Creating Linux Containers

[ElliotLepley]

Hi there, I noticed that the default CentOS 7 Container doesn't have OpenSSH installed on it by default, and I'd rather like this to be on there. How would I go about creating a new CentOS 7 LXC Container and adding it as a template to my VE Cluster?

Thanks.

Do you use ZFS or LVM-Thin?

Just uncompress the template (it's a compressed tar), chroot into it, change whatever you want (including security updates), exit the chroot and repack the template under a new name that states your changes.

I'm using ZFS.

I'll try that now, thanks! :>

Nice yes... if you use ZFS it is easy to do that. And yes chroot is also an option. How i to that for me?

1. Start you LXC, enter it an change what ever you would like
2. Stop the container
3. Login on the PVEhost and go in containers rootdirectory
4. Delete every temp/cache/history that you not would like to give with
5. Make a package like next line

cd /root/of/the/container
tar -czf /home/iso-images/template/cache/ubuntu-16.04-private-edit_16.04-2_amd64.tar.gz .
