Docker Daemon Update

[caveman280]

Yeah, I was checking the script worked early to restart it… I’ve just reformatted the image that was mounted to /var/lib/docker/ and restarted the new docker.

Now it reads:
root@MyCloudPR4100 root # ls /var/lib/docker/
btrfs builder containers image network plugins swarm tmp trust volumes

But still getting the:
root@MyCloudPR4100 root # docker run hello-world
Unable to find image ‘hello-world:latest’ locally

@caveman280

jailing process inside rootfs caused \“pivot_root invalid argument\”””

Got it!

Just needed root@MyCloudPR4100 root # export DOCKER_RAMDISK=true

Thank you for your help!!

Any idea on how to make this update persistent on a restart?

[caveman280]

I’ve also got a problem trying to make a service in docker… it appears that vxlan is missing from the kernel so it can’t make the sandbox (the image works find just on the 1 node, but it doesn’t work in a swarm/as a service)
I get the follow error:
"Err": "starting container failed: subnet sandbox join failed for \"172.31.0.0/16\": error creating vxlan interface: operation not supported",

Do you have any ideas how to go about adding vxlan?

I’d like to thank you guys for all the info, it helped me a lot creating my docker package.
Note that the btrfs volume is not necessary, you just need to use the cgroupfs mount scripts and get rid of the devicemapper.
