Build an Image with the Dockerfile in Root Directory

Get started quickly with building Docker images

Building a Docker image is one of the basic operations in Codefresh pipelines.

The source code of the repository is located at https://github.com/codefreshdemo/cf-yml-example-build-dockerfile-inroot. Feel free to fork it if you want to follow along.

If you don’t already have a Codefresh account, you can easily create a free one from the sign-up page.

Building a Dockerfile from the root folder

By default docker uses the Dockerfile of the current folder if you run a single command like:

docker build . -t my-web-app

The same thing can also be achieved within a Codefresh pipeline:

codefresh.yml

version: '1.0'
steps:
  main_clone:
    title: Cloning main repository...
    type: git-clone
    repo: 'codefreshdemo/cf-yml-example-build-dockerfile-inroot'
    revision: 'master'
    git: github
  build_my_app:
    title: Building Node.Js Docker Image
    type: build
    image_name: my-app
    working_directory: '${{main_clone}}'
    tag: 'master'
    dockerfile: Dockerfile

This pipeline checks out the source code of the repository and then builds a dockerfile found at the root folder of the project.

Building a Docker image with a default Dockerfile

You could also change the Docker build context by editing the working_directory property. By default it is looking at the root folder of the project, but any subfolder path is also valid.
