FAQ¶
1. What version of the self-hosted controller am I running?¶
To check the version of the self-hosted controller you are currently running, follow these steps:
- Log into the Console
- On the right-hand side at the bottom, you will see the controller version displayed
- For example:
Controller Version: 3.1-v3-13
(as shown in the screenshot below)
2. How are security patches and CVE updates delivered to the Rafay Controller in an air-gapped environment?¶
Rafay performs comprehensive CVE scans for every controller release and includes the latest security patches. For air-gapped environments, updated controller packages or components are provided as needed. CVE response is prioritized, and vulnerability management is part of our continuous release process.
If you identify any security issues using your own scanning tools, please reach out to Rafay Support. We will take immediate action and provide a fix, if applicable.
3. In an air-gapped setup with 3-node HA, how are roles and DNS records handled?¶
- Node Roles: In a 3-node HA configuration, all three nodes act as masters. A worker node can also be added if required
- DNS Records: A single DNS record can point to multiple IPs (all three master nodes) using A records
- Best Practice: While it is technically possible to configure DNS for just one node, this is not recommended. Using all three master IPs ensures high availability and failover
