If you need to install Docker Image:

docker image inspect europe-west3-docker.pkg.dev/yourown-chat/docker/mattermost:<tag_with_patched>

How to build the binary locally

Go to the server module:

cd server

If go.work is missing for some reason, create it once:

go work init
go work use .
go work use ./public

Build a binary for your machine, mostly to check that everything compiles:

go build -buildvcs=false -o ./bin/mattermost ./cmd/mattermost

Check it:

./bin/mattermost version

If you need the same linux binary that goes into the Docker image:

CGO_ENABLED=0 GOOS=linux GOARCH=amd64 \
	go build -buildvcs=false -ldflags='-s -w' \
	-o ./bin/mattermost-linux-amd64 \
	./cmd/mattermost

Or build only the binary inside Docker, without building the full image:

docker run --rm \
	-v "$PWD/server:/src/server" \
	-v gomod-cache:/go/pkg/mod \
	-v gobuild-cache:/root/.cache/go-build \
	-w /src/server \
	golang:1.26-alpine \
	sh -lc 'go work init 2>/dev/null || true; go work use . ./public; CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -buildvcs=false -ldflags="-s -w" -o ./bin/mattermost-linux-amd64 ./cmd/mattermost'

Short version: for a quick compile check, go build ./cmd/mattermost is usually enough. For the container, build with GOOS=linux GOARCH=amd64.

How to run the container

If you changed code and want to test it locally, build the full Docker image from the repo root with the same tag that compose already uses:

docker build \
	-t europe-west3-docker.pkg.dev/yourown-chat/docker/mattermost:<tag_with_patched> \
	.

Then recreate only the patched Mattermost container:

cd /Users/pilprod/Projects/chatops/mvp
docker compose up -d --force-recreate --no-deps mattermost-patched

After push to public-pached-11.7, Cloud Build publishes this image:

europe-west3-docker.pkg.dev/yourown-chat/docker/mattermost:<tag_with_patched>

On the server, pull it and recreate only the patched Mattermost container:

cd ~/chat-stack
docker compose pull mattermost-patched
docker compose up -d --force-recreate mattermost-patched

Quick check after restart:

docker compose logs -f --tail=100 mattermost-patched
