Re-use agent in parallel stages of declarative pipeline












0















I'm using Declarative Pipelines 1.3.2 plugin and I want to use the same agent (as in only specifying the agent directive once) in multiple parallel stages:



stage('Parallel Deployment')
{
agent { dockerfile { label 'docker'; filename 'Dockerfile'; } }
parallel
{
stage('A') { steps { ... } }
stage('B') { steps { ... } }
}
}


However, Jenkins complains:




"agent" is not allowed in stage "Parallel Deployment" as it contains parallel stages




A solution is to duplicate the agent directive for each parallel stage, but this is tedious and leads to lot of duplicated code with many parallel stages:



stage('Parallel Deployment')
{
parallel
{
stage('A') {
agent { dockerfile { label 'docker'; filename 'Dockerfile'; } }
steps { ... }
}
stage('B') {
agent { dockerfile { label 'docker'; filename 'Dockerfile'; } }
steps { ... }
}
}
}


Is there a more idiomatic solution, or is duplicating agent directive necessary for each of the parallel stages?

    Are you not able to declare the agent at Pipeline level so all stages run on the same agent ?

  • You are totally correct; if this was the answer, I'd accept it now.
