* 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).

* Begin adding support for multiple OCI runtimesMatthew Heon2019-06-19
| | | | | | | | | | | | | Allow Podman containers to request to use a specific OCI runtime if multiple runtimes are configured. This is the first step to properly supporting containers in a multi-runtime environment. The biggest changes are that all OCI runtimes are now initialized when Podman creates its runtime, and containers now use the runtime requested in their configuration (instead of always the default runtime).

* Add support for SCTP port forwardingMatthew Heon2019-03-15
| | | | | | | | | | | | | | | SCTP is already present and enabled in the CNI plugins, so all we need to do to add support is not error on attempting to bind ports to reserve them. I investigated adding this binding for SCTP, but support for SCTP in Go is honestly a mess - there's no widely-supported library for doing it that will do what we need. For now, warn that port reservation for SCTP is not supported and forward the ports. Signed-off-by: Matthew Heon <mheon@redhat.com>

| | | | | | | | | | | | | | | | | | | | To be able to use OCI runtimes which do not implement checkpoint/restore this adds a check to the checkpoint code path and the checkpoint/restore tests to see if it knows about the checkpoint subcommand. If the used OCI runtime does not implement checkpoint/restore the tests are skipped and the actual 'podman container checkpoint' returns an error. Signed-off-by: Adrian Reber <areber@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CRIU can checkpoint and restore processes/containers with established TCP connections if the correct option is specified. To implement checkpoint and restore with support for established TCP connections with Podman this commit adds the necessary options to runc during checkpoint and also tells conmon during restore to use 'runc restore' with '--tcp-established'. For this Podman feature to work a corresponding conmon change is required. Example: $ podman run --tmpfs /tmp --name podman-criu-test -d docker://docker.io/yovfiatbeb/podman-criu-test $ nc `podman inspect -l | jq -r '.[0].NetworkSettings.IPAddress'` 8080 GET /examples/servlets/servlet/HelloWorldExample Connection: keep-alive 1 GET /examples/servlets/servlet/HelloWorldExample Connection: keep-alive 2 $ # Using HTTP keep-alive multiple requests are send to the server in the container $ # Different terminal: $ podman container checkpoint -l criu failed: type NOTIFY errno 0 $ # Looking at the log file would show errors because of established TCP connections $ podman container checkpoint -l --tcp-established $ # This works now and after the restore the same connection as above can be used for requests $ podman container restore -l --tcp-established The restore would fail without '--tcp-established' as the checkpoint image contains established TCP connections.

| * 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>

* | Added option to keep containers running after checkpointingAdrian Reber2018-11-20
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CRIU supports to leave processes running after checkpointing: -R|--leave-running leave tasks in running state after checkpoint runc also support to leave containers running after checkpointing: --leave-running leave the process running after checkpointing With this commit the support to leave a container running after checkpointing is brought to Podman: --leave-running, -R leave the container running after writing checkpoint to disk Now it is possible to checkpoint a container at some point in time without stopping the container. This can be used to rollback the container to an early state: $ podman run --tmpfs /tmp --name podman-criu-test -d docker://docker.io/yovfiatbeb/podman-criu-test $ curl 10.88.64.253:8080/examples/servlets/servlet/HelloWorldExample 3 $ podman container checkpoint -R -l $ curl 10.88.64.253:8080/examples/servlets/servlet/HelloWorldExample 4 $ curl 10.88.64.253:8080/examples/servlets/servlet/HelloWorldExample 5 $ podman stop -l $ podman container restore -l $ curl 10.88.64.253:8080/examples/servlets/servlet/HelloWorldExample 4 So after checkpointing the container kept running and was stopped after some time. Restoring this container will restore the state right at the checkpoint. Signed-off-by: Adrian Reber <areber@redhat.com>
