Deis Control Utility

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

Installation

Latest deisctl

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

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

The installer puts deisctl in your current directory and downloads current Deis unit files to $HOME/.deis/units one time. You should move deisctl somewhere in your $PATH.

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.

Builds for a specific Deis release

Note that this script will always give you the most freshly-built deisctl off master. If you are using a specific Deis release (not latest), you'll want to use the deisctl built for your release.

Builds are hosted on an S3 bucket at this URL format: https://s3-us-west-2.amazonaws.com/opdemand/deisctl-<VERSION>-<darwin|linux>-amd64.run

The deisctl release for Deis version 0.13 can be downloaded here: Mac OS X | Linux

Building from source

If you want to install from source, ensure you have https://github.com/tools/godep installed, 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"

This is also useful for specifying custom behavior on Deis units, such as using fleet metadata to lock the builder to a more powerful node, or keep application nodes free of control plane elements.

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 core@172.17.8.100 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.

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:

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

Unit Search Paths

deisctl looks for unit files in these directories, in this order:

  • the $DEISCTL_UNITS environment variable, if set
  • $HOME/.deis/units
  • /var/lib/deis/units
