Docker sometimes fails on Debian 9


(Mbloore) #1

Docker sometimes fails to start up on my Google Compute Engine Debian 9 VM.
Docker version 17.05.0-ce, build 89658be
Linux main 4.9.0-5-amd64 #1 SMP Debian 4.9.65-3+deb9u2 (2018-01-04) x86_64 GNU/Linux

Sometimes when I start the VM Docker is fine. Sometimes not. In that case the easy way to tell is to use docker images and if none are listed then nothing will work properly. For example

$ docker run hello-world
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
ca4f61b1923c: Pull complete 
Digest: 
sha256:97ce6fa4b6cdc0790cda65fe7290b74cfebd9fa0c9b8c38e979330d547d22ce1
Status: Downloaded newer image for hello-world:latest
docker: Error response from daemon: failed to update store for object type 
*libnetwork.endpointCnt: Key not found in store.
ERRO[0001] error getting events from daemon: net/http: request canceled 

In that case the pull actually did work. But pulling my own images doesn’t, and gives odd messages. I haven’t had any luck Googling for that message. Others seem to have similar problems, though.

When startup fails the status looks like this:

# systemctl status docker.service

Can anyone help me figure out what is going on? Thanks.
