- this needs an init as it does not respond to stop signals, so include tini - needs CAP_SYS_ADMIN to write to kernel entropy estimate - set kernel.random.write_wakeup_threshold so that rngd does not need sysctl write access - build patches from Alpine, but statically linked - remove rngd from base image, means we no longer need community repository Signed-off-by: Justin Cormack <justin.cormack@docker.com>
