sed command for /etc/hosts about isle HOT 7 CLOSED

@hamhpc I like the thinking here.

Tested the command locally:

Output after running command:

sed: 1: "/etc/hosts": extra characters at the end of h command

End result: (updated /etc/hosts file)

127.0.0.1 localhost
#127.0.0.1 localhost islandora-docker.com fedora web fedora.islandora-docker.com web.islandora-docker.com
255.255.255.255 broadcasthost

Does this look correct to you? @hamhpc

actually it doesn't. The logic here is to find the match for the first line:

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4

and replace it with the same line followed by a carriage return and the second line containing the isle host info. I think the tricky part here is that I think there needs to be a tab in the line and a copy paste might not copy properly. You can look at: https://github.com/hamhpc/ISLE-ks/blob/master/ks_ISLE.cfg for the version I'm using and appears to work when running it via kickstart.

The only issue is that the first line looks like this for CentOS:

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4

But I'm not sure it's the same convention for other OS's so that might need to be handled.

@hamhpc @McFateM @br2490 I've not heard back on how to advance with this command. Wondering if still needed given in isle.localdomain we use the extra_hosts: command to give the containers the appropriate DNS resolution. @br2490 Does this match your experience during your community alpha?

@g7morris, yes my experience in Alpha2.

I'll add I've also had success using separately defined docker networks - I'm behind on my pre-alpha-alpha (Barnard was set for Feb, I jumped the gun) testing so hopefully by Monday I have something more meaningful to say.

I think there are several ways to accomplish this and extra_hosts is probably the fastest. I'd still like to investigate separate docker networks, one internal (all containers sit on this), and one external (such that only outward facing containers go here, i.e.: isle-apache).

@hamhpc in trying to keep with Docker practice we try to avoid editing the host file directly and let docker handle it. Gavin mentions extra_hosts which adds an unlimited number of entries into hosts, I'll mention hostname and domainname params too, but I fail to remember if compose respects them. knowing compose, it's like a 50/50.

edit, specifying which alpha.
