* createconfig: always cleanup a rootless containerGiuseppe Scrivano2019-01-10
| | | | | | | | | | | | | | | | the rootless container storage is always mounted in a different mount namespace, owned by the unprivileged user. Even if it is mounted, a process running in another namespace cannot reuse the already mounted storage. Make sure the storage is always cleaned up once the container terminates. This has worked with vfs since there is no real mounted storage. Closes: https://github.com/containers/libpod/issues/2112 Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>

| * apparmor: apply default profile at container initializationValentin Rothberg2019-01-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Apply the default AppArmor profile at container initialization to cover all possible code paths (i.e., podman-{start,run}) before executing the runtime. This allows moving most of the logic into pkg/apparmor. Also make the loading and application of the default AppArmor profile versio-indepenent by checking for the `libpod-default-` prefix and over-writing the profile in the run-time spec if needed. The intitial run-time spec of the container differs a bit from the applied one when having started the container, which results in displaying a potentially outdated AppArmor profile when inspecting a container. To fix that, load the container config from the file system if present and use it to display the data. Fixes: #2107 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

* pkg/hooks/exec: Include failed command in hook errorsW. Trevor King2019-01-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For example: $ cat /etc/containers/oci/hooks.d/test.json { "version": "1.0.0", "hook": { "path": "/bin/sh", "args": ["sh", "-c", "echo 'oh, noes!' >&2; exit 1"] }, "when": { "always": true }, "stages": ["precreate"] } $ podman run --rm docker.io/library/alpine echo 'successful container' error setting up OCI Hooks: executing [sh -c echo 'oh, noes!' >&2; exit 1]: exit status 1 The rendered command isn't in in the right syntax for copy/pasting into a shell, but it should be enough for the user to be able to locate the failing hook. They'll need to know their hook directories, but with the previous commits requiring explicit hook directories it's more likely that the caller is aware of them. And if they run at a debug level, they can see the lookups in the logs: $ podman --log-level=debug --hooks-dir=/etc/containers/oci/hooks.d run --rm docker.io/library/alpine echo 'successful container' 2>&1 | grep -i hook time="2018-12-02T22:15:16-08:00" level=debug msg="reading hooks from /etc/containers/oci/hooks.d" time="2018-12-02T22:15:16-08:00" level=debug msg="added hook /etc/containers/oci/hooks.d/test.json" time="2018-12-02T22:15:16-08:00" level=debug msg="hook test.json matched; adding to stages [precreate]" time="2018-12-02T22:15:16-08:00" level=warning msg="container 3695c6ba0cc961918bd3e4a769c52bd08b82afea5cd79e9749e9c7a63b5e7100: precreate hook: executing [sh -c echo 'oh, noes!' >&2; exit 1]: exit status 1" time="2018-12-02T22:15:16-08:00" level=error msg="error setting up OCI Hooks: executing [sh -c echo 'oh, noes!' >&2; exit 1]: exit status 1" Signed-off-by: W.

* hooks: Add pre-create hooks for runtime-config manipulationW. Trevor King2019-01-08
| | | | | | | | | | | | | | | | | | | | | | | There's been a lot of discussion over in [1] about how to support the NVIDIA folks and others who want to be able to create devices (possibly after having loaded kernel modules) and bind userspace libraries into the container. Currently that's happening in the middle of runc's create-time mount handling before the container pivots to its new root directory with runc's incorrectly-timed prestart hook trigger [2]. With this commit, we extend hooks with a 'precreate' stage to allow trusted parties to manipulate the config JSON before calling the runtime's 'create'. I'm recycling the existing Hook schema from pkg/hooks for this, because we'll want Timeout for reliability and When to avoid the expense of fork/exec when a given hook does not need to make config changes [3].

* / add container-init supportValentin Rothberg2019-01-04
|/ | | | | | | | | | | | | | | | | | | Add support for executing an init binary as PID 1 in a container to forward signals and reap processes. When the `--init` flag is set for podman-create or podman-run, the init binary is bind-mounted to `/dev/init` in the container and "/dev/init --" is prepended to the container's command. The default base path of the container-init binary is `/usr/libexec/podman` while the default binary is catatonit [1]. This default can be changed permanently via the `init_path` field in the `libpod.conf` configuration file (which is recommended for packaging) or temporarily via the `--init-path` flag of podman-create and podman-run.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
