Multiple Hosts

You can configure the UI to have multiple ClickHouse hosts by using these environment variables:

  • CLICKHOUSE_HOST: Separated by commas, for example: http://ch-1:8123,http://ch-2:8123
  • CLICKHOUSE_NAME: (Optional) Name of the ClickHouse instance, must match the number of hosts in CLICKHOUSE_HOST, for example ch-1,ch-2.

All these hosts will share the same CLICKHOUSE_USER and CLICKHOUSE_PASSWORD. If you want to have multiple users/passwords for each host, specify them in the usual way:

  • CLICKHOUSE_USER: user1,user2
  • CLICKHOUSE_PASSWORD: password1,password2

Examples Docker

docker run -it \
  -e CLICKHOUSE_HOST='http://ch-1:8123,http://ch-2:8123' \
  -e CLICKHOUSE_NAME='ch-1,ch-2' \
  -e CLICKHOUSE_USER='default' \
  -e CLICKHOUSE_PASSWORD='' \
  --name clickhouse-monitoring \
ghcr.io/duyet/clickhouse-monitoring:main

Examples Kubernetes

helm repo add duyet https://duyet.github.io/charts
 
cat <<EOF >> values.yaml
env:
- name: CLICKHOUSE_HOST
  value: http://ch-1:8123,http://ch-2:8123
