# dockerhub-description
# 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"]
}
```
