This project contains the source code for an implementation of using OpenStack as a Web Cloud Provider in VISA.
VISA (Virtual Infrastructure for Scientific Analysis) makes it simple to create compute instances on facility cloud infrastructure to analyse your experimental data using just your web browser.
See the User Manual for deployment instructions and end user documentation.
The VISA Cloud Web Provider OpenStack providers a RESTful web service for interacting with the Openstack API. VISA can be configured to use a web provider that will contact your cloud provider of choice.
This project can be used as a good starting point if you wish to implement your own provider (i.e. proxmox, aws etc.)
This is currently a WIP and is not at a mature enough level to be used in production on the VISA platform
npm install
npm start
The application requires environment variables to be set. These can be in a .env file at the root of the project. Details of the environment variables are given below.
The following environment variables are used to configure VISA Cloud Web Provider for OpenStack and can be placed in a .env file:
| Environment variable | Default value | Usage |
|---|---|---|
| VISA_WEB_PROVIDER_OPENSTACK_SERVER_PORT | 4000 | The port on which to run the server |
| VISA_WEB_PROVIDER_OPENSTACK_SERVER_HOST | localhost | The hostname on which the server is listening on |
| VISA_WEB_PROVIDER_OPENSTACK_SERVER_AUTH_TOKEN | The expected x-auth-token value |
|
| VISA_WEB_PROVIDER_OPENSTACK_LOG_LEVEL | 'info' | Application logging level |
| VISA_WEB_PROVIDER_OPENSTACK_LOG_TIMEZONE | The timezone for the formatting the time in the application log | |
| VISA_WEB_PROVIDER_OPENSTACK_LOG_SYSLOG_HOST | The syslog host (optional) | |
| VISA_WEB_PROVIDER_OPENSTACK_LOG_SYSLOG_PORT | The syslog port (optional) | |
| VISA_WEB_PROVIDER_OPENSTACK_LOG_SYSLOG_APP_NAME | The syslog application name (optional) | |
| VISA_WEB_PROVIDER_OPENSTACK_IDENTITY_ENDPOINT | The API endpoint to the OpenStack Identity API | |
| VISA_WEB_PROVIDER_OPENSTACK_COMPUTE_ENDPOINT | The API endpoint to the OpenStack Compute API | |
| VISA_WEB_PROVIDER_OPENSTACK_IMAGE_ENDPOINT | The API endpoint to the OpenStack Image API | |
| VISA_WEB_PROVIDER_OPENSTACK_NETWORK_ENDPOINT | The API endpoint to the OpenStack Network API | |
| VISA_WEB_PROVIDER_OPENSTACK_APPLICATION_ID | The application id for an OpenStack Application Credential | |
| VISA_WEB_PROVIDER_OPENSTACK_APPLICATION_SECRET | The application secret for an OpenStack Application Credential | |
| VISA_WEB_PROVIDER_OPENSTACK_ADDRESS_PROVIDER | The OpenStack network address provider | |
| VISA_WEB_PROVIDER_OPENSTACK_ADDRESS_PROVIDER_UUID | The OpenStack network UUID | |
| VISA_WEB_PROVIDER_OPENSTACK_HTTP_TIMEOUT | 5000 (5s) | The requests to OpenStack will timeout if the duration (ms) exceeds this value |
