 - Windows-based container images aren't supported.
 - Only "OS-level" vulnerabilities that originate from system packages will be patched. This includes system packages in the container image managed by an OS package manager such as "apt” and "yum”. Vulnerabilities that originate from application packages, such as packages used by programming languages like Go, Python, and NodeJS are unable to be patched.  
 - End of Service Life (EOSL) images are not supported by Continuous Patching. EOSL images refer to images where the underlying operating system is no longer offering updates, security patches, and technical support. Examples include images based on older operating system versions such as Debian 8 and Fedora 28. EOSL images will be skipped from the patch despite having vulnerabilities - the recommended approach is to upgrade your the underlying operating system of your image to a supported version.
