Hi, I am using Camunda 8.5 and Openshift. Identity, zeebe gateway, keycloak works as expected but Operate and Tasklist cannot connect to Elasticsearch. But Elasticsearch is available.
I am using Operate configuration like this:
operate:
# Enabled if true, the Operate deployment and its related resources are deployed via a helm release
enabled: true
env:
- name: CAMUNDA_OPERATE_ELASTICSEARCH_URL
value: "http://camunda-platform-elasticsearch-camunda.apps-crc.testing:9200"
# Image configuration to configure the Operate image specifics
image:
# Image.registry can be used to set container image registry.
registry: ""
# Image.repository defines which image repository to use
repository: camunda/operate
# Image.tag can be set to overwrite the global tag, which should be used in that chart
tag: 8.5.3
# Image.pullSecrets can be used to configure image pull secrets https://kubernetes.io/docs/concepts/containers/images/#specifying-imagepullsecrets-on-a-pod
pullSecrets: []
# Logging configuration for the Operate logging. This template will be directly included in the Operate configuration yaml file
logging:
level:
ROOT: INFO
io.camunda.operate: DEBUG
# Service configuration to configure the Operate service.
service:
# Service.type defines the type of the service https://kubernetes.io/docs/concepts/services-networking/service/#publishing-services-service-types
type: ClusterIP
# Service.port defines the port of the service, where the Operate web application will be available
port: 80
# Service.annotations can be used to define annotations, which will be applied to the Operate service
annotations: {}
# Resources configuration to set request and limit configuration for the container https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/#requests-and-limits
resources:
requests:
cpu: 600m
memory: 400Mi
limits:
cpu: 1000m
memory: 1Gi
# ConfigMap configuration which will be applied to the mounted config map.
configMap:
defaultMode: 0444
# ServiceAccount configuration for the service account where the Operate pods are assigned to
serviceAccount:
# ServiceAccount.enabled if true, enables the Operate service account
enabled: true
# ServiceAccount.name can be used to set the name of the Operate service account
name: ""
# ServiceAccount.annotations can be used to set the annotations of the Operate service account
annotations: {}
And this is the error.
