hydra-cli

hydra-cli lets you talk to the JSON API of hydra on the command line. It includes commands for querying and creating projects and jobsets.

Installation

Use nix-env to install:

nix-env -f https://github.com/nlewo/hydra-cli/archive/master.tar.gz -iA hydra-cli

Build

Inside the provided nix shell:

$ cargo build

Usage

hydra-cli talks to the JSON API of hydra and allows you to query, create and wait for projects and jobsets:

project-create Creates a project.
project-list Lists existing projects.
project-show Shows the projects' information.
jobset-create Creates a jobset in a project.
jobset-wait Waits for a jobset's completion.
reproduce Retrieves information for reproducing an output path.
search Searches for an output path.

By default hydra-cli talks to https://hydra.nixos.org. The default can be overwritten by setting the HYDRA_HOST environment variable or by passing --host <host> on the command line.
