In order to install NixOS behind corporate proxy do the usual stuff but before running nixos-install set this environment variable:
export CURL_NIX_FLAGS="-x http://user:password@proxy:port/"
In addition in case you have ties to cloning from GitHub (like vim plugins), you should export proxy related variables:
export HTTP_PROXY=http://user:password@proxy:port/
export HTTPS_PROXY=http://user:password@proxy:port/
export http_proxy=http://user:password@proxy:port/
export https_proxy=http://user:password@proxy:port/
After having stack setup --nix run, consider adding following into your ~/.stack/config.yaml file:
nix:
# false by default. Must be present and set to `true` to enable Nix.
# You can set set it in your `$HOME/.stack/config.yaml` to enable
# Nix for all your projects without having to repeat it
enable: true
# true by default. Tells Nix whether to run in a pure shell or not.
#pure: true
# Empty by default. The list of packages you want to be
# available in the nix-shell at build time (with `stack
# build`) and run time (with `stack exec`).
packages: [zlib]
# Unset by default. You cannot set this option if `packages:`
# is already present and not empty.
#shell-file: shell.nix
# A list of strings, empty by default. Additional options that
# will be passed verbatim to the `nix-shell` command.
#nix-shell-options: []
# A list of strings, empty by default, such as
# `[nixpkgs=/my/local/nixpkgs/clone]` that will be used to override
# NIX_PATH.
#path: []
# false by default. Whether to add your nix dependencies as nix garbage
# collection roots. This way, calling nix-collect-garbage will not remove
# those packages from the nix store, saving you some time when running
# stack build again with nix support activated.
# This creates a `nix-gc-symlinks` directory in the project `.stack-work`.
# To revert that, just delete this `nix-gc-symlinks` directory.
#add-gc-roots: false
