Fix Docker compose setup to run on Linux - #678
Conversation
- compose.yml: add MySQL healthcheck and gate services on service_healthy, set MYSQL_ROOT_HOST so containers can connect as root, wire GRPC_LOGIN_IP for world, add restart policies, remove deprecated links and redundant command overrides, drop unused web 80/443 mappings, and move file-ingest under an 'ingest' compose profile so it runs manually on demand. - Maple2.Server.Game/Dockerfile: remove COPY of non-existent Scripting/Scripts directory which broke the image build. - .env.example: document MS2_DOCKER_DATA_FOLDER and GRPC_LOGIN_IP for docker.

Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk:🟡 Moderate · up to The Compose setup improves Linux startup reliability, but it still permits MySQL root connections from any host and may use a predictable fallback password, creating a risk of unauthorized database access in deployments that do not override the password. Merge should wait for a strong required password and appropriate network restriction, or explicit owner acceptance. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

- compose.yml: document the on-demand ingest run command and ensure a trailing newline. - .env.example: note that DB_IP must be commented out when running with docker so DotEnv.Load() doesn't override the container's DB_IP=mysql.

In `@compose.yml`:
- Around line 172-173: Harden the MySQL service configuration by removing the
default fallback from MYSQL_ROOT_PASSWORD and requiring an explicitly supplied
secret, eliminating MYSQL_ROOT_HOST wildcard access, and configuring the
application to use a least-privileged non-root database user. Change the 3306
port mapping to bind only to localhost unless external host access is explicitly
required.
- Line 159: Align the web port configuration across Program.cs, .env.example,
Target.WebUri, and the Compose ports mapping so WEB_PORT’s default and the
externally published port are identical and the listener is reachable; update
the relevant configuration values consistently without changing unrelated
services.

The web service previously published a hardcoded 4001:4001 while the container listens on WEB_PORT, so a fresh setup following .env.example (4000) forwarded to a port nothing listened on. Publish the same port WEB_PORT resolves to, keeping the server listener and client-facing URL consistent.

Summary
Fixes the docker compose stack so the project actually builds and runs on Linux.
Changes
compose.yml
depends_on: condition: service_healthy. Previously every server raced the ~30s MySQL startup and crashed on connect.MYSQL_ROOT_HOST: "%"so the server containers can connect to MySQL asroot(the official image only allows root from localhost by default).GRPC_LOGIN_IP: loginfor the world server (it previously defaulted to its own loopback).restart: unless-stoppedto all servers so they retry until the DB / ingest are ready.links:blocks and redundantcommand:overrides that doubled the ENTRYPOINT args.80:80/443:443web mappings (the web server only listens onWEB_PORT, HTTPS is commented out in code).file-ingestunder aningestcompose profile so it runs manually on demand instead of on everydocker compose up.Maple2.Server.Game/Dockerfile: removed the
COPY .../Scripting/Scriptsstep — that directory does not exist in the repo and guaranteed the image build failure..env.example: documented
MS2_DOCKER_DATA_FOLDER(the docker-only client data path, already referenced by compose but previously undefined),GRPC_LOGIN_IP, and noted thatMS2_DATA_FOLDER/DB_IPmust be commented out under docker soDotEnv.Load()doesn't override the container values.Running on Linux
Configure env
Edit
.env:MS2_DOCKER_DATA_FOLDERto the host path of your MapleStory2Datafolder.MS2_DATA_FOLDERandDB_IP(docker-only instructions are in the file).DB_PASSWORDmust match what the stack uses for MySQL.The client
Datafolder must containXml.m2d,Resource/Exported.m2d, andServer.m2d(and their.m2hfiles).Server.m2d/Server.m2hare only published in thev1.xreleases of MS2Community/MapleStory2-XML — the URL insetup.ps1currently 404s.Build
