Version: 2.1.1+dfsg1-3<br>
Severity: wishlist<br>
<br>
When running stuff that was originally written for docker, image names<br>
will usually be provided in their short form, i.e. debian:10,<br>
fedora:rawhide. In the current state of the Debian packaging, those will<br>
fail like this:<br>
<br>
$ cat Containerfile<br>
FROM debian<br>
$ podman build -t foobar .<br>
STEP 1: FROM debian<br>
Error: error creating build container: (image name "debian" is a short name and no search registries are defined in /etc/containers/registries.conf): while pulling "debian" as "localhost/debian": Error initializing source docker://localhost/debian:latest: error pinging docker registry localhost: Get "<a href="https://localhost/v2/" rel="noreferrer" target="_blank">https://localhost/v2/</a>": dial tcp [::1]:443: connect: connection refused<br>
<br>
On Fedora, on the other hand, this just works, because their<br>
registries.conf provides by default a list of as few registries<br>
registries where to look up unqualified image names:<br>
<br>
[terceiro@fedora tmp]$ grep -v '^#' /etc/containers/registries.conf<br>
unqualified-search-registries = ['<a href="http://registry.fedoraproject.org" rel="noreferrer" target="_blank">registry.fedoraproject.org</a>', '<a href="http://registry.access.redhat.com" rel="noreferrer" target="_blank">registry.access.redhat.com</a>', '<a href="http://registry.centos.org" rel="noreferrer" target="_blank">registry.centos.org</a>', '<a href="http://docker.io" rel="noreferrer" target="_blank">docker.io</a>']<br>
<br>
I don't think we want to include the fedora/redhat/centos registries,<br>
but we should include at least the <a href="http://docker.io" rel="noreferrer" target="_blank">docker.io</a> registry, which is the _de<br>
facto_ standard in the container world at the moment. So can we please<br>
provide something like the line below by default in<br>
/etc/containers/registries.conf?<br>
<br>
unqualified-search-registries = ['<a href="http://docker.io" rel="noreferrer" target="_blank">docker.io</a>']<br>
