We talked about increasing the size of Pod and maybe Service IPv4 ranges (the initial context probably was T296303: New Kubernetes nodes may end up with no Pod IPv4 block assigned).
For ML clusters this has already been done (for different reasons) in:
- T302701: Re-evaluate ip pools for ml-serve-{eqiad,codfw}
- T304673: Re-initialize the Kubernetes ML Serve clusters
We should decide on new ranges for wikikube eqiad and codfw here (should we switch to the "ask alex" kubernetes IP space https://netbox.wikimedia.org/ipam/prefixes/378/ ? )
Current ranges are:
- eqiad pod 10.64.64.0/21
- eqiad service 10.64.72.0/24
- codfw pod 10.192.64.0/21
- codfw service 10.192.72.0/24
