kaniko-action

Build and optionally push Docker images in Kubernetes using Kaniko without access to docker.sock.

This action allows you to build container images using Kaniko in Forgejo workflows. You can also optionally push the built images to a registry.

Note: Kaniko requires a privileged container.

Example Workflow

Here's an example of how to use this action in your workflow:

name: Build and Push Docker Image

on:
  push:
    branches:
      - main

jobs:
  build:
    runs-on: flakes-action
    steps:
      - name: Checkout repository
        uses: actions/checkout@v4

      - name: Build and push
        uses: https://code.252.no/tommy/kaniko-action@latest
        with:
          cache: false
          context: /workspace/${{ github.repository }}
          credentials: |
            code.252.no=${{ github.repository_owner }}:${{ secrets.REGISTRY_TOKEN }}            
          destinations: "code.252.no/tommy/mbpfan:${{ steps.meta.outputs.tags }}"
          push: 'true'

In this example, the action builds the Docker image defined in Dockerfile located at the root of the repository, and pushes it to myregistry.com/myimage:latest.
