# Flux GitHub Action
To install the latest Flux CLI on Linux, macOS or Windows GitHub runners:
```yaml
steps:
- name: Setup Flux CLI
uses: fluxcd/flux2/action@main
with:
version: 'latest'
- name: Run Flux CLI
run: flux version --client
```
To install Flux plugins alongside the CLI:
```yaml
steps:
- name: Setup Flux CLI
uses: fluxcd/flux2/action@main
with:
plugins: |
mirror@0.0.1
- name: Run Flux plugin
run: flux mirror --help
```
Installing plugins requires a Flux version with plugin support (v2.9.0 or later).
The `plugins` input accepts one plugin per line in `<name>@<version|digest>`
format. The `plugin-dir` input is only used when `plugins` is set; when
plugins are installed, the action exports `FLUXCD_PLUGINS` for subsequent
steps.
The Flux GitHub Action can be used to automate various tasks in CI, such as:
- [Automate Flux upgrades on clusters via Pull Requests](https://fluxcd.io/flux/flux-gh-action/#automate-flux-updates)
- [Push Kubernetes manifests to container registries](https://fluxcd.io/flux/flux-gh-action/#push-kubernetes-manifests-to-container-registries)
- [Run end-to-end testing with Flux and Kubernetes Kind](https://fluxcd.io/flux/flux-gh-action/#end-to-end-testing)
For more information, please see the [Flux GitHub Action documentation](https://fluxcd.io/flux/flux-gh-action/).
