* remove libpod from mainbaude2019-06-25
| | | | | | | | | | | | | the compilation demands of having libpod in main is a burden for the remote client compilations. to combat this, we should move the use of libpod structs, vars, constants, and functions into the adapter code where it will only be compiled by the local client. this should result in cleaner code organization and smaller binaries. it should also help if we ever need to compile the remote client on non-Linux operating systems natively (not cross-compiled).

* enable podman-remote on windowsbaude2019-04-30
| | | | | | | build a podman-remote binary for windows that allows users to use the remote client on windows and interact with podman on linux system. Signed-off-by: baude <bbaude@redhat.com>
* Use also a struct to pass options to Restore()Adrian Reber2018-11-28
| | | | | | | | | | | | | This is basically the same change as ff47a4c2d5485fc49f937f3ce0c4e2fd6bdb1956 (Use a struct to pass options to Checkpoint()) just for the Restore() function. It is used to pass multiple restore options to the API and down to conmon which is used to restore containers. This is for the upcoming changes to support checkpointing and restoring containers with '--tcp-established'. Signed-off-by: Adrian Reber <areber@redhat.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>
* Have info print conmon/oci runtime informationDaniel J Walsh2018-08-07

* more changes to compile darwinbaude2018-07-05
| | | | | | | | | | | | | | | | this should represent the last major changes to get darwin to **compile**. again, the purpose here is to get darwin to compile so that we can eventually implement a ci task that would protect against regressions for darwin compilation. i have left the manual darwin compilation largely static still and in fact now only interject (manually) two build tags to assist with the build. trevor king has great ideas on how to make this better and i will defer final implementation of those to him.
