* Set log driver for compatability containersbaude2021-01-20
| | | | | | | | | | | | | | | when using the compatibility api to create containers, now reflect the use of k8s-file as json-file so that clients, which are unaware of k8s-file, can work. specifically, if the container is using k8s-file as the log driver, we change the log type in container inspection to json-file. These terms are used interchangably in other locations in libpod/podman. this fixes log messages in compose as well. [NO TESTS NEEDED] Signed-off-by: baude <bbaude@redhat.com>
* specgen: improve heuristic for /sys bind mountGiuseppe Scrivano2021-01-15
| | | | | | | | | | | | | partially revert 95c45773d7dbca2880152de681c81f0a2afec99b restrict the cases where /sys is bind mounted from the host. The heuristic doesn't detect all the cases where the bind mount is not necessary, but it is an improvement on the previous version where /sys was always bind mounted for rootless containers unless --net none was specified.

| | | | | | | | | | | | | | | | | | | | | | | | We can't mount sysfs as rootless unless we manage the network namespace. Problem: slirp4netns is now creating and managing a network namespace separate from the OCI runtime, so we can't mount sysfs in many circumstances. The `crun` OCI runtime will automatically handle this by falling back to a bind mount, but `runc` will not, so we didn't notice until RHEL gating tests ran on the new branch.

* / Do not use "true" after "syslog" in exit commandsMatthew Heon2020-12-01
|/ | | | | | | | | | | | | | | | | | | | | Instead of being interpreted as an argument to the boolean flag, the 'true' is being intepreted as the Podman command to be run - so we're trying to run `podman true`, which does not exist. This causes the cleanup command to fail when `--log-level=debug` is set, so containers are not cleaned up or removed. This problem is easily reproduced with any command combining the `--rm`, `-d`, and `--log-level=debug` flags - the command will execute and exit, but the container will not be removed. Separate, but worth looking into later: the errors we get on trying `podman true` with any flags are terrible - if you just type `podman true` you get a quite sane "Unrecognized command" error, but if you try `podman true --rm` you get an "unknown flag --rm" error - which makes very little sense given the command itself doesn't exist.

The PVC basically contains criterias that k8s then use to select which storage source it will use for the volume.
