containers[] .securityContext .privileged == true

Privileged containers can allow almost completely unrestricted host access

Privileged containers share namespaces with the host system, eschew cgroup restrictions, and do not offer any security. They should be used exclusively as a bundling and distribution mechanism for the code in the container, and not for isolation.


  • Processes within the container get almost the same privileges that are available to processes outside a container
  • Privileged containers have significantly fewer kernel isolation features
  • root inside a privileged container is close to root on the host as User Namespaces are not enforced
  • Privileged containers shared /dev with the host, which allows mounting of the host’s filesystem
  • They can also interact with the kernel to load kernel and alter settings (including the hostname), interfere with the network stack, and many other subtle permissions
