Configuration Manager

This reference covers version: 1.2.6.

Configuration manager is a small application used to automatically configure Aerokube products.

1. Configuring Selenoid

This section describes supported ways of automatic Selenoid configuration.

To quickly configure and run Selenoid type:

$ ./cm selenoid start

Selenoid can be configured in two ways:

Using Docker containers.
Using standalone binaries - when Docker is not installed.

Which mode to use is detected automatically by trying to access Docker API. To view the list of available commands:

$ ./cm selenoid --help

To launch command:

$ ./cm selenoid <command> [args...]

Supported commands are:

Table 1. Commands to configure and run Selenoid
Command	Meaning
cleanup	Removes Selenoid traces
configure	Creates Selenoid configuration file (implies download)
download	Downloads Selenoid binary or container image
start	Starts Selenoid process or container (implies download and configure)
status	Shows actual configuration status (whether Selenoid is downloaded, configured or running)
stop	Stops Selenoid process or container
update	Updates Selenoid and configuration to latest version

To see supported flags for each command append --help:

$ ./cm selenoid start --help

1.1. Example Commands

download command downloads latest or specified Selenoid release as standalone binary or container image:
```
$ ./cm selenoid download [--version 1.2.1] [--force]
```
Does nothing when already downloaded. Use --force flag to download again.
configure command in addition to downloading Selenoid also downloads container images or webdriver binaries and generates configuration file:
```
$ ./cm selenoid configure [--browsers firefox,opera] [--last-versions 2] [--tmpfs 128]
```
Use --browsers to limit browsers to be configured, --tmpfs - to add Tmpfs support, --last-versions - to limit how many last browser versions to download. If you wish to download all available versions - specify --last-versions 0.
start command configures Selenoid and starts it:
```
$ ./cm selenoid start
```
By default Selenoid data is stored in ~/.aerokube/selenoid but you can specify another directory using --config-dir flag. To download images with VNC server (to see live browser screen) use --vnc flag:
```
$ ./cm selenoid start --vnc
```
To override Selenoid startup arguments sessions add --args flag:
```
$ ./cm selenoid start --args "-limit 10"
```
An alternative to downloading cm manually is using Docker container:
```
# docker run --rm -v /var/run/docker.sock:/var/run/docker.sock -v ${HOME}:/root -e OVERRIDE_HOME=${HOME} aerokube/cm:latest-release selenoid start
```

2. Starting Selenoid UI

This section describes supported ways of automatic Selenoid UI startup.

To quickly run Selenoid UI type:

$ ./cm selenoid-ui start

Selenoid UI configuration algorithm is similar to Selenoid one - it is started either in Docker container if you have Docker installed or as a standalone binary otherwise. Supported commands are:

Table 2. Commands to run Selenoid UI
Command	Meaning
cleanup	Removes Selenoid UI traces
download	Downloads Selenoid UI binary or container image
start	Starts Selenoid UI process or container (implies download)
status	Shows actual service status (whether Selenoid is downloaded or running)
stop	Stops Selenoid UI process or container
update	Updates Selenoid to latest version

To see supported flags for each command append --help:

$ ./cm selenoid start --help

2.1. Example Commands

These commands just repeat similar commands for Selenoid so we give no comments here:

$ ./cm selenoid-ui download [--version 1.2.1] [--force]
$ ./cm selenoid-ui start
$ ./cm selenoid-ui start --args "--period 100ms"
# docker run --rm -v /var/run/docker.sock:/var/run/docker.sock -v ${HOME}:/root aerokube/cm:latest-release selenoid-ui start

3. Contributing & Development

To build cm:

Install Golang
Setup $GOPATH properly
Install govendor: $ go get -u github.com/kardianos/govendor
Get cm source:
```
$ go get -d github.com/aerokube/cm
```
Go to project directory:
```
$ cd $GOPATH/src/github.com/aerokube/cm
```
Checkout dependencies:
```
$ govendor sync
```
Build source:
```
$ go build
```
Run cm:
```
$ ./cm --help
```

To build Docker container type:

$ GOOS=linux GOARCH=amd64 CGO_ENABLED=0 go build
$ docker build -t cm:latest .
