* rootless: do not override /dev/pts if not neededGiuseppe Scrivano2019-02-06
| | | | | | | | | | when running in rootless mode we were unconditionally overriding /dev/pts to take ride of gid=5. This is not needed when multiple gids are present in the namespace, which is always the case except when running the tests suite with only one mapping. So change it to check how many gids are present before overriding the default mount. Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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differs a bit from the applied one when having started the container, which results in displaying a potentially outdated AppArmor profile when inspecting a container.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>

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