-10.6.1 stable-10.7.x --diff | more
    ## Example when releasing a RC version (e.g. 10.7RC1):
    [email protected]:~/releases/xwiki-trunks/xwiki-commons$ ~/xwiki-dev-tools/weblate-scripts/list_translation_changes.sh xwiki-commons-10.6.1 HEAD --diff | more

    ## Other examples on some already released versions (in case the need arises):
    [email protected]:~/releases/xwiki-trunks/xwiki-rendering$ ~/xwiki-dev-tools/weblate-scripts/list_translation_changes.sh xwiki-rendering-10.3 xwiki-rendering-10.4 --diff | more
    [email protected]:~/releases/xwiki-trunks/xwiki-platform$ ~/xwiki-dev-tools/weblate-scripts/list_translation_changes.sh xwiki-platform-10.3 xwiki-platform-10.4 --diff | more
  • Merge the list of updated language codes across all the repositories (from the output of the commands above) and update the Release Notes in the Translations section with these language codes.
    • Only count what should be counted:

      Be careful to only count real translation changes. For example if Weblate reorder the translations but no new translation is added, the language should not be counted.

      At the moment the script keeps all changes of the type `<start of line>key=value`, i.e. it discard comments for ex `#Missing someKey=someValue` is not counted.

    • Skip duplicates and sort the final list alphabetically.

Build the release

Tip: running the release script will first ask you for your GPG key passphrase. If you mistype or enter a wrong passphrase, the release will fail to perform. You can test your passphrase locally running the following command :

echo "test" | gpg --no-use-agent -o /dev/null --local-user <KEYID> -as - && echo "Passphrase is correct"

If for a reason or another you've made a mistake typing your passphrase in, you will need to delete (locally on the agent machine) the release branch and created tag before you can start over again.

For Milestone, RC and Final releases

When releasing a Release Candidate (e.g. 6.2-rc-1), make sure that, when asked What is the next SNAPSHOT version?, you do not increment the snapshot version (i.e. you answer 6.2-SNAPSHOT instead of 6.3-SNAPSHOT or whatever suggestion you have). This is because the next step will ask you to create a stable branch where the final version (if this is the last RC we`re doing) will be released and there we need to keep the SNAPSHOT version to the current one.

If you have created the stable branch and are asked What is the next master version?, you will now increment the snapshot version (i.e. answer 6.3-SNAPSHOT) so that the master branch can move to the next development version.

Tip: Because the build process is a lenghty one (currently around 2 hours), it is a good idea to use the screen linux command. This is most helpful in case your Internet connection or electrical power drops. However, it is not in any way mandatory to use screen during the release.
# Perform the release from the release sources
[email protected]:~/releases/xwiki-trunks$ ~/maven-release.sh

Restart the release

If the build failed or if you wish to release again, perform the following steps:

  • Set the version that you're building, e.g. [email protected]:~/releases/xwiki-trunks$ export VERSION='4.2-milestone-3'
  • Navigate to the repositories that failed to build (e.g. xwiki-platform) and clean up. For example for xwiki-platform:
    [email protected]:~/releases/xwiki-trunks$ cd xwiki-platform
    [email protected]:~/releases/xwiki-trunks/xwiki-platform$ ~/restart-release.sh
  • Edit the maven-release.sh script and comment out the previously successfully released repositories so that you don't release them again.
    [email protected]:~/releases/xwiki-trunks/xwiki-platform$ cd ..
    [email protected]:~/releases/xwiki-trunks$ vim ~/maven-release.sh

    Go to the end of the maven-release.sh file and scroll up, until you reach this section:

    # Wrapper function that calls release_project for each XWiki project in order: commons, rendering, platform, enterprise, manager.
    # This is the main function that is called when running the script.
    function release_all() {
    ...

    Inside this method, comment out the previously successful top level projects and leave uncommented the top level projects that still need to be released, including the one we are resuming from. In this example, we are resuming from xwiki-platform but xwiki-commons and xwiki-rendering were already successfully released, so we are skipping them:

    ...
     echo              "*****************************"
     echo -e "\033[1;32m    Releasing xwiki-commons\033[0m"
     echo              "*****************************"
    #  release_project xwiki-commons
     echo              "*****************************"
     echo -e "\033[1;32m    Releasing xwiki-rendering\033[0m"
     echo              "*****************************"
    #  release_project xwiki-rendering
     echo              "*****************************"
     echo -e "\033[1;32m    Releasing xwiki-platform\033[0m"
     echo              "*****************************"
      release_project xwiki-platform
    ...
  • Fix the build if need be (you won't need to fix anything if you just want to release again for example).
  • Re-launch the maven-release.sh script from /releases/xwiki-trunks to resume from where we left off:
    [email protected]:~/releases/xwiki-trunks$ ~/maven-release.sh

If the release:prepare is good and you need to restart only the release:perform

The instructions below are not applicable for RC releases (that involve working with other branches than master and other additional operations). Would need additional steps to be complete, so it`s safer to just restart from the top level project that failed (i.e. rendering, platform, etc.).

Going even further with the resuming of a failed build, in the case of release:perform, we can resume from the actual failed module. To do so, we must make some additional temporary modifications to the release script, besides the one described above which isolates the script to release only the currently failed module.

This method only applies to a single failed project at a time (e.g. xwiki-platform). Make sure all other projects are commented out in the release_all method.

Do not run the ~/restart-release.sh command on the failed module because release:perform needs that information to be able to resume. Also, remember to cleanup after finishing with the release of the project at hand.

Comment out the cleanup steps done in the release_project method:

function release_project() {
  cd $1
#  pre_cleanup
#  update_sources
#  check_branch
#  create_release_branch
#  pre_update_parent_versions
  release_maven
   post_update_parent_versions
   push_release
...

Comment out the release:prepare step in the release_maven method and add the -rf group:artefactId parameter inside the -Darguments="..." with the module you want to resume the release from. See an example below where we are resuming from org.xwiki.platform:xwiki-platform-distribution-war.

function release_maven() {
 DB_PROFILE=hsqldb

 echo -e "\033[0;32m* release:prepare\033[0m"
# mvn release:prepare -DpushChanges=false -DlocalCheckout=true -DreleaseVersion=${VERSION} -DdevelopmentVersion=${NEXT_SNAPSHOT_VERSION} -Dtag=${TAG_NAME} -DautoVersionSubmodules=true -Phsqldb,mysql,pgsql,derby,jetty,glassfish,legacy,integration-tests,office-tests,standalone -Darguments="-N ${TEST_SKIP}" ${TEST_SKIP} || exit -2

 echo -e "\033[0;32m* release:perform\033[0m"
  mvn release:perform -DpushChanges=false -DlocalCheckout=true -P${DB_PROFILE},jetty,legacy,integration-tests,office-tests,standalone ${TEST_SKIP} -Darguments="-P${DB_PROFILE},jetty,legacy,integration-tests,office-tests ${TEST_SKIP} -Dgpg.passphrase='${GPG_PASSPHRASE}' -Dxwiki.checkstyle.skip=true -rf org.xwiki.platform:xwiki-platform-distribution-war" -Dgpg.passphrase="${GPG_PASSPHRASE}" || exit -2

 echo -e "\033[0;32m* Creating GPG-signed tag\033[0m"
...

Manually set the git tag name that will be used for GPG signing:

## The format is MODULE_NAME-VERSION. Modify accordingly.
export TAG_NAME="xwiki-platform-8.3-milestone-2"

Run the release script to resume the release of the current project:

[email protected]:~/releases/xwiki-trunks/xwiki-platform$ ~/maven-release.sh
Cleanup the release script by removing the temporary changes described in this section. This applies if you want to proceed to the next project (e.g. xwiki-enterprise) where the release needs to be executed properly.

Generate Code Contributors list

The following commands should be performed on the agent machine, after running the build (but can be run locally as well).
  • Automatically, on the agent:
    ## list_contributors.sh <start_version> <end_version>
    [email protected]:~/releases/xwiki-trunks$ ~/list_contributors.sh 10.4 10.5-rc-1
  • Manually (on the agent or locally, if the automatic option fails):
    • Collect the list of code contributors for this release by running the following command on each branch on each repository that has been released (xwiki-commons, xwiki-rendering, xwiki-platform):
      > git fetch --tags
      > git log --pretty=format:"%an" <previousTag>..<nextTag> | sort -u
      ## Example:
      > git log --pretty=format:"%an" xwiki-commons-10.4..xwiki-commons-10.5-rc1 | sort -u
      > git log --pretty=format:"%an" xwiki-rendering-10.4..xwiki-rendering-10.5-rc1 | sort -u
      > git log --pretty=format:"%an" xwiki-platform-10.4..xwiki-platform-10.5-rc1 | sort -u
      ## For **final versions**, always compare with the previous final, not with the previous RC:
      > git log --pretty=format:"%an" xwiki-platform-10.4..xwiki-platform-10.5 | sort -u
  • Try to remove duplicates and infrastructure users (like xwikirogci or XWiki) and sort alphabetically.
  • Update the Release Notes in the Credits section with the contributors list.

Handle Backward Compatibility Actions

Update Backward Compatibility in the release note

The Backward Compatibility report is automatically generated in the Release Notes page by the {{backwardCompatiblityReport version="<version>"/}} macro which does the following:

  • Gets the revapi ignores from the pom.xml of xwiki-commons, xwiki-rendering and xwiki-platform GitHub repositories and store them in an xobject in the Release Note page. If you wish to regenerate the content from GitHub just delete this xobject.
  • Displays the ignores

Update the backward compatibility setup in the build

If you're releasing a final version, perform the following operations on the agent or on your local machine:

  • Automatically, on the agent:
    ## backward_compatibility_cleanup.sh <previous_version> <new_version>
    [email protected]:~/releases/xwiki-trunks$ ~/backward_compatibility_cleanup.sh 10.4 10.5
  • Manually (on the agent or locally, if the automatic option fails):
    • Checkout master for xwiki-commons and edit the top level pom.xml to update the xwiki.compatibility.previous.version. Set the value to be your release you've just done.
      ## Replace the previous version with the new version (e.g. 10.4 with 10.5).
      [email protected]:~/releases/xwiki-trunks/xwiki-commons$ git checkout master
      [email protected]:~/releases/xwiki-trunks/xwiki-commons$ sed -i 's/<xwiki.compatibility.previous.version>10.4</<xwiki.compatibility.previous.version>10.5</' pom.xml
      ## Double check that it has been updated
      [email protected]:~/releases/xwiki-trunks/xwiki-commons$ git diff
      ## Commit and push
      [email protected]:~/releases/xwiki-trunks/xwiki-commons$ git commit -a -m "[release] Updated compatibility previous version to the one just released."
      [email protected]:~/releases/xwiki-trunks/xwiki-commons$ git push origin master
    • On master, you have to remove ignores from 3 locations and then commit & push the changes (git commit -a -m "[Misc] Removed revapi ignores from the previous version"):
      • xwiki-commons/xwiki-commons-core/pom.xml
      • xwiki-rendering/pom.xml
      • xwiki-platform/xwiki-platform-core/pom.xml
      • If you are doing this on the agent, you can use nano to open the files and use CTRL+W to search for revapi. Once you have found the JSON formatted ignores, select all the lines you want to delete by using CTRL+SHIFT+6 and press CTRL+K to delete the selected lines. Exit the exitor with CTRL+X, y, ENTER (when asked if the changes should be saved) and commit the changes for each repository.

Note that there's nothing to do on the stable branch since the branch will be used for bug fix releases and thus the xwiki.compatibility.previous.version value shouldn't be changed.

Blog post on xwiki.org

Create a new blog post on xwiki.org. You can have a look at the previous release blog posts for inspiration.

Update Wikimatrix

This step must be performed only for the latest final releases (not bugfixes or RCs).

Please ask a fellow committer for the credentials to Ludovic's account on Wikimatrix. (TODO: Add a better way of handling these credentials.)

Note: The only exception when a bugfix would be added here is when it would be done for the latest released final version (e.g. latest final is 10.2 and the bugfix is 10.2.1).

Announcement Mail

  • Send the announcement email to the devs list.
  • Example email:
    • Subject: [ANN] XWiki <version> released
    • Content:
      The XWiki development team is proud to announce the availability of XWiki <version>.
      <short summary>

      You can download it here: https://www.xwiki.org/xwiki/bin/view/Main/Download

      Make sure to review the release notes:
      https://www.xwiki.org/xwiki/bin/view/ReleaseNotes/Data/XWiki/<short version>

      Thanks for your support
      -The XWiki dev team

Forum Announcement

  • Add a new post to the users forum on https://forum.xwiki.org/c/News
    • Subject & Content: Same as for mail, but drop the [ANN] prefix
    • Category: News & Events
    • Tags: release

Announce on Twitter

To announce the new release on Twitter using XWiki.org`s account. Use the following type of text:

[email protected]:~$ twidge update "#XWiki 8.4.1 has been #released! Check it out: https://www.xwiki.org/xwiki/bin/view/ReleaseNotes/Data/XWiki/8.4.1"

Rebuild Debian Distribution

The XWiki Debian distribution is automatically rebuilt every day using a crontab on maven.xwiki.org.

However, in order for the Debian distribution to be ready when we announce a new version, it's a good thing to force rebuild it.

This is achieved by logging on maven.xwiki.org with the maven user. Then run the script.

nohup /home/maven/xwiki_scanpackages.sh &

This start the index update in the background, you can leave.

Force Extensions Update

In order to have up to date versions on https://extensions.xwiki.org you should trigger the Batch importer scheduler (from the first node of the cluster).

However before you do so, make sure to mute the IRC channel to not spam it:

/mode +q xwikibot

And don't forget to unmute it once the release is over:

/mode -q xwikibot

Update Docker

This should be done only for final versions (i.e. includes bufgixes)
  • Create an improvement issue on the XDOCKER project with subject Upgrade stable version to <version>.
  • Update the version of XWiki in the build.gradle file found in the XWiki Docker repository (clone it locally first).
    • To know how to generate the sha256, check the doc inside build.gradle. You need to download in advance the *.war file and run the according command in order to generate.
    • On Linux, use the following one-liner and replace the value of the VERSION variable accordingly:
      VERSION="9.11.8"; wget http://nexus.xwiki.org/nexus/content/groups/public/org/xwiki/platform/xwiki-platform-distribution-war/${VERSION}/xwiki-platform-distribution-war-${VERSION}.war && sha256sum xwiki-platform-distribution-war-${VERSION}.war && rm xwiki-platform-distribution-war-${VERSION}.war
  • Execute the Gradle build (run ./gradlew) to generate the various Dockerfiles and other resources for all image tags
  • Test the modified files. On Linux, you need to use sudo on each docker command or configure it differently.
    • Install Docker. For Mac you can check the installer.
    • Make sure you open Docker before running the commands.
      • Linux (except Ubuntu): sudo systemctl start docker
    • docker network create -d bridge xwiki-test
    • docker run --net=xwiki-test --name mysql-xwiki-test -v /tmp/xwiki-docker-test/mysql:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=xwiki -e MYSQL_USER=xwiki -e MYSQL_PASSWORD=xwiki -e MYSQL_DATABASE=xwiki -d mysql:5.7 --character-set-server=utf8 --collation-server=utf8_bin --explicit-defaults-for-timestamp=1
    • Navigate to the directory to test, e.g. 10/mysql-tomcat and issue:
      • docker build -t xwiki-test .
      • docker run --net=xwiki-test --name xwiki-test -p 8080:8080 -v /tmp/xwiki-docker-test/xwiki:/usr/local/xwiki -e DB_USER=xwiki -e DB_PASSWORD=xwiki -e DB_DATABASE=xwiki -e DB_HOST=mysql-xwiki-test xwiki-test
        Note that same as for mysql container above you'll need to remove the container if it already exists.
        • In case you had an XWiki instance running on 8080 and the above command fails (i.e. address already in use), you cannot simply run it again. If you do (and you should try, actually), will try to recreate the container with the xwiki-test name that is now already in use by a container for which you are given the ID (note that down). Instead, you need to simply start the mentioned container ID which previously failed by running docker start <FAILED_START_CONTAINER_ID>.
    • Open your browser to http://localhost:8080 and try to setup XWiki and verify it works
  • If all is ok commit, push and close the jira issue created above
  • Note down the SHA1 of the last commit and update https://github.com/docker-library/official-images/blob/master/library/xwiki with it by creating a Pull Request (you can edit directly on the GitHub web page and create a Pull Request).
  • If you need to update the official documentation create a Pull Request for https://github.com/docker-library/docs/blob/master/xwiki/content.md (you can edit directly on the GitHub web page and create a Pull Request).
  • Clean up by running the following in a shell:
    docker stop xwiki-test
    docker rm xwiki-test
    docker stop mysql-xwiki-test
    docker rm mysql-xwiki-test
    docker network rm xwiki-test
    docker rmi xwiki-test
    sudo rm -Rf /tmp/xwiki-docker-test

Crash course on Docker:

Docker can create Images based on a Dockerfile (or a Compose file). Docker can also download Images from the DockerHub repository. Docker can create Containers from images. Docker also creates internal Volume unless you create mapped Volumes on your host computer so that you can navigate in them as local directories.

  • docker run creates a container locally based on an existing docker image.
  • docker ps lists the ids of running containers
  • docker ps -a lists the ids of all containers (running or not)
  • docker start <id> starts an existing container
  • docker stop <id> stop a running container
  • docker rm <id> removes an existing container
  • docker volume ls lists existing volumes
  • docker volume rm removes an existing volume
  • docker system prune removes unused data
  • docker network create creates a docker network so that several containers can see each other
  • docker network ls lists existing docker networks
  • docker network rm <id> removes an existing docker network
  • docker images lists all local images
  • docker rmi <id> removes an existing local image
