how a container access another container
by Abdul Shaik 06 Nov '21

Hi, there. I've a question regarding containers using podman. I've a database in one container. Let's call it 'Container 01' And I want other containers to access the database in the 'Container 01'. Is that possible? If so, would you please let me know? Thanks in advance. Best regards.

Support for WireGuard interface and multiple network interfaces
by Maximilian Ehlers 05 Nov '21

05 Nov '21

Helo everyone, for a while I have been using containers that join themselves into a VPN via their entrypoint script. Only a small CIDR is forwarded to that private network and all other traffic gets routed over the bridged network via the host. In my exact use case the containers use WireGuard and need the following configurations: - private key (public keys can be derived) - public key of an endpoint - network routable IP of an endpoint - Port of the endpoint - CIDR to route to endpoint Optionally multiple endpoints could be specified. As this hack inside the entrypoint is not the most elegant way (DRY) and so on, I would like to ask whether or not it would be possible to integrate this functionality into podman. Specifically to integrate support for a WireGuard interface configurable via CLI flags/config && together with this giving a container multiple network interfaces at spawn with the ability to specify which CIDR should route to which interface. Implementing this would be an interesting challenge for me if it is at all possible (or am I wasting my time here?)/ Any hints as to how I could proceed in implementing and testing this in a fork of the project would be much appreciated! Thanks alot Max <b-m-f>

migrating from docker to podman: SELinux labels
by Tom Deseyn 04 Nov '21

04 Nov '21

Hi friends of podman! I'm updating an application that uses docker to work with podman on Fedora. I run into the issue that the volumes are not accessible in the container. I can make it work by adding the 'z' option to place the proper labels on the content. Is this the right way to go about it? The docker documentation has some warnings ('use extreme caution') for these options. This is not mentioned in the podman docs. Does it work differently between podman and docker, so that the warning wouldn't apply to podman? Thanks, Tom

Podman Community Cabal Meeting Time Change and Podman Community Meeting reminder
by Tom Sweeney 29 Oct '21

29 Oct '21

Hi All, Just a quick note on a couple of meeting updates. The Podman Community Cabal Meetings have been happening at 10:00 a.m. EDT (UTC-4) on the third Thursday of each month. Due to a conflicting meeting for a number of the key maintainers, we have decided to move the meeting from 10:00 a.m. to 11:00 a.m. EDT, still on the third Thursday of the month. Secondly, the next Podman Community Meeting snuck up on me and is happening this coming Tuesday November 2, 2021 at 11:00 a.m. EDT (UTC-4). We don't have a lot of topics for next week, so if you have something you'd like to present, or a topic that you'd like to hear about, please drop me a note. Thanks All! t

is podman (and friends) reasonably complete under recent ubuntu?
by Robert P. J. Day 27 Oct '21

27 Oct '21

current colleague wants to set up as complete a podman-based environment as possible, and corporate policy dictates must be ubuntu, but can be as recent an ubuntu version as desired (even brand new 21.10). predictably, i suggested fedora would be a better choice, but that's not an option given corporate choice of ubuntu for dev boxes. so the question is, will that still provide a reasonably complete set of container tools relative to fedora using just standard packages? rday

How to setup internal and external networking for rootless containers with podman
by Gerben Venekamp 27 Oct '21

27 Oct '21

I am trying to setup networking in rootless containers. What I would like to have is both internal, i.e. container to container, and external, e.g. ping 8.8.8.8, inside a single container. I get internal working as well as external, however never both at the same time within a single container. I have raised this question on stackoverflow as well. The question on stackoverflow can be found at: https://stackoverflow.com/questions/69636101/how-to-setup-internal-and-exte… Regards, Gerben

Q: Slightly uncomplicating manifest-lists
by Chris Evich 21 Oct '21

21 Oct '21

All, Recently I wrote a blog article that touches on a few podman (and buildah) commands which are bound to catch people off-guard: https://podman.io/blogs/2021/10/11/multiarch.html Unfortunately the reason for the "Ugh! What? Really?" of 'rm' and 'push' is "maintaining compatibility" - hence, unlikely to change. See https://github.com/containers/podman/issues/11899 So my thinking was, if we can't change the CLI can we make the feedback to users better? At least then, people would be alerted when it comes to surprising 'rm'/'push' behavior. For example: $ podman images REPOSITORY TAG IMAGE ID CREATED SIZE docker.io/library/redis latest 7faaec683238 7 days 116 MB reg.fed.org/fedora 34 191682d67252 2 weeks 184 MB ex.co/foo/bar latest [M]123456576b54 1 second 123 GB reg.acc.red.c/ubi8-init latest 670b0e87da3c 4 weeks 251 MB quay.io/libpod/alpine latest 961769676411 2 years 5.85 MB Indicating 'ex.co/foo/bar' is a manifest list not a regular image, and so needs special handling by the user. Alternatively it could be it's own column. I was just wanted to be sensitive to anyone who may be scraping the space-separated data for some purpose. What are your opinions/concerns/alternatives for something like this? -- Chris Evich (he/him), RHCA III Senior Quality Assurance Engineer My personal robot overlord told me to include this signature line.
