This fails for me on xenial after upgrading from Docker v1.13.1 to 17.03.2-ce from xenial-proposed. Here's what I did:
1. Deploy a Canonical Distribution of Kubernetes cluster (which deploys worker instances with Xenial and gets Docker v1.13.1 via `apt install docker.io`) 2. On all worker units: add xenial-proposed line to sources.list.d, then `apt update && apt install docker.io` 3. Run `docker --version` on the worker units to confirm 17.03.2-ce was installed. At this point, I observed that Kubernetes could no longer create containers, with errors coming from Docker along these lines: Create container failed with error: invalid header field value \"oci runtime error: container_linux.go:247: starting container process caused \\\"process_linux.go:334: running prestart hook 0 caused \\\\\\\"fork/exec /usr/bin/dockerd (deleted): no such file or directory\\\\\\\"\\\"\\n\" After observing this failure repeating for several minutes, I did the following: 4. On all worker units: `service docker restart` This fixed the problem: the fork/exec errors from Docker stopped, and Kubernetes was able to create containers again. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1732368 Title: upgrade to 17.03.2-ce in 16.04+ To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/docker.io/+bug/1732368/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
