* Add binding options for container|pod existsbaude2021-01-18
| | | | | | | | It turns out an options was added to container exists so it makes sense to have pods and container exists calls have an optional structure for options. Signed-off-by: baude <bbaude@redhat.com>

* Initial implementation of renaming containersMatthew Heon2021-01-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Basic theory: We remove the container, but *only from the DB*. We leave it in c/storage, we leave the lock allocated, we leave it running (if it is). Then we create an identical container with an altered name, and add that back to the database. Theoretically we now have a renamed container. The advantage of this approach is that it doesn't just apply to rename - we can use this to make *any* configuration change to a container that does not alter its container ID. Potential problems are numerous. This process is *THOROUGHLY* non-atomic at present - if you `kill -9` Podman mid-rename things will be in a bad place, for example. Also, we can't rename containers that can't be removed normally - IE, containers with dependencies (pod infra containers, for example). The largest potential improvement will be to move the majority of the work into the DB, with a `RecreateContainer()` method - that will add atomicity, and let us remove the container without worrying about depencies and similar issues. Potential problems: long-running processes that edit the DB and may have an older version of the configuration around. Most notable example is `podman run --rm` - the removal command needed to be manually edited to avoid this one. This begins to get at the heart of me not wanting to do this in the first place... This provides CLI and API implementations for frontend, but no tunnel implementation. It will be added in a future release (just held back for time now - we need this in 3.0 and are running low on time). This is honestly kind of horrifying, but I think it will work.

* Reduce general binding binary sizebaude2021-01-13

* Rework pruning to report reclaimed spaceBaron Lenardson2020-12-30
| | | | | | | | | | | | This change adds code to report the reclaimed space after a prune. Reclaimed space from volumes, images, and containers is recorded during the prune call in a PruneReport struct. These structs are collected into a slice during a system prune and processed afterwards to calculate the total reclaimed space. Closes #8658 Signed-off-by: Baron Lenardson <lenardson.baron@gmail.com>

| | | | | | | | | | | | | | Implement `podman-remote cp` and break out the logic from the previously added `pkg/copy` into it's basic building blocks and move them up into the `ContainerEngine` interface and `cmd/podman`. The `--pause` and `--extract` flags are now deprecated and turned into nops. Note that this commit is vendoring a non-release version of Buildah to pull in updates to the copier package.

* rewrite podman-cpValentin Rothberg2020-12-04
| | | | | | | | | | | | | | | | | | | | | | | | * Add a new `pkg/copy` to centralize all container-copy related code. * The new code is based on Buildah's `copier` package. * The compat `/archive` endpoints use the new `copy` package. * Update docs and an several new tests. * Includes many fixes, most notably, the look-up of volumes and mounts. Breaking changes: * Podman is now expecting that container-destination paths exist. Before, Podman created the paths if needed. Docker does not do that and I believe Podman should not either as it's a recipe for masking errors. These errors may be user induced (e.g., a path typo), or internal typos (e.g., when the destination may be a mistakenly unmounted volume). Let's keep the magic low for such a security sensitive feature. Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

* The cidfile should be created when the container is createdDaniel J Walsh2020-10-26
| | | | | | | | | | | Currently if you run an interactive session of podman run and specifiy the --cidfile option, the cidfile will not get created until the container finishes running. If you run a detached container, it will get created right away. This Patch creates the cidfile as soon as the container is created. This could allow other tools to use the cidefile on all running containers. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>

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

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

* 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.

* 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.

| * 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.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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