Okay, I've been able to move on. I copied the

/deploy/docker/Dockerfile-osctrl-prod

and

/deploy/docker/docker-compose-prod.yml

files from version 0.2.7 to 0.2.9. In the root folder (and not in

/deploy/docker/

, as I originally did), I executed

cp .env.example .env

and changed the configuration for myself. Run

./deploy/docker/dockerize.sh -u -b -f

. Compilation started and ended with an error:

Step 7/52 : RUN go build -o bin/osctrl-tls tls/*.go
  ---> Running in 0ff4198914a6
