Eneko,
For clarification, this is the link I used to fix my particular docker issue:
https://github.com/Debian/docker.io/blob/master/debian/README.Debian <https://github.com/Debian/docker.io/blob/master/debian/README.Debian>
The specific issue for me was as follows:
My cluster is running:
* Debian 10 with DefaultRelease=buster-backports * Ceph packages from the Debian repo * Non-container installation (except for Grafana/Prometheus/Node Exporter) * Docker.io repo added by ceph-ansible
The Grafana and Prometheus containers stopped working after running apt-get dist-upgrade (via ceph-ansible) to pick up the latest Debian Ceph packages . The systemd log messages were similar to those reported by Radoslav. A Google search led me to the link above. The suggested addition to the kernel command line fixed the issue.

We have several updated Debian 10 servers running Docker containers (not related to Ceph) without needing this tuning. Docker is from Debian repos but we had a couple with docker.io <http://docker.io> version without issues.
