| * Mount proper cgroup for systemd to manage inside of the container.Daniel J Walsh2018-10-15
| | | | | | | | | | | | | | | | | | | | | | | | We are still requiring oci-systemd-hook to be installed in order to run systemd within a container. This patch properly mounts /sys/fs/cgroup/systemd/libpod_parent/libpod-UUID on /sys/fs/cgroup/systemd inside of container. Since we need the UUID of the container, we needed to move Systemd to be a config option of the container. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>

* Drop libnetwork vendor and move the code into pkg/Matthew Heon2018-10-04
| | | | | | | | | | | The vendoring issues with libnetwork were significant (it was dragging in massive amounts of code) and were just not worth spending the time to work through. Highly unlikely we'll ever end up needing to update this code, so move it directly into pkg/ so we don't need to vendor libnetwork.

* | Add support to checkpoint/restore containersAdrian Reber2018-10-03
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | runc uses CRIU to support checkpoint and restore of containers. This brings an initial checkpoint/restore implementation to podman. None of the additional runc flags are yet supported and container migration optimization (pre-copy/post-copy) is also left for the future. The current status is that it is possible to checkpoint and restore a container. I am testing on RHEL-7.x and as the combination of RHEL-7 and CRIU has seccomp troubles I have to create the container without seccomp. With the following steps I am able to checkpoint and restore a container: # podman run --security-opt="seccomp=unconfined" -d registry.fedoraproject.org/f27/httpd # curl -I 10.22.0.78:8080 HTTP/1.1 403 Forbidden # <-- this is actually a good answer # podman container checkpoint <container> # curl -I 10.22.0.78:8080 curl: (7) Failed connect to 10.22.0.78:8080; No route to host # podman container restore <container> # curl -I 10.22.0.78:8080 HTTP/1.1 403 Forbidden I am using CRIU, runc and conmon from git. All required changes for checkpoint/restore support in podman have been merged in the corresponding projects. To have the same IP address in the restored container as before checkpointing, CNI is told which IP address to use. If the saved network configuration cannot be found during restore, the container is restored with a new IP address. For CRIU to restore established TCP connections the IP address of the network namespace used for restore needs to be the same. For TCP connections in the listening state the IP address can change. During restore only one network interface with one IP address is handled correctly. Support to restore containers with more advanced network configuration will be implemented later. v2: * comment typo * print debug messages during cleanup of restore files * use createContainer() instead of createOCIContainer() * introduce helper CheckpointPath() * do not try to restore a container that is paused * use existing helper functions for cleanup * restructure code flow for better readability * do not try to restore if checkpoint/inventory.img is missing * git add checkpoint.go restore.go v3: * move checkpoint/restore under 'podman container' v4: * incorporated changes from latest reviews Signed-off-by: Adrian Reber <areber@redhat.com>

| * Fix cleanupRuntime to only save if container is validMatthew Heon2018-10-02
| | | | | | | | | | | | | | | | | | | | | | We call cleanup() (which calls cleanupRuntime()) as part of removing containers, after the container has already been removed from the database. cleanupRuntime() tries to update and save the state, which obviously fails if the container no longer exists. Make the save() conditional on the container not being in the process of being removed. Signed-off-by: Matthew Heon <matthew.heon@gmail.com>

| * Add ContainerStateExited and OCI delete() in cleanup()Matthew Heon2018-10-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To work better with Kata containers, we need to delete() from the OCI runtime as a part of cleanup, to ensure resources aren't retained longer than they need to be. To enable this, we need to add a new state to containers, ContainerStateExited. Containers transition from ContainerStateStopped to ContainerStateExited via cleanupRuntime which is invoked as part of cleanup(). A container in the Exited state is identical to Stopped, except it has been removed from the OCI runtime and thus will be handled differently when initializing the container.

* Don't output inodes created to run a containerDaniel J Walsh2018-09-21
| | | | | | | | | | | | | | | | | | | | | | | | | | There is a group of inodes that get created when running a container if they do not exist. containerMounts = map[string]bool{ "/dev": true, "/etc/hostname": true, "/etc/hosts": true, "/etc/resolv.conf": true, "/proc": true, "/run": true, "/run/.containerenv": true, "/run/secrets": true, "/sys": true, } If the destination inode does not exist, libpod/runc will create the inode.
