How to recover pictures and files from failed MacOS / HFS+ hard drive with Linux

A couple months ago, a friend ask me to repair a failing macintosh.

It appears the hard drive has multiple failures from SMART anlysis.

Next reboot... Oh crap, the operating system does not start anymore. The drive contains 10 years of pictures to recover. A heart pinch :'(

Important thing to know, if (certainely) the disk is crypted and you don't know the principal user login password,

# find the kube node of the running pod, appear next to hostIP, and note containerID hash
kubectl get pod mypod -o json
# -> save hostIP
# -> save containerID

# connect to the node and find the pods unique network interface index inside it's container
docker exec containerID /bin/bash -c 'cat /sys/class/net/eth0/iflink'
# -> returns index

# locate the interface of the node
