and the following post:

curl -L -O https://raw.githubusercontent.com/elastic/beats/6.0/deploy/kubernetes/filebeat-kubernetes.yaml

here is full yaml:


I edited variables to point to my instance:

           - name: ELASTICSEARCH_HOST
          value: xxxxxxxxxx.us-central1.gcp.cloud.es.io
        - name: ELASTICSEARCH_PORT
          value: "9243"
        - name: ELASTICSEARCH_USERNAME
          value: elastic
        - name: ELASTICSEARCH_PASSWORD
          value: xxxxxxx

I ran kubectl apply -f filebeat-kubernetes.yaml

and get the following error:

Hi @dinaWork,

Depending on your cluster settings this error may not be fatal. But let me explain what's going on:

We setup RBAC roles to ensure filebeat has access to pods metadata when enriching logs.

While this is what you want, it requires you have the cluster-admin role when deploying it, you can bind this role to your user doing something like this:

kubectl create clusterrolebinding cluster-admin-binding --clusterrole=cluster-admin --user=carlos@elastic.co

Just replace the user name with yours.

It looks like you are trying to use http instead of https, try changing the host value
