The DC/OS command line interface (DC/OS CLI) utility allows you to manage cluster nodes, install and manage packages, inspect the cluster state, and manage services and tasks.

DC/OS 2.0 requires the DC/OS CLI >= 0.8. To install it, follow these instructions.

Setting up a cluster

In order to interact with your cluster, you first need to set up the CLI.

dcos cluster setup <cluster-url>

After following the login procedure, your CLI is now ready to interact with your cluster. You will notice that it now has additional commands such as marathon, node, package etc. These commands come from the plugins, dcos-core-cli and, if applicable, dcos-enterprise-cli, which is automatically installed as part of the setup command.

To display the DC/OS CLI version, run:

dcos --version

Listing your clusters

The DC/OS CLI can work with multiple clusters. The following command displays the latest configured cluster:

$ dcos cluster list
        NAME               ID                        STATUS     VERSION      URL
  *   cluster 26f72c2f-8d03-47d7-b95f-972b1fd3dea2  AVAILABLE    1.13  <cluster-url>

NOTE: The * indicates that the CLI is currently attached to the cluster name. If you run the setup command again with another cluster, you will see a new item in the list.

DC/OS CLI versions and configuration files

The DC/OS CLI has a configuration file for each connected cluster, which by default is stored in ~/.dcos/clusters/<cluster_id>/dcos.toml. You can optionally change the base portion (~/.dcos) of the configuration directory using the DCOS_DIR environment variable.
