Add ability to evict a container
|

| |
| |
| |

| |
| |
| |
| | |
Add ability to evict a container when it becomes unusable. This may
happen when the host setup changes after a container creation, making it
impossible for that container to be used or removed.
Evicting a container is done using the `rm --force` command.

when running a container remotely, we should only be sending stdin when
running with --interactive; otherwise use nil.

This change matches what is happening on the podman local side
and should eliminate a race condition.
Also exit commands on the server side should start to return to client.

Drop the support for remote clients to generate systemd-service files.
The generated files are machine-dependent and hence relate only to the
a local machine. Furthermore, a proper service management when using
a remote-client is not possible as systemd has no access to a process.
Dropping the support will also reduce the risk of making users believe
that the generated services are usable in a remote scenario.

There's no way to get the error if we successfully get an exit code (as it's just printed to stderr instead).
instead of relying on the error to be passed to podman, and edit based on the error code, process it on the varlink side instead
Also move error codes to define package

Include changes to the container's root file-system in the checkpoint archive

The newly added functionality to include the container's root
file-system changes into the checkpoint archive can now be explicitly
disabled. Either during checkpoint or during restore.
If a container changes a lot of files during its runtime it might be
more effective to migrated the root file-system changes in some other
way and to not needlessly increase the size of the checkpoint archive.
If a checkpoint archive does not contain the root file-system changes
information it will automatically be skipped. If the root file-system
changes are part of the checkpoint archive it is also possible to tell
Podman to ignore these changes.

the compilation demands of having libpod in main is a burden for the
remote client compilations. to combat this, we should move the use of
libpod structs, vars, constants, and functions into the adapter code
where it will only be compiled by the local client.
this should result in cleaner code organization and smaller binaries. it
should also help if we ever need to compile the remote client on
non-Linux operating systems natively (not cross-compiled).

Let's put inspect structs where they're actually being used. We

There are no more circular import issues.
Image structs remain for now, I'm focusing on container inspect.

This commit adds an option to the checkpoint command to export a
checkpoint into a tar.gz file as well as importing a checkpoint tar.gz
file during restore. With all checkpoint artifacts in one file it is
possible to easily transfer a checkpoint and thus enabling container
migration in Podman. With the following steps it is possible to migrate
a running container from one system (source) to another (destination).
Source system:
* podman container checkpoint -l -e /tmp/checkpoint.tar.gz
* scp /tmp/checkpoint.tar.gz destination:/tmp
Destination system:
* podman pull 'container-image-as-on-source-system'
* podman container restore -i /tmp/checkpoint.tar.gz
The exported tar.gz file contains the checkpoint image as created by
CRIU and a few additional JSON files describing the state of the
checkpointed container.
Now the container is running on the destination system with the same
state just as during checkpointing. If the container is kept running
on the source system with the checkpoint flag '-R', the result will be
that the same container is running on two different hosts.

when doing any sort of attach to a container, a sigwinch is sent
followed by a resize event. this is fine for the local client but when
doing things over the varlink, the first sigwinch is wiped out by the
immediate resize event and is therefore lost. by making the channel
buffered, both events are processed after the varlink connection is
established.

the podman generate systemd command will generate a systemd unit file
based on the attributes of an existing container and user inputs. the
command outputs the unit file to stdout for the user to copy or
redirect. it is enabled for the remote client as well.
users can set a restart policy as well as define a stop timeout
override for the container.

As part of this, rework the number of workers used by various
Podman tasks to match original behavior - need an explicit
fallthrough in the switch statement for that block to work as
expected.
Also, trivial change to Podman cleanup to work on initialized
containers - we need to reset to a different state after cleaning
up the OCI runtime.

Also, you can now podman-remote run -it. There are some bugs that need
to be ironed out but I would prefer to merge this so we can make both
progress on start and exec as well as the bugs.
* when doing podman-remote run -it foo /bin/bash, you have to press
enter to get the prompt to display. with the localized podman, we had to
teach it connect to the console first and then start the container so we
did not miss anything.
* when executing "exit" in the console, we get a hard lockup likely
because nobody knows what to do.
* custom detach keys are not supported
* podman-remote run -it alpine ls does not currently work. only
dropping to a shell works.
