Existing installations of CloudBees CI on traditional platforms and CloudBees CD/RO can take advantage of the analytics capabilities of CloudBees Analytics.
The installation of CloudBees Analytics to your existing CloudBees CD/RO and CloudBees CI environments is a process involving the following sequential steps:
Pre-installation requirements
-
Contact CloudBees Support to obtain the executable files for the CloudBees Software Delivery Automation and CloudBees Analytics installers.
Upgrading CloudBees CI on traditional platforms
Before upgrading
Before upgrading, take a snapshot of your CloudBees CI platform for the operations center and every controller:
-
Generate a support bundle. It will help if there are problems with the upgrade or to know what plugins were upgraded in the process.
-
Backup your instance before starting the upgrade. The minimal backup is a copy of your
${JENKINS_HOME}
directory. If theBUILD_DIRECTORY
is out of the${JENKINS_HOME}
, you must back it up as well.If something unexpected occurs, the rollback process is based on the backup of your instance.
-
Upgrade your plugins before starting the upgrade. Run tests after upgrading the plugins to ensure the upgrades are functioning as expected.
For client controllers that are connected to the operations center:

Key principles to follow when upgrading
Change one thing at a time
Limit the changes you make to one area at a time. For example, do not plan to make infrastructure changes such as hardware upgrades, networking changes, or OS package upgrades when upgrading Jenkins. This helps to identify and isolate the root cause of any issues you encounter.
Backup strategies
CloudBees recommends the following backup strategies:
-
Ensure you have regular backups of your
JENKINS_HOME
for the operations center and all controllers.CloudBees recommends using the CloudBees Backup Plugin plugin to automate this. controllers that have the CloudBees Backup Plugin 3.38 or later installed have support for the
Restore job type
.-
To restore an operations center when using CloudBees Software Delivery Automation, follow the steps for Restore backup files manually.
The backups should be stored at an offsite location such as cloud storage or, at a minimum, on separate hardware from your CloudBees CI.
-
-
Take another backup immediately before you start the upgrade.
-
Test the backup to verify it is valid.
The backup is used to recover from a failure if you encounter a severe issue during the production upgrade.
After an upgrade of the Jenkins core version or plugins, you cannot directly downgrade the
war
file and plugins. The only way to roll back is to restore theJenkins_HOME
backup.To validate the integrity of the backup, it is essential to extract the backup to another filesystem and verify the checksums using:
find $JENKINS_HOME -type f | sort | xargs md5sum >~/checksum.log.backup
Run this for both the live and backup data, and compare the
checksum.log.*
between the two.
Test strategies
CloudBees recommends the following test strategies:
-
Create a separate test environment that has a similar setup as your production environment with representative jobs.
If you are creating a test environment and require a license, please send CloudBees the instance ID for your test instance, and CloudBees will send you a test instance license. -
Create jobs on your test controller that are representative of jobs on your production controller. This allows you to test the upgrade using the key plugins for your workflow and interactions with any external systems such as SCM tools, artifact repositories, bug trackers, and cloud automation.
It is a best practice to create jobs that are a subset of representative jobs on the test cluster. These dedicated jobs represent your production jobs, but without working on real data. CloudBees recommends talking to your development groups to find jobs that cover the primary functionality, such as:
-
Test your end-to-end complex pipeline jobs.
-
Test jobs that utilize critical plugins.
-
Run jobs that are part of integrations.
-
Run jobs that are for specific technologies.
To clone a production controller to a test controller, follow the steps from Migration Guide: CloudBees CI, specifically the section titled, Case B - Migrate Entire Jenkins Configuration, Including Jobs.
-
-
Update the test configuration for some representative jobs so they do not collide with your production jobs. Then, run the test jobs to ensure they work correctly in the upgraded test instance. You will need to recreate credentials on your test instance.
This test environment can also be useful after the upgrade to test the installation of new plugins.
Recommendations
Set up a test environment
This is ideally a full test environment with the operations center and client controllers and requires a test license
. If this is not feasible, using a test controller with representative jobs will work.
Enable the CloudBees Assurance Program (CAP)
Verify CAP is enabled to avoid plugin dependency issues or incorrect versions installed.
Upgrade to the latest version
CloudBees recommends that you always upgrade to the latest version of your CloudBees product, ensuring wider lifecycle support coverage, plus more security patches added via the CloudBees Security Advisory, resolved issues, and new features.
Upgrade the instance where it is running
CloudBees highly recommends that you:
-
Upgrade Jenkins to the same location where it is currently running, even for production environments.
-
Perform a backup of
$JENKINS_HOME
and the$BUILD_DIR
, in case it is not in the default location. This should allow you to revert to the previous state.
CloudBees does not recommend that you keep two different instances running at the same time. This may be done to avoid downtime while performing the upgrade. However, unless you really know what you are doing, it is very difficult to replicate the exact same environment. For example:
-
The JNLP agent does not work correctly as the
$JENKINS_URL
because the location is different. -
Credentials may fail if the secret is not the same for both instances.
-
The OS may not be configured in the same way. For example,
ulimit
. -
The CloudBees CI configuration may not be correctly replicated.
Stop using Apache Maven builds
The Maven Integration plugin is not recommended because it is considered unreliable by the Jenkins Community.
End-of-life announcement CloudBees has determined that this plugin will be removed from the CloudBees Assurance Program (CAP) in late 2022. Notification will be provided prior to the removal of the plugin. Please contact CloudBees Support if you have any concerns or questions. |
CloudBees recommends that you migrate jobs using the Maven Integration plugin to Pipeline Jobs using the Pipeline Maven Integration plugin.
If you are able to migrate your jobs, please carefully read the Maven jobs and Java versions compatibility guide.
Upgrade process
Visit the downloads page. Select your desired distribution type and review the instructions below.
-
Java WAR file
-
Ubuntu/Debian
-
Red Hat / CentOS
-
OpenSuse
-
Microsoft Windows
-
Docker
Java WAR file
If your CloudBees CI instance is run with the command java -jar cloudbees-core-cm.war
or java -jar cloudbees-core-oc.war
, you can simply replace the jenkins.war
file with the latest version.
Ubuntu/Debian
-
Operations center -
apt-get update && apt-get install cloudbees-core-oc
-
Controller -
apt-get update && apt-get install cloudbees-core-cm
Red Hat/CentOS
Beginning in CloudBees CI on traditional platforms version 2.319.1.5, the epel-release
package is required to upgrade CloudBees CI on traditional platforms using an RPM, however some CentOS distributions do not include it.
For those CentOS distributions, run the following command before you begin the installation procedure: sudo yum install epel-release
.
-
Operations center -
yum upgrade cloudbees-core-oc
-
Controller -
yum upgrade cloudbees-core-cm
RPM/YUM with High Availability: The RPM package contains a post-install script to ensure ownership on several files including To address this problem, you can skip this script by adding the property |
OpenSUSE/SUSE Linux
-
Operations center -
zypper install cloudbees-core-oc
-
Controller -
zypper install cloudbees-core-cm
Microsoft Windows
To upgrade on Microsoft Windows servers, a new .zip
must be downloaded from the downloads page and installed.
Servlet container
Once a .war
archive has been downloaded, follow the servlet container’s existing application deployment process.
When using servlet containers, CloudBees CI will set the JENKINS_HOME
to the $APP_SERVER_USER/.jenkins/
folder.
If the servlet container installation does not include write permissions to this folder for this user (sometimes done for security), you must either grant appropriate permissions or override this setting by adding the -DJENKINS_HOME=$MY_JENKINSPATH
argument in your servlet container startup. Refer to the servlet container’s documentation for how to add startup arguments.
Tomcat
Use environment variable CATALINA_OPTS
to add:
-
-Dorg.apache.tomcat.util.buf.UDecoder.ALLOW_ENCODED_SLASH=true
. -
-Dorg.apache.catalina.connector.CoyoteAdapter.ALLOW_BACKSLASH=true
which is needed for the Blue Ocean plugin.
CloudBees recommends that you configure it in the script $CATALINA_BASE/bin/setenv.sh
(Linux) or %CATALINA_BASE%\bin\setenv.bat
(Microsoft Windows) that you’ll create to customize your application server.
Upgrade steps
Before you upgrade
-
Ensure you have enabled the CloudBees Assurance Program (CAP) to ensure you are upgrading to plugin versions tested by CAP. For more information, please refer to Upgrading plugins with Beekeeper Upgrade Assistant.
-
Enable the CloudBees Quiet Start Plugin plugin to ensure that when the instance first comes online after the upgrade, builds will not start automatically before you get a chance to upgrade the plugins.
-
Verify the test environment is functioning correctly after it is upgraded.
-
Ensure you have taken a backup.
-
Verify all running builds are complete.
-
Java 11 is recommended for your Jenkins instance, the operations center, Jenkins controllers, and all agents for Jenkins LTS 2.303.3. For more information, refer to the upgrade guide.
CloudBees strongly recommends that you upgrade to Java 11 as soon as possible. The ability to run new versions of the product on Java 8 will be removed in an upcoming release. Releases that occurred during the support window for Java 8 will continue to run on Java 8. |
Recommended steps
-
Upgrade the plugins on the operations center.
-
Select
. -
Verify that Enroll this instance in the CloudBees Assurance Program is selected.
-
Verify that Allow automatic upgrades of plugins on restart is selected.
-
Select Save.
-
Navigate to
and under the Updates tab, select upgrade all plugins. -
Restart the operations center.
-
-
After your controllers are upgraded, you must manually upgrade the
agent.jar
file for any inbound agents that are not configured to upgrade theagent.jar
file automatically. For more information, refer to Windows agent offline or unable to connect.-
SSH-connected agents upgrade the
agent.jar
automatically. -
You can enable automatic upgrades for inbound agents by Upgrading Windows Service Wrapper.
-
-
Now that you are running the latest version of CloudBees CI, CloudBees recommends you enable actionable build notifications in GitHub, Bitbucket, and Slack. This generally takes a few minutes and provides enhanced notifications for your developers with no Pipeline changes required. For more information, refer to Setting up actionable build notifications in Slack.
-
When updating your controllers, CloudBees recommends that you install the Health Advisor by CloudBees plugin, if not already installed. The CloudBees Jenkins Health Advisor automatically identifies issues that could impact the performance, stability, and security of your controller. It also identifies potential issues due to known issues on your controller. You are notified via email when a new problem is found and the email includes links to the solutions for the identified issues. For instructions, refer to Jenkins Health Advisor by CloudBees.
If you are using the High Availability (HA) feature, the general process for updating the HA operations center or any HA controller is:
-
Stop both HA nodes.
-
Upgrade both HA nodes.
-
Start one of the HA nodes and wait for it to come fully online.
-
Update the plugins according to CAP recommendations and restart.
-
Start the other HA node.
-
