Fix --arch and --os flags to work correctly
Currently podman implements --override-arch and --overide-os
But Podman has made these aliases for --arch and --os.  No
reason to have to specify --override, since it is clear what
the user intends.

Currently if the user specifies an --override-arch field but the
image was previously pulled for a different Arch, podman run uses
the different arch.  This PR also fixes this issue.

Fix handling of container remove
I found several problems with container remove

podman-remote rm --all
Was not handled

podman-remote rm --ignore
Was not handled

Return better errors when attempting to remove an --external container.
Currently we return the container does not exists, as opposed to container
is an external container that is being used.

This patch also consolidates the tunnel code to use the same code for
removing the container, as the local API, removing duplication of code
and potential problems.

Allow podman push to push manifest lists

Daniel J Walsh cf51c7ed9f
Allow podman push to push manifest lists
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.

Container Rename
2021-01-14 22:03:01 -05:00
Matthew Heon 997de2f8e9 Initial implementation of renaming containers
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.

Matthew Heon b53cb57680 Initial implementation of volume plugins
This implements support for mounting and unmounting volumes
backed by volume plugins. 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.

Matthew Heon 7e3fb33be8 Ensure that `podman play kube` actually reports errors
In 2.2.x, we moved `play kube` to use the Start() API for pods,
which reported errors in a different way (all containers are
started in parallel, and then results reported as a block). The
migration attempted to preserve compatibility by returning only
one error, but that's not really a viable option as it can
obscure the real reason that a pod is failing. Further, the code
was not correctly handling the API's errors - Pod Start() will,
on any container error, return a map of container ID to error
populated for all container errors *and* return ErrPodPartialFail
for overall error - the existing code did not handle the partial
failure error and thus would never return container errors.

Refactor the `play kube` API to include a set of errors for
containers in each pod, so we can return all errors that occurred
to the frontend and print them for the user, and correct the
backend code so container errors are actually forwarded.

Radostin Stoyanov 288ccc4c84 Include named volumes in container migration
When migrating a container with associated volumes, the content of
these volumes should be made available on the destination machine.

This patch enables container checkpoint/restore with named volumes
by including the content of volumes in checkpoint file. On restore,
volumes associated with container are created and their content is
restored.

The --ignore-volumes option is introduced to disable this feature.

Example:

 # podman container checkpoint --export checkpoint.tar.gz <container>

The content of all volumes associated with the container are included
in `checkpoint.tar.gz`

 # podman container checkpoint --export checkpoint.tar.gz --ignore-volumes <container>

The content of volumes is not included in `checkpoint.tar.gz`. This is
useful, for example, when the checkpoint/restore is performed on the
same machine.

 # podman container restore --import checkpoint.tar.gz

The associated volumes will be created and their content will be
restored. Podman will exit with an error if volumes with the same
name already exist on the system or the content of volumes is not
included in checkpoint.tar.gz

 # podman container restore --ignore-volumes --import checkpoint.tar.gz

Volumes associated with container must already exist. Podman will not
create them or restore their content.
