Errors migrating from docker to native

[novaclark]

After a successful test of netbox-docker v3.4.4 I want to move to a native install. Another post on this site reported success with backing up and restoring the database, per this page, but I get an error with that command:

~/projects/netbox-docker$ docker-compose exec -T postgres sh -c 'echo $POSTGRES_USER'
ERROR: The Compose file './docker-compose.yml' is invalid because:
services.netbox-housekeeping.depends_on contains an invalid type, it should be an array
services.netbox-worker.depends_on contains an invalid type, it should be an array

and I haven't been able to figure out what's causing it or how to resolve it. I found a post on reddit that recommends this command:

./manage.py dumpdata -a -o netbox-dump.json

but that led to a series of errors that I ultimately wasn't able to resolve:

~/projects/netbox-docker$ docker exec -it netbox-docker-netbox-1 sh

My docker-fu is weak, but I've been doing a lot of reading and searching and not having any success so far. I'd appreciate some assistance with this. If nothing else, I think the wiki troubleshooting page should be updated to reflect whatever the problem is with the database backup command. If the problem is me, please enlighten me!

Your docker-compose version is too old. Either update it if possible, or check if you have the plugin version installed docker compose ... instead of docker-compose ....

Alternatively you can just remove the depends_on sections from the docker-compose file if you are migrating away from the docker setup anyway.

Thanks. I replaced docker-compose with docker compose and the dump completed without error.

I'm using docker compose and still getting this error.
