shouldn't the current directory be the default context for "podman build"?
by Robert P. J. Day
"man podman-build" suggests that the context argument is optional:
SYNOPSIS
podman build [options] [context]
podman image build [options] [context]
...
If no context directory is specified, then Podman will assume
the current working directory as the build context, which
should contain the Containerfile.
but if i have a directory with nothing but a Containerfile, i get:
$ podman build
Error: no context directory specified, and no containerfile specified
$
OTOH, specifying context of current directory:
$ podman build .
STEP 1: FROM alpine:latest
... etc etc ...
thoughts?

Problem restarting a mysql container
by Simon Colston
I'm running podman version 1.8.0 on Fedora 31
If I run with this command
podman run --userns=keep-id \
--name=mysql \
--env="MYSQL_ROOT_PASSWORD=mysql" --publish 3306:3306 \
--volume=/home/simon/servers/mysql/var/lib/mysql:/var/lib/mysql:Z
mysql:8.0
I can connect with the mysql client with no errors.
mysql -u root -p -h 127.0.0.1 -P 3306
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
etc.
If I then do:
podman stop mysql
podman start mysql
then I can no longer connect with the mysql client.
mysql -u root -p -h 127.0.0.1 -P 3306
Enter password:
ERROR 2003 (HY000): Can't connect to MySQL server on '127.0.0.1' (111)
I then reset everything:
podman stop mysql
podman rm mysql
and delete all the database files.
If I remove the --userns=keep-id argument I can connect after a 'stop' and a 'start'. (Except that the database files
now have an odd user id that I can only delete as root)
So, --userns=keep-id is the only difference and causing some sort of problem after a restart.
I had this working using podman version 1.7 and I think that (and maybe the kernel) are the only things that have changed.
Am I doing something wrong? Have I found a bug and would you like me to submit it?

max open files
by bryan.hepworth＠gmail.com
Hi all
Some of my users have bumped up against max open files when trying to commit a container image with podman. Does anyone know where this is set in rhel 8.1?
Thanks

httpd install failure
by Seth Kenlon
Since Fedora 31, I can't seem to get a web server to install successfully
into an image. I get failure with Nginx and Apache, and it "feels" like the
failure is probably a post-install action because the RPM gets installed by
dnf, it just ends in failure:
```
$ buildah run centos-working-container-6 dnf install nginx -y
Installed:
[...]
nginx-all-modules-1:1.14.1-9.module_el8.0.0+184+e34fea82.noarch

nginx-mod-mail-1:1.14.1-9.module_el8.0.0+184+e34fea82.x86_64
nginx-mod-stream-1:1.14.1-9.module_el8.0.0+184+e34fea82.x86_64
[...]
Failed:
nginx-1:1.14.1-9.module_el8.0.0+184+e34fea82.x86_64
Error: Transaction failed
```
Installing pretty much anything else works:
```
$ buildah run centos-working-container-6 dnf install lua -y
[...]
Installed:
lua-5.3.4-11.el8.x86_64
Complete!
```
I assume I've forgotten something "obvious" whilst setting up for rootless
containers, or redirecting ports, or something of that nature?

podman & pi, architecture confusion
by Brian Fallik
Hi,
I've been actively following the work to package Podman for Debian for
eventual installation on my raspberry pi nodes. I noticed the installation
docs recommended using the Kubic project packaging and so I used that to
successfully (and easily!) install podman on my raspi. Hooray!
However now I'm having trouble pulling arm images. All my attempts result
in amd64:
# podman pull coredns/coredns:latest
Trying to pull docker.io/coredns/coredns:latest...
Getting image source signatures
Copying blob c6568d217a00 done

# podman image inspect b52ee75a7749d | jq '.[0].Architecture'

and then again with override-arch:
# podman image rm b52ee75a7749d

podman info:
# podman version
Version: 1.8.0
RemoteAPI Version: 1
Go Version: go1.11.6

Any tips on how to convince podman to pull arm images within rasbian?
Thanks in advance,

Rolling updates with Podman
by laurent.pellegrino＠gmail.com
Hi there!
I discovered Podman recently and started to use it as a great alternative to Docker.
My question is about application updates. Let's say you have a pod running and you want to update the code for the app in that pod. Is there a simple manner to manage something similar to a Kubernetes rolling update? By rolling update, I mean performing an update with no service interruptions (i.e. starting a new pod running the new app version, switch the network traffic to the new pod and terminate the old pod).
Kind Regards,
Laurent Pellegrino

Attention any Python Fans
by Daniel Walsh
We are kicking off the Podman-py package to be used for binding against
the new Podman APIV2. We basically have a skeleton at this point, but
we are looking for contributions to help build out the bindings.
Any contributors looking to write python code and ESPECIALLY contribute
tests cases to work with the API, would be greatly appreciated. This is
your chance to get in on the ground floor and start contributing.
Thanks for your consideration.

Podman hanging on start, ps, and erroring out with slirp4netns on run
by Eric Gustavsson
Hi all,
I have unit file generated by podman running, though as soon as I run it
there's issues with running any other command that needs to do something
with containers. podman ps for example will be completely unresponsive and
not return anything, even after waiting minutes. Not only that, but even
running podman start x by itself will hang or creating new containers

Re: podman upgrade from 1.4 to 1.7 on Redhat 7.7
by James Cassell
The packages shipped by Red Hat tend to lag the latest upstream version, almost by design. Last I checked, 1.4.4 was the latest available in RHEL 7.
V/r,
James Cassell
