6/ If I wanted to set a static IP address on an interface which should be persisted over reboot, should I use the command:

• ip
• nmcli
• ifconfig
• ipconfig

Part 2/ Solve this Problem

Fix Dockerfile in the repo so you can see "Hello Kolomolo" in your browser on http://localhost:80 after container start

Part 3/ Learn Something New

Setup 2 linux machines for free on a cloud provider of your choice. Server A should be setup to be a salt master

• https://docs.saltproject.io/en/latest/topics/installation/index.html
• Configure so all minions have installed nginx
• Configure nginx on minions with index.html file which says “Hello Kolomolo” Server B to be salt minion, that connects to the master
• Allow port 80 on the cloud firewall (if any), so we can reach see the Hello Kolomolo message.

Upload to your repo:

• Readme file with the Answers to Section 1
• The corrected Docker file
• Top.sls and state files in a dir called salt
