* Fix container and pod create commands for remote createMatthew Heon2020-07-10
| | | | | | | | | | | | | | | | | | | | | | | In `podman inspect` output for containers and pods, we include the command that was used to create the container. This is also used by `podman generate systemd --new` to generate unit files. With remote podman, the generated create commands were incorrect since we sourced directly from os.Args on the server side, which was guaranteed to be `podman system service` (or some variant thereof). The solution is to pass the command along in the Specgen or PodSpecgen, where we can source it from the client's os.Args. This will still be VERY iffy for mixed local/remote use (doing a `podman --remote run ...` on a remote client then a `podman generate systemd --new` on the server on the same container will not work, because the `--remote` flag will slip in) but at the very least the output of `podman inspect` will be correct. We can look into properly handling `--remote` (parsing it out would be a little iffy) in a future PR. Signed-off-by: Matthew Heon <matthew.heon@pm.me>

| | | | | | | | | | If I enter a continer with --userns keep-id, my UID will be present inside of the container, but most likely my user will not be defined. This patch will take information about the user and stick it into the container. 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.

* | podman: add new cgroup mode splitGiuseppe Scrivano2020-06-25
|/ | | | | | | | | | | | | | | | | | | When running under systemd there is no need to create yet another cgroup for the container. With conmon-delegated the current cgroup will be split in two sub cgroups: - supervisor - container The supervisor cgroup will hold conmon and the podman process, while the container cgroup is used by the OCI runtime (using the cgroupfs backend).

* | Set stop signal to 15 when not explicitly setMatthew Heon2020-06-24
|/ | | | | | | | | | | | | | | | When going through the output of `podman inspect` to try and identify another issue, I noticed that Podman 2.0 was setting StopSignal to 0 on containers by default. After chasing it through the command line and SpecGen, I determined that we were actually not setting a default in Libpod, which is strange because I swear we used to do that. I re-added the disappeared default and now all is well again. Also, while I was looking for the bug in SpecGen, I found a bunch of TODOs that have already been done. Eliminate the comments for these.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | Fix podman inspect on overlapping/missing objectsMatthew Heon2020-06-16
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This started as a small fix to `podman inspect` where a container and image, with the same name/tag, were present, and `podman inspect` was run on that name. `podman inspect` in 1.9 (and `docker inspect`) will give you the container; in v2.0, we gave the image. This was an easy fix (just reorder how we check for image/container). Unfortunately, in the process of testing this fix, I determined that we regressed in a different area. When you run inspect on a number of containers, some of which do not exist, `podman inspect` should return an array of inspect results for the objects that exist, then print a number of errors, one for each object that could not be found. We were bailing after the first error, and not printing output for the containers that succeeded. (For reference, this applied to images as well). This required a much more substantial set of changes to properly handle - signatures for the inspect functions in ContainerEngine and ImageEngine, plus the implementations of these interfaces, plus the actual inspect frontend code needed to be adjusted to use this.

* {create,run} --replaceValentin Rothberg2020-06-15
| | | | | | | | | | | | | Add a `--replace` flag to the `container {create,run}` commands. If another container with the same name already exists, it will be replaced and removed. Adding this flag is motivated by #5485 to make running Podman in systemd units (or any other scripts/automation) more robust. In case of a crash, a container may not be removed by a sytemd unit anymore. The `--replace` flag allows for supporting crashes. Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

* | Enable IPv6 port bindingMatthew Heon2020-06-10
|/ | | | | | | | | | | | | | | | | | | | | | | | Two areas needed tweaking to accomplish this: port parsing and binding ports on the host. Parsing is an obvious problem - we have to accomodate an IPv6 address enclosed by [] as well as a normal IPv4 address. It was slightly complicated by the fact that we previously just counted the number of colons in the whole port definition (a thousand curses on whoever in the IPv6 standard body decided to reuse colons for address separators), but did not end up being that bad. Libpod also (optionally) binds ports on the host to prevent their reuse by host processes. This code was IPv4 only for TCP, and bound to both for UDP (which I'm fairly certain is not correct, and has been adjusted). This just needed protocols adjusted to read "tcp4"/"tcp6" and "udp4"/"udp6" based on what we wanted to bind to. Fixes #5715 Signed-off-by: Matthew Heon <matthew.heon@pm.me>

| | | | | | | | | | Systemd enablement has to happen on the server side, since we need check if the image is running systemd.

* Strip defaults from namespace flagsMatthew Heon2020-06-04
| | | | | | | | | | | | | | | | | We were picking up defaults from the client's containers.conf, which broke pod namespaces. The server-side code already checks containers.conf when not explicitly overridden by the user, or by the container being part of a pod (the last bit being our bug). This only manifested on systems with a containers.conf installed, so RHEL 8 and Fedora 32 (which means our F32 CI VMs likely should have caught it, but didn't, which is concerning). This prevents defaults for these flags being shown, but they were incorrect anyways for `podman-remote`, so I'm not terribly concerned. 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.
