Split scylla container supervisord processes into separate containers and remove supervisord #1769

Open tnozicka opened 4 months ago

tnozicka commented 4 months ago

Currently, multiple services like:

scylla
node-exporter
jmx
sshd
supervisord
scylla-housekeeping
operator sidecar
rsyslog This is in contrast to all guidelines or the fact that cgroups limit can only be set per container, so anything else hurts ScyllaDB latency. We should remove the services that we don't need on Kubernetes and split the rest into dedicated containers and not use supervisord anymore.
