you can create your own new network like --network="anyname" this is done to isolate the services from different container. suppose the same service are running in different containers, but the port mapping remains same, the first container starts well , but the same service from second container will fail. so to avoid this, either change the ...
# service docker restart Check the result: $ docker network create foo $ docker network inspect foo | grep Subnet "Subnet": "10.10.1.0/24" It works for docker-compose too. Your "bip": "192.168.2.1/24" works for bridge0 only. It means that any container which run without --network will use this default network.
Maybe looking at macvlan networks might give a better use case than the bridge networks. macvlan networks create MACVLAN type slave network interfaces virtually attached to a host (hardware) network interface, the master. MACVLANs are like multiple network interfaces with separate MAC addresses on the same single HW network card.
The external network must already exist (e.g. "my-pre-existing-network"), it could be a docker network created from a different docker-compose environment or a docker network created using the docker network create command. Note: docker-compose networks are prefixed with COMPOSE_PROJECT_NAME. You can use docker network ls to list existing networks.
docker network create your-network-name Then, connect your containers to the network that you just created: docker network connect your-network-name container-name Or connect with the run command: docker run --network=your-network-name your-image Now, containers in the same network your-network-name can talk to each others via container name.
My colleague came up with this and it works with our company network drive and it might help someone out there. We start by creating a docker volume named mydockervolume. docker volume create --driver local --opt type=cifs --opt device=//networkdrive-ip/Folder --opt o=user=yourusername,domain=yourdomain,password=yourpassword mydockervolume
First you need to create your own docker network (mynet123) docker network create --subnet=172.18.0.0/16 mynet123 then, simply run the image (I'll take ubuntu as example) docker run --net mynet123 --ip 172.18.0.22 -it ubuntu bash then in ubuntu shell. ip addr Additionally you could use--hostname to specify a hostname
$ docker network create test-net $ docker run --net test-net --name nc-server -d nicolaka/netshoot nc -vl ...
$ docker network create abcd --subnet 172.17.0.0/16 The log output from your Docker deamon indicates that it's actually trying to allocate almost each of those 31 default subnets. There's only two possible reasons why that allocation may fail. Name server overlap. Docker won't use a default subnet if your DNS server belongs to that subnet.
docker network create -d macvlan \ --ipam-driver=dhcp \ -o parent=eth0 \ --ipam-opt dhcp_interface=eth0 mcv0 Since this requires re-compiling the binary, an alternate solution could be to assign static IP addresses to all your containers using the "--ip" option to docker run/compose, and get a DNS entry for your hostname assigned to this IP ...
