Rancher services updating by itself

I am using rancher v1.6.10 and am running into a few issues.

I am running nodejs dockerized apps, and I’ve been having issues with intermittent 503 status codes.

I put in some external monitoring, and I saw that I got some 503s at a specific time, I went to look into the service log, and it had updated, but I never triggered any updates.

Why are the services updating by themselves? Is this normal behavior?
