- Docker creates its own isolated docker network where containers are running.
- Containers in same Docker Network can communicate with each-other just with the
container namewithout needinghost:port - Docker provides some default network
# list docker networks
docker network ls
# create new network
docker network create my-network
# run container in specific network my-network
docker run -d -p 6000:6379 -e <env_var_1=value> -e <env_var_2=value> --name local-redis --net my-network redis
# multi line command
# env var can be found in details from docker hub for the image
