Outgoing Webhook

Install BotKube Backend in Kubernetes cluster

BotKube can be integrated with external apps via Webhooks. A webhook is essentially a POST request sent to a callback URL. So you can configure BotKube to send events on specified URL.

Using helm

• We will be using helm to install BotKube in Kubernetes. Follow this guide to install helm if you don’t have it installed already.

• Add botkube chart repository:

  $ helm repo add botkube https://charts.botkube.io
  $ helm repo update
  

• Deploy BotKube backend using helm install in your cluster:

  $ helm install --version v0.12.4 botkube --namespace botkube --create-namespace \
  --set communications.webhook.enabled=true \
  --set communications.webhook.url=<WEBHOOK_URL> \
  --set config.settings.clustername=<CLUSTER_NAME> \
  --set image.tag=v0.12.4 \
  botkube/botkube
  

  where,

  • WEBHOOK_URL is an outgoing webook URL to which BotKube will POST the events
  • CLUSTER_NAME is the cluster name set in the incoming messages

  Configuration syntax is explained here. Full Helm chart parameters list is documented here.

  With the default configuration, BotKube will watch all the resources in all the namespaces for create, delete and error events. If you wish to monitor only specific resources, follow the steps given below:

  1. Create a new config.yaml file and add Kubernetes resource configuration as described on the source page.

  2. Pass the YAML file as a flag to helm install command, e.g.:

     helm install --version v0.12.4 --name botkube --namespace botkube --create-namespace -f /path/to/config.yaml --set=...other args..
     

  Alternatively, you can also update the configuration at runtime as documented here

Remove BotKube

Using helm

If you have installed BotKube backend using helm, execute following command to completely remove BotKube and related resources from your cluster

$ helm uninstall botkube
