NAME

7       udica - a tool for generating SELinux security profiles for containers.

SYNOPSIS

11       udica [options] container_name
12
13

DESCRIPTION

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.

SUPPORTED CONTAINER ENGINES

48              use for Docker Engine, see the BUGS section)
49
50
51       -a, --append-rules FILE
52              Append  more  SELinux allow rules generated from SELinux denials

58
59
60       -e, --container-engine ENGINE
61              Specify which container engine is used for  the  inspected  con‐
62              tainer (supports: CRI-O, docker, podman)
63
64
65       --full-network-access

67
68
69       --tty-access
70              Allow a container to read and write the controlling terminal
71
72
73       --X-access
74              Allow a container to communicate with the X server

EXIT STATUS

82       0      no errors encountered.
83
84       1      other errors.
85
86       2      error while parsing options.
87
88       3      error while getting container info.
89
90       4      error while creating an SELinux policy.

EXAMPLES

94       # cat my_con.json | udica --x-access --full-network-access my_container
95       Creates a new SELinux policy with name my_container based on inspecting container and adding access to the X server and full network access.

BUGS

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.
