Docker in Docker Image fails to creating aufs mount after Concourse v3.0.1 #1351
What challenge are you facing?
I have a job that would run server tests in a docker in docker image which creates a docker compose stack to run the necessary containers. The job can be seen below
This job was working fine on concourse v3.0.1. After that version it will fail to build the aufs mount when the job starts. A snippet of error can be seen below
I suspect it is the change in v3.1.0 where the filesystem uses overlay rather than btrfs. I am not 100% sure but any version of concourse from 3.1.0 and onwards does not work anymore.
Reproducing the issue
While my job is quite specific, if you want to see a general issue, run the following job
Running the image registry:2 will fail to pull down the image.
If anyone can give some insight to the problem that would be great. I can stick to 3.0.1 for now, but there are some really nice features from later versions I would like to use.
Here's the output of our build after performing the change:
and so on. Any idea of why docker is not coming up with the new
@gabro your setup might be different from mine, i'm using this Dockerfile https://github.com/recordunion/RU.PublicDockerfiles/tree/master/concourse-dcind and it works just fine with 3.2.1. you can try mine just to isolate your problem
