run azuredevops task in all agents of the specified pool

Question

Is there any way to make the pipelie task/job to run in all the agents of the agent pool ?

I am planning to create a release pipeline and scheduled once in every week, which is for cleaning up the build agents from unused docker images which are older than 3 months. so I got the command for the same and created one release pipeline with the "commandline" task with the command "docker image prune --all --filter "until=720h". But here we have multiple agents in the each pool and i have to ensure that this task is executed across all the agents in the specified pools. How can i Achieve this

Answer 1

You could create a pipeline with multiple Stages and run every stage on each agent.

trigger:
- main

pool:
  vmImage: ubuntu-latest

stages:
- stage: agent1
  pool: 
   name: AgentPoolName
   demands:
    - agent.name -equals agent1
  jobs:
  - job: docker1
    steps:
    - script: docker image prune --all --filter "until=720h

- stage: agent2
  pool: 
   name: AgentPoolName
   demands:
    - agent.name -equals agent2
  jobs:
  - job: docker2
    steps:
    - script: docker image prune --all --filter "until=720h
