|\ | | | | Add tcp-established to checkpoint/restore
| * Fix podman container restore -aAdrian Reber2018-11-28
| | | | | | | | | | | | | | | | | | | | | | | | | | podman container restore -a was using the wrong filter to restore checkpointed containers. This switches from 'running' containers to 'exited' containers. Restoring with -a only works if all exited containers have been checkpointed. Maybe it would make sense to track which containers have been really checkpointed. This is just to fix '-a' to work at least if all exited containers have been checkpointed.

| * Added tcp-established to checkpoint/restoreAdrian Reber2018-11-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | /etc/resolv.conf and /etc/hosts should not be created and mounted when the network is disabled. We should not be calling the network setup and cleanup functions when it is disabled either. In doing this patch, I found that all of the bind mounts were particular to Linux along with the generate functions, so I moved them to container_internal_linux.go Since we are checking if we are using a network namespace, we need to check after the network namespaces has been created in the spec.

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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As discussed [1], the runlabel command should execute any command specified in a label. The reasoning behind is that we cannot restrict which options are passed to Podman which thereby has full access to the host (runlabels must be used with care). With the updated semantics, runlabel will substitute the commands with a basepath equal to "docker" or "podman" with "/proc/self/exe", and otherwise leave the command unchanged to execute any other command on the host.
