⚠️ Store []ResolvedPortSpec in ReferencedMachineResources #1951

mdbooth · 2024-03-15T13:37:11Z

The purpose of this change is fix an issue where we are storing unresolved references in ReferencedMachineResources. Specifically we are storing a PortOpts, which is a user-intent struct. PortOpts can contain unresolved references to both subnets and security groups, as well fields requiring additional processing which reference external objects: the port name, description, and tags.

We create a new type, ResolvedPortSpec, which can contain only fully resolved data. This can be seen in the new signature of CreatePorts(), which no longer requires any source of data other than the []ResolvedPortSpec from ReferencedMachineResources, and is now greatly simplified.

Fully resolving the port name also allows a simplification in port adoption.

All of the complexity now moves to ConstructPorts(), which is updated to return []ResolvedPortSpec instead of []PortOpts. ConstructPorts() is updated to resolve security groups, port name, description, and all subnets referenced in FixedIPs.

I think this sucks that description is required, but if it's to change in a later patch I'm okay.

This is the resolved port spec in the status, which will always have a description: if it didn't have a description we would have generated one. This is expected.

I think all below should be double-checked by @MaysaMacedo. It looks right to me from dual stack perspective, but this is the delicate part in this PR.

It should be just code motion with changes for context. I didn't intentionally change the logic here.

That's not very illuminating! Lets see if it was a flake.

I looked thru the code and think it looks good. Only one inline comment regarding the function clusterName that actually returns a name used for resources and is not the cluster name.

It can safely be ignored however may cause confusion for someone reading the code. When I see clusterName i almost every time ask myself why cluster.Name is not used since cluster exists almost everywhere already

+func ClusterName(cluster *clusterv1.Cluster) string {


Maybe we should call this variable something else? I get this is used for a lot of resources however it is not the clusters name.

Maybe clusterResourceName or something could work?

I really like the initiative to move this to a function since the name are present in a lot of places in the code.

That's a good point, and I agree. Confusion from this was also the cause of a bug in @EmilienM's ports series a few weeks back that took both of us working together over a day to track down. I think it's worth picking a better name.

I've pushed a separate commit which changes it everywhere. Note that clusterName in the e2e tests actually does mean cluster name, so I haven't changed it there.

mdbooth · 2024-03-22T10:38:36Z

~~I'm not going to re-run the full test on this latest push because it just updates function and variable names.~~

Actually we just broke the upgrade test with a search and replace the other day. Do I learn nothing? 🤦
