Why is my hostname resolution taking so long?
I was able to fix this issue by explicitly setting the HostName using scutil to be the same value as LocalHostName:
$ scutil --set HostName $(scutil --get LocalHostName)
Now:
$ sudo scutil --set HostName MacBook-Pro
$ time python -c 'import socket; print(socket.getfqdn())'
MacBook-Pro
python -c 'import socket; print(socket.getfqdn())' 0.01s user 0.00s system 86% cpu 0.016 total
I was confused before because of the following:

Local Kubernetes setup on macOS with minikube on VirtualBox and local Docker registry

Requirements

Minikube requires that VT-x/AMD-v virtualization is enabled in BIOS. To check that this is enabled on OSX / macOS run:

sysctl -a | grep machdep.cpu.features | grep VMX

If there's output, you're good!

Getting Amazon Linux working with X11
# These instructions assume you are using a Linux or Mac machine as
# the “local” machine and an Amazon Linux as the “remote” machine.
# Here’s one way to get X11 working between the two.
# on the local machine (Linux or Mac with X11 already installed)
$ ssh -X -i <amazon_key.pem> ec2-user@<remote_ec2_box_name>
# then on the remote Amazon Linux EC2 box
$ sudo yum install xauth
$ sudo yum install xterm

How can I use docker without sudo?
  1. Add the docker group if it doesn't already exist:

  1. Add the connected user "${USER}" to the docker group. Change the user name to match your preferred user:
sudo gpasswd -a ${USER} docker
