CentOS 7 /etc/hosts vs /etc/cloud/templates/hosts.*.tmpl?
If I create a CentOS 7 droplet using the default DO-supplied image, I note when going to /etc/hosts to add private IP aliases for my other droplets that there’s this:
# Your system has configured 'manage_etc_hosts' as True. # As a result, if you wish for changes to this file to persist # then you will need to either # a.) make changes to the master file in /etc/cloud/templates/hosts.redhat.tmpl # b.) change or remove the value of 'manage_etc_hosts' in # /etc/cloud/cloud.cfg or cloud-config from user-data
If I look at
/etc/cloud/templates/ I see three
hosts.OSflaver.tmpl files: debian, redhat, and suse. I tried adding my aliases to all three not knowing/caring which is being sourced and rebooted the droplet. Nothing.
I add the entries directly to
/etc/hosts and reboot, they stick despite the warning.
/etc/cloud/cloud.cfg reveals some DigitalOcean configuration? Not sure if I need to or should attempt to disable
manage_etc_hosts as suggested in the
hosts comments, figure out how to use the templates, or what?
Anyone have any advice? For now I’m just using
/etc/hosts and ignoring the warning comments. So far it seems okay but it’s likely not.
