From 36a4dc7a6f32cccf1d9e4cdccb46b5cb18de2210 Mon Sep 17 00:00:00 2001 From: Christopher Baines Date: Fri, 27 Jan 2017 06:15:09 +0000 Subject: scripts: system: Add support for container network sharing. This is a port of the functionality in the Guix environment command to the guix system container command. This requires additional changes to the operating-system definitions used, in particular, networking related services may need removing if the host network is shared. * guix/scripts/system.scm (system-derivation-for-action): Add #:container-shared-network? argument. (perform-action): Add #:container-shared-network? argument. (show-help): Add "-N, --network" help information. (%options): Add network option. (process-action): Call perform-action with #:container-shared-network?. * gnu/system/linux-container.scm (%network-configuration-files): New variable. (container-script): Add support for returning a container script that shares the host network. * gnu/system.scm (essential-services): Add #:container-shared-network? argument. (operating-system-services): Add #:container-shared-network? argument. (operating-system-etc-service): Add #:container-shared-network? argument, and support for ommiting some configuration if the network is shared. (operating-system-activation-script): Add #:container-shared-network? argument, and pass this through to the operating-system-services procedure. (operating-system-boot-script): Add #:container-shared-network? argument, and pass this through to the operating-system-services procedure. (operating-system-derivation): Add the #:container-shared-network? argument, and pass this through to the operating-system-services procedure. (operating-system-profile): Add the #:container-shared-network? argument, and pass this through to the operating-system-services procedure. --- guix/scripts/system.scm | 18 ++++++++++++++++-- 1 file changed, 16 insertions(+), 2 deletions(-) (limited to 'guix/scripts/system.scm') diff --git a/guix/scripts/system.scm b/guix/scripts/system.scm index acfccce96d..160324ce89 100644 --- a/guix/scripts/system.scm +++ b/guix/scripts/system.scm @@ -678,13 +678,15 @@ checking this by themselves in their 'check' procedure."
