Docker-freebsd inside jail

[PeterSprague]

Has anyone succeeded in running docker inside a jail? ZFS snapshots, having only data volumes and docker containers that pertain together, isolated from host system, ... ?

I'm experimenting with docker-freebsd on a 10.3 host. The Docker version is considerably behind the Linux current version, but it mostly works on the host. When I attempt to start docker-freebsd installed from pkgs in an iocage jail, it won't start.

Spun up a 11.0-RC2 host, installed linux_base-c7, iocage create debian-jail, debootstrap debian jessie into debian-jail, but Linux version <3.10 as required for docker linux install.

Next option would be to run docker on a Atomic bhyve VM. Anyone experimented with that route? Initial go at getting an Atomic VM spun up was a fail.

Easiest way to get Atomic booted/installed is with bhyve/UEFI, vnc, and a quick run through of the anaconda installer e.g.


# create an empty hard-drive image
truncate -s 20G /images/centos7-atomic-1607.img # or however large you want that to be

# assuming tap0 already setup, and the Atomic iso downloaded from
# http://cloud.centos.org/centos/7/atomic/images/CentOS-Atomic-Host-7.1607-Installer.iso

bhyve \
-c 2 \
-s 0,hostbridge \
-s 3,ahci-cd,/images/CentOS-Atomic-Host-7.1607-Installer.iso \
-s 4,ahci-hd,/images/centos7-atomic-1607.img \
-s 10,virtio-net,tap0 \
-s 11,fbuf,tcp=0.0.0.0:5900,wait \
-s 20,xhci,tablet \
-s 31,lpc \
-l bootrom,/images/BHYVE_UEFI_20160526.fd \
-A -H -m 2G atomic


Remove the 'ahci-cd' line on first boot post-install to force boot off the hard drive.
