Flux

The Botkube Flux executor plugin allows you to run the flux CLI commands directly within the chat window of your chosen communication platform.

The Flux plugin is hosted in the official Botkube plugin repository. To enable the Flux plugin, ensure that the botkube repository is defined under plugins in the values.yaml file.

botkube:
url: https://github.com/kubeshop/botkube/releases/download/v1.6.0/plugins-index.yaml

Prerequisite elevated RBAC permissions​

One of the plugin capabilities is the flux diff command. To use it, you need to update the Flux plugin RBAC configuration. This is necessary because the command performs a server-side dry run that requires patch permissions, as specified in the Kubernetes documentation.

If you use Botkube self-hosted installation in version 1.4.1 or newer, you can create them during Botkube install/upgrade by specifying --set="rbac.groups.flux.create=true" override.

However, you can also create them manually:

cat > /tmp/flux-rbac.yaml << ENDOFFILE
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
name: flux
rules:
- apiGroups: ["*"]
resources: ["*"]
verbs: ["get", "watch", "list", "patch"]
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
name: flux
roleRef:
apiGroup: rbac.authorization.k8s.io
kind: ClusterRole
name: flux
subjects:
- kind: Group
name: flux
apiGroup: rbac.authorization.k8s.io
ENDOFFILE

kubectl apply -f /tmp/flux-rbac.yaml

Next, use the flux group in the plugin RBAC configuration:

executors:
flux:
botkube/flux:
enabled: true
config:
# ...

context:
rbac:
group:
type: Static
static:
values: ["flux"]

Enabling plugin​

To enable the GitHub plugin, add the following flag to the Botkube install command:

--set 'executors.flux.botkube/flux.enabled'=true

The Flux plugin comes with integrated GitHub support. To enable it, you'll need a valid GitHub token. Set the token using the following command:

--set 'executors.flux.botkube/flux.config.github.auth.accessToken=<GitHub token>'

By default, the Flux plugin has read-only access. To perform actions like creating or deleting Flux-related sources, you'll need to customize the RBAC.
