* generate systemd: create pod templateValentin Rothberg2020-06-11
| | | | | | | | | | Create a new template for generating a pod unit file. Eventually, this allows for treating and extending pod and container generation seprately. The `--new` flag now also works on pods. Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
* generate systemd: refactorValentin Rothberg2020-06-11
| | | | | | | | | | | | Refactor the systemd-unit generation code and move all the logic into `pkg/systemd/generate`. The code was already hard to maintain but I found it impossible to wire the `--new` logic for pods in all the chaos. The code refactoring in this commit will make maintaining the code easier and should make it easier to extend as well. Further changes and refactorings may still be needed but they will easier.

* pod create: add `--infra-conmon-pidfile`Valentin Rothberg2020-06-11
| | | | | | | | | | | Add an `--infra-conmon-pidfile` flag to `podman-pod-create` to write the infra container's conmon process ID to a specified path. Several container sub-commands already support `--conmon-pidfile` which is especially helpful to allow for systemd to access and track the conmon processes. This allows for easily tracking the conmon process of a pod's infra container. Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
* pod config: add a `CreateCommand` fieldValentin Rothberg2020-06-11
| | | | | | | | | | | | | | Add a `CreateCommand` field to the pod config which includes the entire `os.Args` at pod-creation. Similar to the already existing field in a container config, we need this information to properly generate generic systemd unit files for pods. It's a prerequisite to support the `--new` flag for pods. Also add the `CreateCommand` to the pod-inspect data, which can come in handy for debugging, general inspection and certainly for the tests that are added along with the other changes.

* Ensure Conmon is alive before waiting for exit fileMatthew Heon2020-06-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This came out of a conversation with Valentin about systemd-managed Podman. He discovered that unit files did not properly handle cases where Conmon was dead - the ExecStopPost `podman rm --force` line was not actually removing the container, but interestingly, adding a `podman cleanup --rm` line would remove it. Both of these commands do the same thing (minus the `podman cleanup --rm` command not force-removing running containers). Without a running Conmon instance, the container process is still running (assuming you killed Conmon with SIGKILL and it had no chance to kill the container it managed), but you can still kill the container itself with `podman stop` - Conmon is not involved, only the OCI Runtime. (`podman rm --force` and `podman stop` use the same code to kill the container). The problem comes when we want to get the container's exit code - we expect Conmon to make us an exit file, which it's obviously not going to do, being dead. The first `podman rm` would fail because of this, but importantly, it would (after failing to retrieve the exit code correctly) set container status to Exited, so that the second `podman cleanup` process would succeed. To make sure the first `podman rm --force` succeeds, we need to catch the case where Conmon is already dead, and instead of waiting for an exit file that will never come, immediately set the Stopped state and remove an error that can be caught and handled.

* Ensure that containers in pods properly set hostnameMatthew Heon2020-06-04
| | | | | | | | | | | | | | | | | | When we moved to the new Namespace types in Specgen, we made a distinction between taking a namespace from a pod, and taking it from another container. Due to this new distinction, some code that previously worked for both `--pod=$ID` and `--uts=container:$ID` has accidentally become conditional on only the latter case. This happened for Hostname - we weren't properly setting it in cases where the container joined a pod. Fortunately, this is an easy fix once we know to check the condition. Also, ensure that `podman pod inspect` actually prints hostname. Fixes #6494 Signed-off-by: Matthew Heon <matthew.heon@pm.me>

| * Properly follow linked namespace container for statsMatthew Heon2020-06-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Podman containers can specify that they get their network namespace from another container. This is automatic in pods, but any container can do it. The problem is that these containers are not guaranteed to have a network namespace of their own; it is perfectly valid to join the network namespace of a --net=host container, and both containers will end up in the host namespace. The code for obtaining network stats did not account for this, and could cause segfaults as a result. Fortunately, the fix is simple - the function we use to get said stats already performs appropriate checks, so we just need to recursively call it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The biggest obstacle here was cleanup - we needed a way to remove detached exec sessions after they exited, but there's no way to tell if an exec session will be attached or detached when it's created, and that's when we must add the exit command that would do the removal. The solution was adding a delay to the exit command (5 minutes), which gives sufficient time for attached exec sessions to retrieve the exit code of the session after it exits, but still guarantees that they will be removed, even for detached sessions. This requires Conmon 2.0.17, which has the new `--exit-delay` flag. As part of the exit command rework, we can drop the hack we were using to clean up exec sessions (remove them as part of inspect). This is a lot cleaner, and I'm a lot happier about it. Otherwise, this is just plumbing - we need a bindings call for detached exec, and that needed to be added to the tunnel mode backend for entities. Signed-off-by: Matthew Heon <matthew.heon@pm.me>

* compat handlers: add X-Registry-Auth header supportValentin Rothberg2020-05-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Support the `X-Registry-Auth` http-request header. * The content of the header is a base64 encoded JSON payload which can either be a single auth config or a map of auth configs (user+pw or token) with the corresponding registries being the keys. Vanilla Docker, projectatomic Docker and the bindings are transparantly supported. * Add a hidden `--registries-conf` flag. Buildah exposes the same flag, mostly for testing purposes. * Do all credential parsing in the client (i.e., `cmd/podman`) pass the username and password in the backend instead of unparsed credentials. * Add a `pkg/auth` which handles most of the heavy lifting. * Go through the authentication-handling code of most commands, bindings and endpoints. Migrate them to the new code and fix issues as seen. A final evaluation and more tests is still required *after* this change. * The manifest-push endpoint is missing certain parameters and should use the ABI function instead. Adding auth-support isn't really possible without these parts working. * The container commands and endpoints (i.e., create and run) have not been changed yet. The APIs don't yet account for the authfile. * Add authentication tests to `pkg/bindings`. Fixes: #6384 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

Exit commands are presently only used for detached exec, but theoretically could be turned on for all exec sessions if we wanted (I'm declining to do this because of potential overhead). I also forgot to copy the exit command from the exec config into the ExecOptions struct used by the OCI runtime, so it was not being added. There are also two significant bugfixes for exec in here. One is for updating the status of running exec sessions - this was always failing as I had coded it to remove the exit file *before* reading it, instead of after (oops). The second was that removing a running exec session would always fail because I inverted the check to see if it was running. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* | | Add ability to clean up exec sessions with cleanupMatthew Heon2020-05-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We need to be able to use cleanup processes to remove exec sessions as part of detached exec. This PR adds that ability. A new flag is added to `podman container cleanup`, `--exec`, to specify an exec session to be cleaned up. As part of this, ensure that `ExecCleanup` can clean up exec sessions that were running, but have since exited. This ensures that we can come back to an exec session that was running but has since stopped, and clean it up. Signed-off-by: Matthew Heon <matthew.heon@pm.me>

* | Prune stale exec sessions on inspectMatthew Heon2020-05-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The usual flow for exec is going to be: - Create exec session - Start and attach to exec session - Exec session exits, attach session terminates - Client does an exec inspect to pick up exit code The safest point to remove the exec session, without doing any database changes to track stale sessions, is to remove during the last part of this - the single inspect after the exec session exits. This is definitely different from Docker (which would retain the exec session for up to 10 minutes after it exits, where we will immediately discard) but should be close enough to be not noticeable in regular usage.

* | Remove exec sessions on container restartMatthew Heon2020-05-14
| | | | | | | | | | | | | | | | | | | | | | | | | | With APIv2, we cannot guarantee that exec sessions will be removed cleanly on exit (Docker does not include an API for removing exec sessions, instead using a timer-based reaper which we cannot easily replicate). This is part 1 of a 2-part approach to providing a solution to this. This ensures that exec sessions will be reaped, at the very least, on container restart, which takes care of any that were not properly removed during the run of a container.
