* | test: use `T.TempDir` to create temporary test directoryEng Zer Jun2022-05-05
|/ | | | | | | | | | | | | | | | | | | This commit replaces `ioutil.TempDir` with `t.TempDir` in tests. The directory created by `t.TempDir` is automatically removed when the test and all its subtests complete. Prior to this commit, temporary directory created using `ioutil.TempDir` needs to be removed manually by calling `os.RemoveAll`, which is omitted in some tests. The error handling boilerplate e.g. defer func() { if err := os.RemoveAll(dir); err != nil { t.Fatal(err) } } is also tedious, but `t.TempDir` handles this for us nicely.

* 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>
* replace golint with revive linterPaul Holzinger2022-04-22
| | | | | | | | | | | | golint, scopelint and interfacer are deprecated. golint is replaced by revive. This linter is better because it will also check for our error style: `error strings should not be capitalized or end with punctuation or a newline` scopelint is replaced by exportloopref (already endabled) interfacer has no replacement but I do not think this linter is important.

* Remove error stutterDaniel J Walsh2022-03-25
| | | | | | | | | | | | | | | | | When podman gets an error it prints out "Error: " before printing the error string. If the error message starts with error, we end up with Error: error ... This PR Removes all of these stutters. logrus.Error() also prints out that this is an error, so no need for the error stutter. [NO NEW TESTS NEEDED] Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>

Previously, only the size computation was optional, now the one for the parent image is as well. In many cases, the parent image is not needed but it takes around 10ms on my local machine.

* | Support selinux options with bind mounts play/genBrent Baude2021-09-30
|/ | | | | | | | | | | | When using play kube and generate kube, we need to support if bind mounts have selinux options. As kubernetes does not support selinux in this way, we tuck the selinux values into a pod annotation for generation of the kube yaml. Then on play, we check annotations to see if a value for the mount exists and apply it. Fixes BZ #1984081 Signed-off-by: Brent Baude <bbaude@redhat.com>
* Add init containers to generate and play kubeUrvashi Mohnani2021-09-10
| | | | | | | | | | | | | | | Kubernetes has a concept of init containers that run and exit before the regular containers in a pod are started. We added init containers to podman pods as well. This patch adds support for generating init containers in the kube yaml when a pod we are converting had init containers. When playing a kube yaml, it detects an init container and creates such a container in podman accordingly. Note, only init containers created with the init type set to "always" will be generated as the "once" option deletes the init container after it has run and exited. Play kube will always creates init containers with the "always" init container type. Signed-off-by: Urvashi Mohnani <umohnani@redhat.com>
* InfraContainer Reworkcdoern2021-08-26
| | | | | | | | | | InfraContainer should go through the same creation process as regular containers. This change was from the cmd level down, involving new container CLI opts and specgen creating functions. What now happens is that both container and pod cli options are populated in cmd and used to create a podSpecgen and a containerSpecgen. The process then goes as follows FillOutSpecGen (infra) -> MapSpec (podOpts -> infraOpts) -> PodCreate -> MakePod -> createPodOptions -> NewPod -> CompleteSpec (infra) -> MakeContainer -> NewContainer -> newContainer -> AddInfra (to pod state) Signed-off-by: cdoern <cdoern@redhat.com>
* Network interfacePaul Holzinger2021-08-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement a new network interface to abstract CNI from libpod. The interface is implemented for the CNI backend but in the future we can add more backends. The code is structured in three new packages: - `libpod/network/types`: contains the interface definition and the necessary types for it. - `libpod/network/cni` contains the interface implementation for the CNI backend. - `libpod/network/util` a set of utility functions related to networking. The CNI package uses ginkgo style unit tests. To test Setup/Teardown the test must be run as root. Each test will run in their own namespace to make the test independent from the host environment. New features with the CNI backend: - The default network will be created in memory if it does not exists on disk. - It can set more than one static IP per container network. - Networks are loaded once from disk and only if this interface is used, e.g. for commands such as `podman info` networks are not loaded. This reduces unnecessary disk IO. This commit only adds the interface it is not wired into libpod. This requires a lot of breaking changes which will be done in a followup commit. Once this is integrated into libpod the current network code under `libpod/network` should be removed. Also the dependency on OCICNI should be dropped.

* migrate Podman to containers/common/libimageValentin Rothberg2021-05-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Migrate the Podman code base over to `common/libimage` which replaces `libpod/image` and a lot of glue code entirely. Note that I tried to leave bread crumbs for changed tests. Miscellaneous changes: * Some errors yield different messages which required to alter some tests. * I fixed some pre-existing issues in the code. Others were marked as `//TODO`s to prevent the PR from exploding. * The `NamesHistory` of an image is returned as is from the storage. Previously, we did some filtering which I think is undesirable. Instead we should return the data as stored in the storage. * Touched handlers use the ABI interfaces where possible. * Local image resolution: previously Podman would match "foo" on "myfoo". This behaviour has been changed and Podman will now only match on repository boundaries such that "foo" would match "my/foo" but not "myfoo". I consider the old behaviour to be a bug, at the very least an exotic corner case. * Futhermore, "foo:none" does *not* resolve to a local image "foo" without tag anymore. It's a hill I am (almost) willing to die on. * `image prune` prints the IDs of pruned images. Previously, in some cases, the names were printed instead. The API clearly states ID, so we should stick to it. * Compat endpoint image removal with _force_ deletes the entire not only the specified tag. Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | In K8S the pod creation fails if an env var reference a non existing config map key. It can be marked as optional, but per default it is mandatory.
