From f3f4c54f2abc341cee1e7b83e9538d91a3c627e3 Mon Sep 17 00:00:00 2001 From: Valentin Rothberg Date: Tue, 7 Jan 2020 16:48:07 +0100 Subject: policy for seccomp-profile selection Implement a policy for selecting a seccomp profile. In addition to the default behaviour (default profile unless --security-opt seccomp is set) add a second policy doing a lookup in the image annotation. If the image has the "io.containers.seccomp.profile" set its value will be interpreted as a seccomp profile. The policy can be selected via the new --seccomp-policy CLI flag. Once the containers.conf support is merged into libpod, we can add an option there as well. Note that this feature is marked as experimental and may change in the future.
