15 A tool for generating SELinux security profiles for containers. The
16 whole concept is based on the "block inheritance" feature inside the
17 CIL intermediate language supported by the SELinux user space. The tool
18 creates a policy which combines rules inherited from specified CIL
19 blocks (templates) and rules discovered by inspection of the container
20 JSON file with mount points and port definitions.

103 Since it is not possible to detect capabilities used by a container in
104 Docker Engine, you have to use '-c' to specify capabilities for docker
105 container manually.
106
107 It is not possible to generate a custom local policy using the
108 "audit2allow -M" command from AVCs where source context was generated
109 by udica. For this purpose please use '--append-rules' option.
110
111 In some situations udica fails to identify which container engine is
112 used, therefore "--container-engine" parameter has to be used to inform
113 udica how JSON inspection file should be parsed.
