Pick an IP for a local vm for infrastructure projects

[olizilla]

We need to pick a unique local IP address for all our local test vms, for infrastructure projects. If we use the same one, vagrant and ansible get in a twist.

The plan:

10.100.<# for project>.<# for app or server>

• Increment the 3rd quad per project. -
• Increment the 4th quad per server in that project.
• Pick numbers not in the list below.
• Update this comment when you add one.

Current list from /etc/hosts

What?

The snippet of etc hosts below shows the pattern.

10.100.115.100  dev.sohiworld.com dev-api.sohiworld.com
10.100.115.101  dev-ops.sohiworld.com
10.100.116.100  dev.sohiworld.com dev-api.sohiworld.com
10.100.116.101  dev-ops.sohiworld.com

The pattern is 10.100.xxx.10y where

• xxx is the subnet for the project e.g. sohi, kudos etc and > 100 and not in the list below
• y is per server in that project, eg. app is 100, ops is 101.

Examples.

The app and ops servers for sohiworld:

10.100.116.100  dev.sohiworld.com dev-api.sohiworld.com
10.100.116.101  dev-ops.sohiworld.com

The app and ops servers for kudos health:

10.100.115.100  dev.sohiworld.com dev-api.sohiworld.com
10.100.115.101  dev-ops.sohiworld.com
