* container config: add CreateCommandValentin Rothberg2019-12-13
| | | | | | | | | | | | | | | | | | Store the full command plus arguments of the process the container has been created with. Expose this data as a `Config.CreateCommand` field in the container-inspect data as well. This information can be useful for debugging, as we can find out which command has created the container, and, if being created via the Podman CLI, we know exactly with which flags the container has been created with. The immediate motivation for this change is to use this information for `podman-generate-systemd` to generate systemd-service files that allow for creating new containers (in contrast to only starting existing ones).

* Merge pull request #4493 from mheon/add_removing_stateOpenShift Merge Robot2019-12-02
|\ | | | | Add ContainerStateRemoving
| * Add ContainerStateRemovingMatthew Heon2019-11-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When Libpod removes a container, there is the possibility that removal will not fully succeed. The most notable problems are storage issues, where the container cannot be removed from c/storage. When this occurs, we were faced with a choice. We can keep the container in the state, appearing in `podman ps` and available for other API operations, but likely unable to do any of them as it's been partially removed. Or we can remove it very early and clean up after it's already gone. We have, until now, used the second approach. The problem that arises is intermittent problems removing storage. We end up removing a container, failing to remove its storage, and ending up with a container permanently stuck in c/storage that we can't remove with the normal Podman CLI, can't use the name of, and generally can't interact with. A notable cause is when Podman is hit by a SIGKILL midway through removal, which can consistently cause `podman rm` to fail to remove storage. We now add a new state for containers that are in the process of being removed, ContainerStateRemoving. We set this at the beginning of the removal process. It notifies Podman that the container cannot be used anymore, but preserves it in the DB until it is fully removed. This will allow Remove to be run on these containers again, which should successfully remove storage if it fails. Fixes #3906 Signed-off-by: Matthew Heon <mheon@redhat.com>

* add libpod/configValentin Rothberg2019-10-31
| | | | | | | | | | | | Refactor the `RuntimeConfig` along with related code from libpod into libpod/config. Note that this is a first step of consolidating code into more coherent packages to make the code more maintainable and less prone to regressions on the long runs. Some libpod definitions were moved to `libpod/define` to resolve circular dependencies. Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

* Migrate can move containers to a new runtimeMatthew Heon2019-10-10
| | | | | | | | | | | | This is a horrible hack to work around issues with Fedora 31, but other distros might need it to, so we'll move it upstream. I do not recommend this functionality for general use, and the manpages and other documentation will reflect this. But for some upgrade cases, it will be the only thing that allows for a working system. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* Update c/image to v4.0.1 and buildah to 1.11.3Miloslav Trmač2019-10-04
| | | | | | | | | | | | | | This requires updating all import paths throughout, and a matching buildah update to interoperate. I can't figure out the reason for go.mod tracking github.com/containers/image v3.0.2+incompatible // indirect ((go mod graph) lists it as a direct dependency of libpod, but (go list -json -m all) lists it as an indirect dependency), but at least looking at the vendor subdirectory, it doesn't seem to be actually used in the built binaries.

* Set base mount options for bind mounts from base systemMatthew Heon2019-08-28
| | | | | | | | | | | | | | | | | | If I mount, say, /usr/bin into my container - I expect to be able to run the executables in that mount. Unconditionally applying noexec would be a bad idea. Before my patches to change mount options and allow exec/dev/suid being set explicitly, we inferred the mount options from where on the base system the mount originated, and the options it had there. Implement the same functionality for the new option handling. There's a lot of performance left on the table here, but I don't know that this is ever going to take enough time to make it worth optimizing. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* Add support for 'exec', 'suid', 'dev' mount flagsMatthew Heon2019-08-28
| | | | | | | | | | | | | | | | | | Previously, we explicitly set noexec/nosuid/nodev on every mount, with no ability to disable them. The 'mount' command on Linux will accept their inverses without complaint, though - 'noexec' is counteracted by 'exec', 'nosuid' by 'suid', etc. Add support for passing these options at the command line to disable our explicit forcing of security options. This also cleans up mount option handling significantly. We are still parsing options in more than one place, which isn't good, but option parsing for bind and tmpfs mounts has been unified.

| | | | | | | | | 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.

* 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).
