LSB Server - Docker

Containerized version of LandSandBoat server emulator.

Pre-configured build and runtime environments for a fast and easy install. Supports live editing on the host machine for a seamless experience.

Usage

docker compose up --build --detach

That's it! All the setup is handled for you. Check out the official LSB documentation for more information. Some adjustments will need to be made while working with Docker. LSD specific information will be added here over time.

docker compose stop / docker compose start
- Use these to stop/start the server when rebuilding isn't necessary.
docker compose build
- Builds the image. With caching, this basically just rebuilds the executables if needed. Use --no-cache for a full clean build.
docker compose down
- Shuts down and removes the containers.

Updating

git submodule update --remote --merge
- This will pull the latest changes from upstream LSB. Run docker compose up --build --detach again to rebuild and start/restart the containers.
- You can also just change to the server directory and treat it as its own repo (change branch, fork, apply patches, etc.)

Alpine

Alpine Linux is a minimal image that comes in at about half the size of the Ubuntu image (excluding bind mounted files/directories). The Alpine build is experimental and unsupported by LSB. It uses a newer version of GCC and the musl libc. Use at your own risk.

docker compose -f ./docker-compose.yml -f ./docker-compose.alpine.yml up --build --detach

Notes

The image is built with a default user and group named xiadmin with UID and GID 1000.
- You can supply the build args UNAME, UGROUP, UID, GID to change these.
  - docker compose build --build-arg UID="$(id -u)" --build-arg GID="$(id -g)" --build-arg UNAME="$(whoami)"
If using WSL with Windows, make sure the project is stored in the WSL file system for best performance.
- You may experience issues related to the system clock. Using sudo hwclock --hctosys in WSL may help.
Secure database passwords and a default user and database name are generated into config/.env to simplify the setup process.
- Optional - You can manually create this before building the containers with these variables:
```
MARIADB_DATABASE=
MARIADB_USER=
MARIADB_PASSWORD=
MARIADB_ROOT_PASSWORD=
```
  Otherwise, the default user is xiadmin, the default database is xidb, and the password is randomly generated.
  - If config/.env is automatically generated, a random initial password for the root user will be generated and printed to stdout (check your build log!)
- Because environment variables are used, the server settings SQL_LOGIN, SQL_PASSWORD, and SQL_DATABASE (all located in network.lua) are not used.
Because LSB uses Git during the build and update process, changes to the Git metadata will trigger an image rebuild, but with caching this shouldn't be significant.
