A quick and dirty way to create a host for development purposes

1. Create operating system if none exist, for example CentOS 7.5
2. Create a domain example.com
3. Set up Host parameters
4. Set up Operating System params
5. Set up an interface with fake MAC address and use the example domain

Networking class

Class 1

Browser example and basic networking

• Typing www.wikipedia.com in the browser
• We need DNS server for domain to ip address mapping
• Before that, we can use DHCP (which does a number of things). DHCP can ask the ISP provider for a DNS server to use
  • DHCP
  • can also provide Static IP address

With dynflow actions, the disable repository tasks are run concurrently, and there are race conditions. I used the following to debug:

Seeing dynflow/foreman-task errors and strange behavior on the dev box. Using this gist to collect the errrors. Not sure what is related, but documenting everything here.

Odd Behaviors:

• Tasks stuck in "planning" state

Tracebacks

• Seeing this one on a fresh box while enabling and disabling RH repos
