containers
when container is run with a network hosts search domains are ignored
on host
mphillips81@mmp-pw-dev ~/repos/ose (main)✗ % cat /etc/resolv.conf
options attempts:1 timeout:2
search foo.com bar.com
on podman:
mphillips81@mmp-pw-dev ~/repos/ose (main)✗ % docker run -it --network=ose_default obfuscated.com/rhel7-dpkg:latest /bin/sh
sh-4.2# cat /etc/resolv.conf
search dns.podman
nameserver 10.89.4.1
options attempts:1 timeout:2
sh-4.2# exit
mphillips81@mmp-pw-dev ~/repos/ose (main)✗ % docker run -it obfuscated.com/rhel7-dpkg:latest /bin/sh
sh-4.2# cat /etc/resolv.conf
search foo.com bar.com
nameserver 10.0.2.3
nameserver 10.10.10.10
nameserver 10.10.10.11
options attempts:1 timeout:2
sh-4.2# exit
sorry for the obfuscated bits, it should be reproducible with any image. when run via docker the search domains are maintained as expected, both with and without network. I'm not sure if this is the right repo to file an issue, please redirect me if not. thank you!
forgot to mention this was tested/verified with
mphillips81-dev-mse.pw1.bcc.bloomberg.com /root # podman version
Client: Podman Engine
Version: 4.9.4-rhel
API Version: 4.9.4-rhel
Go Version: go1.21.11 (Red Hat 1.21.11-1.el9_4)
Built: Thu Aug 8 08:51:41 2024
OS/Arch: linux/amd64
this may have been fixed in a newer version, i dont have a means to easily verify that at the moment
Its not fixed and it is a podman issue. Netavark has no knowledge of the current search domains. We just return dns.podman as we use that for aardvark-dns but it is up to podman to append the other entries if this what the correct behavior should be.
