Truncate annotations when generating kubernetes yaml files
Kubernetes only allows 63 characters in an annotation.  Make sure
that we only add 63 or less charaters when generating kube. Warn
if containers or pods have longer length and truncate.

enable gocritic linter
The linter ensures a common code style.
- 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.
This should help maintainability.

It seems this breaks older version of `podman-remote` users hence it
looks like this patch would be a better candidate for podman `5.0`

Add support for checkpoint image
This is an enhancement proposal for the checkpoint / restore feature of
Podman that enables container migration across multiple systems with
standard image distribution infrastructure.

A new option `--create-image <image>` has been added to the
`podman container checkpoint` command. This option tells Podman to
create a container image.  This is a standard image with a single layer,
tar archive, that that contains all checkpoint files. This is similar to
the current approach with checkpoint `--export`/`--import`.

This image can be pushed to a container registry and pulled on a
different system.  It can also be exported locally with `podman image
save` and inspected with `podman inspect`. Inspecting the image would
display additional information about the host and the versions of
Podman, criu, crun/runc, kernel, etc.

`podman container restore` has also been extended to support image
name or ID as input.

Matthew Heon 141de86862 Revamp Libpod state strings for Docker compat
Improve our compatibility with Docker by better handling the
state strings that we print in `podman ps`. Docker capitalizes
all states in `ps` (we do not) - fix this in our PS code. Also,
stop normalizing ContainerStateConfigured to the "Created" state,
and instead make it always be Created, with the existing Created
state becoming Initialized.

I didn't rename the actual states because I'm somewhat reticent
to make such a large change a day before we leave for break. It's
somewhat confusing that ContainerStateConfigured now returns
Created, but internally and externally we're still consistent.

[NO NEW TESTS NEEDED] existing tests should catch anything that
broke.

I also consider this a breaking change. I will flag appropriately
on Github.

Set volume NeedsCopyUp to false iff data was copied up
2022-01-07 20:38:59 +01:00
Brent Baude 2a524fcaec fix healthcheck timeouts and ut8 coercion
this commit fixes two bugs and adds regression tests.

when getting healthcheck values from an image, if the image does not
have a timeout defined, this resulted in a 0 value for timeout.  The
default as described in the man pages is 30s.

when inspecting a container with a healthcheck command, a customer
observed that the &, <, and > characters were being converted into a
unicode escape value.  It turns out json marshalling will by default
coerce string values to ut8.

cdoern 289270375a Pod Security Option support
Added support for pod security options. These are applied to infra and passed down to the
containers as added (unless overridden).

Modified the inheritance process from infra, creating a new function Inherit() which reads the config, and marshals the compatible options into an intermediate struct `InfraInherit`
This is then unmarshaled into a container config and all of this is added to the CtrCreateOptions. Removes the need (mostly) for special additons which complicate the Container_create
code and pod creation.

Do not store the exit command in container config
There is a problem with creating and storing the exit command when the
container was created. It only contains the options the container was
created with but NOT the options the container is started with. One
example would be a CNI network config. If I start a container once, then
change the cni config dir with `--cni-config-dir` ans start it a second
time it will start successfully. However the exit command still contains
the wrong `--cni-config-dir` because it was not updated.

To fix this we do not want to store the exit command at all. Instead we
create it every time the conmon process for the container is startet.
This guarantees us that the container cleanup process is startet with
the correct settings.

Added optional container checkpointing statistics
This adds the parameter '--print-stats' to 'podman container checkpoint'.
With '--print-stats' Podman will measure how long Podman itself, the OCI
runtime and CRIU requires to create a checkpoint and print out these
information. CRIU already creates checkpointing statistics which are
just read in addition to the added measurements. In contrast to just
printing out the ID of the checkpointed container, Podman will now print
out JSON:

 # podman container checkpoint --latest --print-stats
 {
     "podman_checkpoint_duration": 360749,
     "container_statistics": [
         {
             "Id": "25244244bf2efbef30fb6857ddea8cb2e5489f07eb6659e20dda117f0c466808",
             "runtime_checkpoint_duration": 177222,
             "criu_statistics": {
                 "freezing_time": 100657,
                 "frozen_time": 60700,
                 "memdump_time": 8162,
                 "memwrite_time": 4224,
                 "pages_scanned": 20561,
                 "pages_written": 2129
             }
         }
     ]
 }

The output contains 'podman_checkpoint_duration' which contains the
number of microseconds Podman required to create the checkpoint. The
output also includes 'runtime_checkpoint_duration' which is the time
the runtime needed to checkpoint that specific container. Each container
also includes 'criu_statistics' which displays the timing information
collected by CRIU.

Valentin Rothberg 0f7d54b026 migrate Podman to containers/common/libimage
Migrate the Podman code base over to `common/libimage` which replaces
`libpod/image` and a lot of glue code entirely.

Note that I tried to leave bread crumbs for changed tests.

Miscellaneous changes:

 * Some errors yield different messages which required to alter some
   tests.

 * I fixed some pre-existing issues in the code.  Others were marked as
   `//TODO`s to prevent the PR from exploding.

 * The `NamesHistory` of an image is returned as is from the storage.
   Previously, we did some filtering which I think is undesirable.
   Instead we should return the data as stored in the storage.

 * Touched handlers use the ABI interfaces where possible.

 * Local image resolution: previously Podman would match "foo" on
   "myfoo".  This behaviour has been changed and Podman will now
   only match on repository boundaries such that "foo" would match
   "my/foo" but not "myfoo".  I consider the old behaviour to be a
   bug, at the very least an exotic corner case.

 * Futhermore, "foo:none" does *not* resolve to a local image "foo"
   without tag anymore.  It's a hill I am (almost) willing to die on.

 * `image prune` prints the IDs of pruned images.  Previously, in some
   cases, the names were printed instead.  The API clearly states ID,
   so we should stick to it.

 * Compat endpoint image removal with _force_ deletes the entire not
   only the specified tag.

Matthew Heon 6acd265306 Add --requires flag to podman run/create
Podman has, for a long time, had an internal concept of
dependency management, used mainly to ensure that pod infra
containers are started before any other container in the pod. We
also have the ability to recursively start these dependencies,
which we use to ensure that `podman start` on a container in a
pod will not fail because the infra container is stopped. We have
not, however, exposed these via the command line until now.

Add a `--requires` flag to `podman run` and `podman create` to
allow users to manually specify dependency containers. These
containers must be running before the container will start. Also,
make recursive starting with `podman start` default so we can
start these containers and their dependencies easily.

Some packages used by the remote client imported the libpod package.
This is not wanted because it adds unnecessary bloat to the client and
also causes problems with platform specific code(linux only), see #9710.

The solution is to move the used functions/variables into extra packages
which do not import libpod.

This change shrinks the remote client size more than 6MB compared to the

podman cp: support copying on tmpfs mounts
2021-03-05 03:57:17 -05:00
Valentin Rothberg a090301bbb podman cp: support copying on tmpfs mounts
Traditionally, the path resolution for containers has been resolved on
the *host*; relative to the container's mount point or relative to
specified bind mounts or volumes.

While this works nicely for non-running containers, it poses a problem
for running ones.  In that case, certain kinds of mounts (e.g., tmpfs)
will not resolve correctly.  A tmpfs is held in memory and hence cannot
be resolved relatively to the container's mount point.  A copy operation
will succeed but the data will not show up inside the container.

To support these kinds of mounts, we need to join the *running*
container's mount namespace (and PID namespace) when copying.

Note that this change implies moving the copy and stat logic into
`libpod` since we need to keep the container locked to avoid race
conditions.  The immediate benefit is that all logic is now inside
`libpod`; the code isn't scattered anymore.

Further note that Docker does not support copying to tmpfs mounts.

Tests have been extended to cover *both* path resolutions for running
and created containers.  New tests have been added to exercise the
tmpfs-mount case.

For the record: Some tests could be improved by using `start -a` instead
of a start-exec sequence.  Unfortunately, `start -a` is flaky in the CI
which forced me to use the more expensive start-exec option.

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.

Valentin Rothberg d54478d8ea container stop: release lock before calling the runtime
Podman defers stopping the container to the runtime, which can take some
time.  Keeping the lock while waiting for the runtime to complete the
stop procedure, prevents other commands from acquiring the lock as shown
in #8501.

To improve the user experience, release the lock before invoking the
runtime, and re-acquire the lock when the runtime is finished.  Also
introduce an intermediate "stopping" to properly distinguish from
"stopped" containers etc.

Juan Antonio Osorio Robles 020abbfeab Expose security attribute errors with their own messages
This creates error objects for runtime errors that might come from the
runtime. Thus, indicating to users that the place to debug should be in
the security attributes of the container.

When creating a container with a SELinux label that doesn't exist, we
get a fairly cryptic error message:

```
$ podman run --security-opt label=type:my_container.process -it fedora bash
Error: OCI runtime error: write file `/proc/thread-self/attr/exec`: Invalid argument
```

This instead handles any errors coming from LSM's `/proc` API and
enhances the error message with a relevant indicator that it's related
to the container's security attributes.

A sample run looks as follows:

```
$ bin/podman run --security-opt label=type:my_container.process -it fedora bash
Error: `/proc/thread-self/attr/exec`: OCI runtime error: unable to assign security attribute
```

With `debug` log level enabled it would be:

```
Error: write file `/proc/thread-self/attr/exec`: Invalid argument: OCI runtime error: unable to assign security attribute
```

Note that these errors wrap ErrOCIRuntime, so it's still possible to to
compare these errors with `errors.Is/errors.As`.

One advantage of this approach is that we could start handling these
errors in a more efficient manner in the future.

e.g. If a SELinux label doesn't exist (yet), we could retry until it
becomes available.

Matthew Heon 8d56eb5342 Add support for network connect / disconnect to DB
Convert the existing network aliases set/remove code to network
connect and disconnect. We can no longer modify aliases for an
existing network, but we can add and remove entire networks. As
part of this, we need to add a new function to retrieve current
aliases the container is connected to (we had a table for this
as of the first aliases PR, but it was not externally exposed).

At the same time, remove all deconflicting logic for aliases.
Docker does absolutely no checks of this nature, and allows two
containers to have the same aliases, aliases that conflict with
container names, etc - it's just left to DNS to return all the
IP addresses, and presumably we round-robin from there? Most
tests for the existing code had to be removed because of this.

Convert all uses of the old container config.Networks field,
which previously included all networks in the container, to use
the new DB table. This ensures we actually get an up-to-date list
of in-use networks. Also, add network aliases to the output of
`podman inspect`.

This adds the database backend for network aliases. Aliases are
additional names for a container that are used with the CNI
dnsname plugin - the container will be accessible by these names
in addition to its name. Aliases are allowed to change over time
as the container connects to and disconnects from networks.

Aliases are implemented as another bucket in the database to
register all aliases, plus two buckets for each container (one to
hold connected CNI networks, a second to hold its aliases). The
aliases are only unique per-network, to the global and
per-container aliases buckets have a sub-bucket for each CNI
network that has aliases, and the aliases are stored within that
sub-bucket. Aliases are formatted as alias (key) to container ID
(value) in both cases.

Three DB functions are defined for aliases: retrieving current
aliases for a given network, setting aliases for a given network,
and removing all aliases for a given network.

with the cgroup manager the container is created with, so if the

To solve this, store the cgroup manager that created the
container in container configuration, so we can guarantee a
container with a systemd cgroup parent will always be started
with systemd cgroups.

Unfortunately, this is very difficult to test in CI, due to the
fact that we hard-code cgroup manager on all invocations of
