There was a recent post about whether to enable ufw and it made me ask: how protected I am from a rogue docker container? I have a single server with 15-20 docker containers running at any given time. Should one get hacked or be malicious from the get go, are there (hopefully easy to implement for an armchair sysadmin) best practices to mitigate such an event? Thanks!
This is not true sorry. Even in k8s any container has access to any other container in the same pod or in dockers case on the same host. In k8s you can at least add network profiles. If its a host or MACVLAN container it gets worse if no proper isolation is configured on the network level.
