Docker Hub Description

A GitHub action to update a Docker Hub repository description from README.md.

This is useful if you docker push your images to Docker Hub. It provides an easy, automated way to keep your Docker Hub repository description in sync with your GitHub repository README.md file.

Usage

action "Update Docker Hub Repository Description" {
  uses = "peter-evans/dockerhub-description@1.0"
  secrets = ["DOCKERHUB_USERNAME", "DOCKERHUB_PASSWORD", "DOCKERHUB_REPOSITORY"]
}

Required secrets

DOCKERHUB_USERNAME - Docker Hub username
DOCKERHUB_PASSWORD - Docker Hub password
DOCKERHUB_REPOSITORY - The name of the Docker Hub repository to update. (This may also be an environment variable if not considered sensitive)

Optionally specifying the file path

The action assumes that there is a file called README.md located at the root of the repository. If this is not the case, the path can be overridden with an environment variable.

action "Update Docker Hub Repository Description" {
  uses = "peter-evans/dockerhub-description@1.0"
  secrets = ["DOCKERHUB_USERNAME", "DOCKERHUB_PASSWORD", "DOCKERHUB_REPOSITORY"]
  env = {
    README_FILEPATH = "./some-path/README.md"
  }
}

Examples

Updates the Docker Hub repository description whenever there is a git push to the master branch.

workflow "New workflow" {
  on = "push"
  resolves = ["Update Docker Hub Repository Description"]
}

action "Filter master branch" {
  uses = "actions/bin/filter@master"
  args = "branch master"
}

action "Update Docker Hub Repository Description" {
  needs = ["Filter master branch"]
  uses = "peter-evans/dockerhub-description@1.0"
  secrets = ["DOCKERHUB_USERNAME", "DOCKERHUB_PASSWORD", "DOCKERHUB_REPOSITORY"]
}

Updates the Docker Hub repository description whenever a new release is created.

workflow "New workflow" {
  on = "release"
  resolves = ["Update Docker Hub Repository Description"]
}

action "Update Docker Hub Repository Description" {
  uses = "peter-evans/dockerhub-description@1.0"
  secrets = ["DOCKERHUB_USERNAME", "DOCKERHUB_PASSWORD", "DOCKERHUB_REPOSITORY"]
}
