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?

Making progress running MTA container - Q re ports
by Philip Rhoades
People,
Starting my MTA with:
podman run --rm -d -h pricom.com.au \
-v /home:/home \
-p 127.0.0.1:25:25 \
-p 127.0.0.1:143:143 \
-p 127.0.0.1:587:587 \
-p 127.0.0.1:993:993 \
-p 127.0.0.1:995:995 \
--name indimail \
`podman images | grep indimail | awk '{ print $3 }'` \
indimail
- works happily and while mail delivery is working fine within the
container, the ports are not accessible from other computers ie:
I have opened ports on the host using iptables and when using nmap on
localhost get:
Starting Nmap 7.80 ( https://nmap.org ) at 2020-03-27 13:47 AEDT
Nmap scan report for localhost (127.0.0.1)
Host is up (0.0000050s latency).
rDNS record for 127.0.0.1: localhost.localdomain
Not shown: 993 closed ports
PORT STATE SERVICE
22/tcp open ssh
25/tcp filtered smtp
143/tcp filtered imap
587/tcp filtered submission
631/tcp open ipp
993/tcp filtered imaps
995/tcp filtered pop3s
- which doesn't look promising and from another machine on the LAN I
get:
Starting Nmap 7.80 ( https://nmap.org ) at 2020-03-27 13:44 AEDT
Nmap scan report for phil (192.168.1.20)
Host is up (0.00019s latency).
rDNS record for 192.168.1.20: phil.pricom.com.au
Not shown: 994 filtered ports
PORT STATE SERVICE
22/tcp open ssh
25/tcp closed smtp
143/tcp closed imap
587/tcp closed submission
993/tcp closed imaps
995/tcp closed pop3s
- so I must still missing something about linking container ports to the
same host ports . .
Suggestions?
Thanks,
Phil.

libpod - python integration testing
by Damon Hatchett
Hi,
I am interested in running python integration tests and/or
anything particularly useful for the group. I checked out apiv2: test using
docker-py integration tests #5386
<https://github.com/containers/libpod/issues/5386> and am trying to
replicate the docker API tests - suitable for podman. Dont know if someone
else all over this or not. ATM I am just tying to replicate
ListContainersTest (docker-py
<https://github.com/docker/docker-py>/api_container_test.py...
"import docker"..."import podman") a simple container list test, but
breaking here (leads almost to next question, any heads up on status of
Python API appreciated). eg
api_container_test.py:
>>> import os
>>> import re
>>> import signal
>>> import tempfile
>>> import threading
>>> from datetime import datetime
>>>
>>> import pytest
>>> import requests
>>> import six
>>> import docker
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'docker'
>>> import podman
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'podman'
>>>
Cheers!

Error: timed out waiting for file /var/run/libpod/exits/. . .: internal libpod error
by Philip Rhoades
People,
I am making progress with the Podman MTA mentioned in the previous
emails (thanks for the help!) - however, I have noticed these errors a
few times as I fix / change things and rebuild the image and container:
# podman stop indimail
2020-03-24T22:23:00.000955080Z: error opening file
'/run/user/0/crun/e75c80ad2b9dc7a79110614459158d1e48cda2c7cabccad64570ea1f91532a24/status':
No such file or directory
Error: timed out waiting for file
/var/run/libpod/exits/e75c80ad2b9dc7a79110614459158d1e48cda2c7cabccad64570ea1f91532a24:
internal libpod error
- I am not sure but I think on some of the occasions the stop command
has not worked and I have had use a more drastic approach . .
What should I be looking for to address this issue?
Thanks,
Phil.

2 Questions re a Container having access to the Host's file system
by Philip Rhoades
People,
I want to have a MTA running from a container but is it possible for the
containerised MTA:
1. to deliver mails to users on the host's file system dir (eg
/home/user/Maildir)?
2. to have access to the host's:
/etc/passwd
/etc/shadow
/etc/group
/etc/gshadow
files for users who are logging in to the host to look at their mails?
Thanks,
Phil.

Anyone got ZeroTier working in podman containers?
by Philip Rhoades
People,
I am just starting to make real use of podman containers but, for one
particular exercise, it would be convenient if I could use zerotier in
one of the containers but I get:
[root@1c15d54fa274 /]# zerotier-cli info
zerotier-cli: missing port and zerotier-one.port not found in
/var/lib/zerotier-one
- it works for other, non-container, devices - as well as VMs on KVM.
Thanks,
Phil.
