Install Botkube Backend in Kubernetes cluster​
- We use Helm to install Botkube in Kubernetes. Follow this guide to install helm if you don't have it installed already. 
- Add botkube chart repository: - helm repo add botkube https://charts.botkube.io
 helm repo update
- Deploy Botkube backend using helm install in your cluster: - export CLUSTER_NAME={cluster_name}
 export ELASTICSEARCH_ADDRESS={elasticsearch_address}
 export ELASTICSEARCH_USERNAME={elasticsearch_username}
 export ELASTICSEARCH_PASSWORD={elasticsearch_password}
 export ELASTICSEARCH_INDEX_NAME={elasticsearch_index_name}
 helm install --version v1.1.1 botkube --namespace botkube --create-namespace \
 --set communications.default-group.elasticsearch.enabled=true \
 --set communications.default-group.elasticsearch.server=${ELASTICSEARCH_ADDRESS} \
 --set communications.default-group.elasticsearch.username=${ELASTICSEARCH_USERNAME} \
 --set communications.default-group.elasticsearch.password=${ELASTICSEARCH_PASSWORD} \
 --set communications.default-group.elasticsearch.indices.default.name=${ELASTICSEARCH_INDEX_NAME} \
 --set settings.clusterName=${CLUSTER_NAME} \
 botkube/botkube- where: - ELASTICSEARCH_ADDRESS is an address on which ElasticSearch server is reachable e.g https://example.com:9243,
- ELASTICSEARCH_USERNAME is the username for authentication to Els server,
- ELASTICSEARCH_PASSWORD is a password for the username to authenticate with Els server,
- ELASTICSEARCH_INDEX_NAME (optional) is an index name on which Botkube events will be stored (default: botkube).
 - Configuration syntax is explained here. Full Helm chart parameters list is documented here. - With the default configuration, Botkube will watch all the resources in all the namespaces for create, delete and error events. - If you wish to monitor only specific resources, follow the steps given below: - Create a new - config.yamlfile and add Kubernetes resource configuration as described on the source page.
- Pass the YAML file as a flag to - helm installcommand, e.g.:- helm install --version v1.1.1 --name botkube --namespace botkube --create-namespace -f /path/to/config.yaml --set=...other args..
 - Alternatively, you can also update the configuration at runtime as documented here. 
Remove Botkube​
Execute following command to completely remove Botkube and related resources from your cluster:
helm uninstall botkube --namespace botkube
