* gnu/build/linux-container.scm (call-with-container): Add #:process-spawned-hook and honor it. * gnu/system/linux-container.scm (container-script)[script]: Define 'explain' and pass it as #:process-spawned-hook'.
2019-09-12linux-container: Exclude more services when sharing networking with the host.Ludovic Courtès
* gnu/system/linux-container.scm (containerized-operating-system)[useless-services]: Add more services to the list when SHARED-NETWORK? is true.
2019-09-12file-systems: Add /var/run/nscd to '%network-file-mappings'.Ludovic Courtès
This allows containers created by "guix environment -CN" or by "guix system container -N" to talk to the host nscd. * gnu/system/file-systems.scm (%network-file-mappings): Add "/var/run/nscd". * gnu/build/shepherd.scm (default-mounts)[nscd-socket]: Remove. * gnu/system/linux-container.scm (container-script)[nscd-run-directory] [nscd-mapping, nscd-os, nscd-specs]: Remove.

* gnu/system/linux-container.scm (containerized-operating-system): (container-script): Check for existence of the host nscd run directory in the container script.

2019-05-15linux-container: Compute essential services for THIS-OPERATING-SYSTEM.Ludovic Courtès
Previously, the 'essential-services' would correspond to the initial, non-containerized OS. Thus, all the file systems removed in 'container-essential-services' would actually still be there because the essential services would be computed on the non-containerized OS. This is a followup to 69cae3d3356a69b7fe69481338f760545995485e. * gnu/system/linux-container.scm (container-essential-services): Call 'operating-system-default-essential-services' to get the baseline services. (containerized-operating-system): Pass THIS-OPERATING-SYSTEM, not OS, to 'container-essential-services'. Add a dummy root file system to 'file-systems'. (container-script)[mountable-file-system?]: New procedure. Use it.
2019-05-15linux-container: Do not add %CONTAINER-FILE-SYSTEMS to Docker image OSes.Ludovic Courtès
Previously, 'guix system docker-image' would end up providing an OS that would try to mount all of %CONTAINER-FILE-SYSTEMS as well as /gnu/store, which is bound to fail in unprivileged Docker. This patch makes it so that 'guix system container' still gets those file systems, but 'guix system docker-image' doesn't. * gnu/system/linux-container.scm (containerized-operating-system): Add #:extra-file-systems parameter and honor it. Do not include %STORE-MAPPING and SHARED-NETWORK-FILE-MAPPINGS. (container-script): Add %STORE-MAPPING and optionally NETWORK-MAPPINGS to MAPPINGS and pass #:extra-file-systems.
2019-05-14linux-container: Support container network sharing.Arun Isaac
* gnu/system/linux-container.scm (container-essential-services): If network is to be shared with the host, remove network configuration files from etc service. (containerized-operating-system): If network is to be shared with the host, remove nscd service and map host's /var/run/nscd if it exists. (container-script): If network is to be shared with the host, do not create network namespace. * 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? argument. * doc/guix.texi (Invoking guix system): Document the "-N, --network" option.
