Executor

The executor configuration allows you to define multiple executor configurations that can be later referred in communication bindings. For example, take a look at such executor definition:

executors:
  "kubectl-global": # This is an executor configuration name, which is referred in communication bindings.
    kubectl:
      # ... trimmed ...

  "helm-read-only": # This is an executor configuration name, which is referred in communication bindings.
    helm:
      # ... trimmed ...

This can be later used by the communication platforms:

communications:
  "default-group":
    slack:
      channels:
        "default":
          bindings:
            executors: # The order is important for merging strategy.
              - kubectl-global # The executor configuration name
              - helm-read-only # The executor configuration name
          # ... trimmed ...

To use the Botkube executor plugins, first you need to define the plugins repository under the plugins property:

plugins:
  repositories:
    repo-name:
      url: https://example.com/plugins-index.yaml

Next, you can configure executor from a given repository:

executors:
  "plugin-based":
    repo-name/executor-name@v1.0.0: # Plugin name syntax: <repo>/<plugin>[@<version>]. If version is not provided, the latest version from repository is used.
      enabled: true
      config: {}

For all executor configuration properties, see the syntax section.

Syntax

# Map of executors. The `executors` property name is an alias for a given configuration.
# Key name is used as a binding reference.
#
# Format: executors.{alias}
executors:
  "plugin-based":
    botkube/helm@v1.0.1: # Plugin name syntax: <repo>/<plugin>[@<version>]. If version is not provided, the latest version from repository is used.
      enabled: true # If not enabled, plugin is not downloaded and started.
      config: # Plugin's specific configuration.
        helmDriver: "secret"

  "kubectl-read-only":
    # Built-in kubectl executor configuration.
    kubectl:
      enabled: true
      # Kubectl configuration
      namespaces:
        include:
          - ".*"
      # ... trimmed ...

# Configuration for Botkube executors and sources plugins.
plugins:
  # Directory, where downloaded plugins are cached.
  cacheDir: "/tmp"
  # List of plugins repositories.
  repositories:
    # This repository serves officially supported Botkube plugins.
    botkube:
      url: https://github.com/kubeshop/botkube/releases/download/v0.18.0/plugins-index.yaml
    # Other 3rd party repositories.
    repo-name:
      url: https://example.com/plugins-index.yaml

The default configuration for the Botkube Helm chart can be found in the values.yaml file.
