Installing the CLI

General prerequisites

Before you install the DC/OS CLI, ensure the following:

  • You have a separate computer that is not part of the DC/OS cluster on which you can install the CLI.
  • You must have network access from the external system hosting the CLI to the DC/OS cluster.
  • You can open a command-line shell terminal on the external system hosting the CLI.
  • You are not using noexec to mount the /tmp directory. Mounting the /tmp directory with the noexec option can prevent CLI operations.

The recommended method to install the DC/OS CLI is from the DC/OS web interface. Or, you can manually install the CLI by using the following instructions.

Installing CLI from the web interface

  1. Click Install CLI from the top-left corner of the DC/OS web interface.

    CLI install UI

  2. Copy and paste the code snippets into your terminal.

    CLI copy/paste

Manually installing the CLI

Installing on Linux

Prerequisites

  • You must have a separate computer that is not part of the DC/OS cluster on which you can install the CLI.
  • You must have network access from the external system hosting the CLI to the DC/OS cluster.
  • You must be able to open a command-line shell terminal on the external system hosting the CLI.
  • You nust be able to run cURL program on the system hosting the CLI. The curl command is installed by default on most Linux distributions.
  • You must not be using noexec to mount the /tmp directory. Mounting the /tmp directory with the noexec option can prevent CLI operations.

Installing the DC/OS CLI

  1. If you do not already have a working directory for the CLI, create one. The preferred location is /usr/local/bin and all the instructions will reference this path.

    [ -d usr/local/bin ] || sudo mkdir -p /usr/local/bin

  2. Download the DC/OS CLI binary (dcos) to your local directory (for example, /usr/local/bin/).

    curl https://downloads.dcos.io/binaries/cli/linux/x86-64/dcos-1.10/dcos -o dcos

  3. Move the CLI binary to your local bin directory.

    sudo mv dcos /usr/local/bin

  4. Make the CLI binary executable.

    chmod +x /usr/local/bin/dcos

  5. Set up the connection from the CLI to your DC/OS cluster. In this example, http://example.com is the master node URL.

    dcos cluster setup http://example.com

    Follow the instructions in the DC/OS CLI. For more information about security, see the documentation.

    Your CLI should now be authenticated with your cluster!

Installing on macOS

Prerequisites

  • You must have a separate computer that is not part of the DC/OS cluster on which you can install the CLI.
  • You must have network access from the external system hosting the CLI to the DC/OS cluster.
  • You must be able to open a command-line environment, such as Terminal, on the external system hosting the CLI.
  • You nust be able to run cURL program on the system hosting the CLI. If you don’t have cURL, follow the instructions in Install curl on Mac OSX to install it.
  • You must not be using noexec to mount the /tmp directory. Mounting the /tmp directory with the noexec option can prevent CLI operations.

  2. Download the DC/OS CLI binary (dcos) to your local directory (for example, /usr/local/bin/).

    curl https://downloads.dcos.io/binaries/cli/darwin/x86-64/dcos-1.10/dcos -o dcos

  3. Move the CLI binary to your local bin directory.

    sudo mv dcos /usr/local/bin

  4. Make the CLI binary executable.

    chmod +x dcos

  5. Set up the connection from the CLI to your DC/OS cluster. In this example, http://example.com is the master node URL.

    dcos cluster setup http://example.com

    If your system is unable to find the executable, you may need to re-open the command prompt or add the installation directory to your PATH environment variable manually.

    Follow the instructions in the DC/OS CLI. For more information about security, see Security.

    Your CLI should now be authenticated with your cluster.

Installing on Windows

Prerequisites

  • You must have a separate computer that is not part of the DC/OS cluster on which you can install the CLI.
  • You must have network access from the external system hosting the CLI to the DC/OS cluster.
  • You must be able to open a command-line environment, such as Windows PowerShell or the cmd.exe program, on the external system hosting the CLI. Windows PowerShell is installed by default on Windows 7 and later.
  • You nust disable any security or antivirus software before you start the installation.
  • You must not be using noexec to mount the /tmp directory. Mounting the /tmp directory with the noexec option can prevent CLI operations.

  1. Open the command-line environment using the Administrator credentials.

  2. Download the DC/OS CLI executable to your local directory (dcos.exe).

  3. Change into the directory of the downloaded file if you are not already there.

    cd path/to/download/directory

  4. Set up the connection from the CLI to your DC/OS cluster. In this example, http://example.com is the master node URL.

    dcos cluster setup http://example.com

    Follow the instructions in the DC/OS CLI. For more information about security, see Security.
