Clairv4 cannot get vulnerability reports in distributed mode.

[bluefriday]

Description of Problem / Feature Request

I'm intersted in clairv4
Firstly, I ran clairv4 in combo mode with kubernetes cluster.
In this case, I could scan and report with vulnerability (I used api).

But, with distributed mode (same kubernetes cluster), I cannot receive vulnerability report even though can scan :(

Expected Outcome

The API allows you to scan for image vulnerabilities and receive vulnerability reports.

Actual Outcome

The API allows you to scan for image vulnerabilities, but does not receive vulnerability reports.

It looks like the matcher config doesn't have a real URL for the indexer.

It looks like the matcher config doesn't have a real URL for the indexer.
I fixed the issue by setting it up as you said.
thank you.
