Build an Image from a Different Git Repository

Build microservices from other repositories

In most cases, your Codefresh pipeline will checkout a single Git repository. Codefresh also has great support for Monorepos if you have placed all your applications in a single repository.

A Codefresh pipeline is not really tied to a specific git repository, which means that by checking out multiple git repositories you can build docker images from other unrelated repositories in a single pipeline if you wish to do so.

Building Docker images from other Git repositories

Here is a Codefresh pipeline that checks out two micro-services from two separate Git repositories.

And here is the pipeline definition.

codefresh.yml

version: '1.0'
stages:
  - 'clone phase'
  - 'build phase'
steps:
  checkoutApp1:
    title: 'Cloning first repository...'
    type: git-clone
    repo: kostis-codefresh/example_nodejs_postgres
    revision: experiment1
    git: github
    stage: 'clone phase'
  checkoutApp2:
    title: 'Cloning second repository...'
    type: git-clone
    repo: kostis-codefresh/trivial-go-web
    revision: master
    git: github
    stage: 'clone phase'
  myFirstDockerImage:
    title: 'Building Microservice A'
    type: build
    dockerfile: Dockerfile
    image_name: my-nodejs-image
    tag: from-develop-branch
    working_directory: './example_nodejs_postgres'
    stage: 'build phase'   
  mySecondDockerImage:
    title: 'Building Microservice B'
    type: build
    dockerfile: Dockerfile
    working_directory: './trivial-go-web'
    image_name: my-app-image
    tag: from-master-branch
    stage: 'build phase'

The pipeline first checks out two different Git repositories (which themselves contain Dockerfiles). Then it creates a Docker image for each one using the respective Dockerfile.

You can see both images in the Docker image dashboard .

Notice that there are no explicit push steps in the pipeline, as all successful Codefresh pipelines automatically push to the private Docker registry.
