Thanks for reporting! We will book some time in the next release for this.
We will need to provision a Secret with the new my.cnf
format:
[client]
user = foo
password = foo123
[client.servers]
user = bar
password = bar123
It also seems like they have multi target support , which implies that we no longer need to run the exporter as sidecar container and instead it could be a standalone deployment with multiple targets. This would make MariaDB upgrades easier, as upgrading the exporter can be done independently from the MariaDB StatetulSet
.
from mariadb-operator.
See mysqld_exporter helm chart for reference:
https://github.com/prometheus-community/helm-charts/tree/main/charts/prometheus-mysql-exporter/templates
from mariadb-operator.
The following PoC demostrates how we can create a separate Deployment
object for the exporter and scrape multiple MariaDB instances from there:
This implies that we don't need to add an extra sidecar container to each MariaDB instance to export its metrics, so basically the exporter lifecycle (including upgrades !) won't affect the uptime of the MariaDB!
