From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

If that's the case then it means there's no networking configured for the container or inside it. The image you're using may not come with DHCP enabled or networking at all.
You are. You aren't supposed to SSH into a container... it's just a waste of time. Simply run:
And you'll inside the container much faster and without wasting resources.
But that then leaves me as root, is there a way to just have a normal user? Or is that also not really intended?
Well, it's a container, in most situations you would be running as root because the root inside the container is an unprivileged user outside it. So in effect the root inside the container will only be able to act as root inside that container and nowhere else. Most people simply do it that way and don't bother with it.
If you really want there are ways to specify the user... but again there's little to no point there.
For your convenience you can alias that in your host's
~/.bashrcwith something like:And then run like:
I guess that does make sense. Part of what I had in mind was having different instance for different projects. I guess in my mind it gives me a reason to have and practice multiple as well as feeling cleaner (keeping compiler and stuff off host). I will try out your advice when I get home. Thank you so much!
I use LXD (too lazy to move to Incus at the moment) for this exact purpose. It’s definitely nice having a greater degree of isolation between the various projects I’m working on — especially when working with confidential information from clients. Depending on what you’re looking to do there are simpler ways to manage isolation between projects like chroot and nspawn or Nix’s environments. Then again by using LXD/Incus you get that plus lots of other useful tools baked in.
Regarding not getting an IP address have you checked your base configuration to see if dhcp has been configured for the bridge? If that isn’t the issue then all I can think of is that you somehow deleted the interface and should check the container config.
That said the commands provided above are how I usually access the container command line. For coding I use code-server to put VS Code in a browser. I’m sure there are better options and look forward to the suggestions.
Keep going and learning!
You can run full GUI apps inside LXC containers and have X11 deal with the rest. Guides here and here.
Thanks! I’ve come across many of Simos’ posts while getting up to speed on LXD. I had previously ended up settling on using the forgotten xdmcp to establish and manage the connections. My next go around will probably use a different approach that is more secure.
My use case for code-server is that I can then access the IDE from any computer allowing me greater flexibility of the device that I code on.
