Sure there is such a thing. It's a tiled console package (tilix is
what I use). In all honesty, I wouldn't want Libreoffice running in
a container and I can't imagine why you'd want an xterm in its own
container. Most containers I've built have been RESTful API
containers, NGINX proxies/web servers, etc. I spend more time on the
container host making changes, than in the containers themselves. If
an API change has been made, I throw a new container up with that
change and test, rarely, if ever, do I need access the container
directly. And that's the idea behind containers if you ask me.
Lots of people think of containers being for servers, as you say. It's
what
Docker lives off, and really does feel like the focus of Docker.
Singularity lets you think somewhat differently, and has proved very
useful in
areas like HPC, where you want to let a user bring a software
environment to a
machine. You get people like OpenFOAM releasing their software as a
Docker
container:
https://openfoam.org/download/4-1-linux/
I've also used it to run Ubuntu packaged software on CentOS without
having to
jump through hoops trying to repackage it or otherwise rebuild a million
dependencies in just the right way.
I honestly had forgotten about Singularity. Mainly because it's been a
couple of years since I managed any HPC equipment. But seriously, I
think of containers the same way I do linux tools. Unlike MS, a linux
does does one thing, and that thing very well, whereas MS has tried to
be everything to everyone and is so-so at all of them. Perhaps that was
the original intention of container and it's morphed into something else
over time, which, if true, means I need to adjust how I define it rather
than trying to beat that square peg into the round hole in my head.
On a side note, as I write this, Pandora decided to toss
'Misunderstading' by Phil Collins into my playlist. It's playing as I
type. Go figure.
