# Setup Earthly - GitHub Action
This repository contains an action for use with GitHub Actions, which installs [earthly](https://github.com/earthly/earthly) with a semver-compatible version.
The package is installed into `/home/runner/.earthly` (or equivalent on Windows) and the `bin` subdirectory is added to the PATH.
## Usage
Full example:
```yml
name: GitHub Actions CI
on:
push:
branches: [main]
pull_request:
branches: [main]
jobs:
tests:
name: example earthly test
runs-on: ubuntu-latest
steps:
- uses: earthly/actions-setup@v1
with:
github-token: ${{ secrets.GITHUB_TOKEN }}
version: "latest" # or pin to an specific version, e.g. "0.8.1"
- uses: actions/checkout@v2
- name: Docker login # to avoid dockerhub rate-limiting
run: docker login --username "${{ secrets.DOCKERHUB_USERNAME }}" --password "${{ secrets.DOCKERHUB_PASSWORD }}"
- name: what version is installed?
run: earthly --version
- name: run the earthly hello world
run: earthly github.com/earthly/hello-world:main+hello
```
Install the latest version of earthly:
```yaml
- name: Install earthly
uses: earthly/actions-setup@v1
with:
github-token: ${{ secrets.GITHUB_TOKEN }}
```
Install a specific version of earthly:
```yaml
- name: Install earthly
uses: earthly/actions-setup@v1
with:
github-token: ${{ secrets.GITHUB_TOKEN }}
version: 0.8.1
```
Install a version that adheres to a semver range
```yaml
- name: Install earthly
uses: earthly/actions-setup@v1
with:
github-token: ${{ secrets.GITHUB_TOKEN }}
version: ^0.8.0
```
### Testing
You can perform a local test by running `earthly +all`.
It is also possible to use [act](https://github.com/nektos/act) to test the contents of the github actions config.
## Configuration
The action can be configured with the following arguments:
- `version` - The version of earthly to install. Default is `latest`. Accepts semver style values.
- `prerelease` (optional) - allow prerelease versions.
- `use-cache` (optional) - whether to use the cache to store earthly or not.
- `github-token` (optional) - GitHub token for fetching earthly version list. Recommended to avoid GitHub API ratelimit.
