Debian MIPS images about lxc-ci

[stgraber]

Not very easily, no. The CI infrastructure that builds those images runs on the native architecture (see jenkins.linuxcontainers.org). We do have fast builders for all the other architectures, but not for any of the mips stuff.

Ah I didn't know everything was built natively. Using QEMU works (the -I option to the lxc-debian template), but if that's not good enough I don't think there are any options left.

[stgraber]

Yeah, this may be a bit tricky to do even with a VM because we need to setup a full Jenkins builder in there and I'm not sure what kind of performance we'd be getting from running the big Jenkins java runner inside such a VM :)

[jcowgill]

I mean qemu-user. You install it on the host and then pass -I /usr/bin/qemu-mips64el-static (or something similar) to lxc-create and it will use qemu to build the image.

[stgraber]

Ah yeah, we could add support for qemu-user-static to the lxc-ci code and then have it build using the two stage --foreign debootstrap option that lxc-debian already supports.

[stgraber]

Closing this here as we're entirely relying on distrobuilder for image building now.
If you want to contribute qemu-user-static support to distrobuilder for Debian images, then we could add the MIPS images.

@jcowgill , do you have any progress here?
