[Bug]: The /etc/hosts file is not created by default

[afbjorklund]

I have done the following

• I have searched the existing issues
• If possible, I've reproduced the issue using the 'main' branch of this project

Steps to reproduce

I am missing entries for localhost and hostname, in the newly created container.

Current behavior

The /etc/hosts file is missing.

/ # hostname -i
hostname: 265508e3-df31-4cc4-9668-2ac902e1075a: Host not found

Expected behavior

The /etc/hosts to be created.

/ # hostname -i
192.168.105.185

Environment

- OS: 15.5
- Xcode: 16.4
- Container: 0.2.0

Relevant log output

We definitely should expose a knob in containerization to set this up (ideally it should be able to setup any arbitrary entries in /etc/hosts you may want as well). And then we can use the bits over here.

[afbjorklund]

Here is my workaround, after container creation:

# echo "127.0.0.1 localhost" >/etc/hosts
# echo "$(/sbin/ip -o -4 addr list eth0 | awk '{print $4}' | cut -d/ -f1) $(hostname)" >>/etc/hosts

You might want to add an entry for host.docker.internal host.containers.internal (i.e. the host), as well?
