# Some containers do not provide netstat or lsof. This command will get you the local IP a session is established on
# In short: This gets the output from namespace 1 (where usually the process is running inside the container), filters out the field where the hex IP is located and converts it into a readable IP in the right format. (some fields are inverted etc)
# Benefit is that you dont need netstat installed to see connections.

Rancher only supports specific SSH key formats. When you try to add a ssh-key it often will fail and give the following error because the format is incorrect: 
data does not contain a valid RSA or ECDSA private key
This issue gave the idea that the Rancher interface has limited SSH key support: https://github.com/rancher/fleet/issues/138

Generate the private key and public key:
ssh-keygen -t rsa -b 4096 -m pem -C "Rancher chart ssh-key"

Since there is no password option in the Rancher interface, provide the keys without a passphrase and place the keys to a location of your choice. 
Test the key against Github to validate it is correct:
ssh-agent bash -c 'ssh-add /Users/USERNAME/.ssh/id_rsa_rancher_chart; git clone git@github.com:REPOSITORY/charts.git'
