Nginx Disappeared after nextcloud update?

[Craterbrain]

It's been a while since I've used this install script, but I think it had Nginx running in docker. I noticed I was getting a 404, and that sometimes happens after an update. Rebooted my vps and it still didn't work. Checked running containers and Nginx wasn't running. Postgres is also complaining " role "postgres" does not exist". Maybe I'm not on the right track, but please do let me know where I should troubleshoot.
Also, if I were to run the playbook again with all my current config files would it still work? I would rather not lose my data even though I have backups of most.
EDIT: I found this. #85
Is the any way to resolve this without reinstall?

This happens occasionally to me also. nginx disappears.
What I do is, first take a snapshot of VM (just in case, I am running docker inside xen) and as root and run your current yml
ansible-playbook nextdocker.yml
It does not harm my config or other stuff, just reinstall missing nginx.
Cheers.

It worked!

Just a few notes:
Update and upgrade server before running script or it may fail. (Debian 10)

If NC Passwords loses your password do:
docker exec -ti -u 82 nextcloud ./occ passwords:backup:list
docker exec -ti -u 82 nextcloud ./occ passwords:backup:restore <BACKUP_NAME>

It's been a while since I've used this install script,

you may check commit a0c8e77
I changed the nginx container labels "com.centurylinklabs.watchtower.depends-on" to make watchtower aware to restart all container correctly.

if you are using a "very old" version of this playbook don't use "git pull". not all commits are backward compatible. (e.g. update to traefik v2 3752a95)

Thanks! That should do the trick. I'll edit the file.
