Wanted to know if there is any flag/option for concourse tasks inside a single job so that all tasks gets executed regardless of any task failing.

Thanks!

Totally. By default, tasks run sequentially. If you want them to run independently of the sequence place them in the in_parallel key, like in the following pipeline:

jobs:
  - name: parallel-tasks
    plan:
    - in_parallel:
      - task: failing-task
        config:
          platform: linux
          image_resource:
            type: docker-image
            source:
              repository: alpine
          run:
            path: /bin/sh
            args: [ "-c", "exit 1"]
      - task: passing-task
        config:
          platform: linux
          image_resource:
            type: docker-image
            source:
              repository: alpine
          run:
            path: /bin/sh
            args: [ "-c", "exit 0"]

Running it will produce the following output: parallel tasks

in_parallel works with tasks as well as resources (e.g. running get in parallel)

    Thanks oozie! Exactly the thing I was looking for. Much appreciated :) – Aswin Ramanath Feb 23 '22 at 09:05
  • But what if you want them sequential still but run a task after a certain has failed? there's "ensure" but that's not a task .. For example you want to "put" some data to s3 after a certain task .. even on failure. – trainoasis Dec 09 '22 at 16:22
