k8s-mattermost

What is it ?

k8s-mattermost is a bot that connects to a Mattermost channel's websocket and watches for kubectl commands.

By default, you can trigger the bot with !k <namespace> <verb> <ressource> :

!k - get cs  # You can use "-" if ressource doesn't get namespace

!k kube-system get deploy

!k all get pod # You can use "all" to show all namespaces

The configuration is located in the config.toml.dist file (you should rename it to config.toml) :

[general]
bot_name = "k8s-bot"
kubectl_path = "/usr/local/bin/kubectl"

[mattermost]
host = "your-mattermost.org"
channel_name = "kubernetes"
team_name = "your-team"
user_login = "bot@email.org"
user_password = "averystr0ngpassw0rd"

You can load a different config file using the -c flag.

How can you run it ?
