* allow exec to read files of environment variablesbaude2019-12-11
| | | | | | | | | we want the ability to define environment variables in files for the exec command. Fixes: #1782408 Signed-off-by: baude <bbaude@redhat.com>

* Allow users to disable detach keysDaniel J Walsh2019-11-05
| | | | | | | | | | If user specifies --detach-keys="", this will disable the feature. Adding define.DefaultDetachKeys to help screen to help identify detach keys. Updated man pages with additonal information. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>
* move editing of exitCode to runtimePeter Hunt2019-07-23
| | | | | | | | | There's no way to get the error if we successfully get an exit code (as it's just printed to stderr instead). instead of relying on the error to be passed to podman, and edit based on the error code, process it on the varlink side instead Also move error codes to define package Signed-off-by: Peter Hunt <pehunt@redhat.com>

* configure runtime without storebaude2019-07-01
| | | | | | | | | some podman commands do not require the use of a container/image store. in those cases, it is more effecient to not open the store, because that results in having to also close the store which can be costly when the system is under heavy write I/O loads.

* libpod removal from main (phase 2)baude2019-06-27
| | | | | | this is phase 2 for the removal of libpod from main. Signed-off-by: baude <bbaude@redhat.com>
* remove libpod from mainbaude2019-06-25
| | | | | | | | | | | | | the compilation demands of having libpod in main is a burden for the remote client compilations. to combat this, we should move the use of libpod structs, vars, constants, and functions into the adapter code where it will only be compiled by the local client. this should result in cleaner code organization and smaller binaries. it should also help if we ever need to compile the remote client on non-Linux operating systems natively (not cross-compiled).

* If container is not in correct state podman exec should exit with 126Daniel J Walsh2019-06-12
| | | | | | | | | | | | This way a tool can determine if the container exists or not, but is in the wrong state. Since 126 is documeted as: **_126_** if the **_contained command_** cannot be invoked It makes sense that the container would exit with this state. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>

* Fix segfaults attribute to missing optionsbaude2019-04-15
| | | | | | | | | In cases where the remote client culls options to a command, we need to be sure that the lookup for that flag does not result in a nil pointer. To do so, we add a Remote attribute to the podman struct and then cli helper funcs are now aware they are remote. Signed-off-by: baude <bbaude@redhat.com>
* rootless: use a single user namespaceGiuseppe Scrivano2019-04-01
| | | | | | | | | | | | | | | | | | | | | simplify the rootless implementation to use a single user namespace for all the running containers. This makes the rootless implementation behave more like root Podman, where each container is created in the host environment. There are multiple advantages to it: 1) much simpler implementation as there is only one namespace to join. 2) we can join namespaces owned by different containers. 3) commands like ps won't be limited to what container they can access as previously we either had access to the storage from a new namespace or access to /proc when running from the host. 4) rootless varlink works. 5) there are only two ways to enter in a namespace, either by creating a new one if no containers are running or joining the existing one from any container. Containers created by older Podman versions must be restarted. Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>
* rootless: remove SkipStorageSetup()Giuseppe Scrivano2019-04-01
| | | | | | | | in the few places where we care about skipping the storage initialization, we can simply use the process effective UID, instead of relying on a global boolean flag. Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>
* rootless: fix regression when using exec on old containersGiuseppe Scrivano2019-03-27
| | | | | | | | | fallback to the previous behavior of joining only the user namespace, when we cannot join the conmon userns+mount namespaces. Closes: https://github.com/containers/libpod/issues/2673 Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>

* preparation for remote-client create containerbaude2019-03-11
| | | | | | | | | to prepare for being able to remotely run a container, we need to perform a refactor to get code out of main because it is not reusable. the shared location is a good starting spot though eventually some will likely end up in pkg/spec/ at some point.

| * rootless: exec join the user+mount namespaceGiuseppe Scrivano2019-03-07
| | | | | | | | | | | | | | | | | | | | | | it is not enough to join the user namespace where the container is running. We also need to join the mount namespace so that we can correctly look-up inside of the container rootfs. This is necessary to lookup the mounted /etc/passwd file when --user is specified.

| | | | | | | | | | | | | | | | | Don't print potentially verbose help messages in case of usage errors, but print only the usage error followed by a pointer to the command's help.

* rootless: fix execGiuseppe Scrivano2018-08-26
| | | | | | | | | | | | | | | | | | | | | We cannot re-exec into a new user namespace to gain privileges and access an existing as the new namespace is not the owner of the existing container. "unshare" is used to join the user namespace of the target container. The current implementation assumes that the main process of the container didn't create a new user namespace. Since in the setup phase we are not running with euid=0, we must skip the setup for containers/storage.

* Stage3 Image Librarybaude2018-03-14
| | | | | | | | | | | | | This represents the stage3 implementation for the image library. At this point, we are moving the image-centric functions to pkg/image including migration of args and object-oriented references. This is a not a one-for-one migration of funcs and some funcs will need to continue to reside in runtime_img as they are overly specific to libpod and probably not useful to others.
