• Easy configuration management.
• Detect relevant packages, files, and source installs.
• Generate reusable server configs.
• Convert blueprints to Puppet or Chef.
• No DSLs, no extra servers, no workflow changes.

Blueprint looks inside popular package managers, finds changes you made to configuration files, and archives software you built from source. It runs on Debian- and RPM-based Linux distros with Python >= 2.6 and Git >= 1.7. Comprehensive documentation and examples in the Blueprint book.

• Centralized configuration management.
• Export and backup server configurations.
• Push and pull blueprints anywhere.
• Bootstrap servers painlessly.

Blueprint I/O pushes and pulls blueprints to and from a Blueprint I/O Server, making it easy to use blueprints anywhere. DevStructure provides a free Blueprint I/O Server at https://devstructure.com, which stores blueprints in Amazon S3. Alternatively, you can build your own backend server implementing the Blueprint I/O API.

blueprint create my-first-blueprint

Blueprint inspects your server and stores the results in its local repository. blueprint list shows all the blueprints you've created on this server.

blueprint apply my-first-blueprint

Blueprint generates shell code from my-first-blueprint and executes it on the server.

blueprint show -S my-first-blueprint

my-first-blueprint.sh is written to your working directory. Try out -P or -C to generate a Puppet module or a Chef cookbook.

blueprint diff foo bar baz

Blueprint subtracts bar from foo. Files, packages and source that appears in foo but not bar will be carried over to baz and everything else will be dropped.

blueprint push my-first-blueprint

The blueprint and its files are stored remotely. You get a secret URL for accessing it.

blueprint pull https://devstructure.com/MY-SECRET-KEY/my-first-blueprint

The blueprint is stored locally and ready for use.

Prerequisites:

• A Debian- or RPM-based Linux distribution
• Python >= 2.6
• Git >= 1.7

git clone git://github.com/devstructure/blueprint.git
cd blueprint
git submodule update --init
make && sudo make install

rpm -Uvh http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-4.noarch.rpm
yum install python26
git clone git://github.com/devstructure/blueprint.git
cd blueprint && make && sudo make install PYTHON=/usr/bin/python26

This installs Python 2.6 from EPEL side-by-side with Python 2.4 and so won't break yum.

DevStructure maintains Debian packages and Python eggs for Blueprint. See Installing with a package manager on the wiki.

The Blueprint book is a comprehensive overview of the tool including philosophy, installation and detailed examples.

The Blueprint tutorial works through creating and deploying a simple web application via Blueprint.

The HTTP endpoints and protocols used by blueprint-push(1) and blueprint-pull(1) are documented so that others may run compatible servers.

• blueprint-list(1): list all blueprints.
• blueprint-create(1): create a blueprint.
• blueprint-rules(1): create a blueprint from a blueprint-rules file.
• blueprint-show(1): generate code from a blueprint.
• blueprint-diff(1): save the difference between two blueprints.
• blueprint-split(1): split one blueprint into two others interactively.
• blueprint-prune(1): select a subset of resources interactively.
• blueprint-template(1): render mustache.sh templates locally.
• blueprint-apply(1): run a blueprint's generated shell code.
• blueprint-push(1): push a blueprint to the Internet.
• blueprint-pull(1): pull a blueprint from the Internet.
• blueprint-destroy(1): destroy a blueprint.
• blueprint(5): Blueprint JSON format.
• blueprintignore(5): ignore specific files when creating blueprints.
• blueprint-rules(5): enumerate resources in blueprints.
• blueprint.cfg(5): centralized blueprint service configuration.
• blueprint-template(5): mustache.sh template language syntax.
• blueprint-template(7): built-in template data.
• blueprint(7): Blueprint Python library.

• blueprint-git(1)
• blueprint-show-files(1)
• blueprint-show-ignore(1)
• blueprint-show-packages(1)
• blueprint-show-services(1)
• blueprint-show-sources(1)
