We can infer no-new-privileges. For now, manually populate
seccomp (can't infer what file we sourced from) and
SELinux/Apparmor (hard to tell if they're enabled or not).

When we first began writing Podman, we ran into a major issue
when implementing Inspect. Libpod deliberately does not tie its
internal data structures to Docker, and stores most information
about containers encoded within the OCI spec. However, Podman
must present a CLI compatible with Docker, which means it must
expose all the information in 'docker inspect' - most of which is
not contained in the OCI spec or libpod's Config struct.
Our solution at the time was the create artifact. We JSON'd the
complete CreateConfig (a parsed form of the CLI arguments to
'podman run') and stored it with the container, restoring it when
we needed to run commands that required the extra info.
Over the past month, I've been looking more at Inspect, and
refactored large portions of it into Libpod - generating them
from what we know about the OCI config and libpod's (now much
expanded, versus previously) container configuration. This path
comes close to completing the process, moving the last part of
inspect into libpod and removing the need for the create
artifact.
This improves libpod's compatability with non-Podman containers.
We no longer require an arbitrarily-formatted JSON blob to be
present to run inspect.
Fixes: #3500

In Go templating, we use the names of fields, not the JSON struct
tags. To ensure templating works are expected, we need the two to

Go templating is incapable of dealing with pointers, so when we
moved to Docker compatible mounts JSON, we broke it. The solution
is to not use pointers in this part of inspect.

Swap to using the on-disk spec for inspect mounts
|
| |
| |
| |
| |
| |
| |
| |
| |
| |
| | |
When available, using the on-disk spec will show full mount
options in use when the container is running, which can differ
from mount options provided in the original spec - on generating
the final spec, for example, we ensure that some form of root
propagation is set.

We were formerly dumping spec.Mount structs, with no care as to
whether it was user-generated or not - a relic of the very early
days when we didn't know whether a user made a mount or not.
Now that we do, match our output to Docker's dedicated mount
struct.

Let's put inspect structs where they're actually being used. We
originally made pkg/inspect to solve circular import issues.
There are no more circular import issues.
Image structs remain for now, I'm focusing on container inspect.

The on-failure restart option supports restarting only a given
number of times. To do this, we need one additional field in the
DB to track restart count (which conveniently fills a field in
Inspect we weren't populating), plus some plumbing logic.

integration of healthcheck into create and run as well as inspect.
healthcheck enhancements are as follows:
* add the following options to create|run so that non-docker images can
define healthchecks at the container level.
* --healthcheck-command
* --healthcheck-retries
* --healthcheck-interval
* --healthcheck-start-period
* podman create|run --healthcheck-command=none disables healthcheck as
described by an image.
* the healthcheck itself and the healthcheck "history" can now be
observed in podman inspect
* added the wiring for healthcheck history which logs the health history
of the container, the current failed streak attempts, and log entries
for the last five attempts which themselves have start and stop times,
result, and a 500 character truncated (if needed) log of stderr/stdout.
The timings themselves are not implemented in this PR but will be in
future enablement (i.e. next).

Apply the default AppArmor profile at container initialization to cover
all possible code paths (i.e., podman-{start,run}) before executing the
runtime. This allows moving most of the logic into pkg/apparmor.
Also make the loading and application of the default AppArmor profile
versio-indepenent by checking for the `libpod-default-` prefix and
over-writing the profile in the run-time spec if needed.
The intitial run-time spec of the container differs a bit from the
applied one when having started the container, which results in
displaying a potentially outdated AppArmor profile when inspecting
a container. To fix that, load the container config from the file
system if present and use it to display the data.

Add support for podman volume and its subcommands.
The commands supported are:
podman volume create
podman volume inspect
podman volume ls
podman volume rm
podman volume prune
This is a tool to manage volumes used by podman. For now it only handle
named volumes, but eventually it will handle all volumes used by podman.

this should represent the last major changes to get darwin to **compile**. again,
the purpose here is to get darwin to compile so that we can eventually implement a
ci task that would protect against regressions for darwin compilation.
i have left the manual darwin compilation largely static still and in fact now only
interject (manually) two build tags to assist with the build. trevor king has great
ideas on how to make this better and i will defer final implementation of those
to him.

Refactors creation of bind mounts into a separate function that
can be called from elsewhere (e.g. pod start or container
restart). This function stores the mounts in the DB using the
field established last commit.
Spec generation now relies upon this field in the DB instead of
manually enumerating files to be bind mounted in.
