Slack

Install BotKube to the Slack workspace

Follow the steps below to install BotKube Slack app to your Slack workspace.

Install BotKube Slack app to your Slack workspace

Click the Add to Slack button provided to install BotKube Slack application to your workspace. Once you have authorized the application, you will be provided a BOT Access token. Kindly note down that token as it will be required while deploying BotKube backend to your Kubernetes cluster.

Alternatively, you can install BotKube Slack app from Slack app directory.

Add BotKube user to a Slack channel

After installing BotKube app to your Slack workspace, you could see a new bot user with the name “BotKube” added in your workspace. Add that bot to a Slack channel you want to receive notification in. (You can add it by inviting @BotKube in a channel)

Install BotKube Backend in Kubernetes cluster

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.slack.enabled=true \
  --set communications.slack.channel=<SLACK_CHANNEL_NAME> \
  --set communications.slack.token=<SLACK_API_TOKEN_FOR_THE_BOT> \
  --set config.settings.clustername=<CLUSTER_NAME> \
  --set config.settings.kubectl.enabled=<ALLOW_KUBECTL> \
  --set image.tag=v0.12.4 \
  botkube/botkube
  

  where,

  • SLACK_CHANNEL_NAME is the channel name where @BotKube is added
  • SLACK_API_TOKEN_FOR_THE_BOT is the Token you received after installing BotKube app to your Slack workspace
  • CLUSTER_NAME is the cluster name set in the incoming messages
  • ALLOW_KUBECTL set true to allow kubectl command execution by BotKube on the cluster

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

  Send @BotKube ping in the channel to see if BotKube is running and responding.

  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:

  • Create new file config.yaml and add resource configuration as described on the configuration page.

    (You can refer sample config from https://raw.githubusercontent.com/kubeshop/botkube/v0.12.4/helm/botkube/sample-res-config.yaml)

  config:
    ## Resources you want to watch
    resources:
    - name: v1/pods        # Name of the resource. Resource name must be in
                           # group/version/resource (G/V/R) format
                           # resource name should be plural
                           # (e.g apps/v1/deployments, v1/pods)
      namespaces:          # List of namespaces, "all" will watch all the namespaces
        include:
        - all
        ignore:            # List of namespaces to be ignored, used only with include: all
        - kube-system      # example : include [all], ignore [x,y,z]
      events:              # List of lifecycle events you want to receive,
                           # e.g create, update, delete, error OR all
      - create
      - delete
      - error
    - name: batch/v1/jobs
      namespaces:
        include:
        - ns1
        - ns2
      events:
      - create
      - update
      - delete
      - error
      updateSetting:
        includeDiff: true
        fields:
        - spec.template.spec.containers[*].image
        - status.conditions[*].type
  

  • 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 from Slack workspace
