The existing port 8888 and other ports in this file likely have a name field to identify their purpose (e.g., for use in Service selectors or readability). This new port entry is missing a name field. Consider adding a descriptive name such as span-metrics to be consistent with the other port definitions and to make it clear what this port is used for.

Suggested change

	- containerPort: 8889
	- containerPort: 8889
	name: span-metrics

this should not be required. This PR already exposed the necessary service port 240e4a0

We are currently using prometheus to store span metrics since this PR went in.

Also the containerPort does nothing.

This can be merged though with no harm and is still good information to add.
