VETH is a what device?

A virtual Ethernet (VETH) device is a pair of layer 2 network endpoints that connect kernel entities to each other. With Docker, the default network setup is to use a VETH pair to connect the running container's network namespace to the docker0 bridge.

Great, so what's the problem we are solving?

When needing to troubleshoot the network stack of a single container and multiple are running, how do you know which VETH device to troubleshoot?

This is a quick note on what to modify when building Hadoop with rootless podman.

• First, ensure the following directories exist on the host OS. If not then create them with mkdir

  • "${HOME}"/.m2
  • "${HOME}"/.gnupg

• This is what the current commit ID is for HEAD. Perhaps this will be fixed by the time you read it.

$ git rev-parse HEAD
