YUM not working inside amazonlinux container running on a Ubuntu host

Question

While trying to do a `yum install wget` inside the amazonlinux docker container running on ubuntu, it is failing with the following logs:

```
r&region=unknown: [Errno 12] Timeout on https://cdn.amazonlinux.com/2/core/2.0/x86_64/60218a287b1e04d5b93212019453c3417aa7bc4d1df7895e7c4abfd1e6d824a7/repodata/repomd.xml?instance_id=URLError&region=unknown: (28, 'Resolving timed out after 5000 milliseconds')
2022-09-19 17:37:05,172:[prepare]:[ERROR]:: #5 23.95 Trying other mirror.
```

There is internet connection inside the container, as I am able to `curl www.google.com` and get a successful response.

Not sure if there is a proxy issue happening here but perhaps see this to get some pointers for "Resolving timed out after 5000 milliseconds". It does not have use case of  amazonlinux container running but perhaps can provide some pointers to troubleshoot
