The Ark client provides a CLI that allows you to initiate ad-hoc backups, scheduled backups, or restores.
*The files in this directory enumerate each of the possible `ark` commands and their flags. Note that you can also find this info with the CLI itself, using the `--help` flag.*
[The files in the CLI reference directory][1] in the repository enumerate each of the possible `ark` commands and their flags.
This information is available in the CLI, using the `--help` flag.
## Running the client
While it is possible to build and run the `ark` executable yourself, it is recommended to use the containerized version. Use the alias described in the quickstart:
```
alias ark='docker run --rm -u $(id -u) -v $(dirname $KUBECONFIG):/kubeconfig -e KUBECONFIG=/kubeconfig/$(basename $KUBECONFIG) gcr.io/heptio-images/ark:latest'
```
Assuming that your `KUBECONFIG` variable is set, this alias takes care of specifying the appropriate Kubernetes cluster credentials for you.
We recommend that you [download a pre-built release][26], but you can also build and run the `ark` executable.
## Kubernetes cluster credentials
In general, Ark will search for your cluster credentials in the following order:
* `--kubeconfig` command line flag
* `$KUBECONFIG` environment variable
* In-cluster credentials--this only works when you are running Ark in a pod
