* Do not store the exit command in container configPaul Holzinger2021-11-18
| | | | | | | | | | | | | | | | | | | There is a problem with creating and storing the exit command when the container was created. It only contains the options the container was created with but NOT the options the container is started with. One example would be a CNI network config. If I start a container once, then change the cni config dir with `--cni-config-dir` ans start it a second time it will start successfully. However the exit command still contains the wrong `--cni-config-dir` because it was not updated. To fix this we do not want to store the exit command at all. Instead we create it every time the conmon process for the container is startet. This guarantees us that the container cleanup process is startet with the correct settings.

* Add --unsetenv & --unsetenv-all to remove def environment variablesDaniel J Walsh2021-11-15
| | | | | | | | | | | | | | | | Podman adds a few environment variables by default, and currently there is no way to get rid of them from your container. This option will allow you to specify which defaults you don't want. --unsetenv-all will remove all default environment variables. Default environment variables can come from podman builtin, containers.conf or from the container image.

| * | podman inspect add State.Health field for docker compatPaul Holzinger2021-09-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | podman inspect shows the healthcheck status in `.State.Healthcheck`, docker uses `.State.Health`. To make sure docker scripts work we should add the `Health` key. Because we do not want to display both keys by default we only use the new `Health` key. This is a breaking change for podman users but matches what docker does. To provide some form of compatibility users can still use `--format {{.State.Healthcheck}}`. IT is just not shown by default.

* podman inspect show exposed portsPaul Holzinger2021-08-24
| | | | | | | | | | | | | | Podman inspect has to show exposed ports to match docker. This requires storing the exposed ports in the container config. A exposed port is shown as `"80/tcp": null` while a forwarded port is shown as `"80/tcp": [{"HostIp": "", "HostPort": "8080" }]`. Also make sure to add the exposed ports to the new image when the container is commited. Fixes #10777 Signed-off-by: Paul Holzinger <pholzing@redhat.com>

* Fix problem copying files when container is in host pid namespaceDaniel J Walsh2021-05-19
| | | | | | | | | | | | | | When attempting to copy files into and out of running containers within the host pidnamespace, the code was attempting to join the host pidns again, and getting an error. This was causing the podman cp command to fail. Since we are already in the host pid namespace, we should not be attempting to join. This PR adds a check to see if the container is in NOT host pid namespace, and only then attempts to join.

| | | | | | | | | | | When doing a container inspect on a container with unlimited ulimits, the value should be -1.

* Initial implementation of volume pluginsMatthew Heon2021-01-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This implements support for mounting and unmounting volumes backed by volume plugins. Support for actually retrieving plugins requires a pull request to land in containers.conf and then that to be vendored, and as such is not yet ready. Given this, this code is only compile tested. However, the code for everything past retrieving the plugin has been written - there is support for creating, removing, mounting, and unmounting volumes, which should allow full functionality once the c/common PR is merged. A major change is the signature of the MountPoint function for volumes, which now, by necessity, returns an error. Named volumes managed by a plugin do not have a mountpoint we control; instead, it is managed entirely by the plugin. As such, we need to cache the path in the DB, and calls to retrieve it now need to access the DB (and may fail as such). Notably absent is support for SELinux relabelling and chowning these volumes. Given that we don't manage the mountpoint for these volumes, I am extremely reluctant to try and modify it - we could easily break the plugin trying to chown or relabel it. Also, we had no less than *5* separate implementations of inspecting a volume floating around in pkg/infra/abi and pkg/api/handlers/libpod. And none of them used volume.Inspect(), the only correct way of inspecting volumes. Remove them all and consolidate to using the correct way. Compat API is likely still doing things the wrong way, but that is an issue for another day. Fixes #4304 Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* Exorcise Driver code from libpod/defineMatthew Heon2021-01-12
| | | | | | | | | | | | The libpod/define code should not import any large dependencies, as it is intended to be structures and definitions only. It included the libpod/driver package for information on the storage driver, though, which brought in all of c/storage.

* new "image" mount typeValentin Rothberg2020-10-29
| | | | | | | | | | | | | | Add a new "image" mount type to `--mount`. The source of the mount is the name or ID of an image. The destination is the path inside the container. Image mounts further support an optional `rw,readwrite` parameter which if set to "true" will yield the mount writable inside the container. Note that no changes are propagated to the image mount on the host (which in any case is read only). Mounts are overlay mounts. To support read-only overlay mounts, vendor a non-release version of Buildah. Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
* Store cgroup manager on a per-container basisMatthew Heon2020-10-08
| | | | | | | | | | | | | | | | | | | | | When we create a container, we assign a cgroup parent based on the current cgroup manager in use. This parent is only usable with the cgroup manager the container is created with, so if the default cgroup manager is later changed or overridden, the container will not be able to start. To solve this, store the cgroup manager that created the container in container configuration, so we can guarantee a container with a systemd cgroup parent will always be started with systemd cgroups. Unfortunately, this is very difficult to test in CI, due to the fact that we hard-code cgroup manager on all invocations of Podman in CI. Fixes #7830 Signed-off-by: Matthew Heon <matthew.heon@pm.me>

| | | | | | | | | | | I realized that setting NetworkMode to private when we are making a network namespace but not configuring it with CNI or Slirp is wrong; that's considered `--net=none` not `--net=private`.

* Fix bug where pods would unintentionally share cgroupnsMatthew Heon2020-05-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This one was a massive pain to track down. The original symptom was an error message from rootless Podman trying to make a container in a pod. I unfortunately did not look at the error message closely enough to realize that the namespace in question was the cgroup namespace (the reproducer pod was explicitly set to only share the network namespace), else this would have been quite a bit shorter. I spent considerable effort trying to track down differences between the inspect output of the two containers, and when that failed I was forced to resort to diffing the OCI specs. That finally proved fruitful, and I was able to determine what should have been obvious all along: the container was joining the cgroup namespace of the infra container when it really ought not to have. From there, I discovered a variable collision in pod config. The UsePodCgroup variable means "create a parent cgroup for the pod and join containers in the pod to it". Unfortunately, it is very similar to UsePodUTS, UsePodNet, etc, which mean "the pod shares this namespace", so an accessor was accidentally added for it that indicated the pod shared the cgroup namespace when it really did not. Once I realized that, it was a quick fix - add a bool to the pod's configuration to indicate whether the cgroup ns was shared (distinct from UsePodCgroup) and use that for the accessor. Also included are fixes for `podman inspect` and `podman pod inspect` that fix them to actually display the state of the cgroup namespace (for container inspect) and what namespaces are shared (for pod inspect). Either of those would have made tracking this down considerably quicker. Fixes #6149 Signed-off-by: Matthew Heon <mheon@redhat.com>
