* Remove dependency on github.com/opencontainers/libpod/configsDaniel J Walsh2020-07-09
| | | | | | | | | We are using these dependencies just to get the device from path. These dependencies no longer build on Windows, so simply cloning the deviceFromPath function, we can eliminate the need for this vendoring. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>

* Implement --sdnotify cmdline option to control sd-notify behaviorJoseph Gooch2020-07-06
| | | | | | | | | | | | | | | | | | | --sdnotify container|conmon|ignore With "conmon", we send the MAINPID, and clear the NOTIFY_SOCKET so the OCI runtime doesn't pass it into the container. We also advertise "ready" when the OCI runtime finishes to advertise the service as ready. With "container", we send the MAINPID, and leave the NOTIFY_SOCKET so the OCI runtime passes it into the container for initialization, and let the container advertise further metadata. This is the default, which is closest to the behavior podman has done in the past. The "ignore" option removes NOTIFY_SOCKET from the environment, so neither podman nor any child processes will talk to systemd. This removes the need for hardcoded CID and PID files in the command line, and the PIDFile directive, as the pid is advertised directly through sd-notify.

* | move go module to v2Valentin Rothberg2020-07-06
|/ | | | | | | | | | | | | | | With the advent of Podman 2.0.0 we crossed the magical barrier of go modules. While we were able to continue importing all packages inside of the project, the project could not be vendored anymore from the outside. Move the go module to new major version and change all imports to `github.com/containers/libpod/v2`. The renaming of the imports was done via `gomove` [1].

* Allow empty host port in --publish flagMatthew Heon2020-06-29
| | | | | | | | | | | | | | | | | I didn't believe that this was actually legal, but it looks like it is. And, unlike our previous understanding (host port being empty means just use container port), empty host port actually carries the same meaning as `--expose` + `--publish-all` (that is, assign a random host port to the given container port). This requires a significant rework of our port handling code to handle this new case. I don't foresee this being commonly used, so I optimized having a fixed port number as fast path, which this random assignment code running after the main port handling code only if necessary.

* specgen: fix order for setting rlimitsRalf Haferkamp2020-06-26
| | | | | | | | | | | | Also make sure that the limits we set for rootless are not higher than what we'd set for root containers. Rootless containers failed to start when the calling user already had ulimit (e.g. on NOFILE) set.

* Set syslog for exit commands on log-level=debugMatthew Heon2020-06-24
| | | | | | | | | | | | | | | | We have a flag, --syslog, for telling logrus to log to syslog as well as to the terminal. Previously, this flag also set the exit command for containers to use `--syslog` (otherwise all output from exit commands is lost). I attempted to replicate this with Podman v2.0, but quickly ran into circular import hell (the flag is defined in cmd/podman, I needed it in cmd/podman/containers, cmd/podman imports cmd/podman/containers already, etc). Instead, let's just set the syslog flag automatically on `--log-level=debug` so we log exit commands automatically when debug-level logs are requested. This is consistent with Conmon and seems to make sense. Signed-off-by: Matthew Heon <matthew.heon@pm.me>

* Add support for the unless-stopped restart policyMatthew Heon2020-06-17
| | | | | | | | | | | | | | | | | | We initially believed that implementing this required support for restarting containers after reboot, but this is not the case. The unless-stopped restart policy acts identically to the always restart policy except in cases related to reboot (which we do not support yet), but it does not require that support for us to implement it. Changes themselves are quite simple, we need a new restart policy constant, we need to remove existing checks that block creation of containers when unless-stopped was used, and we need to update the manpages.

| * Re-add resource limit warnings to SpecgenMatthew Heon2020-06-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These were part of Podman v1.9, but were lost in the transition to using Specgen to create containers. Most resource limits are checked via the sysinfo package to ensure they are safe to use (the cgroup is mounted, kernel support is present, etc) and removed if not safe. Further, bounds checks are performed to ensure that values are valid. Ensure these warnings are printed client-side when they occur. This part is a little bit gross, as it happens in pkg/infra and not cmd/podman, which is largely down to how we implemented `podman run` - all the work is done in pkg/infra and it returns only once the container has exited, and we need warnings to print *before* the container runs. The solution here, while inelegant, avoid the need to extensively refactor our handling of run. Should fix blkio-limit warnings that were identified by the FCOS test suite.

* 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 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>

* Enable detached exec for remoteMatthew Heon2020-06-02
| | | | | | | | | | | | | | | | | | | | | | | 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>

* Enable cleanup processes for detached execMatthew Heon2020-05-20
| | | | | | | | | | | | | | | | | | | | | | The cleanup command creation logic is made public as part of this and wired such that we can call it both within SpecGen (to make container exit commands) and from the ABI detached exec handler. 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 small fixes for 'podman run' from diffing inspectMatthew Heon2020-05-05
| | | | | | | | | | | | | | | | | | | | | | | | To try and identify differences between Podman v1.9 and master, I ran a series of `podman run` commands with various flags through each, then inspecting the resulting containers and diffed the inspect JSON between each. This identified a number of issues which are fixed in this PR. In order of discovery: - Podman v2 gave short names for images, where Podman v1 gave the fully-qualified name. Simple enough fix (get image tags and use the first one if they're available) - The --restart flag was not being parsed correctly when a number of retries was specified. Parsing has been corrected. - The -m flag was not setting the swap limit (simple fix to set swap in that case if it's not explicitly set by the user) - The --cpus flag was completely nonfunctional (wired in its logic) Tests have been added for all of these to catch future regressions.

* Rework port parsing to support --expose and -PMatthew Heon2020-05-04
| | | | | | | | | | | | | | | | | | | | | As part of this, make a major change to the type we use to represent port mappings in SpecGen (from using existing OCICNI structs to using our own custom one). This struct has the advantage of supporting ranges, massively reducing traffic over the wire for Podman commands using them (for example, the `podman run -p 5000-6000` command will now send only one struct instead of 1000). This struct also allows us to easily validate which ports are in use, and which are not, which is necessary for --expose. Once we have parsed the ports from the new struct, we can produce an accurate map including all currently requested ports, and use that to determine what ports need to be exposed (some requested exposed ports may already be included in a mapping from --publish and will be ignored) and what open ports on the host we can map them to.
