  • Kops default installation comes with kubenet, which has limitations with routing if cluster nodes count is more than 50.We need to use CNI plugins eg:calico,flannel etc
  • By default all the pods in a cluster can talk to each other(flat network), we can restrict this inter pod communication by using some policy rules with calico or flannel and other plugins

Eg:$docker run -itd <image> 5.

On a user-defined bridge network, containers can resolve each other by name or alias. We can create bridge network as shown below      $docker network create <network name>   If we don't specify any network driver then by default it is bridge and we can define subnet and default gateways by using different flagsf we can add container to user defined network 2 ways While creating docker container from image using --network or --net flag        $docker run --it --net=<network na...
