Description

Hi, after upgrading our Jenkins server to 2.289.2 and upgrading all plugins the ssh-agent plugin does not work inside a Kubernetes container block. 

This works

node('kubernetes') {

 

 sshagent(['mykey']) {

   sh "ssh ..."

 }

 

}

This does not work

 

node('kubernetes') {

 container('jnlp') {

 sh 'which ssh-agent'

   sshagent(['mykey']) {

     sh "ssh ..."

   }

  }

 

}
