========== nix-rehash
Nix development utils that will blow up your mind
reService - fullstack@dev
reService takes your nixos config of services and creates user-enabled supervisord config that you can use for development or deployment on non nixos systems. Having deterministic fullstack in development has never been more awesome.
-
Create
default.nix
{ pkgs ? import <nixpkgs> {} , projectName ? "myProject" , nix-rehash ? import <nix-rehash> }: with pkgs.lib; with pkgs; let services = nix-rehash.reService { name = "${projectName}"; configuration = let servicePrefix = "/tmp/${projectName}/services"; in [ ({ config, pkgs, ...}: { services.postgresql.enable = true; services.postgresql.package = pkgs.postgresql92; services.postgresql.dataDir = "${servicePrefix}/postgresql"; }) ]; }; in myEnvFun { name = projectName; buildInputs = [ services ]; }
-
install
nix-env -f default.nix -i
-
load environemnt
load-env-myProject
-
start services
myProject-start-services
, control servicesmyProject-control-services
, stop servicesmyProject-stop-services
Now build this with hydra and pass the environment around :)
Alternative using nix-shell:
- set
buildInputs = [ services.config.supervisord.bin ];
- run
nix-shell
- use
supervisord
andsupervisorctl
as you wish
reContain - heroku@home
reContain makes nixos enabled installable container that can auto-update itself. Now you can build container on hydra and auto update it on host machine. Staging or deployments have never been easier :)
-
Create
default.nix
{ pkgs ? import <nixpkgs> , name ? "myProject" , nix-rehash ? import <nix-rehash> }: with pkgs.lib; with pkgs; { container = nix-rehash.reContain { inherit name; configuration = [{ services.openssh.enable = true; services.openssh.ports = [ 25 ]; users.extraUsers.root.openssh.authorizedKeys.keys = [ (builtins.readFile ./id_rsa.pub) ]; }]; }; }
-
do
nix-env [-f default.nix] -i myProject-container
or build with hydra and add a channel -
start container:
sudo myProject-start-container
-
ssh to container:
ssh localhost -p 25
-
enable auto updates with cron:
* * * * * nix-env -i myProject-container && sudo $HOME/.nix-profile/bin/myProject-update-container
-
stop container:
sudo myProject-stop-container
