|\ | | | | fix podman container exists and diff for storage containers
| * Add support for external containerDaniel J Walsh2020-10-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | External containers are containers created outside of Podman. For example Buildah and CRI-O Containers. $ buildah from alpine alpine-working-container $ buildah run alpine-working-container touch /test $ podman container exists --external alpine-working-container $ podman container diff alpine-working-container C /etc A /test Added --external flag to refer to external containers, rather then --storage. Added --external for podman container exists and modified podman ps to use --external rather then --storage. It was felt that --storage would confuse the user into thinking about changing the storage driver or options. --storage is still supported through the use of aliases. Finally podman contianer diff, does not require the --external flag, since it there is little change of users making the mistake, and would just be a pain for the user to remember the flag. podman container exists --external is required because it could fool scripts that rely on the existance of a Podman container, and there is a potential for a partial deletion of a container, which could mess up existing users.

* Remove excessive error wrappingKir Kolyshkin2020-10-05
| | | | | | | | | | | | | | | | | In case os.Open[File], os.Mkdir[All], ioutil.ReadFile and the like fails, the error message already contains the file name and the operation that fails, so there is no need to wrap the error with something like "open %s failed". While at it - replace a few places with os.Open, ioutil.ReadAll with ioutil.ReadFile. - replace errors.Wrapf with errors.Wrap for cases where there are no %-style arguments.

| | | | | | | | | | | | | | | | Have a clear separation of concerns for the CLI-only options (and their logic) from the backend. The backend logic is now easier to understand (e.g., `stream` instead of `noStream`). Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

| | | | | | | | | | | | | | | | | | Add a new endpoint for container stats allowing for batch operations on more than one container.

| * stats refactorValentin Rothberg2020-09-23
| | | | | | | | | | | | | | | | | | | | | | | | Refactor the entities' stats API to simplify using it and reduce the risk of running into concurrency issues at the call sites. Further simplify the stats code by de-spaghetti-ing the logic and reducing duplicate code. `ContainerStats` now returns a data channel and an error. If the error is nil, callers can read from the channel. Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

* Fix up attach tests for podman remoteDaniel J Walsh2020-09-22
| | | | | | | | | | | When we execute podman-remote attach, we were not checking if the container was in the correct state, this is leading to timeouts and we had turned off remote testing. Also added an IfRemote() function so we can turn on more tests when using the "-l" flag for local, but use container name for remote. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>

* remote run: fix error checksValentin Rothberg2020-09-11
| | | | | | | | | | | | As error types are not preserved on the client side (due to marshaling), we cannot use `errors.Cause(...)` and friends but, unfortunately, have to fall back to looking for substring the error messages. Change the error checks in remote run to do substring matches and fix issue #7340. Fixes: #7340 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
* remote run: consult events for exit codeValentin Rothberg2020-09-10
| | | | | | | | | | | | | | | | After attaching to a container, we wait for the container to finish and return its exit code. Waiting for the container may not always succeed, for instance, when the container has been force removed by another process. In such case, we have to look at the *last* container-exit event. Also refactor the `ContainerRun` method a bit to return early on errors and de-spaghetti the code. Enable the remote-disabled system test. Fixes: #7117 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
* Unconditionally retrieve pod names via APIMatthew Heon2020-08-10
| | | | | | | | | | | | | | | | | | The ListContainers API previously had a Pod parameter, which determined if pod name was returned (but, notably, not Pod ID, which was returned unconditionally). This was fairly confusing, so we decided to deprecate/remove the parameter and return it unconditionally. To do this without serious performance implications, we need to avoid expensive JSON decodes of pod configuration in the DB. The way our Bolt tables are structured, retrieving name given ID is actually quite cheap, but we did not expose this via the Libpod API. Add a new GetName API to do this.

* Handle podman-remote run --rmDaniel J Walsh2020-08-04
| | | | | | | | We need to remove the container after it has exited for podman-remote run --rm commands. If we don't remove this container at this step, we open ourselves up to race conditions. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>

* 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].

|\ | | | | Re-add resource limit warnings to Specgen
| * 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.

|\ \ | | | | | | Fix podman inspect on overlapping/missing objects
| * | 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.

* Add parallel operation to `podman stop`Matthew Heon2020-06-05
| | | | | | | | | | | | This is the other command that benefits greatly from being run in parallel, due to the potential 15-second timeout for containers that ignore SIGTERM. While we're at it, also clean up how stop timeout is set. This needs to be an optional parameter, so that the value set when the container is created with `--stop-timeout` will be respected.

* 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>
* Add bindings for exec and enable attached remoteMatthew Heon2020-06-01
| | | | | | | | | | | This adds bindings for starting exec sessions, and then uses them to wire up detached exec. Code is heavily based on Attach code for containers, slightly modified to handle exec sessions. Bindings are presently attached-only, detached is pending on a Conmon update landing in CI. I'll probably get to that next. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
