Issue
- Find the name of the Cloud that a docker agent belong to
Environment
- Jenkins
- CloudBees Jenkins Enterprise - Managed Master (CJEMM)
- CloudBees Jenkins Team (CJT)
- CloudBees Jenkins Platform - Client Master (CJPCM)
- Docker plugin
- Yet Another Docker plugin
Resolution
The agents provisioned by both the Yet Another Docker plugin and the Docker plugin contains the name of the Cloud that is configured globally:
They automatically join the cloud name and the container id as following: <dockerCloudName>-<agentId>. You can therefore use a regexp on the variable ${NODE_NAME} to extract the <dockerCloudName> part:
def getDockerCloudName(dockerNodeName) {
return ("${dockerNodeName}" =~ /(.*)-([a-z0-9]+)/)[0][2];
}
node ('myDockerLabel') {
echo "${getDockerCloudName(env.NODE_NAME)}"
}
Example of the output:
Started by user admin
[Pipeline] node
Running on myDockerLabel-a55e069acece in /home/jenkins/workspace/testDir
[Pipeline] {
[Pipeline] echo
a55e069acece
[Pipeline] }
[Pipeline] // node
[Pipeline] End of Pipeline
Finished: SUCCESS
