In case you don't must capture the logs from within the same pod as your containers, you can use ECK's Filebeat Kubernetes operator to automatically set up pods that ships containers logs to Elasticsearch. Read the documentation of ECK here:https://www.elastic.co/guide/en/cloud-on-k8s/current/index.html
