Deis Control Utility

deisctl is a command-line utility used to provision and operate a Deis cluster.

Installation

To install deisctl on Linux or Mac OS X, run this command:

$ curl -sSL http://deis.io/deisctl/install.sh | sudo sh

The installer puts deisctl in /usr/local/bin and downloads current Deis unit files to /var/lib/deis/units one time.

To change installation options, save the installer directly from one of these links:

Download for Linux Download for Mac OS X

Then run the downloaded file as a shell script. Append --help to see what options are available.

If you want to install from source, clone the repository and run

$ godep get .

Then, export the DEISCTL_UNITS environment variable so deisctl can find the units:

$ export DEISCTL_UNITS="$PATH_TO_DEISCTL/units"

Remote Configuration

While deisctl can be used locally on a CoreOS host, it is extremely useful as a tool for remote administration. This requires an SSH tunnel to one of your CoreOS hosts.

Test password-less SSH connectivity to a CoreOS host:

$ ssh [email protected] hostname
deis-1

Export the DEISCTL_TUNNEL environment variable:

$ export DEISCTL_TUNNEL=172.17.8.100

Provision a Deis Platform

The deisctl install platform command will schedule all of the Deis platform units. deisctl start platform activates these units.

$ deisctl install platform

Deis started.

Note that the default start command activates 1 of each component. You can scale components with deisctl scale router=3, for example. The router is the only component that currently scales beyond 1 unit.

You can also use the deisctl uninstall command to destroy platform units:

$ deisctl uninstall platform

Done.

To uninstall a specific component, use deisctl uninstall router.

Note that uninstalling platform units will not remove the data units or underlying data containers. Data must be destroyed manually.

Usage

The deisctl tool provides a number of other commands, including:

  • deisctl list - list Deis platform components
  • deisctl status <component> - retrieve Systemd status of a component
  • deisctl journal <component> - retrieve Systemd journal output
  • deisctl start <component> - start a platform component
  • deisctl stop <component> - stop a platform component
  • deisctl install <component> - install a single platform component
  • deisctl uninstall <component> - uninstall a single platform component
  • deisctl scale <component>=<num> - scale a component to the target number of units
  • deisctl refresh-units - download latest unit files
