Fix for broken Kubernetes mode

[timmjd]

Issue

Within the current implementation of hooks 0.4.0 in combination with ARC 0.6.1 running in mode=kubernetes and the lastest runner 2.311.0 on an Enterprise instance, the handover of args towards the k8s job container is buggy. The args will be forwarded to the job pod in a escaped way, which will be disrespected by some tools like mkdocs:

Usage: mkdocs [OPTIONS] COMMAND [ARGS]...

  MkDocs - Project documentation with Markdown.

Options:
  -V, --version  Show the version and exit.
  -q, --quiet    Silence warnings
  -v, --verbose  Enable verbose output
  -h, --help     Show this message and exit.

Commands:
  build      Build the MkDocs documentation
  gh-deploy  Deploy your documentation to GitHub Pages
  new        Create a new MkDocs project
  serve      Run the builtin development server

This fix will remove the leading and ending quotes from the args before handing over to the k8s pod creation.

Example 1

The args as an array with all parameters as a space separated string

action.yml

name: Build MKDocs

runs:
  using: docker
  image: docker://squidfunk/mkdocs-material:latest
  entrypoint: mkdocs
  args:
  - build --verbose --strict

Runner to Hooks

["\"build","--verbose","--strict\""]

Pod config without fix

  containers:
  - image: squidfunk/mkdocs-material:latest
    command:
    - mkdocs
  - args:
    - '"build'
    - --verbose
    - --string"

Pod config with fix

spec:
  containers:
  - image: squidfunk/mkdocs-material:latest
    command:
    - mkdocs
    args:
    - build
    - --verbose
    - --strict

Example 2

The args as an array with each parameter as a separate string

action.yml

name: Build MKDocs

runs:
  using: docker
  image: docker://squidfunk/mkdocs-material:latest
  entrypoint: mkdocs
  args:
  - build
  - --verbose
  - --strict

Runner to Hooks

["\"build\"","\"--verbose\"","\"--strict\""]

Pod config without fix

  containers:
  - image: squidfunk/mkdocs-material:latest
    command:
    - mkdocs
  - args:
    - '"build"'
    - '"--verbose"'
    - '"--strict"'

Pod config with fix

spec:
  containers:
  - image: squidfunk/mkdocs-material:latest
    command:
    - mkdocs
    args:
    - build
    - --verbose
    - --strict
