* | Docker-compose disable healthcheck properly handledJake Correnti2022-07-05
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, if a container had healthchecks disabled in the docker-compose.yml file and the user did a `podman inspect <container>`, they would have an incorrect output: ``` "Healthcheck":{ "Test":[ "CMD-SHELL", "NONE" ], "Interval":30000000000, "Timeout":30000000000, "Retries":3 } ``` After a quick change, the correct output is now the result: ``` "Healthcheck":{ "Test":[ "NONE" ] } ``` Additionally, I extracted the hard-coded strings that were used for comparisons into constants in `libpod/define` to prevent a similar issue from recurring.

| * | add podman volume reload to sync volume pluginsPaul Holzinger2022-06-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Libpod requires that all volumes are stored in the libpod db. Because volume plugins can be created outside of podman, it will not show all available plugins. This podman volume reload command allows users to sync the libpod db with their external volume plugins. All new volumes from the plugin are also created in the libpod db and when a volume from the db no longer exists it will be removed if possible. There are some problems: - naming conflicts, in this case we only use the first volume we found. This is not deterministic. - race conditions, we have no control over the volume plugins. It is possible that the volumes changed while we run this command. Fixes #14207 Signed-off-by: Paul Holzinger <pholzing@redhat.com>
* | | libpod: fix wait and exit-code logicValentin Rothberg2022-06-23
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit addresses three intertwined bugs to fix an issue when using Gitlab runner on Podman. The three bug fixes are not split into separate commits as tests won't pass otherwise; avoidable noise when bisecting future issues. 1) Podman conflated states: even when asking to wait for the `exited` state, Podman returned as soon as a container transitioned to `stopped`. The issues surfaced in Gitlab tests to fail [1] as `conmon`'s buffers have not (yet) been emptied when attaching to a container right after a wait. The race window was extremely narrow, and I only managed to reproduce with the Gitlab runner [1] unit tests. 2) The clearer separation between `exited` and `stopped` revealed a race condition predating the changes. If a container is configured for autoremoval (e.g., via `run --rm`), the "run" process competes with the "cleanup" process running in the background. The window of the race condition was sufficiently large that the "cleanup" process has already removed the container and storage before the "run" process could read the exit code and hence waited indefinitely. Address the exit-code race condition by recording exit codes in the main libpod database. Exit codes can now be read from a database. When waiting for a container to exit, Podman first waits for the container to transition to `exited` and will then query the database for its exit code. Outdated exit codes are pruned during cleanup (i.e., non-performance critical) and when refreshing the database after a reboot. An exit code is considered outdated when it is older than 5 minutes. While the race condition predates this change, the waiting process has apparently always been fast enough in catching the exit code due to issue 1): `exited` and `stopped` were conflated. The waiting process hence caught the exit code after the container transitioned to `stopped` but before it `exited` and got removed. 3) With 1) and 2), Podman is now waiting for a container to properly transition to the `exited` state. Some tests did not pass after 1) and 2) which revealed the third bug: `conmon` was executed with its working directory pointing to the OCI runtime bundle of the container. The changed working directory broke resolving relative paths in the "cleanup" process. The "cleanup" process error'ed before actually cleaning up the container and waiting "main" process ran indefinitely - or until hitting a timeout. Fix the issue by executing `conmon` with the same working directory as Podman. Note that fixing 3) *may* address a number of issues we have seen in the past where for *some* reason cleanup processes did not fire.

* play kube: service containerValentin Rothberg2022-05-12
| | | | | | | | | | | | | | | | | | | | Add the notion of a "service container" to play kube. A service container is started before the pods in play kube and is (reverse) linked to them. The service container is stopped/removed *after* all pods it is associated with are stopped/removed. In other words, a service container tracks the entire life cycle of a service started via `podman play kube`. This is required to enable `play kube` in a systemd unit file. The service container is only used when the `--service-container` flag is set on the CLI. This flag has been marked as hidden as it is not meant to be used outside the context of `play kube`. It is further not supported on the remote client. The wiring with systemd will be done in a later commit. Signed-off-by: Valentin Rothberg <vrothberg@redhat.com>

* pod: add exit policiesValentin Rothberg2022-05-02
| | | | | | | | | | | | | | | | | | | | | | | | Add the notion of an "exit policy" to a pod. This policy controls the behaviour when the last container of pod exits. Initially, there are two policies: - "continue" : the pod continues running. This is the default policy when creating a pod. - "stop" : stop the pod when the last container exits. This is the default behaviour for `play kube`. In order to implement the deferred stop of a pod, add a worker queue to the libpod runtime. The queue will pick up work items and in this case helps resolve dead locks that would otherwise occur if we attempted to stop a pod during container cleanup. Note that the default restart policy of `play kube` is "Always". Hence, in order to really solve #13464, the YAML files must set a custom restart policy; the tests use "OnFailure".

* | enable gocritic linterPaul Holzinger2022-04-26
|/ | | | | | | | | | | | | | | | | | | | | | The linter ensures a common code style. - use switch/case instead of else if - use if instead of switch/case for single case statement - add space between comment and text - detect the use of defer with os.Exit() - use short form var += "..." instead of var = var + "..." - detect problems with append() ``` newSlice := append(orgSlice, val) ``` This could lead to nasty bugs because the orgSlice will be changed in place if it has enough capacity too hold the new elements. Thus we newSlice might not be a copy. Of course most of the changes are just cosmetic and do not cause any logic errors but I think it is a good idea to enforce a common style. This should help maintainability. Signed-off-by: Paul Holzinger <pholzing@redhat.com>

* Add support for checkpoint imageRadostin Stoyanov2022-04-20
| | | | | | | | | | | | | | | | | | | | | | | | This is an enhancement proposal for the checkpoint / restore feature of Podman that enables container migration across multiple systems with standard image distribution infrastructure. A new option `--create-image <image>` has been added to the `podman container checkpoint` command. This option tells Podman to create a container image. This is a standard image with a single layer, tar archive, that that contains all checkpoint files. This is similar to the current approach with checkpoint `--export`/`--import`. This image can be pushed to a container registry and pulled on a different system. It can also be exported locally with `podman image save` and inspected with `podman inspect`. Inspecting the image would display additional information about the host and the versions of Podman, criu, crun/runc, kernel, etc. `podman container restore` has also been extended to support image name or ID as input.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Improve our compatibility with Docker by better handling the state strings that we print in `podman ps`. Docker capitalizes all states in `ps` (we do not) - fix this in our PS code. Also, stop normalizing ContainerStateConfigured to the "Created" state, and instead make it always be Created, with the existing Created state becoming Initialized. I didn't rename the actual states because I'm somewhat reticent to make such a large change a day before we leave for break. It's somewhat confusing that ContainerStateConfigured now returns Created, but internally and externally we're still consistent. [NO NEW TESTS NEEDED] existing tests should catch anything that broke. I also consider this a breaking change. I will flag appropriately on Github. Fixes RHBZ#2010432 and RHBZ#2032561 Signed-off-by: Matthew Heon <mheon@redhat.com>

* | 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.

* Added optional container checkpointing statisticsAdrian Reber2021-11-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the parameter '--print-stats' to 'podman container checkpoint'. With '--print-stats' Podman will measure how long Podman itself, the OCI runtime and CRIU requires to create a checkpoint and print out these information. CRIU already creates checkpointing statistics which are just read in addition to the added measurements. In contrast to just printing out the ID of the checkpointed container, Podman will now print out JSON: # podman container checkpoint --latest --print-stats { "podman_checkpoint_duration": 360749, "container_statistics": [ { "Id": "25244244bf2efbef30fb6857ddea8cb2e5489f07eb6659e20dda117f0c466808", "runtime_checkpoint_duration": 177222, "criu_statistics": { "freezing_time": 100657, "frozen_time": 60700, "memdump_time": 8162, "memwrite_time": 4224, "pages_scanned": 20561, "pages_written": 2129 } } ] } The output contains 'podman_checkpoint_duration' which contains the number of microseconds Podman required to create the checkpoint. The output also includes 'runtime_checkpoint_duration' which is the time the runtime needed to checkpoint that specific container. Each container also includes 'criu_statistics' which displays the timing information collected by CRIU. Signed-off-by: Adrian Reber <areber@redhat.com>
