docker compose depends_on anchor mix
I have the following anchor in docker compose:
Where do the docker image and docker container names come from?
To start a Docker container I ran the command docker compose up -d. (Actually, the -d switch is unimportant.)
docker-compose check if an instance already running
Assume we have 3 projects – Project 1, Project 2 and Project 3. Now, each of those Projects needs to have access to a nginx instance that acts as a proxy for the local environment. This instance is it’s own seperate container and started via docker run -d --network=local_network --name nginx -p 80:80 nginx_local. My other projects are started via docker-compose.
