[ale] Containers... use?

[Jeff Layton]

I use containers all the time for the day job and I use them a little at home. The day job is mostly Docker. It's really great and easy to use but the root access issue still bugs me.
I also use Singularity and it's great! Easy to install, use, and make containers. I use a little at work but more so at home. It allows me to create a container for some applications and then move them around my systems as needed.
YMMV.

I use cgroups, namespaces, and chroots all the time. Daily.  Constantly.
 Right now.  I've only played with docker.

They are single use processes. No shells. No sshd.  No patching.
Limited access to most of the hostOS file system.

Is that a "container"?

I would use containers for internal software development and deployment.
I'm not ready to place them on the internet at this point. If I allowed
php webapps to be internet facing, I'd run each of them in a container
with nothing else, so WHEN they are hacked, there isn't enough of an OS
there to have a shell, no editor, and do anything except run the webapp.
