Trying to deploy elk as a docker service with certificate

Elastic Stack Elasticsearch
1

Hello all.

Here is the problem: I have deployed an elk stack using docker compose, which worked fine up until recently. Now after a while one or more of the containers go down for some reason, and I am guessing it may be because of the workload. Anyways, I have decided to deploy it as a docker service, so the containers can automatically go up again if they drop.

When I deployed it, the containers started to crash all the time, saying that the certificate folder doesn't exist. I connected to one of the containers with bash, and the permissions for the certificate folder was changed to root, instead of Elasticsearch or kibana. When I use docker compose this doesn't happen.

Any ideas what could be causing this?
