MinIO is supposed to automatically reload itself when the certificate
changes, but this does not appear to happen in all cases. To ensure the
updated certificate gets used, we need to send SIGHUP to the MinIO
server process.
MinIO exposes metrics in Prometheus exposition format. By default, it
requires an authentication token to access the metrics, but I was unable
to get this to work. Fortunately, it can be configured to allow
anonymous access to the metrics, which is fine, in my opinion.
[MinIO][0] is an S3-compatible object storage server. It is designed to
provide storage for cloud-native applications for on-premises
deployments.
MinIO has not been packaged for Fedora (yet?). As such, the best way to
deploy it is usining its official container image. Here, we are using
`podman-systemd-generator` (Quadlet) to generate a systemd service
unit to manage the container process.
