Deployment

Versioning rule

The version number recorded in this file (i.e. checked into git) is the current online version — the version of the latest published Docker image.
When any changes are made, the new Docker image version must bump the minor number of the latest git version (e.g. latest is 1.9 → new image is 1.10).
Whenever a new image is built and pushed, update the commands below in the same commit, so the checked-in version always matches the published image.

Publishing (automated)

Use publish.sh — it reads the current version from this file, bumps the minor, updates this file, builds the image with the version build-arg and pushes it:

./publish.sh        # bump minor of the current version (e.g. 1.10 -> 1.11)
./publish.sh 2.0    # publish an explicit version instead

Cross-building

The dev machine is an Apple Silicon Mac (arm64) while the target server is Ubuntu 22.04 x86_64, so images are cross-built with docker buildx for linux/amd64 and pushed straight to the registry (--push). Requires a buildx builder with amd64 support (OrbStack / Docker Desktop provide one by default, e.g. via QEMU emulation).

Build & push (manual)

docker buildx build --platform linux/amd64 \
  --build-arg VERSION=1.17 \
  -t 192.168.2.212:3000/tigeren/metube:1.17 \
  --push .

Run

docker compose up -d --build --force-recreate
