SQLite to Docker

One command moves an SQLite installation into Docker. It needs Docker with the compose plugin; run it as root on the panel server:

gowave migrate to-docker

The command:

1. finds the current installation (/opt/gowave) and its .env, and checks SQLite for broken references between tables before changing anything;
2. creates /opt/gowave-docker with docker-compose.yml and .env, carrying over the same APP_SECRET and all settings, and generates a PostgreSQL password;
3. pulls the images, starts PostgreSQL, stops gowave.service and copies the data;
4. starts the panel in Docker on the same port and waits until it answers;
5. disables gowave.service; the gowave command then runs inside the container.

APP_SECRET

APP_SECRET is part of administrator password hashes, API tokens and the encryption of node SSH credentials. The command carries it over; if you move manually, use the same secret or you will not be able to log in.

If any step fails, the Docker project is removed and the old panel is started again. The SQLite file is not modified, so you can also go back later:

cd /opt/gowave-docker && docker compose down
ln -sf /opt/gowave/gowave-server /usr/local/bin/gowave
systemctl enable --now gowave

Flags: --dir <path> (project directory), --image <image>, --from <path> (old installation directory), --yes (no confirmation).
