pod: fix duplicate volumes from containers.conf
If some volumes are specified in containers.conf, they are currently
added twice to the containers spec causing the container to fail:

$ head -n2 ~/.config/containers/containers.conf
[containers]
volumes = ["/tmp:/tmp"]
$ podman pod create --name foo
7ac7f97f9b74a596332483e4a13e58cb9c8d997e9c5baae46804ae0acc26cbc6
$ podman run --pod=foo alpine true
Error: "/tmp": duplicate mount destination

The fix is to ignore the setting from containers.conf when setting the
pod default configuration.

Matthew Heon 398e48a24a Change Inherit to use a pointer to a container
This fixes a lint issue, but I'm keeping it in its own commit so
it can be reverted independently if necessary; I don't know what
side effects this may have. I don't *think* there are any

This probably should have been in the API since the beginning,
but it's not too late to start now.

The extra information is returned (both via the REST API, and to
the CLI handler for `podman rm`) but is not yet printed - it
feels like adding it to the output could be a breaking change?

Urvashi Mohnani edbeee5238 Add --restart flag to pod create
Add --restart flag to pod create to allow users to set the
restart policy for the pod, which applies to all the containers
in the pod. This reuses the restart policy already there for
containers and has the same restart policy options.
Add "never" to the restart policy options to match k8s syntax.
It is a synonym for "no" and does the exact same thing where the
containers are not restarted once exited.
Only the containers that have exited will be restarted based on the
restart policy, running containers will not be restarted when an exited
container is restarted in the same pod (same as is done in k8s).

Stefano Brivio aa47e05ae4 libpod: Add pasta networking mode
Conceptually equivalent to networking by means of slirp4netns(1),
with a few practical differences:

- pasta(1) forks to background once networking is configured in the
  namespace and quits on its own once the namespace is deleted:
  file descriptor synchronisation and PID tracking are not needed

- port forwarding is configured via command line options at start-up,
  instead of an API socket: this is taken care of right away as we're
  about to start pasta

- there's no need for further selection of port forwarding modes:
  pasta behaves similarly to containers-rootlessport for local binds
  (splice() instead of read()/write() pairs, without L2-L4
  translation), and keeps the original source address for non-local
  connections like slirp4netns does

- IPv6 is not an experimental feature, and enabled by default. IPv6
  port forwarding is supported

- by default, addresses and routes are copied from the host, that is,
  container users will see the same IP address and routes as if they
  were in the init namespace context. The interface name is also
  sourced from the host upstream interface with the first default
  route in the routing table. This is also configurable as documented

- sandboxing and seccomp(2) policies cannot be disabled

- only rootless mode is supported.

See https://passt.top for more details about pasta.

Also add a link to the maintained build of pasta(1) manual as valid
in the man page cross-reference checks: that's where the man page
for the latest build actually is -- it's not on Github and it doesn't
match any existing pattern, so add it explicitly.

fix podman pod inspect to support multiple pods
Just like the other inspect commands `podman pod inspect p1 p2` should
return the json for both.

To correctly implement this we follow the container inspect logic, this
allows use to reuse the global inspect command.
Note: To not break the existing single pod output format for podman pod
inspect I added a pod-legacy inspect type. This is only used to make
sure we will print the pod as single json and not an array like for the
other commands. We cannot use the pod type since podman inspect --type
pod did return an array and we should not break that as well.

Valentin Rothberg 4eff0c8cf2 pod: add exit policies
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".

shell completion --format: work with nil structs
AutocompleteFormat() takes the format struct as argument. Often the structs
are deeply nested and contain other structs. Up until now if there was a
pointer to a struct the logic was not able to get the field names from
that, simply because the pointer was nil. However it is possible to
create a new initialized type with reflect.New(). This allows us to
complete all struct fields/functions even when there nil pointers.
Therefore we can drop the extra initialization which was done by some
callers.

enable gocritic linter

- 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.
