Alternative to LXD for Fedora?

I want to start by saying I LOVE LXD a lot. So much so, that I want to get a similar alternative on Fedora/CentOS/OpenSUSE since I prefer the RPM side of Linux. I know there's LXC (since LXD is really just a glitter-packed and easy LXC as I understand), but I also realize LXC/LXD containers aren't all that portable, which is why Docker is neat. However, I don't see anywhere in the use of Docker where I can drop into a BASH shell and pretty much have the same functionality as my host machine as you would in LXD. I also prefer containers because they're lighter packages. Does something like this exist? I like the thought of Docker, but I don't see it offering as much granular control. I'm kinda newb to the container stuff too so pardon my ignorance in my question and if I'm misunderstanding things

Docker isn't the same thing as LXD. Docker is for packaging applications, while LXD is for packaging virtual machines. Each has its place in the greater scheme of things.

Re: Alternative to LXD for Fedora?

I know, and LXD doesn't create VMs either, they are still containers. I'm just under the impression that Docker doesn't give you as much control over what you create since, as far as I'm aware, I can't run bash in a Docker container and install packages, do WGETs, etc. to create my container. I'm just interested in something that has similar portability to Docker but gives me more control than what I see Docker providing

What's wrong with just a bare LXC?

There is also systemd-machined that can run pretty much anything.

Re: Alternative to LXD for Fedora?

Nothing really wrong with LXC, I just found using LXD is a lot cleaner. I'll look into systemd-machined. I have continually been curious about rkt as of late, but I don't see a tiddle of information on creating images anymore than a "hello world" container

Re: Alternative to LXD for Fedora?

Not sure if you are aware of it, there's a copr repo available for LXD: https://copr.fedorainfracloud.org/coprs/ganto/lxd/

You can try it by enabling it "sudo dnf copr enable ganto/lxd" and then following instructions from the copr page. Install instructions starts with "setenforce permissive", though.

Re: Alternative to LXD for Fedora?

I managed to make myself comfortable with LXC for now, but my hope is for LXD some day. I did a lot of digging and found LXD currently only works with AppArmor profiles (hence disabling SELinux). Linux Containers (and as a result, LXD) relies a lot on Linux kernel namespaces for their segregation and LSM for more necessary security. Because of that, I don't think I would run LXD on any distro other than Ubuntu. I also like how LXD is set up out of the box, though you could do similar stuff to LXD. There is talk about SELinux support for LXD in the future so I will wait for that and use LXC on redhat distros or LXD on ubuntu (and soon Debian!) Thank you for your help srakitnican

My 0.02$:

personally, if I would find a way to delete SElinux from the kernel, I would.

Re: Alternative to LXD for Fedora?

Not a smart idea at all. Especially with containers. In today's age, LSM is highly important
