Build and Push Action

This project contains a custom GitHub Action that builds and pushes Docker images using the Harness Drone CI plugin.

Overview

This action is designed to help automate Docker image builds and push operations, triggered within a Drone CI pipeline. By utilizing the plugins/github-actions:0.0.3, the action can be configured to run privileged tasks, including the building and pushing of Docker images to DockerHub.

Prerequisites

DockerHub Account: Ensure you have a valid DockerHub account and store your credentials securely in the pipeline secrets.
Drone CI: Make sure that you have Harness drone plugin configured in your project.
GitHub Token: You will need a GitHub token stored in the Drone secrets for authentication during the action execution.

Usage

Here’s how you can use the action in your Drone CI pipeline:

- step:
    type: Plugin
    name: Private Action
    identifier: private_action
    spec:
      connectorRef: account.DockerHubKroon
      image: plugins/github-actions:0.0.3
      privileged: true
      settings:
        uses: gregkroon/buildandpushaction@v1
        with:
          dockerfile: ./Dockerfile
          context: .
          image_name: munkys123/actions-golang
          username: munkys123
          password: <+secrets.getValue("account.dockerhubkroon")>
          tags: <+pipeline.sequenceId>
        env:
          GITHUB_TOKEN: <+secrets.getValue("gittoken")>
      runAsUser: "0"
      resources:
        limits:
          memory: 8G
          cpu: 2000m

Step Breakdown

type: Plugin: Indicates the use of a Drone plugin.
image: Specifies the plugin image to use, in this case, the plugins/github-actions with version 0.0.3.
privileged: true: Ensures the step runs with the necessary permissions to use Docker-in-Docker (DinD).
settings: These are passed to the GitHub Action:
- dockerfile: Path to the Dockerfile.
- context: Directory context for the Docker build.
- image_name: The name of the Docker image to be pushed.
- username and password: DockerHub credentials pulled from Drone secrets.
- tags: Dynamically generated tags for the Docker image.
env: Environment variables, including the GITHUB_TOKEN required for accessing GitHub.
resources: Specifies the resource limits for the build step (8GB memory, 2000m CPU).

Secrets

You will need to configure the following secrets in Drone CI:

account.dockerhubkroon: DockerHub credentials.
gittoken: GitHub token for authentication.
