HELP WANTED : Easy way to run Clair V4 in kubernetes and scan images

[efiegehen93]

Description of Problem / Feature Request

Hey guys, is there an easy way to run Clair v4 in k8s, justo clair in combo mode, postgres DB and clairctl.
Not able to find a good tutorial, i'm using this docker image : quay.io/coreos/clair:v4.1.0

The following config.yaml

introspection_addr: localhost:8089
http_listen_addr: localhost:8080
log_level: debug
indexer:
  connstring: 'postgresql://postgres:postgres@clairv4-postgres/clair'
  scanlock_retry: 10
  layer_scan_concurrency: 5
  migrations: true
matcher:
  indexer_addr: "localhost:8080"
  connstring: 'postgresql://postgres:postgres@clairv4-postgres/clair'
  max_conn_pool: 100
  run: ""
  migrations: true
  updater_sets:
  - "alpine"
  - "aws"
  - "debian"
  - "oracle"
  - "photon"
  - "pyupio"
  - "rhel"
  - "suse"
  - "ubuntu"
notifier:
  indexer_addr: http://clairv4/
  matcher_addr: http://clairv4/
  connstring: 'postgresql://postgres:postgres@clairv4-postgres/clair'
  migrations: true
  delivery_interval: 1m
  poll_interval: 5m
trace:
  name: "jaeger"
  probability: 1
  jaeger:
    agent:
      endpoint: "localhost:6831"
    service_name: "clairv4"
metrics:
  name: "prometheus"

Andi'm trying also to install into a golang image, clairctl with :
GO111MODULE=on go get github.com/quay/clair/v4/cmd/clairctl@latest

But it doesn't work.....

Getting some errors also in clair logs :

{"level":"error","component":"libvuln/updates/Manager.Start","error":"updating errors:\nRHEL8-rhvh-4: unexpected EOF\nRHEL6-satellite-6.2: bzip2 data invalid: bad magic value in continuation file\nRHEL6-satellite-5.8: bzip2 data invalid: bad magic value in continuation file\n","time":"2021-05-31T22:39:17Z","message":"errors encountered during updater run"}
{"level":"error","component":"notifier/keymanager/Manager.loop","time":"2021-05-31T22:45:14Z","message":"received error when bumping public key expiration"}

I know that clair V2 has a healthcheck but does V4 also got one ?
What is the easy way to install clairctl for V4 and run a report ?

Expected Outcome

Run Clair V4 in k8s easy mode

Actual Outcome

None
