Hi,
I am using the docker community version 20.10.6 in my environment. I also have a docker swarm in that I have deployed my Jenkins docker service. I have customized the Jenkins image to use the local docker within the Jenkins docker container. So whenever I run the pipeline my pipeline will build the application docker images. So now for the past 2-3 days, I am observed that from multiple servers I am seeing some random docker build failures and showing errors like unknown parent image ID sha256:<Intermediate container SHA Value> or failed to export image: failed to set parent sha256:<Intermediate SHA value>: unknown parent image ID:<Intermediate SHA value>
So not really sure what’s happening and we did not change any docker version recently. So can anyone please help me dig deep more about this.?
Based on my observation I see it’s happening only at multiple copy commands in docker files.
