Sagitta – SDC Manager GEri is an application to install products available in a catalogue on virtual machines.
Sagitta (the Software Deployment and Configuration -SDC- GE), which is the key enabler used to support automated deployment (installation and configuration) of software on running virtual machines. As part of the complete process of deployment of applications, the aim of Sagitta is to deploy software product instances upon request of the user using the API or through the Cloud Portal.
The steps to install a product are described in form of recipes that indicates how the software (such as Apache Tomcat, MySQL, or HAProxy) has to be deployed. The recipes describe a series of resources that should be configured to start running in a particular state: packages that should be installed, services that should be running, or files that should be copied. Sagitta makes sure each resource is properly configured, and provides a safe, flexible, easily-repeatable mechanism that ensures all the nodes are always running exactly the way they were expected. Recipes belonging to a single product are aggregated in a cookbook for that product, which is stored and managed by Sagitta framework.
All the available recipes needed for the management of a given product are aggregated in a cookbook following a naming convention. Every product supported by Sagitta must have a cookbook with all the required recipes. Some instructions about how to build cookbooks and recipes can be found in "Recipes for GEs".
