* | Remove --sync flag from `podman rm`Matthew Heon2018-12-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Per discussion with Dan, it would be better to automatically handle potential runtime errors by automatically syncing if they occur. Retaining the flag for `ps` makes sense, as we won't even be calling the OCI runtime and as such won't see errors if the state desyncs, but rm can be handled automatically. The automatic desync handling code will take some additional work so we'll land this as-is (sync on ps is enough to solve most desync issues). Signed-off-by: Matthew Heon <mheon@redhat.com>
* | Add --sync flag to podman psMatthew Heon2018-12-06
| | | | | | | | | | | | | | | | | | | | | | The previous commit added support for --sync to podman rm to ensure state inconsistencies would not prevent containers from being removed. Add the flag to podman ps as well, so that all containers can be forcibly synced and all state inconsistencies resolved. Signed-off-by: Matthew Heon <mheon@redhat.com>
* | Add --sync option to podman rmMatthew Heon2018-12-06
|/ | | | | | | | | | | With the changes made recently to ensure Podman does not hit the OCI runtime as often to sync state, we can find ourselves in a situation where the runtime's state does not match ours. Add a --sync flag to podman rm to ensure we can still remove containers when this happens. Signed-off-by: Matthew Heon <mheon@redhat.com>

| * | Move rootless storage config into libpodMatthew Heon2018-12-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previous commits ensured that we would use database-configured paths if not explicitly overridden. However, our runtime generation did unconditionally override storage config, which made this useless. Move rootless storage configuration setup to libpod, and change storage setup so we only override if a setting is explicitly set, so we can still override what we want.

The reason this was caught is people > are trying to get hooks to work with CoreOS. You are not allowed to > write to /usr/share... on CoreOS, so they wanted podman to also look > at /etc, where users and third parties can write. But we'd also been disabling hooks completely for rootless users. And even for root users, the override logic was tricky when folks actually had content in both directories. For example, if you wanted to disable a hook from the default directory, you'd have to add a no-op hook to the override directory. Also, the previous implementation failed to handle the case where there hooks defined in the override directory but the default directory did not exist: $ podman version Version: 0.11.2-dev Go Version: go1.10.3 Git Commit: "6df7409cb5a41c710164c42ed35e33b28f3f7214" Built: Sun Dec 2 21:30:06 2018 OS/Arch: linux/amd64 $ ls -l /etc/containers/oci/hooks.d/test.json -rw-r--r--. 1 root root 184 Dec 2 16:27 /etc/containers/oci/hooks.d/test.json $ podman --log-level=debug run --rm docker.io/library/alpine echo 'successful container' 2>&1 | grep -i hook time="2018-12-02T21:31:19-08:00" level=debug msg="reading hooks from /usr/share/containers/oci/hooks.d" time="2018-12-02T21:31:19-08:00" level=warning msg="failed to load hooks: {}%!(EXTRA *os.PathError=open /usr/share/containers/oci/hooks.d: no such file or directory)" With this commit: $ podman --log-level=debug run --rm docker.io/library/alpine echo 'successful container' 2>&1 | grep -i hook time="2018-12-02T21:33:07-08:00" level=debug msg="reading hooks from /usr/share/containers/oci/hooks.d" time="2018-12-02T21:33:07-08:00" level=debug msg="reading hooks from /etc/containers/oci/hooks.d" time="2018-12-02T21:33:07-08:00" level=debug msg="added hook /etc/containers/oci/hooks.d/test.json" time="2018-12-02T21:33:07-08:00" level=debug msg="hook test.json matched; adding to stages [prestart]" time="2018-12-02T21:33:07-08:00" level=warning msg="implicit hook directories are deprecated; set --hooks-dir="/etc/containers/oci/hooks.d" explicitly to continue to load hooks from this directory" time="2018-12-02T21:33:07-08:00" level=error msg="container create failed: container_linux.go:336: starting container process caused "process_linux.go:399: container init caused \"process_linux.go:382: running prestart hook 0 caused \\\"error running hook: exit status 1, stdout: , stderr: oh, noes!\\\\n\\\"\"" (I'd setup the hook to error out). You can see that it's silenly ignoring the ENOENT for /usr/share/containers/oci/hooks.d and continuing on to load hooks from /etc/containers/oci/hooks.d. When it loads the hook, it also logs a warning-level message suggesting that callers explicitly configure their hook directories. That will help consumers migrate, so we can drop the implicit hook directories in some future release. When folks *do* explicitly configure hook directories (via the newly-public --hooks-dir and hooks_dir options), we error out if they're missing: $ podman --hooks-dir /does/not/exist run --rm docker.io/library/alpine echo 'successful container' error setting up OCI Hooks: open /does/not/exist: no such file or directory I've dropped the trailing "path" from the old, hidden --hooks-dir-path and hooks_dir_path because I think "dir(ectory)" is already enough context for "we expect a path argument". I consider this name change non-breaking because the old forms were undocumented. Coming back to rootless users, I've enabled hooks now. I expect they were previously disabled because users had no way to avoid /usr/share/containers/oci/hooks.d which might contain hooks that required root permissions. But now rootless users will have to explicitly configure hook directories, and since their default config is from ~/.config/containers/libpod.conf, it's a misconfiguration if it contains hooks_dir entries which point at directories with hooks that require root access. We error out so they can fix their libpod.conf. [1]: https://github.com/containers/libpod/pull/1487#discussion_r218149355 Signed-off-by: W. Trevor King <wking@tremily.us>

| * 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.

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.

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.
