Add history names to image inspect data
|

| |
| |
| |
| |
| |

During writing the tests I found it would be probably useful to have the
tag history part of the inspect data.

api/handlers will have all the code related to implementing the end
points.
api/server/register_* will contain the methods for registering
endpoints. Additionally, they will have the comments for generating the
swagger spec file.
See api/handlers/version.go for a small example handler,

In a largely anticlimatic solution to the saga of piped input from conmon, we come to this solution.
When we pass the Stdin stream to the exec.Command structure, it's immediately consumed and lost, instead of being consumed through CopyDetachable().
When we don't pass -i in, conmon is not told to create a masterfd_stdin, and won't pass anything to the container.
With both, we can do
echo hi | podman exec -til cat
and get the expected hi

RootlessKit port forwarder has a lot of advantages over the slirp4netns port forwarder:
* Very high throughput.
Benchmark result on Travis: socat: 5.2 Gbps, slirp4netns: 8.3 Gbps, RootlessKit: 27.3 Gbps
(https://travis-ci.org/rootless-containers/rootlesskit/builds/597056377)
* Connections from the host are treated as 127.0.0.1 rather than 10.0.2.2 in the namespace.
No UDP issue (#4586)
* No tcp_rmem issue (#4537)
* Probably works with IPv6. Even if not, it is trivial to support IPv6. (#4311)
* Easily extensible for future support of SCTP
* Easily extensible for future support of `lxc-user-nic` SUID network
RootlessKit port forwarder has been already adopted as the default port forwarder by Rootless Docker/Moby,
and no issue has been reported AFAIK.
As the port forwarder is imported as a Go package, no `rootlesskit` binary is required for Podman.
Fix #4586
May-fix #4559
Fix #4537
May-fix #4311

Currently, if a user requests the size on a container (inspect --size -t container),
the SizeRw does not show up if the value is 0. It's because InspectContainerData is
defined as int64 and there is an omit when empty.
We do want to display it even if the value is empty. I have changed the type of SizeRw to be a pointer to an int64 instead of an int64. It will allow us todistinguish the empty value to the missing value.
I updated the test "podman inspect container with size" to ensure we check thatSizeRw is displayed correctly.

Remove volumes after containers in pod remove

When trying to reproduce #4704 I noticed that the named volumes
from the Postgres containers in the reproducer weren't being
removed by `podman pod rm -f` saying that the container they were
attached to was still in use. This was rather odd, considering
they were only in use by one container, and that container was in
the process of being removed with the pod.
After a bit of tracing, I realized that the cause is the ordering
of container removal when we remove a pod. Normally, it's done
in removeContainer() before volume removal (which is the last
thing in that function). However, when we are removing a pod, we
remove containers all at once, after removeContainer has already
finished - meaning the container still exists when we try to
remove its volumes, and thus the volume can't be removed.
Solution: collect a list of all named volumes in use by the pod,
and remove them all at once after every container in the pod is
gone. This ensures that there are no dependency issues.

Store the full command plus arguments of the process the container has
been created with. Expose this data as a `Config.CreateCommand` field
in the container-inspect data as well.
This information can be useful for debugging, as we can find out which
command has created the container, and, if being created via the Podman
CLI, we know exactly with which flags the container has been created
with.
The immediate motivation for this change is to use this information for
`podman-generate-systemd` to generate systemd-service files that allow
for creating new containers (in contrast to only starting existing
ones).

Correctly export the root file-system changes

When doing a checkpoint with --export the root file-system diff was not
working as expected. Instead of getting the changes from the running
container to the highest storage layer it got the changes from the
highest layer to that parent's layer. For a one layer container this
could mean that the complete root file-system is part of the checkpoint.
With this commit this changes to use the same functionality as 'podman
diff'. This actually enables to correctly diff the root file-system
including tracking deleted files.
This also removes the non-working helper functions from libpod/diff.go.

The earlier attempt to re-add config migration only worked with
user-specified configs (podman run --config). This version works
more in line with that we want - the first rootless config file
will be changed from runc to crun.
Verified on my system after an F31 migration - everything seems
to be working well.

We currently rely on exec sessions being removed from the state
by the Exec() API itself, on detecting the session stopping. This
is not a reliable method, though. The Podman frontend for exec
could be killed before the session ended, or another Podman
process could be holding the lock and prevent update (most
notable in `run --rm`, when a container with an active exec
session is stopped).
To resolve this, add a function to reap active exec sessions from
the state, and use it on cleanup (to clear sessions after the
container stops) and remove (to do the same when --rm is passed).
This is a bit more complicated than it ought to be because Kata
and company exist, and we can't guarantee the exec session has a
PID on the host, so we have to plumb this through to the OCI
runtime.

to make things more effecient for the api work we are doing, we should
process image filters internally (as opposed to in main). this allows
for better api responses and more closely affiliated functions.

In the process, make everything in the config omitempty in TOML.
We're seeing issues (notably [1]) where, after rewriting
libpod.conf, fields that were not previously populated are
written - and, because they were not previously written, they are
included as empty. This is unfortunately different from not
included at all - it means that we need to assume the user
explicitly unset the value, and we can't use defaults. Setting
omitempty prevents us from writing things that should not be
written as they were not set originally.

Fix parsing for arrays of values in image changes

Return types had to change a bit for this, but since we can wrap
the old v1.ImageConfig, changes are overall not particularly bad.
At present, I believe this only works with commit, not import.
This matches how things were before we changed to the new parsing
so I think this is fine.

It turns out we had two independent parsing impkementations for
Dockerfile instructions out of --change. My previous commit fixed
the one used in --change, but as I discovered to my dismay,
commit used a different implementation. Remove that and use the
new parsing implementation instead.
While we're at it, fix some bugs in the current commit code. The
addition of anonymous named volumes to Libpod recently means we
can now include those in the image config when committing. Some
changes (VOLUME, ENV, EXPOSE, LABEL) previously cleared the
config of the former image when used; Docker does not do this, so
I removed that behavior.
Still needs fixing: the new implementation does not support
ONBUILD, while the old one did.

Allow chained network namespace containers
|
| | |
| |
| |
| |
| |
| |
| |
| |
| |
| |
| |
| |
| | |
The code currently assumes that the container we delegate network
namespace to will never further delegate to another container, so
when looking up things like /etc/hosts and /etc/resolv.conf we
won't pull the correct files from the chained dependency. The
changes to resolve this are relatively simple - just need to keep
looking until we find a container without NetNsCtr set.

After a restart, pods and containers both run a refresh()
function to prepare to run after a reboot. Until now, volumes
have not had a similar function, because they had no per-boot
setup to perform.
Unfortunately, this was not noticed when in-memory locking was
introduced to volumes. The refresh() routine is, among other
things, responsible for ensuring that locks are reserved after a
reboot, ensuring they cannot be taken by a freshly-created
container, pod, or volume. If this reservation is not done, we
can end up with two objects using the same lock, potentially
needing to lock each other for some operations - classic recipe
for deadlocks.
Add a refresh() function to volumes to perform lock reservation
and ensure it is called as part of overall refresh().

do not change the runtime error to be lowercase, but use a case
insensitive regex matching. In this way the original error from the
OCI runtime is reported back.

If the container is running and we need to get its netns and
can't, that is a serious bug deserving of errors.
If it's not running, that's not really a big deal. Log an error
and continue.
