Hi, In order to use TestContainer framework, I need to use the new REST API. Does io.podman linux daemon provide the service ? Regards.

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. -- Philip Rhoades PO Box 896 Cowra NSW 2794 Australia E-mail: phil(a)pricom.com.au

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! -- DAMON HATCHETT CONSULTANT Red Hat ACT <https://www.redhat.com/> Level 11, Canberra House 40 Marcus Clarke Street dhatchet(a)redhat.com M: +61422276484 <https://red.ht/sig> @RedHat <https://twitter.com/redhat> Red Hat <https://www.linkedin.com/company/red-hat> Red Hat <https://www.facebook.com/RedHatInc>

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. -- Philip Rhoades PO Box 896 Cowra NSW 2794 Australia E-mail: phil(a)pricom.com.au

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?

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.
