Hi,
I have pipeline job that uses ssh agent step to set up credentials to
connect to git repository and clone it. When i execute the job on the
master jenkins, it runs flawlesly. When run it on a slave it fails because
ssh agent closes before the git clone.
This is an example of the code that produces the error:
node
{
def credentials = 'somecredentials'
sshagent (credentials: [credentials])
{
sh ( script:"""
rm -rf common_jenkins_jobs
git clone ssh://[email protected]
""")
}
}
node ( "ci-server-slave" )
{
def credentials = 'somecredentials'
sshagent (credentials: [credentials])
{
sh ( script:"""
rm -rf common_jenkins_jobs
git clone ssh://[email protected]
""")
}
}
The first block runs on the master node and the seccond on the slave.
Examing the execution logs of the first block you can see the sequence:
1. ssh-agent start
2. rm
3. git
4. ssh-agent stop
but the part that runs on the slave shows the sequence:
1. ssh-agent start
2. ssh-agent stop
3. rm
4. git
leaving the git clone out of the ssh-agent environment and failing due to
lack of crecedentials.
I attached the log of the second node on a simpler test where the sh step
only runs an ls ltr command. There you can clearly see that the ls command
runs after the ssh-agent ends.
¿ Can this behaviour be part of some missconfiguration on my part or is a
bug on the ssh agent step ?
