Today, systemd is included with our 7.2 and newer base images. We are putting the finishing touches on the work Colin started earlier this year and plan to release a new, minimal base image. I've been toying with the name rhel7-core, but that name sucks and will likely change. Since the new minimal

There has been a lot of talk of also doing this with VFS back end also (Which is basically standard storage). One of our long term goals with OCID is to support readonly containers on an NFS store. Which would also give us the same benefits over a COW file system. On 10/26/2016 02:20 PM, Vish

​If a user specifies read-only in their podspec...what does that translate to (it might be a distro-specific question). IMO the --shared-rootfs should be the default when --read-only is specified, but it's not atm. Vivek has implemented it for devicemapper first. But the intent is that it will b

IMO, this doesn't really need any new knobs in the pod spec. This could be handled under the hood in the container runtime level (by config or default). On Wed, Oct 26, 2016 at 11:44 AM, Jeremy Eder wrote: > ​If a user specifies read-only in their podspec...what does that translate > to (it mig

Yeah it sounds like it - that's a good place to start, and then if we realize we need the knob we can come back and decide on an API object change if necessary. On Wed, Oct 26, 2016 at 2:46 PM, Mrunal Patel wrote: > IMO, this doesn't really need any new knobs in the pod spec. This could be > han

The advantage of setting up a layered image called RHEL7-systemd on top of RHEL7 is that we could default the two things necessary to run a systemd container. STOPCMD and CMD. Also we could continue to work to get systemd out of the RHEL7 base container. On 10/26/2016 02:36 PM, Ben Breard wrote:
