Migration tool for Botkube Cloud

Command line tool that helps you migrate your Botkube installation to Botkube Cloud.

Installation

go build -o bctl main.go

Usage

We assume you have a working Botkube instance and a Botkube Cloud account. This tool gathers all the information needed to migrate your Botkube instance from your Kubernetes cluster - a working kube config is also needed.

1. Find the namespace where the Botkube instance is installed (botkube is the default):

kubectl get ns
kubectl get pod -n botkube --show-labels

2. Login to Botkube Cloud:

bctl login

3. Run the migration tool and follow instructions:

bctl migrate --namespace botkube --labels app=botkube

Implementation details

Login

We tried to make the migration process as simple and automated as possible. The login workflow involves a locally served http server that listens for a callback from the browser after the user login. The callback contains the access token that is used to authenticate the user and is stored locally in ~/.botkube/config.json. The server is stopped after the callback is received.

Migration

Once user is logged in, Botkube CLI creates a Pod in the same namespace where Botkube resides. Then, it mounts the same Secrets and ConfigMaps as the Botkube Pod, and pulls entire configuration to a ConfigMap botkube-config-exporter.

Once we have the configuration, we can turn it into a API call and create identical resources in Botkube Cloud.
