Docker image + Compose scaffolding for TShock v5.2.4 (Terraria 1.4.4.9), plus a GitHub Actions workflow that builds and pushes to a custom registry (cr.nym.sh).

Repo layout

Dockerfile — builds the image by downloading the official TShock release asset
docker-compose.yml — example: shared ./worlds + separate per-server state under ./data/worldX
.github/workflows/build-and-push.yml — CI to build + push images to your registry

Local build

docker build -t tshock:5.2.4 .

Local run (two worlds, separate state)

mkdir -p worlds data/world1 data/world2
docker compose up world1   # first-time interactive prompts, Ctrl+C when done
docker compose up world2   # first-time interactive prompts, Ctrl+C when done
docker compose up -d

Players connect to:

host:7777 → world1
host:7778 → world2

CI: push to cr.nym.sh

1) Create GitHub repo secrets

In your GitHub repo settings:

CRNYM_REGISTRY_USERNAME
CRNYM_REGISTRY_PASSWORD

These should be credentials that can push to your registry.

2) Set image name (optional)

By default the workflow pushes to:

cr.nym.sh/<github-owner>/tshock

If you want a different path/name, edit IMAGE_NAME in the workflow.

3) Triggering

The workflow runs on:

pushes to main
git tags like v5.2.4 (recommended: tag releases)
manual runs (workflow_dispatch)
a weekly scheduled rebuild (useful for base image security updates)

Tag strategy

latest on default branch (main)
vX.Y.Z tag pushes also publish X.Y.Z
also publishes a short SHA tag for traceability

Notes / gotchas

Don’t run two servers pointed at the same .wld file at once.
Keeping ./worlds shared is fine as long as each server uses a different world file.
On Linux, if the container can’t write to your bind mounts, you may need:
```
sudo chown -R 10001:10001 worlds data
```
