Error Converting Docker Commands to docker-compose.yml
In the container timescaledb you are actually mounting the /var/lib/postgresql/data to ./timescaledb and hence, if you want to use the same volume for the wale container, you can edit the wale container like:
... volumes: - ./backups:/backups - ./timescaledb:/var/lib/postgresql/data...In this case, both of the containers will be able to read and write from the same mounted volume to your local machine.
Also, remember to remove this part as it is not a valid command in docker-compose:
volumes_from: - tsdb
