Load NAT modules to fix tests involving CRIU
|
| |/
|
|
|
|
|
|
|
| |
CRIU uses iptables to lock and unlock the network during checkpoint and
restore. If Podman is running in Podman the automatic loading of modules
does not work and thus this commit pre-loads the necessary modules to
make sure the checkpoint test cases are not failing.

Added option to keep container running after checkpointing
|
| | |
| |
| |
| |
| |
| |
| |
| | |
This adds the '--leave-running, -R' to the container-checkpoint man
page. As the information for '--all, -a' and '--latest, -l' was also
still missing it is included in this commit.

CRIU supports to leave processes running after checkpointing:
-R|--leave-running leave tasks in running state after checkpoint
runc also support to leave containers running after checkpointing:
--leave-running leave the process running after checkpointing
With this commit the support to leave a container running after
checkpointing is brought to Podman:
--leave-running, -R leave the container running after writing checkpoint to disk
Now it is possible to checkpoint a container at some point in time
without stopping the container. This can be used to rollback the
container to an early state:
$ podman run --tmpfs /tmp --name podman-criu-test -d docker://docker.io/yovfiatbeb/podman-criu-test
$ curl 10.88.64.253:8080/examples/servlets/servlet/HelloWorldExample
3
$ podman container checkpoint -R -l
$ curl 10.88.64.253:8080/examples/servlets/servlet/HelloWorldExample
4
$ curl 10.88.64.253:8080/examples/servlets/servlet/HelloWorldExample
5
$ podman stop -l
$ podman container restore -l
$ curl 10.88.64.253:8080/examples/servlets/servlet/HelloWorldExample
4
So after checkpointing the container kept running and was stopped after
some time. Restoring this container will restore the state right at the
checkpoint.

For upcoming changes to the Checkpoint() functions this commit switches
checkpoint options from a boolean to a struct, so that additional
options can be passed easily to Checkpoint() without changing the
function parameters all the time.

YAML that will allow you to run the container in a kubernetes environment. When
The YAML description will always "wrap" a container in a simple v1.Pod description.
Tests and further documentation will be added in additional PRs.
This function should be considered very much "under heavy development" at
this point.

we need to allow users to expose ports to the host for the purposes
of networking, like a webserver. the port exposure must be done at
the time the pod is created.
strictly speaking, the port exposure occurs on the infra container.

Previously it was required to call the verify, unit, and integration
scripts in order to build/install dependencies, and libpod. This
wastes time during the (optional) system-testing, since the
actual unit/integration testing is also happening in parallel.
Consolidate only the distribution-specific build steps into the
system-testing script. This way, only the required steps are performed
in their respective (parallel) tasks.

Previously, several magic strings were in place to affect cirrus-ci
operations. Two were buried within scripts. One to optionally
execute system-tests within a PR. Another to avoid re-building
cache-images upon every merge.
Move these magic strings out into the open, buy locating their
logic up-front in the ``.cirrus.yml`` file. This improves
readability and reduces surprise/astonishment at runtime.

While we have these string literals on repeated on multiple places in the
library, I cannot see real tangible benefit extracting these to constants
considering following facts:
(1) while 'unknown' or 'host' are repeated, they are often times used in
different context and thus perhaps worth extra const per each use.
(2) while these string literals repeat, the library is full of string literals
with special meaning that should be made constants too
(3) readability would suffer

We fixated on old metalinter dependency in past based on experience of
metalinter being oftentimes broke and hence broking our build. See
762f508d9ca97cdbaee6053b663e98aee9cae081 in cri-o for more details.
Now, dated metalinter is messing up with my environment (like it is
panicing on containters/storage) so let's see if we can move to more
current version of metalinter.

Since we use buildah containers for the build process, the
user will not know if we have any buildah containers lingering
due to a failed build. Setting this to true by default till
we figure out a better way to solve this.
