* Functionality changes to the following flagsumohnani82018-04-06
| | | | | | | | | | | | | | | | | | | --group-add --blkio-weight-device --device-read-bps --device-write-bps --device-read-iops --device-write-iops --group-add now supports group names as well as the gid associated with them. All the --device flags work now with moderate changes to the code to support both bps and iops. Added tests for all the flags.

* Refactor dependency checks from init() into public APIMatthew Heon2018-04-03
| | | | | | | | | | | | | Instead of checking during init(), which could result in major locking issues when used with pods, make our dependency checks in the public API instead. This avoids doing them when we start pods (where, because of the dependency graph, we can reasonably say all dependencies are up before we start a container).

* More gracefully handle unexpected storage deletionMatthew Heon2018-04-02
| | | | | | | | | | | | | | | | | | We have other tools using containers/storage. They can delete our containers in c/storage without us knowing. Try and handle this better by warning instead of erroring when delete our storage and it is already gone. This does not handle cases where libpod thinks the container is mounted, but it is not. This is harder to check for, because c/storage Mount() and Unmount() take a layer, image, or container and that complicates our "container no longer exists" question. Further work is needed here.

* Add secrets patch to podmanumohnani82018-03-29
| | | | | | | | | | Adds support for mounting secrets especially on RHEL where the container can use the host subsription to run yum Signed-off-by: umohnani8 <umohnani@redhat.com> Closes: #544 Approved by: rhatdan
* Check for duplicate names when generating new container and pod names.Daniel J Walsh2018-03-29
| | | | | | | | | This fixes the situation where we fail to create a container when a name already exists. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com> Closes: #517 Approved by: baude
* Make container env variable conditionalMatthew Heon2018-03-23
| | | | | | | | | | | | Add only when it's not already present. Add a more specific version in podman spec generation so we get 'container=podman' not 'container=libpod' Signed-off-by: Matthew Heon <matthew.heon@gmail.com> Closes: #540 Approved by: baude

* Stage3 Image Librarybaude2018-03-14
| | | | | | | | | | | | | This represents the stage3 implementation for the image library. At this point, we are moving the image-centric functions to pkg/image including migration of args and object-oriented references. This is a not a one-for-one migration of funcs and some funcs will need to continue to reside in runtime_img as they are overly specific to libpod and probably not useful to others.

* Modify pod API to move Init() into Start()Matthew Heon2018-03-13
| | | | | | | | | | | | | Separate Init() and Start() does not make sense on the pod side, where we may have to start containers in order to initialize others due to dependency orders. Also adjusts internal containers API for more code sharing. Signed-off-by: Matthew Heon <matthew.heon@gmail.com> Closes: #478 Approved by: rhatdan
* Convert bind mounts to use DB fieldMatthew Heon2018-03-08
| | | | | | | | | | | | | | | Refactors creation of bind mounts into a separate function that can be called from elsewhere (e.g. pod start or container restart). This function stores the mounts in the DB using the field established last commit. Spec generation now relies upon this field in the DB instead of manually enumerating files to be bind mounted in.

| | | | | | | | | | We don't want this in our public API - better to let us control what gets put in container storage and where. Signed-off-by: Matthew Heon <matthew.heon@gmail.com> Closes: #462 Approved by: baude

| | | | | | | | | | | | | | | | | | Each of these options are destructive in nature, meaning if the user adds one of them, all current ones are removed from the produced resolv.conf. * dns-server allows the user to specify dns servers. * dns-opt allows the user to specify special resolv.conf options * dns-search allows the user to specify search domains The add-host option is not destructive and truly just adds the host to /etc/hosts.

Weighing in at ~1700 lines, container.go is just too big. Split it into three files: core structs and accessors (container.go), public API (container_api.go), and internal functions (container_internal.go). Signed-off-by: Matthew Heon <matthew.heon@gmail.com>
