Communication

The communication settings contain:

• Configuration for communication platforms scoped in separate communication groups,
• Platform-specific options, such as multichannel configuration for platforms that support channels.

Communication groups

Communication group is a way to aggregate separate configurations for a set of communication platforms. You can specify multiple communication groups, and, in a result, support multiple Slack or Mattermost workspaces, Discord servers, or Elasticsearch server instances.

Also, most platforms also support another level of multiple configurations within a workspace. For example, Slack supports multichannel configuration. To learn more about platform-specific options, see the Syntax section.

note

The purpose of the communication group is to allow using multiple workspaces, e.g. for Slack or Mattermost. To use multiple channels inside the same workspace, don't define separate communication groups, but use channels property under a given communication platform instead.

Example

Consider the following configuration:

communications:
  "first-group": # Your own alias of a given communication group
    socketSlack:
      enabled: true
      botToken: "{SLACK_BOT_TOKEN_1}" # Bot token for Botkube App for Slack installed in Workspace 1
      appToken: "{SLACK_APP_TOKEN_1}" # App token for Botkube App for Slack installed in Workspace 1
      channels:
        "general": # Your own alias for the channel configuration
          name: general
          bindings:
            executors: # Executors configuration for a given channel
              - k8s-default-tools
            sources: # Notification sources configuration for a given channel
              - k8s-events
        "random": # Your own alias for the channel configuration
          name: random
          bindings:
            executors: [] # Executors configuration for a given channel
            sources: # Notification sources configuration for a given channel
              - k8s-events
  "second-group": # Your own alias of a given communication group
    socketSlack:
      enabled: true
      botToken: "{SLACK_BOT_TOKEN_2}" # Bot token for Botkube App for Slack installed in Workspace 2
      appToken: "{SLACK_APP_TOKEN_2}" # App token for Botkube App for Slack installed in Workspace 2
      channels:
        "primary-channel": # Your own alias for the channel configuration
          name: general
          notification:
            # If true, the notifications are not sent to the channel. They can be enabled with `@Botkube` command anytime.
            disabled: true
          bindings:
            executors: # Executors configuration for a given channel
              - k8s-default-tools
            sources: # Notification sources configuration for a given channel
              - k8s-events

The example YAML configuration definition results in the following configuration.

For Slack Workspace 1, as defined by the first communication group (first-group):

• Notifications from k8s-events source are sent to the general and random channels.
• Commands from the k8s-default-tools configuration can be executed in the general channel. On random channel executors are not configured.

For Slack Workspace 2, as defined by the second communication group (second-group):

• Notifications are configured to be sent from the k8s-events source to the general channel. They are disabled by default, and can be enabled with @Botkube command or during Botkube upgrade.
• Commands from the k8s-default-tools configuration can be executed in the general channel.

Source and Executor Bindings

Most of the communication platforms support executor and source bindings, which allows fine-tuning the notifications and allowed Botkube commands inside a given channel.

With executor bindings you can configure which executors are allowed in a given channel. To read more about executor configuration, see the Executor document.

With source bindings, you can specify which events are sent to a given channel (or, in case of Elasticsearch, index). To read more about source configuration, see the Source document.

Syntax

Each communication platform has specific options, however they share a similar syntax for consistency. For example, bot integrations such as Slack, Mattermost or Discord have multichannel support, that is you can configure multiple channels with separate bindings. Same with Elasticsearch - you can forward notifications to multiple Elasticsearch indices, according to the sources configuration.
