* auto updatesValentin Rothberg2020-03-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support to auto-update containers running in systemd units as generated with `podman generate systemd --new`. `podman auto-update` looks up containers with a specified "io.containers.autoupdate" label (i.e., the auto-update policy). If the label is present and set to "image", Podman reaches out to the corresponding registry to check if the image has been updated. We consider an image to be updated if the digest in the local storage is different than the one of the remote image. If an image must be updated, Podman pulls it down and restarts the container. Note that the restarting sequence relies on systemd. At container-creation time, Podman looks up the "PODMAN_SYSTEMD_UNIT" environment variables and stores it verbatim in the container's label. This variable is now set by all systemd units generated by `podman-generate-systemd` and is set to `%n` (i.e., the name of systemd unit starting the container). This data is then being used in the auto-update sequence to instruct systemd (via DBUS) to restart the unit and hence to restart the container. Note that this implementation of auto-updates relies on systemd and requires a fully-qualified image reference to be used to create the container. This enforcement is necessary to know which image to actually check and pull. If we used an image ID, we would not know which image to check/pull anymore.

* Add validate() for containersMatthew Heon2020-03-02
| | | | | | | | | | | | | | | | | | | Until now, we've been validating every part of container configuration through the With... functions that set the options. This if fine when we are just validating the options to an individual function, but things get complicated once we need to validate conflicts between different options. We don't know the order in which things were passed, so we need the validation on both of the potential options that can conflict, resulting in significant code duplication. To solve this, add a validate() function for containers, and use this to check whether everything is in a good state. We can probably move more into this function (there are other parts of container creation that also do validation of a sort) but this is a good start to simplifying our options.

* Remove ImageVolumes from databaseMatthew Heon2020-02-21
| | | | | | | | | | | | | | Before Libpod supported named volumes, we approximated image volumes by bind-mounting in per-container temporary directories. This was handled by Libpod, and had a corresponding database entry to enable/disable it. However, when we enabled named volumes, we completely rewrote the old implementation; none of the old bind mount implementation still exists, save one flag in the database. With nothing remaining to use it, it has no further purpose. Signed-off-by: Matthew Heon <mheon@redhat.com>

| | | | | | | | | | This adds network-related options to the pod in the database. We are going to add the CLI frontend in further patches.

* Deprecate & remove IsCtrSpecific in favor of IsAnonMatthew Heon2020-01-29
| | | | | | | | | | | | | | | | | | | In Podman 1.6.3, we added support for anonymous volumes - fixing our old, broken support for named volumes that were created with containers. Unfortunately, this reused the database field we used for the old implementation, and toggled volume removal on for `podman run --rm` - so now, we were removing *named* volumes created with older versions of Podman. We can't modify these old volumes in the DB, so the next-safest thing to do is swap to a new field to indicate volumes should be removed. Problem: Volumes created with 1.6.3 and up until this lands, even anonymous volumes, will not be removed. However, this is safer than removing too many volumes, as we were doing before.

* 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).

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>

* 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.
