Hi community,I have a microservice written in `Go` deployed on both GKE and EKS that basically fetches the container log, parses it, do some modification, and then saves it to database.

The problem is that it is working on AWS but not on GKE. I looked into the cluster and found that `GKE` uses `containerd` runtime while `AWS` has `docker` runtime.Log formatting of these runtimes are different.

Containerd runtime format:

2021-06-22T10:27:25.813799277Z stdout F some log

Docker runtime format ( JSON ) :

{“log”:“some log\n”,“stream”:“stdout”,“time”:“2021-06-22T10:27:25.813799277Z”}

Due to this issue, my service is not able to parse the logs coming from containers from `containerd` runtime.  
I tried custom function to parse the containerd log to docker json log format but it doesn’t help.Is there any way to fix this issue programmatically using `Go` ? Thanks!
