* 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. Make a few small changes to remove the need for the remainder of libnetwork. Signed-off-by: Matthew Heon <matthew.heon@gmail.com>

* | 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>

| | | | | | | | | | | | | | | | | | | | | | 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.

| * 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.

But collecting them and including them in the error message will make it easier for callers who don't have debugging enabled to figure out what's going wrong.

With this commit and a config like: $ cat /etc/containers/registries.conf [registries.search] registries = ['registry.access.redhat.com', 'quay.io', 'docker.io'] pulling an unqualified missing image looks like: $ podman pull does-not/exist Trying to pull registry.access.redhat.com/does-not/exist:latest...Failed Trying to pull quay.io/does-not/exist:latest...Failed Trying to pull docker.io/does-not/exist:latest...Failed error pulling image "does-not/exist": unable to pull does-not/exist: 3 errors occurred: * Error determining manifest MIME type for docker://registry.access.redhat.com/does-not/exist:latest: Error reading manifest latest in registry.access.redhat.com/does-not/exist: unknown: Not Found * Error determining manifest MIME type for docker://quay.io/does-not/exist:latest: Error reading manifest latest in quay.io/does-not/exist: unauthorized: access to the requested resource is not authorized * Error determining manifest MIME type for docker://does-not/exist:latest: Error reading manifest latest in docker.io/does-not/exist: errors: denied: requested access to the resource is denied unauthorized: authentication required A qualified image looks like: $ podman pull quay.io/does-not/exist Trying to pull quay.io/does-not/exist...Failed error pulling image "quay.io/does-not/exist": unable to pull quay.io/does-not/exist: unable to pull image: Error determining manifest MIME type for docker://quay.io/does-not/exist:latest: Error reading manifest latest in quay.io/does-not/exist: unauthorized: access to the requested resource is not authorized If one of the searched repositories was offline, you'd get a more useful routing error for that specific registry.
