action-setup-kube-tools

A GitHub Action that setup Kubernetes tools (kubectl, kustomize, helm, kubeconform, conftest, yq, rancher, tilt, skaffold, kube-score) and cache them on the runner. It is like a typescript version of stefanprodan/kube-tools with no command input param, but as compared with it, it's very fast as it installs the tools asynchronously.

Usage

Inputs

Parameter	Required	Default Value	Description
fail-fast	false	true	the action immediately fails when it fails to download (ie. due to a bad version)
arch-type	false	amd64	The processor architecture type of the tool binary to setup. Supported types are only amd64 and arm64. If a type other than the supported Types is specified, it will be treated as amd64.
setup-tools	false	""	List of tool name to setup. By default, the action download and setup all supported Kubernetes tools. By specifying setup-tools you can choose which tools the action setup. Supported separator is return in multi-line string. Supported tools are kubectl, kustomize, helm, helmv3, kubeval, conftest, yq, rancher, tilt, skaffold, kube-score
kubectl	false	1.24.10	kubectl version. kubectl vesion can be found here
kustomize	false	5.0.0	kustomize version. kustomize vesion can be found here
helm	false	3.11.1	helm version. helm vesion can be found here
kubeval	false	0.16.1	kubeval version (must be 0.16.1+). kubeval vesion can be found here. NOTE: this parameter is deprecating as kubeval is no longer maintained. A good replacement is kubeconform. See also this for more details.
kubeconform	false	0.5.0	kubeconform version. kubeconform vesion can be found here
conftest	false	0.39.0	conftest version. conftest vesion can be found here
yq	false	4.30.7	yq version. yq vesion can be found here
rancher	false	2.7.0	Rancher CLI version. Rancher CLI vesion can be found here
tilt	false	0.31.2	Tilt version. Tilt vesion can be found here
skaffold	false	2.1.0	Skaffold version. Skaffold vesion can be found here
kube-score	false	1.16.1	kube-score version. kube-score vesion can be found here

• Supported Environments: Linux
• From v0.7.0, the action supports tool version 'v' prefix. Prior to v0.7.0, the action only accept the tool version without 'v' prefix but from v0.7.0 the action automatically add/remove the prefix as necessary

Outputs

Parameter	Description
kubectl-path	kubectl command path if the action setup the tool, otherwise empty string
kustomize-path	kustomize command path if the action setup the tool, otherwise empty string
helm-path	helm command path if the action setup the tool, otherwise empty string
kubeval-path	kubeval command path if the action setup the tool, otherwise empty string
kubeconform-path	kubeconform command path if the action setup the tool, otherwise empty string
conftest-path	conftest command path if the action setup the tool, otherwise empty string
yq-path	yq command path if the action setup the tool, otherwise empty string
rancher-path	rancher command path if the action setup the tool, otherwise empty string
tilt-path	rancher command path if the action setup the tool, otherwise empty string
skaffold-path	rancher command path if the action setup the tool, otherwise empty string
kube-score-path:	rancher command path if the action setup the tool, otherwise empty string

Sample Workflow

Specific versions for the commands can be setup by adding inputs parameters like this:

  test: 
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v2
    - uses: yokawasa/action-setup-kube-tools@v0.11.2
      with:
        kubectl: '1.25'
        kustomize: '5.0.0'
        helm: '3.11.1'
        kubeconform: '0.5.0'
        conftest: '0.39.0'
        rancher: '2.7.0'
        tilt: '0.31.2'
        skaffold: '2.1.0'
        kube-score: '1.16.1'
    - run: |
        kubectl version --client
        kustomize version
        helm version
        kubeconform -v
        conftest --version
        yq --version
        rancher --version
        tilt version
        skaffold version
        kube-score version

Default versions for the commands will be setup if you don't give any inputs like this:

  test: 
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v2
    - uses: yokawasa/action-setup-kube-tools@v0.11.2
    - run: |
        kubectl version --client
        kustomize version
        helm version
        kubeconform -v
        conftest --version
        yq --version
        rancher --version
        tilt version
        skaffold version
        kube-score version

By specifying setup-tools you can choose which tools the action setup. Supported separator is return in multi-line string like this

  test: 
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v2
    - uses: yokawasa/action-setup-kube-tools@v0.11.2
      with:
        setup-tools: |
          kubectl
          helm
          kustomize
          skaffold
        kubectl: '1.25'
        helm: '3.11.1'
        kustomize: '5.0.0'
        skaffold: '2.1.0'
    - run: |
        kubectl version --client
        kustomize version
        helm version
        skaffold version

By specifying arch-type you can choose the processor architecture type of the tool binary to setup. Supported types are only amd64(default) and arm64.

  test: 
    steps:
    - uses: actions/checkout@v4
    - uses: yokawasa/action-setup-kube-tools@v0.11.2
      with:
        arch-type: 'arm64'
        setup-tools: |
          kubectl
          helm
          kustomize
          skaffold
        kubectl: '1.25'
        helm: '3.11.1'
        kustomize: '5.0.0'
        skaffold: '2.1.0'
    - run: |
        kubectl version --client
        kustomize version
        helm version
        skaffold version

Developing the action

Install the dependencies

npm install

Build the typescript and package it for distribution by running ncc

npm run build && npm run format && npm run lint && npm run pack

Finally push the results

git add dist
git commit -a -m "prod dependencies"
git push origin releases/v0.11.2
