* generate kube: handle entrypointValentin Rothberg2021-02-04
| | | | | | | | | | The spec of a Kube Container has a `Command` and `Args`. While both are slices, the `Command` is the counterpart of the entrypoint of a libpod container. Kube is also happily accepting the arguments to as following items in the slice but it's cleaner to move those to `Args`. Fixes: #9211 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
* Allow pods to use --net=noneMatthew Heon2021-02-04
| | | | | | | | | | | We need an extra field in the pod infra container config. We may want to reevaluate that struct at some point, as storing network modes as bools will rapidly become unsustainable, but that's a discussion for another time. Otherwise, straightforward plumbing. Fixes #9165 Signed-off-by: Matthew Heon <matthew.heon@pm.me>

* Fix --network parsing for podman pod createPaul Holzinger2021-02-04
| | | | | | | | | | | | The `--network` flag is parsed differently for `podman pod create`. This causes confusion and problems for users. The extra parsing logic ignored unsupported network options such as `none`, `container:...` and `ns:...` and instead interpreted them as cni network names. Tests are added to ensure the correct errors are shown. Signed-off-by: Paul Holzinger <paul.holzinger@web.de>
* Docker ignores mount flags that begin with constencyDaniel J Walsh2021-02-04
| | | | | | | | | | | | | | Fixes https://bugzilla.redhat.com/show_bug.cgi?id=1915332 ``` According to the Docker docs, the consistency option should be ignored on Linux. the possible values are 'cached', 'delegated', and 'consistent', but they should be ignored equally. This is a widely used option in scripts run by developer machines, as this makes file I/O less horribly slow on MacOS. ``` Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>

* Honor custom DNS in play|generate kubebaude2021-02-04
| | | | | | | | | | | | | | | | | | when creating kubernetes yaml from containers and pods, we should honor any custom dns settings the user provided. in the case of generate kube, these would be provided by --dns, --dns-search, and --dns-opt. if multiple containers are involved in the generate, the options will be cumulative and unique with the exception of dns-opt. when replaying a kube file that has kubernetes dns information, we now also add that information to the pod creation. the options for dnspolicy is not enabled as there seemed to be no direct correlation between kubernetes and podman. Fixes: #9132 Signed-off-by: baude <bbaude@redhat.com>
* add macvlan as a supported network driverbaude2021-02-02
| | | | | | | | | | | | instead of using the --macvlan to indicate that you want to make a macvlan network, podman network create now honors the driver name of *macvlan*. Any options to macvlan, like the parent device, should be specified as a -o option. For example, -o parent=eth0. the --macvlan option was marked as deprecated in the man page but is still supported for the duration of 3.0. Signed-off-by: baude <bbaude@redhat.com>
* Make generate systemd --new robust against double curly bracesPaul Holzinger2021-01-29
| | | | | | | | | | | If the container create command contains an argument with double curly braces the golang template parsing can fail since it tries to interpret the value as variable. To fix this change the default delimiter for the internal template to `{{{{`. Fixes #9034 Signed-off-by: Paul Holzinger <paul.holzinger@web.de>
* workdir presence checksValentin Rothberg2021-01-29
| | | | | | | | | | | | | | | | | | A container's workdir can be specified via the CLI via `--workdir` and via an image config with the CLI having precedence. Since images have a tendency to specify workdirs without necessarily shipping the paths with the root FS, make sure that Podman creates the workdir. When specified via the CLI, do not create the path, but check for its existence and return a human-friendly error. NOTE: `crun` is performing a similar check that would yield exit code 127. With this change, however, Podman performs the check and yields exit code 126. Since this is specific to `crun`, I do not consider it to be a breaking change of Podman.

| * Allow podman push to push manifest listsDaniel J Walsh2021-01-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When doing a podman images, manifests lists look just like images, so it is logical that users would assume that they can just podman push them to a registry. The problem is we throw out weird errors when this happens and users need to somehow figure out this is a manifest list rather then an image, and frankly the user will not understand the difference. This PR will make podman push just do the right thing, by failing over and attempting to push the manifest if it fails to push the image. Fix up handling of manifest push Protocol should bring back a digest string, which can either be printed or stored in a file. We should not reimplement the manifest push setup code in the tunnel code but take advantage of the api path, to make sure remote and local work the same way.

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.

* | | Add tests for volume pluginsMatthew Heon2021-01-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | This involves a new test binary (a basic implementation of the volume plugin protocol) and a new image on quay.io (Containerfile to produce it and all sources located in this commit).

Support for actually retrieving plugins requires a pull request to land in containers.conf and then that to be vendored, and as such is not yet ready. Given this, this code is only compile tested. However, the code for everything past retrieving the plugin has been written - there is support for creating, removing, mounting, and unmounting volumes, which should allow full functionality once the c/common PR is merged. A major change is the signature of the MountPoint function for volumes, which now, by necessity, returns an error. Named volumes managed by a plugin do not have a mountpoint we control; instead, it is managed entirely by the plugin. As such, we need to cache the path in the DB, and calls to retrieve it now need to access the DB (and may fail as such). Notably absent is support for SELinux relabelling and chowning these volumes. Given that we don't manage the mountpoint for these volumes, I am extremely reluctant to try and modify it - we could easily break the plugin trying to chown or relabel it. Also, we had no less than *5* separate implementations of inspecting a volume floating around in pkg/infra/abi and pkg/api/handlers/libpod. And none of them used volume.Inspect(), the only correct way of inspecting volumes. Remove them all and consolidate to using the correct way. Compat API is likely still doing things the wrong way, but that is an issue for another day. Fixes #4304 Signed-off-by: Matthew Heon <matthew.heon@pm.me>
