saltstack-vulcan

Vulcan is a formula build tool for SaltStack. The idea is to assemble formulas from remote Git repositories to create an atomic 'build' for deployment.

SaltStack has a native package manager which is a system package manager (SPM). It assembles formulas from remote locations but is geared towards assembling on the Salt master itself and requires extra metadata.

Salt is also capable of loading formulas from Git using a fileserver_backend however this too is geared towards assembly on the host itself.

The goal of this project is to make it easy to assemble formulas from Git repositories during a build stage running on something like Jenkins. After assembly, all files can be delivered to Salt master(s) in an atomic way. This makes it easier to keep multiple masters sync'd and Docker based Salt master deployments easier.

Installation

sudo pip install saltstack-vulcan -U

Configuration

Configuration is handled by a local YAML file. By default, $PWD/vulcan.yaml is used. An alternative path can be set with the --config flag.

Formula configuration is stored as a list of dictionaries. Each formula has the following attributes. Only 'name' and 'url' are required however it is best practice to set the branch and revision as well.

• name: A name for the formula for example 'apache' or 'mysql'. This is required.
• url: Git URL for the project. This is required.
• branch: Name of branch for checkout. Defaults to 'master'.
• revision: Git revision to use. If this does not exists, an exception will be thrown. Defaults to 'HEAD'.
• origin_name**: If renaming a formula, the origin_name of the formula must be used to determine the change. Defaults to value of 'name' if not set.
• install_directory: Directory to install formula into. Defaults to ./formulas.
