setting up new cluster

Nodes are pi3 and pi4, IPs 192.168.1.151 and 192.168.1.215 respectively.

setup hosts

TODO: I should probably make part of this in one host, then duplicate the sd-card. This shit takes forever to finish.

# export IP=192.168.1.151
# export IP=192.168.1.215

# make ssh pi3 and ssh pi4 work
echo '
Host pi3 pi4
  User ubuntu

Host pi3
  HostName pi3.local

Host pi4
  HostName pi4.local
' >>~/.ssh/config

# will ask to change password et al
ssh ubuntu@$IP

# copy ssh pubkey
ssh-copy-id ubuntu@$IP

# ssh again
