No Dockerfile found

Failed to fetch the Dockerfile from path

Issue

Build step in your pipeline fails with the error message:

Repository does not contain a Dockerfile. Please check the pipeline configuration

OR

Failed to fetch the Dockerfile from path

Possible cause

This issue occurs when you are trying to build a Docker image and the pipeline step cannot find a Dockerfile. It might be helpful to include a dummy step in your pipeline that prints all files in the workspace. This way you can verify what files are available to the pipeline.

pipeline step

print_pwd_files:
  title: 'Listing files'
  image: alpine:latest
  commands:
    - 'ls -l'

Solution

There are two ways to address this error:

Include clone step with name main_clone

First, make sure that you have at least one clone step in your pipeline, main_clone as the name. This way the current folder is automatically set up in the project folder of the Git repository.

codefresh.yml

version: '1.0'
steps:
  main_clone:
    title: 'Cloning main repository...'
    type: git-clone
    repo: kostis-codefresh/example_nodejs_postgres
    revision: master
    git: github
  myDockerImage:
    title: 'Building My Docker Image'
    type: build
    dockerfile: Dockerfile
    image_name: my-app-image
    tag: from-master-branch

Verify target directory of build step

Secondly, if you check out multiple Git repositories or use a different name in your Git clone step, make sure that the build step looks at the correct directory:

codefresh.yml

version: '1.0'
steps:
  checkoutApp:
    title: 'Cloning a repository...'
    type: git-clone
    repo: kostis-codefresh/trivial-go-web
    revision: master
    git: github
  myDockerImage:
    title: 'Building Docker Image'
    type: build
    dockerfile: Dockerfile
    working_directory: './trivial-go-web'
    image_name: my-app-image
    tag: from-master-branch

Notice that the working_directory property of the build step, searches for the Dockefile in the folder named trivial-go-web instead of the root folder of the pipeline workspace.
