In my configuration, I have 4 servers that run with an instance of the same Docker image. I have been asked to link each of them with a Memcache server, but also to make sure that no one from outside is allowed the connect the image, so that the datas can be trusted.
Basically, the command
telnet 172.18.0.1:11211 from outside the containers would return
connection refused, while
telnet memcached:11211 from inside one of the running containers linked to the Memcached image will start the connection.
EDIT: Forgot the docker-compose.yml file
It’s a simplified version, but the “normal” one just adds up specific and useless datas
version: '2' services: web: depends_on: - mysql ports: - 8080:80 mysql: image: mysql:5.7 ports: - 3306:3306 memcached: image: memcached depends_on: - web
Is there a way to do that, or at least to approach this result?
Thank you in advance.
