Error on Docker Boot about uptime-kuma-web-api

[tigunia-martin]

Long story short, it boils down to incorrect permissions on the volume where the sqlite database file is stored.
The author tried to set the volume to rwx with the line on the docker-compose.yml that says:

  volumes:
    - ./db:/db:rwx

but that is likely throwing errors because ro is valid and rw is valid, but I don't think rwx is valid

A way to work around this is to set the db folder to have the correct permissions. There are many ways to accomplish this, but the following command should work best and be least amount of changed permissions.

1. Stop the backend container
2. mount up another container, like busybox or similar, with the api volume attached so you can modify permissions.
   Something like docker run --rm -it -v your-kuma-api-volume:/kuma alpine chown -R 100 /kuma
3. stop the other container
4. re-run docker-compose up

Everything should boot up at this point.

@tigunia-martin thanks for the fix, I think it's easier to change permissions on the folder: chmod -R 777 db for example.
This works only if you have acces to OS and terminal.

Works for me and should for others too. This can be done through entrypoint.sh as well, as extra one command line.
