* add {generate,play} kubeValentin Rothberg2020-05-06
| | | | | | | | | | | | | | | | | | | Add the `podman generate kube` and `podman play kube` command. The code has largely been copied from Podman v1 but restructured to not leak the K8s core API into the (remote) client. Both commands are added in the same commit to allow for enabling the tests at the same time. Move some exports from `cmd/podman/common` to the appropriate places in the backend to avoid circular dependencies. Move definitions of label annotations to `libpod/define` and set the security-opt labels in the frontend to make kube tests pass. Implement rest endpoints, bindings and the tunnel interface.

* auto updatesValentin Rothberg2020-03-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support to auto-update containers running in systemd units as generated with `podman generate systemd --new`. `podman auto-update` looks up containers with a specified "io.containers.autoupdate" label (i.e., the auto-update policy). If the label is present and set to "image", Podman reaches out to the corresponding registry to check if the image has been updated. We consider an image to be updated if the digest in the local storage is different than the one of the remote image. If an image must be updated, Podman pulls it down and restarts the container. Note that the restarting sequence relies on systemd. At container-creation time, Podman looks up the "PODMAN_SYSTEMD_UNIT" environment variables and stores it verbatim in the container's label. This variable is now set by all systemd units generated by `podman-generate-systemd` and is set to `%n` (i.e., the name of systemd unit starting the container). This data is then being used in the auto-update sequence to instruct systemd (via DBUS) to restart the unit and hence to restart the container. Note that this implementation of auto-updates relies on systemd and requires a fully-qualified image reference to be used to create the container. This enforcement is necessary to know which image to actually check and pull. If we used an image ID, we would not know which image to check/pull anymore.

| * | Allow devs to set labels in container images for default capabilities.Daniel J Walsh2020-03-02
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch allows users to specify the list of capabilities required to run their container image. Setting a image/container label "io.containers.capabilities=setuid,setgid" tells podman that the contained image should work fine with just these two capabilties, instead of running with the default capabilities, podman will launch the container with just these capabilties. If the user or image specified capabilities that are not in the default set, the container will print an error message and will continue to run with the default capabilities.

* Remove ImageVolumes from databaseMatthew Heon2020-02-21
| | | | | | | | | | | | | | Before Libpod supported named volumes, we approximated image volumes by bind-mounting in per-container temporary directories. This was handled by Libpod, and had a corresponding database entry to enable/disable it. However, when we enabled named volumes, we completely rewrote the old implementation; none of the old bind mount implementation still exists, save one flag in the database. With nothing remaining to use it, it has no further purpose. Signed-off-by: Matthew Heon <mheon@redhat.com>

| * Use cleaned destination path for indexing image volumesMatthew Heon2020-02-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | We use filepath.Clean() to remove trailing slashes to ensure that when we supercede image mounts with mounts from --volume and --mount, paths are consistent when we compare. Unfortunately, while we used the cleaned path for the destination in the mount, it was accidentally not used to index the maps that we use to identify what to supercede, so our comparisons might be thrown off by trailing slashes and similar.

In addition to the default behaviour (default profile unless --security-opt seccomp is set) add a second policy doing a lookup in the image annotation. If the image has the "io.containers.seccomp.profile" set its value will be interpreted as a seccomp profile. The policy can be selected via the new --seccomp-policy CLI flag. Once the containers.conf support is merged into libpod, we can add an option there as well. Note that this feature is marked as experimental and may change in the future.

* Split up create config handling of namespaces and securityPeter Hunt2019-11-07
| | | | | | | | As it stands, createconfig is a huge struct. This works fine when the only caller is when we create a container with a fully created config. However, if we wish to share code for security and namespace configuration, a single large struct becomes unweildy, as well as difficult to configure with the single createConfigToOCISpec function. This PR breaks up namespace and security configuration into their own structs, with the eventual goal of allowing the namespace/security fields to be configured by the pod create cli, and allow the infra container to share this with the pod's containers.

* | Add support for anonymous volumes to `podman run -v`Matthew Heon2019-10-17
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, when `podman run` encountered a volume mount without separate source and destination (e.g. `-v /run`) we would assume that both were the same - a bind mount of `/run` on the host to `/run` in the container. However, this does not match Docker's behavior - in Docker, this makes an anonymous named volume that will be mounted at `/run`. We already have (more limited) support for these anonymous volumes in the form of image volumes. Extend this support to allow it to be used with user-created volumes coming in from the `-v` flag. This change also affects how named volumes created by the container but given names are treated by `podman run --rm` and `podman rm -v`. Previously, they would be removed with the container in these cases, but this did not match Docker's behaviour. Docker only removed anonymous volumes. With this patch we move to that model as well; `podman run -v testvol:/test` will not have `testvol` survive the container being removed by `podman rm -v`. The sum total of these changes let us turn on volume removal in `--rm` by default. Fixes: #4276 Signed-off-by: Matthew Heon <matthew.heon@pm.me>
