Dockers that talk to each other

Bridge networks

Define bridge

docker network create bartek-net

network flag

When creating a new container, you can specify one or more –network flags:

docker run --detach --publish=8080:80 --name=webserver --network bartek-net nginx

You can test it with:

curl http://0.0.0.0:8080

Another docker with the same network flag talk to this docker by resolving name webserver:

docker run --network bartek-net byrnedo/alpine-curl http://webserver:80
