# Deis Control Utility

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

## Installation

Please refer to the installation docs at
http://docs.deis.io/en/latest/installing_deis/install-deisctl/.

## 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:

```console
$ ssh core@172.17.8.100 hostname
deis-1
```

Export the `DEISCTL_TUNNEL` environment variable:

```console
$ 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.

```console
$ deisctl install platform
● ▴ ■
■ ● ▴ Installing Deis...
▴ ■ ●

Logging subsystem...
deis-logger.service: loaded
Storage subsystem...
deis-store-gateway@1.service: loaded

deis-database.service: loaded
deis-registry@1.service: loaded

deis-router@1.service: loaded
deis-router@2.service: loaded
deis-router@3.service: loaded
Done.
Deis installed.
Please run `deisctl start platform` to boot up Deis.

$ deisctl start platform
● ▴ ■
■ ● ▴ Starting Deis...
▴ ■ ●

Logging subsystem...
deis-logger.service: running
deis-logspout.service: running
Storage subsystem...
deis-store-daemon.service: running
deis-store-monitor.service: running
deis-store-gateway@1.service: running

deis-database.service: running
deis-registry@1.service: running

Data plane...
deis-publisher.service: running
Routing mesh...
deis-router@1.service: running
deis-router@2.service: running
deis-router@3.service: running
Done.
```

Note that the default start command activates 1 of each component.
You can scale components with `deisctl scale router=3`, for example.
The router, the registry and the store gateway are the only component that _currently_ scales beyond 1 unit.

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

```console
● ▴ ■
■ ● ▴ Uninstalling Deis...
▴ ■ ●

Routing mesh...
deis-router@1.service: inactive
deis-router@2.service: inactive
deis-router@3.service: inactive
Data plane...
Control plane...
deis-controller.service: inactive
deis-builder.service: inactive
deis-database.service: inactive
deis-registry@1.service: inactive
Storage subsystem...
deis-store-gateway@1.service: inactive
Logging subsystem...
deis-logger.service: inactive
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

## Usage Examples

```console
$ deisctl list
UNIT				MACHINE				LOAD	ACTIVE	SUB
deis-builder.service		f936b7a5.../172.17.8.100	loaded	active	running
deis-controller.service	    f936b7a5.../172.17.8.100	loaded	active	running
deis-database.service		f936b7a5.../172.17.8.100	loaded	active	running
deis-logger.service	    	f936b7a5.../172.17.8.100	loaded	active	running
deis-registry@1.service		f936b7a5.../172.17.8.100	loaded	active	running
deis-router@1.service		f936b7a5.../172.17.8.100	loaded	active	running
```

## 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
