Exec

The exec executor plugin allows you to install and run CLI applications directly from chat (e.g., Slack, Discord, or Mattermost) without any hassle.

The exec plugin is hosted by the official Botkube plugin repository. To enable the exec plugin, make sure that the botkube repository is defined under plugins in the values.yaml file.

plugins:
  repositories:
    botkube:
      url: https://github.com/kubeshop/botkube/releases/download/v1.3.0/plugins-index.yaml

Enabling plugin

To enable exec plugin, add --set 'executors.bins-management.botkube/exec.enabled=true' to a given Botkube install command. By default, the read-only KUBECONFIG is assigned.

For enabling commands that require create, update or delete rules, you need to create specific (Cluster)Role and (Cluster)RoleBinding and reference it from plugin's context configuration. To learn more refer to the RBAC section.
