* new "image" mount typeValentin Rothberg2020-10-29
| | | | | | | | | | | | | | Add a new "image" mount type to `--mount`. The source of the mount is the name or ID of an image. The destination is the path inside the container. Image mounts further support an optional `rw,readwrite` parameter which if set to "true" will yield the mount writable inside the container. Note that no changes are propagated to the image mount on the host (which in any case is read only). Mounts are overlay mounts. To support read-only overlay mounts, vendor a non-release version of Buildah. Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
* container create: record correct image nameValentin Rothberg2020-10-21
| | | | | | | | | | Record the correct image name when creating a container by using the resolved image name if present. Otherwise, default to using the first available name or an empty string in which case the image must have been referenced by ID. Fixes: #8082 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

| * refactor api compatibility container creation to specgenbaude2020-10-20
| | | | | | | | | | | | when using the compatibility layer to create containers, it used code paths to the pkg/spec which is the old implementation of containers. it is error prone and no longer being maintained. rather that fixing things in spec, migrating to specgen usage seems to make the most sense. furthermore, any fixes to the compat create will not need to be ported later.

|\ \ | |/ |/| Ensure that hostname is added to hosts with net=host
| * Ensure that hostname is added to hosts with net=hostMatthew Heon2020-10-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a container uses --net=host the default hostname is set to the host's hostname. However, we were not creating any entries in `/etc/hosts` despite having a hostname, which is incorrect. This hostname, for Docker compat, will always be the hostname of the host system, not the container, and will be assigned to IP 127.0.1.1 (not the standard localhost address). Also, when `--hostname` and `--net=host` are both passed, still use the hostname from `--hostname`, not the host's hostname (we still use the host's hostname by default in this case if the `--hostname` flag is not passed). Fixes #8054 Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* | Fix host to container port mapping for simple rangesSascha Grunert2020-10-19
|/ | | | | | | | | | | | | | | | | This fixes the issue that a simple port range should map to a random port range from the host to the container, if no host port range is specified. For example this fails without applying the patch: ``` > podman run -it -p 6000-6066 alpine Error: cannot listen on the TCP port: listen tcp4 :53: bind: address already in use ``` The issue is that only the first port is randomly chosen and all following in the range start by 0 and increment. This is now fixed by tracking the ranges and then incrementing the random port if necessary. Signed-off-by: Sascha Grunert <sgrunert@suse.com>

| * Remove excessive error wrappingKir Kolyshkin2020-10-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In case os.Open[File], os.Mkdir[All], ioutil.ReadFile and the like fails, the error message already contains the file name and the operation that fails, so there is no need to wrap the error with something like "open %s failed". While at it - replace a few places with os.Open, ioutil.ReadAll with ioutil.ReadFile. - replace errors.Wrapf with errors.Wrap for cases where there are no %-style arguments.

* run/create: record raw imageValentin Rothberg2020-09-15
| | | | | | | | | | | | | | | | | | | | | | Record the user-specified "raw" image name in the SpecGenerator, so we can pass it along to the config when creating a container. We need a separate field as the image name in the generator may be set to the ID of the previously pulled image - ultimately the cause of #7404. Reverting the image name from the ID to the user input would not work since "alpine" for pulling iterates over the search registries in the registries.conf but looking up "alpine" normalizes to "localhost/alpine". Recording the raw-image name directly in the generator was the best of the options I considered as no hidden magic from search registries or normalizations (that may or may not change in the future) can interfere. The auto-update backend enforces that the raw-image name is a fully-qualified reference, so we need to worry about that in the front end.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most Libpod containers are made via `pkg/specgen/generate` which includes code to generate an appropriate exit command which will handle unmounting the container's storage, cleaning up the container's network, etc. There is one notable exception: pod infra containers, which are made entirely within Libpod and do not touch pkg/specgen. As such, no cleanup process, network never cleaned up, bad things can happen. There is good news, though - it's not that difficult to add this, and it's done in this PR. Generally speaking, we don't allow passing options directly to the infra container at create time, but we do (optionally) proxy a pre-approved set of options into it when we create it. Add ExitCommand to these options, and set it at time of pod creation using the same code we use to generate exit commands for normal containers.
