This is an add-on for Docker where you can specify whole sets of services into a single file and start them at once. You can also port container setups to other servers more easily.
| inspect service | docker inspect $(docker-compose ps -q SERVICENAME) |
|---|---|
| inspect all services | docker inspect $(docker-compose ps -q) |
| execute something in a container | docker exec CONTAINERNAME COMMAND |
| get a shell in a container | docker exec CONTAINERNAME sh |
| show all mounted paths | docker inspect -f '{{ ..:index-.mounts-0-.source }}' $(docker-compose ps -q) |
docker-compose build --no-cache
version: '3' services: […] environment: - VIRTUAL_HOST=example.tilde.fun - LETSENCRYPT_HOST=example.tilde.fun networks: - webproxy […] networks: […] webproxy: external: true
docker kill --signal=HUP docker-gen

Maybe there's still a volume left over from docker-compose down? Check with docker volume ls and remove with docker volume prune and docker volume rm.
Do not mount the folder where your docker-compose.yml and env-files are into a container. If your container is breached, one could easily gain root access to the whole host system!
Do use a reverse proxy. It makes handling SSL certificates and load balancing much easier.
