slask-action

Deploy scripted kubernetes applications without dependencies

to convert your yaml deployments to json/slask deployments you can try https://yaml-converter.knatofs.se/

example action.yaml:

jobs:
  slask:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v3
    - name: Deploy scripted application
      uses: matst80/slask-action@main
      with:
        k8sConfig: ${{ secrets.K8S_CONFIG }}
        scriptPath: deploy.cjs

if you need to test the action without github actions you can use npx ts-kubernetes-action deploy.cjs '{"sha":"1231234"}' last parameter is the github context if that is used in the deployment file, f.ex. git sha and it's not needed.

then the deployment script file /deploy.cjs

/** @type {import('ts-kubernetes-action').DeploymentConfig} */
module.exports = async (k8s, { sha }) => {
  const namespace = "default";
  const labels = { app: "example" };

  await k8s.createDeployment(namespace, {
    metadata: {
      name: "example",
      labels,
    },
    spec: {
      replicas: 1,
      selector: {
        matchLabels: labels,
      },
      template: {
        metadata: {
          labels,
        },
        spec: {

              imagePullPolicy: "Always",
              ports: [

              ],
              resources: {

              },
            },
          ],
        },
      },
    },
  });
  await k8s.createService(namespace, {
    metadata: {
      name: "example",
    },
    spec: {
      selector: labels,
      ports: [
        {
          port: 8080,
        },
      ],
    },
  });
  await k8s.createIngress(namespace, {
    metadata: {
      name: "example",

    spec: {

                    name: "example",
                    port: {
                      number: 8080,
                    },
                  },
                },
              },
