ClickHouse database

The GitLab chart can be configured to set up GitLab with an external ClickHouse database via the HTTP interface. Required parameters:

Parameter	Description
`global.clickhouse.main.url`	URL for the database
`global.clickhouse.main.username`	Database Username
`global.clickhouse.main.password.secret`	Name of the configured secret
`global.clickhouse.main.password.key`	Which key to use as the password within the secret
`global.clickhouse.main.database`	Database name

Using ClickHouse is intended for experimenting and testing purposes only at the moment.

Configuring the password

The password can be set manually using the kubectl CLI tool:

kubectl create secret generic gitlab-clickhouse-password --from-literal="main_password=PASSWORD_HERE"
