Fleet server pod not creating: ECK Operator

Open apgapg opened this issue 1 year ago • 3 comments

Bug Report

I tried deploying ECK stack by using following steps:

  1. helm repo add elastic https://helm.elastic.co && helm repo update
  2. helm upgrade --install elastic-operator elastic/eck-operator -n elastic-system --create-namespace. this deployed eck operator successfully
  3. helm upgrade --install eck-stack elastic/eck-stack -n elastic-stack --create-namespace --values ./values.yml

Here's the values.yml

eck-elasticsearch:
  enabled: true
  annotations:
    eck.k8s.elastic.co/license: basic

eck-kibana:
  enabled: true
  annotations:
    eck.k8s.elastic.co/license: basic

eck-fleet-server:
  enabled: true
  annotations:
    eck.k8s.elastic.co/license: basic
  spec:
    elasticsearchRefs:
      - name: elasticsearch
    kibanaRef:
      name: eck-stack-eck-kibana

I needed to change elasticsearchRefs and kibana ref as default were not establishing.

After above, elastic search and kibana pods are successfullt deployed, but i cant see the Fleet server pod.

I can see the fleet agent but no pod.

Here's the agent info

I can see the following error: failed to request https://eck-stack-eck-kibana-kb-http.elastic-stack.svc:5601/api/fleet/enrollment_api_keys, status is 400)

Not able to find what is the actual cause.

What did you expect to see?

A fleet server POD running.

What did you see instead? Under which circumstances?

No fleet server pod

I had similar issue /api/fleet/enrollment_api_keys, status is 400

than found in kibana logs that xpack.fleet.agentPolicies were not created

example in kibana (as you use elastic/eck-stack you can override whole spec for Kibana resource https://github.com/elastic/cloud-on-k8s/blob/main/deploy/eck-stack/charts/eck-kibana/templates/kibana.yaml#L15 )

xpack.fleet.agentPolicies:
      - name: Fleet Server on ECK policy
        id: eck-fleet-server
        ...
      - name: Elastic Agent on ECK policy
        id: eck-agent
        ...

in agent fleet server

policyID: eck-agent

resolved an issue and generate token for fleet server

@pebrc maybe yoy can help here?

as after elasticsearch version upgrade Fleet server stop working

I try delete agents/integrations/policies/tokens https://url-kibana.com/app/fleet/policies https://url-kibana.com/app/fleet/enrollment-tokens

but now when I up fleet server it returns

Reconciliation error: failed to request https://elastic-search-kb-http.elasticsearch.svc:5601/api/fleet/enrollment_api_keys, status is 400)

if check https://url-kibana.com/app/fleet/enrollment-tokens there is no any tokens

in kibana logs

@apgapg As noted, agentPolicies needs to be configured in Kibana for this to function properly

Check our default fleet example, and our eck-stack example.

@azhurbilo can we get a full set of manifests such that we can easily replicate your setup (pre-upgrade, and post-upgrade preferably) and try and understand the issue? Thanks.
