How does nix shell work?
The command nix-shell will build the dependencies of the specified derivation, but not the derivation itself. It will then start an interactive shell in which all environment variables defined by the derivation path have been set to their corresponding values, and the script $stdenv/setup has been sourced.
Can I use ENV variable in Dockerfile?
Environment variables can be defined in the Dockerfile. This can simply be done through the use of the ENV instruction. The environment variables defined by the ENV instruction in the Dockerfile can be used in the resulting image and container. This can be done through the use of the docker-compose run command.
What happens if I change the stateversion of NixOS?
The effect is that NixOS will option defaults corresponding to the specified release (such as using an older version of PostgreSQL). Do NOT change the stateVersion in the configuration; [it] tells nixos what version your state is; changing it will break the things [it is] meant to fix. When can I update stateVersion?
What do you need to know about NixOS?
This manual describes how to install, use and extend NixOS, a Linux distribution based on the purely functional package management system Nix, that is composed using modules and packages defined in the Nixpkgs project.
Where are nixpkgs configuration files stored in NixOS?
{ nixpkgs.config = { allowUnfree = true; }; } However, this does not allow unfree software for individual users. Their configurations are managed separately. A user’s nixpkgs configuration is stored in a user-specific configuration file located at ~/.config/nixpkgs/config.nix.
How to install a library in Nix shell?
With nix, only applications should be installed into profiles. Libraries are used using nix-shell. If you want to compile a piece of software that requires zlib and uses pkg-config to discover it, run nix-shell -p gcc pkg-config zlib to get into a shell with the appropriate environment variables set.
