Installing DCOS CLI for Mesos

To install the DCOS CLI:

Install virtualenv. The Python tool virtualenv is used to manage the DCOS CLI’s environment.

$ sudo pip install virtualenv

Tip: On some older Python versions, ignore any ‘Insecure Platform’ warnings. For more information, see

From the command line, create a new directory named dcos and navigate into it.

$ mkdir dcos
$ cd dcos
$ curl -O

Run the DCOS CLI install script, where <hosturl> is the hostname of your master node prefixed with http://:

$ bash <install_dir> <mesos-master-host>

For example, if the hostname of your mesos master node is

$ bash .

Follow the on-screen DCOS CLI instructions and enter the Mesosphere verification code. You can ignore any Python ‘Insecure Platform’ warnings.

Confirm whether you want to add DCOS to your system PATH:

$ Modify your bash profile to add DCOS to your PATH? [yes/no]

Since DCOS CLI is used for DCOS cluster, need to reconfigure Marathon and Mesos masters urls with the following commands:

dcos config set core.mesos_master_url http://<mesos-master-host>:5050
dcos config set marathon.url http://<marathon-host>:8080
