Docker complains about invalid certificate after update to v1.7.0


After updating to Docker v1.7.0 (and also boot2docker), I'm getting the following error when running docker ps:

x509: certificate is valid for 127.0.0.1, 10.0.2.15, not 192.168.59.103

Is this a known issue with this version, and what can I do to fix this?


Solution

  • This is a known issue introduced in version 1.7.0 of boot2docker: https://github.com/boot2docker/boot2docker/issues/824

    Update to boot2docker 1.7.1

    Updating to boot2docker 1.7.1 fixes this issue, as described here.

    Options for boot2docker 1.7.0

    It seems to be related to the way the network interfaces are coming up during boot. The following options can be used to fix this.

    Option 1

    The fix is to run the following sequence, which adds code to wait for all network interfaces to be present:

    boot2docker ssh
    sudo curl -o /var/lib/boot2docker/profile https://gist.githubusercontent.com/garthk/d5a17007c277aa5c76de/raw/3d09c77aae38b4f2809d504784965f5a16f2de4c/profile
    sudo halt
    boot2docker up
    

    Source (and more details on the code that is downloaded): https://gist.github.com/garthk/d5a17007c277aa5c76de

    This has fixed the issue for me, although I had to stop the boot2docker-vm through the VirtualBox UI to get a clean start.

    The Gist adds the following to the .profile file in the boot2docker VM:

    wait4eth1() {
            CNT=0
            until ip a show eth1 | grep -q UP
            do
                    [ $((CNT++)) -gt 60 ] && break || sleep 1
            done
            sleep 1
    }
    wait4eth1
    

    This function waits up to 1 minute for the eth1 interface to come up.

    Option 2

    Another option seems to be to do

    boot2docker delete
    boot2docker init
    boot2docker up
    

    This will destroy the boot2docker VM - you might lose any customizations you have done.
