[Request] Have a task supporting the bash commands

[cmoulliard]

Feature request

The goal of this request is to have a task supporting the execution of multiple bash commands as we can by example do using CircleCI. See : https://github.com/snowdrop/component-operator-demo/blob/master/.circleci/config.yml#L26-L32

Tekton currently proposes this approach: https://github.com/tektoncd/pipeline/blob/master/examples/taskruns/task-env.yaml
but we can't group the commands to be executed by a container as currently it is restricted to what the k8s container spec allows

A workaround is perhaps to mount the bash script to be executed OR to have a parser converting a multiline bash commands into x args

A workaround that I use is:

command: ["bash", "-c", "command 1 ; command 2"]

But it would be nice to have a proper way to do multiple commands at once.

@cmoulliard I think the related issue in pipeline is tektoncd/pipeline#1432, and thus I feel we can close this one 👼

[cmoulliard]

Yes.
