podman on FreeBSD
by Doug Rabson 16 Aug '22

16 Aug '22

Over the last few months, I have been working on porting the github.com/containers tool stack to FreeBSD, using the FreeBSD jail subsystem for isolation. This builds on Samuel Karp's earlier work on runj, which is a jail-based OCI runtime. Since buildah v1.27.0 contains working FreeBSD support for building container images and it looks like this will be vendored into podman quite soon, I would like to get the much larger set of changes for podman on FreeBSD into review somehow. The complete set of FreeBSD changes is much too large for a single PR, so I'm going to try to take this one file at a time. My plan is approximately: 1. Add enough stubs to libpod to make it compile on FreeBSD (without working at all) 2. Pick a file from libpod/*_freebsd.go, ideally with the smallest set of cross dependencies and make a PR which adds the freebsd file and in a small stack of commits, factors out as much as possible of the shared code between linux and freebsd. 3. Work through review as normal until the PR can be merged. 4. Go to step 2 unless I'm done. Does this seem reasonable? It's going to take a while - my working branch has 21 freebsd files with varying degrees of complexity. Doug.

August 18, 2022 Podman Community Cabal Meeting - Canceled
by Tom Sweeney 15 Aug '22

15 Aug '22

Hi All, The Podman Community Cabal Meeting scheduled for this Thursday August 18, 2022 at 11:00 a.m. EDT (UTC-4) has been canceled. We recently realized that most of the attendees will be attending DevConf.US at that time. DevConf.US is free to attend, and you can do so in person or virtually. The only requirement is you need to sign up and you can do so for free at https://www.devconf.info/us/. A bunch of info there too on the times and topics. FWIW, Dan Walsh will be doing the Keynote on Saturday August 20, 2022 at 9:30 a.m. EDT (UTC-4). Our next Podman Community Cabal meeting will be on Thursday September 15, 2022 at 11:00 a.m. EDT (UTC-4). Thanks All! t
