* Merge pull request #1846 from cgwalters/netns-dns-localhostOpenShift Merge Robot2018-11-28
|\ | | | | Use host's resolv.conf if no network namespace enabled
| * Use host's resolv.conf if no network namespace enabledColin Walters2018-11-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | My host system runs Fedora Silverblue 29 and I have NetworkManager's `dns=dnsmasq` setting enabled, so my `/etc/resolv.conf` only has `127.0.0.1`. I also run my development podman containers with `--net=host` for various reasons. If we have a host network namespace, there's no reason not to just use the host's nameserver configuration either. This fixes e.g. accessing content on a VPN, and is also faster since the container is using cached DNS. I know this doesn't solve the bigger picture issue of localhost-DNS conflicting with bridged networking, but that's far more involved, probably requiring a DNS proxy in the container. This patch makes my workflow a lot nicer and was easy to write. Signed-off-by: Colin Walters <walters@verbum.org>

| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | Container images can be created without passwd or group file, currently if one of these containers gets run with a --user flag the container blows up complaining about t a missing /etc/passwd file.

| | | | | | | | | | | | | | | | | | we are currently using something like /run/user/UID/run as runroot, as it is already done by Buildah.

| | | | | | | | | | | | | | | | | | | | | | for the purposes of performance and security, we use securejoin to contstruct the root fs's path so that symlinks are what they appear to be and no pointing to something naughty. then instead of chrooting to parse /etc/passwd|/etc/group, we now use the runc user/group methods which saves us quite a bit of performance.

* Mount proper cgroup for systemd to manage inside of the container.Daniel J Walsh2018-10-15
| | | | | | | | | | | | We are still requiring oci-systemd-hook to be installed in order to run systemd within a container. This patch properly mounts /sys/fs/cgroup/systemd/libpod_parent/libpod-UUID on /sys/fs/cgroup/systemd inside of container. Since we need the UUID of the container, we needed to move Systemd to be a config option of the container. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | the issue is caused by the Go Runtime that messes up with the process signals, overriding SIGSETXID and SIGCANCEL which are used internally by glibc. They are used to inform all the threads to update their stored uid/gid information. This causes a hang on the set*id glibc wrappers since the handler installed by glibc is never invoked. Since we are running with only one thread, we don't really need to update other threads or even the current thread as we are not using getuid/getgid before the execvp.

* Drop libnetwork vendor and move the code into pkg/Matthew Heon2018-10-04
| | | | | | | | | | | The vendoring issues with libnetwork were significant (it was dragging in massive amounts of code) and were just not worth spending the time to work through. Highly unlikely we'll ever end up needing to update this code, so move it directly into pkg/ so we don't need to vendor libnetwork. Make a few small changes to remove the need for the remainder of libnetwork. Signed-off-by: Matthew Heon <matthew.heon@gmail.com>

* | Add ContainerStateExited and OCI delete() in cleanup()Matthew Heon2018-10-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To work better with Kata containers, we need to delete() from the OCI runtime as a part of cleanup, to ensure resources aren't retained longer than they need to be. To enable this, we need to add a new state to containers, ContainerStateExited. Containers transition from ContainerStateStopped to ContainerStateExited via cleanupRuntime which is invoked as part of cleanup(). A container in the Exited state is identical to Stopped, except it has been removed from the OCI runtime and thus will be handled differently when initializing the container.
