Some Usage Examples

Build a Docker image for the contrail-api-server

% nix-build -A dockerImages.contrailApi
% docker load -i result

To run the contrail test

% nix-build -A contrail32Cw.test.allInOne
% firefox result/log.html

To interactively run a contrail all-in-one VM

% nix-build -A contrail32Cw.test.allInOne.driver
% QEMU_NET_OPTS="hostfwd=tcp::2222-:22" ./result/bin/nixos-run-vms
% ssh -p 2222 root@localhost

To test Hydra jobs

Jobs are classic Nix expressions, so to test them, you just have to build them:

% nix-build jobset.nix -A dockerImages.contrailApi --arg cloudwatt $PWD

Note pushImages expressions uses environment variables to provide registry credentials.

To publish a Docker image, see this doc.

How external repositories are managed

Expressions from the nixpkgs and nixpkgs-contrail repositories are required to build expressions. The file nixpkgs-fetch.nix specifies the commit id that we use by default. For instance, nix-build -A contrail.contrailApi builds the contrail-api-server by using commit id specified in nixpkgs-fetch.nix.

You can easily override them: % nix-build -A contrail32Cw --arg contrail /path/to/nixpgs-contrail.git --arg nixpkgs /path/to/nixpkgs.git

Build a CI

See CI doc.

List attributes examples

Root attribute are contrail, ci, images. For instance, to list all images

% nix-env -f default.nix -qaP -A dockerImages
images.contrailApi        docker-image-contrail-api.tar.gz
images.contrailDiscovery  docker-image-contrail-discovery.tar.gz
