Cannot hijack task container that is based on oci-build-task

[holgerstolzenberg]

Problem described in summary.

Task file:

---
platform: linux

inputs:
  - name: pull-request
    path: .

image_resource:
  type: registry-image
  source:
    repository: vito/oci-build-task
    tag: 0.4.0

caches:
  - path: cache

run:
  path: build

When the task failed I tried to hijack the container and git this:

Looks like bash is missing in $PATH

Okay - I wasn´t aware that the default command of hijack can be changed. I was able to access the container.
Still you might want to consider adding bash to the image.

[vito]

This will be handled in future versions of Concourse which fall back to sh if bash doesn't exist. Should be in Concourse v7+ - it's already in master.

I could add bash to the image but it might be shortlived if we switch to kaniko-based building (#46), which requires the image to be essentially empty. Would prefer to rely on Concourse's feature change for now. Thanks!
