In current CloudStack, the agent-management server communication is weakly secured by one way SSL authentication while encrypted and allows for any client/agent to connect and be served by the management server. There are other services that need TLS/SSL security and upcoming features such as container/application service etc. require certificate management. The common issue is CloudStack has no certificate management to provide security for its internal component especially the agent-mgmt server and mgmt-mgmt server communication. The aim of this feature is to provide pluggable CA (certificate authority) management in CloudStack that can fetch/provision certificates to (new) host(s) and systemvms. As a default CA plugin, a root CA plugin will be implement where CloudStack becomes a self-signed Root Certificate Authority. Developers will have option to implement further integration with their TLS/SSL cert providers such as letsencrypt and other vendors.
