flannel uses an init container to pull CNI from container to the host system in `/etc/cni`. With SELinux, the permission is denied because `/etc/cni` is labelled with `etc_t` so it can't be access by Docker since it expects `svirt_lxc_file_t`. Using `filetrans_pattern` we can define a mechanism to create `/etc/cni` with the correct labels even if it's not yet created - which avoid to run `restorecon` on `/etc/cni`.

flannel will write into /run/flannel/... so we need to provide correct labelling for dir created by docker daemon Signed-off-by: Mathieu Tortuyaux <mathieu@kinvolk.io>

@jepio I thought the same - but when we will upgrade in a couple of months SELinux we will need to chase the "flatcar changes commit" for this package. 🤔 Otherwise I can squash all into one commit |
