Dot

A minimal CI. Designed to be local first.

All the jobs run inside docker containers. Dot communicates with the Docker daemon using the Docker client API.

Refer the project wiki to learn more about dot.

Features

• Single binary, can run anywhere, on your machine or CI/CD systems
• Multi stage builds with support for build artifacts
• Simple yaml job definition
• Bring your own Docker images. Supports private registries
• Uses plain Docker
• Supports conditional evaluation using expressions

Installation

Get the latest version from the releases section.

The latest version can also be installed using go.

go install github.com/opnlabs/dot@latest

Run using Docker

Example

This example uses GoReleaser to build this project.

stages:
  - test
  - security
  - build

jobs:
  - name: Run tests
    stage: test
    image: "docker.io/golang:1.21.3"
    variables:
      - TEST: true
    script:
      - go test ./...
    condition: TEST

  - name: Run checks
    stage: security
    image: "docker.io/golangci/golangci-lint:latest"
    script:
      - golangci-lint run ./...

  - name: Build using Goreleaser
    stage: build
    image: "docker.io/golang:1.21.3-bookworm"
    script:
      - git config --global safe.directory '*'
      - curl -sfL https://goreleaser.com/static/run | bash -s -- build --snapshot
    artifacts:
      - dist

Extract the binary once the build is complete.

tar xvf .artifacts/artifacts-*.tar
dist/dot_linux_amd64_v1/dot version

Build Dot with Dot

This project can be built with Dot. The dot.yml file describes all the jobs necessary to build a linux binary. Clone the repo and run

go run main.go -m

This should create an artifact tar file in the .artifacts directory with the linux binary dot. The -m flag gives dot access to the host's docker socket. This is required only if containers are created within dot.
