* Drop default log-level from error to warnDaniel J Walsh2020-12-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Our users are missing certain warning messages that would make debugging issues with Podman easier. For example if you do a podman build with a Containerfile that contains the SHELL directive, the Derective is silently ignored. If you run with the log-level warn you get a warning message explainging what happened. $ podman build --no-cache -f /tmp/Containerfile1 /tmp/ STEP 1: FROM ubi8 STEP 2: SHELL ["/bin/bash", "-c"] STEP 3: COMMIT --> 7a207be102a 7a207be102aa8993eceb32802e6ceb9d2603ceed9dee0fee341df63e6300882e $ podman --log-level=warn build --no-cache -f /tmp/Containerfile1 /tmp/ STEP 1: FROM ubi8 STEP 2: SHELL ["/bin/bash", "-c"] STEP 3: COMMIT WARN[0000] SHELL is not supported for OCI image format, [/bin/bash -c] will be ignored.

* 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>

* | 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].

* Ensure `podman inspect` output for NetworkMode is rightMatthew Heon2020-05-08
| | | | | | | | | | | 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`. At the same time, realized that we actually store whether Slirp is in use, so we can be more specific than just "default" and instead say slirp4netns or bridge.

* 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>
* add {generate,play} kubeValentin Rothberg2020-05-06
| | | | | | | | | | | | | | | | | | | Add the `podman generate kube` and `podman play kube` command. The code has largely been copied from Podman v1 but restructured to not leak the K8s core API into the (remote) client. Both commands are added in the same commit to allow for enabling the tests at the same time. Move some exports from `cmd/podman/common` to the appropriate places in the backend to avoid circular dependencies. Move definitions of label annotations to `libpod/define` and set the security-opt labels in the frontend to make kube tests pass. Implement rest endpoints, bindings and the tunnel interface.

| | | | | | | | | | | | | | | | When inspecting containers, info on CNI networks added to the container by name (e.g. --net=name1) should be displayed separately from the configuration of the default network, in a separate map called Networks. This patch adds this separation, improving our Docker compatibility and also adding the ability to see if a container has more than one IPv4 and IPv6 address and more than one MAC address.

* Ensure SizeRw is shown when a user does 'inspect --size -t container'.Neville Cain2019-12-27
| | | | | | | | | | | | | | Currently, if a user requests the size on a container (inspect --size -t container), the SizeRw does not show up if the value is 0. It's because InspectContainerData is defined as int64 and there is an omit when empty. We do want to display it even if the value is empty. I have changed the type of SizeRw to be a pointer to an int64 instead of an int64. It will allow us todistinguish the empty value to the missing value. I updated the test "podman inspect container with size" to ensure we check thatSizeRw is displayed correctly. Closes #4744 Signed-off-by: NevilleC <neville.cain@qonto.eu>
* container config: add CreateCommandValentin Rothberg2019-12-13
| | | | | | | | | | | | | | | | | | Store the full command plus arguments of the process the container has been created with. Expose this data as a `Config.CreateCommand` field in the container-inspect data as well. This information can be useful for debugging, as we can find out which command has created the container, and, if being created via the Podman CLI, we know exactly with which flags the container has been created with. The immediate motivation for this change is to use this information for `podman-generate-systemd` to generate systemd-service files that allow for creating new containers (in contrast to only starting existing ones).

* inspect: rename ImageID go field to ImageValentin Rothberg2019-10-15
| | | | | | | | | | | | | | The json field is called `Image` while the go field is called `ImageID`, tricking users into filtering for `Image` which ultimately results in an error. Hence, rename the field to `Image` to align json and go. To prevent podman users from regressing, rename `Image` to `ImageID` in the specified filters. Add tests to prevent us from regressing. Note that consumers of the go API that are using `ImageID` are regressing; ultimately we consider it to be a bug fix. Fixes: #4193 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

* Move the HostConfig portion of Inspect inside libpodMatthew Heon2019-07-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we first began writing Podman, we ran into a major issue when implementing Inspect. Libpod deliberately does not tie its internal data structures to Docker, and stores most information about containers encoded within the OCI spec. However, Podman must present a CLI compatible with Docker, which means it must expose all the information in 'docker inspect' - most of which is not contained in the OCI spec or libpod's Config struct. Our solution at the time was the create artifact. We JSON'd the complete CreateConfig (a parsed form of the CLI arguments to 'podman run') and stored it with the container, restoring it when we needed to run commands that required the extra info. Over the past month, I've been looking more at Inspect, and refactored large portions of it into Libpod - generating them from what we know about the OCI config and libpod's (now much expanded, versus previously) container configuration. This path comes close to completing the process, moving the last part of inspect into libpod and removing the need for the create artifact. This improves libpod's compatability with non-Podman containers. We no longer require an arbitrarily-formatted JSON blob to be present to run inspect.
