A docker network is a regular network that transfers packets between containers and used by containers to communicate with the host (through the docker0 bridge and a veth pair). a kubernetes namespace is a logical way to isolate / divide / separate cluster resources between multiple users and provides scope for names. First, there is an un-necessary cmd.exe command processor (aka shell) being invoked. So if you start a container by default it will be created inside the bridge (docker0) network. It defines: source image, list of commands executed while creating the image, list of commands to automatic run, See the docker network create reference or the output of docker network create --help for details. This image will be pulled if it is not already available locally. It is owned by A Medium Corporation. And if you can talk to the network, you can get secrets over the network.
