Murano API

Glossary

Environment

The environment is a set of applications managed by a single project (tenant). They could be related logically with each other or not. Applications within a single environment may comprise of complex configuration while applications in different environments are always independent from one another. Each environment is associated with a single OpenStack project.

Session

Since murano environments are available for local modification for different users and from different locations, it's needed to store local modifications somewhere. Sessions were created to provide this opportunity. After a user adds an application to the environment - a new session is created. After a user sends an environment to deploy, a session with a set of applications changes status to deploying and all other open sessions for that environment become invalid. One session could be deployed only once.
Object Model

Applications are defined in MuranoPL object model, which is defined as a JSON object. The murano API doesn't know anything about it.
Package

A .zip archive, containing instructions for an application deployment.
Environment-Template

The environment template is the specification of a set of applications managed by a single project, which are related to each other. The environment template is stored in an environment template catalog, and it can be managed by the user (creation, deletion, updating). Finally, it can be deployed on OpenStack by translating into an environment.

Application management API

All applications should be created within an environment and all environment modifications are held within the session. Local changes apply only after successful deployment of an environment session.

Get application details

Using GET requests to applications endpoint user works with list containing all applications for specified environment. A user can request a whole list, specific application, or specific attribute of a specific application using tree traversing. To request a specific application, the user should add to endpoint part an application id, e.g.: /environments/<env_id>/services/<application_id>. For selection of specific attribute on application, simply appending part with attribute name will work. For example to request application name, user should use next endpoint: /environments/<env_id>/services/<application_id>/name
