docker ERROR: unknown blob

Question

On launching app using docker getting message ERROR: unknown blob as per

docker-compose  -f /usr/local/tmp/khufu01/loud_deploy/nokube/dind/dock         


        

Answer 1

In my case removing /var/lib/docker made things worse - pulling failed with

$ docker-compose up -d
Pulling mysql-service (mysql:5.7.17)...
5.7.17: Pulling from library/mysql

ERROR: open /var/lib/docker/tmp/GetImageBlob310458906: no such file or directory

Purging docker solved the problem.

Answer 2

Solution : ERROR: unknown blob is trying to say the image is not found

... this makes sense since earlier today all local docker images were deleted

So after building the missing image the docker-compose up ran fine
