The DC/OS command line interface (DC/OS CLI) utility allows you to manage clusters, and manage services and tasks.
DC/OS CLI versions and configuration files
Different CLI versions are compatible with different versions of DC/OS. To determine which combinations are supported, see the CLI support matrix.
DC/OS CLI 0.4.x and 0.5.x use a different structure for the location of configuration files.
DC/OS CLI 0.4.x has a single configuration file, which by default is stored in
~/.dcos/dcos.toml. In DC/OS CLI 0.4.x you can optionally change the location of the configuration file using the
DCOS_CONFIG environment variable.
DC/OS CLI 0.5.x has a configuration file for each connected cluster, which by default is stored in
~/.dcos/clusters/<cluster_id>/dcos.toml. In DC/OS CLI 0.5.x you can optionally change the base portion (
~/.dcos) of the configuration directory using the
DCOS_DIR environment variable.
- If you update to the DC/OS CLI 0.5.x and run any CLI command, it will trigger conversion from the old to the new configuration structure.
- After you call
dcos cluster setup, (or after conversion has occurred), if you attempt to update the cluster configuration using a
dcos config setcommand, the command displays a warning message saying the command is deprecated and the cluster configuration state may now be corrupted.
Latest version install
DC/OS 1.13 requires DC/OS CLI >= 0.8. To install it, follow these instructions.
To list available commands in the DC/OS CLI, run
dcos with no parameters:
$ dcos Usage: dcos [command] Commands: auth Authenticate to DC/OS cluster cluster Manage your DC/OS clusters config Manage the DC/OS configuration file help Help about any command job Deploy and manage jobs in DC/OS marathon Deploy and manage applications to DC/OS node View DC/OS node information package Install and manage DC/OS software packages plugin Manage CLI plugins service Manage DC/OS services task Manage DC/OS tasks Options: --version Print version information -v, -vv Output verbosity (verbose or very verbose) -h, --help Show usage help Use "dcos [command] --help" for more information about a command.
The following commands are available only in the Enterprise version of the CLI:
For instructions on installing the DC/OS Enterprise version of the CLI, see the documentation.
Setting up a cluster
In order to interact with your cluster, you first need to set up the CLI.
To display the DC/OS CLI version, run:
The DC/OS CLI supports the following environment variables, which can be set dynamically.
DCOS_CLUSTER (DC/OS CLI 0.5.x and later only)
The attached cluster. To set the attached cluster, set the variable with the command:
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
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.
DCOS_CONFIG (DC/OS CLI 0.4.x only)
This command displays the path to a DC/OS configuration file. If you put the DC/OS configuration file in
/home/jdoe/config/dcos.toml, set the variable with the command:
If you have the
DCOS_CONFIG environment variable configured:
- After conversion to the new configuration structure,
DCOS_CONFIGis no longer honored.
- Before you call
dcos cluster setup, you can change the configuration pointed to by
dcos config set. This command displays a warning message saying the command is deprecated and recommends using
dcos cluster setup.
Listing your clusters
The DC/OS CLI can work with multiple clusters. The following command displays the latest configured cluster:
DCOS_DIR (DC/OS CLI 0.5.x and later only)
If you want to set the DC/OS configuration directory to a specific path, such as
/home/jdoe/config, set the variable with the command:
DCOS_DIR and run
dcos cluster setup command.
``` export DCOS_DIR=<path/to/config_dir> (optional, default when not set is ~/.dcos) dcos cluster setup <url> ```
This setting generates and updates per cluster configuration under
$DCOS_DIR/clusters/<cluster_id>. Sets newly set up cluster as the attached one.
This command indicates whether to verify SSL certificates or set the path to the SSL certificates. You must set this variable manually. Setting this environment variable is equivalent to setting the
dcos config set core.ssl_verify option in the DC/OS configuration file. For example, to indicate that you want to set the path to SSL certificates:
$ dcos cluster list NAME ID STATUS VERSION URL * cluster 26f72c2f-8d03-47d7-b95f-972b1fd3dea2 AVAILABLE 1.13 <cluster-url>
This command displays log messages to
stderr at or above the level indicated. This is equivalent to the
--log-level command-line option. The severity levels are:
- debug Prints all messages to
stderr, including informational, warning, error, and critical.
- info Prints informational, warning, error, and critical messages to
- warning Prints warning, error, and critical messages to
- error Prints error and critical messages to
- critical Prints only critical messages to
For example, to set the log level to warning:
This command indicates whether to print additional debug messages to
stdout. By default this is set to
false. For example:
