[Question] When using flakes, can I remove all channels?
You don't need channels to use nix-shell or nix-env. You can generate the Nix path and registry from your flake inputs. flake-utils-plus makes this easy with nix.generateRegistryFromInputs and nix.generateNixPathFromInputs.
-
How do I deploy a configuration to a machine with an existing hardware-configuration.nix?
Use flake-utils-plus to easily define multiple systems in flake.nix.and then use the --target-host flag of nixos-rebuild to deploy it remotely.
-
Have a shell command in configuration.nix that runs on nixos-rebuild
If you're trying to handle multiple systems with one config a flake is a significantly better option. I would personally recommend looking at flake-utils-plus and specifically this example config.

Best way to manage multiple home manager configs for both NixOS and non-NixOS systems using flakes?
I looked at some past threads / examples and saw people recommend flake-utils-plus, but after reading the examples I don't understand how I would get home-manager on Darwin or Ubuntu.

Nix: Taming Unix with Functional Programming
Depending on your specific needs, the channelsConfig (modify arguments passed to Nixpkgs) and overlay tooling in flake-utils-plus may be adequate: https://github.com/gytis-ivaskevicius/flake-utils-plus/tree/...

What to do...
For flakes you don't have to set up everything manually there are helper libraries, I use flake-utils-plus.
-
How shall I install a package not found at https://search.nixos.org/packages?
Converting to flakes is not that hard if you use a good library. The documentation is other people's configs, really.
-
I made a thing you can load in Nix repl to get variables from your NixOS configuration
Neat! I've been using flake-utils-plus's implementation until now. https://github.com/gytis-ivaskevicius/flake-utils-plus/blob/master/lib/repl.nix
-
How to use a patched nixpkgs locally?
I use flake-utils-plus based configuration to apply patches on top of nixpkgs where overlays don't suffice.

Throwing some Nix in the Mix
Luckily, I did not have to start from scratch as Nix serves their own docker image. I mounted one of my directories and was able to drop into a Nix shell with my configuration file.
-
NixOS 21.05 Released
There is one: https://github.com/NixOS/docker
But it's more of a Nix docker image than a NixOS one, because half of the things that NixOS gives you don't really make much sense in a docker image (systemd in a container?).

Self hosted IRL achievements list?
I only know of the nix package manager. https://hub.docker.com/r/nixos/nix

What tools do people use for DevOps pipelines / continuous delivery?
Ability to run buildkite agents inside a kubernetes cluster on preemble instances without need to modify agent’s Dockerfile every time new dependency comes up - was one of major reasons to learn Nix. I’m just using nixos/docker image as a base, install buildkite-agent and some base stuff like bash via nix-env inside Dickerfile, everything else lays in flake.nix of every project my dockerized nixified buildkite agent run.
