Can't resolve host `toolbox` inside `fedora-toolbox:40` container

Open 0rzech opened this issue 1 year ago • 5 comments

Describe the bug

Quarkus application runs fine when started inside fedora-toolbox:39 container. But inside fedora-toolbox:40, a java.net.UnknownHostException: toolbox gets thrown.

Steps how to reproduce the behaviour

  1. Create a fresh F40 toolbox container with toolbox create.
  2. Run sudo dnf install --setopt=install_weak_deps=False java-21-openjdk-devel inside container.
  3. Run quarkus dev or quarkus test inside container.
  4. See the error.

Expected behaviour

Java should not throw the aforementioned exception.

Actual behaviour

Upon starting Quarkus application, the following warning is printed and exception is thrown:

[WARNING] Failed to get hostname, using 'localhost'

The mentioned steps are not enough to reproduce the exact error (requires also installing quarkus), but the java.net.UnknownHostException: toolbox suggests there is some kind of change to the network settings of the toolbox container, not specific to Java/Quarkus.

In the test below, I think we can see the same problem just by using the default programs included in the toolbox image.

fedora-toolbox:39 (works)

There is a difference in how fedora-toolbox:39 and fedora-toolbox:40 set their FQDN hostname, as hostname -f unexpectedly fails in 40. Then, I am using curl just to check the DNS resolution, as the toolbox doesn't have dig/nslookup/etc. Didn't notice any interesting changes to /etc/hosts or /etc/resolv.conf, but there must be something else going on.

There are a number of other Issues/PRs in this repo about DNS and hostname changes, but I'm unclear which could be related or not.

There are some changes to /etc/resolv.conf symlink in #1410, could they be related? I can reproduce this issue on my system -

toolbox version 0.0.99.5

I've been having trouble with X11 programs running in Toolbox containers in Kinoite. The whole KDE desktop (wayland) hangs for several seconds when an X-application (especially Wrye Bash, https://github.com/wrye-bash/wrye-bash, but also vim) opens dialogs or context menus.

Running "sudo hostname localhost" in the toolbox container resolved the issue and X-applications seem to run fine now without hanging the rest of the desktop.

This issue also seems to result in commands such as sudo dnf install ... taking quite a bit longer than expected, likely due to it failing to resolve the hostname. https://github.com/containers/toolbox/pull/1086 has been open for little over two years, but it's seemingly going nowhere.

A workaround is to add 127.0.0.1 toolbox to /etc/hosts on the host, then restart the host network, and restart the container (or recreate it if possible, for good measure). At this point the hostname should resolve just fine.

I am no longer able to reproduce this issue after upgrading to Fedora Silverblue 41 w/ Toolbox v0.1.0. In all cases, the hostname inside the toolbox is reported as toolbx (instead of toolbox previously), and that is resolvable in DNS. Clearly there have been more changes somewhere that impact how hostnames work within the toolbox.

Same as above.
