1. Objectives

The SSL termination (SSL offloading) feature was introduced in Apache CloudStack 4.13.

    Bug: https://issues.apache.org/jira/browse/CLOUDSTACK-4821
    FS: https://cwiki.apache.org/confluence/display/CLOUDSTACK/SSL+Termination+Support

However, this feature is only implemented for Citrix Netscaler by commit https://github.com/apache/cloudstack/commit/0076307

This improvement derives from a feature design in Apache CloudStack 4.15:  VR haproxy customization in CloudStack (which is not merged)

2. High Level Design

This improves SSL offloading feature which includes

• Manage SSL certificate for accounts on GUI
• Support LB protocol "SSL" when VR is used as LB provider in the network
• Reconfigure HAproxy with sslcerts in VRs when ssl certs is assigned to a LB

3. Implementation

This described some details of the implementation

3.1 database change

None.

3.2 UI changes

3.3 Haproxy configuration for SSL certificate in Virtual Router

example of haproxy.cfg

4. Test plan

- (Optional) Generate self-signed certificate
