|\ | | | | auto update containers in systemd units
| * 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.

* | | Exec: use ErrorConmonReadPeter Hunt2020-03-03
| | | | | | | | | | | | | | | | | | | | | | | | Before, we were using -1 as a bogus value in podman to signify something went wrong when reading from a conmon pipe. However, conmon uses negative values to indicate the runtime failed, and return the runtime's exit code. instead, we should use a bogus value that is actually bogus. Define that value in the define package as MinInt32 (-1<< 31 - 1), which is outside of the range of possible pids (-1 << 31) Signed-off-by: Peter Hunt <pehunt@redhat.com>

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch allows users to specify the list of capabilities required to run their container image. Setting a image/container label "io.containers.capabilities=setuid,setgid" tells podman that the contained image should work fine with just these two capabilties, instead of running with the default capabilities, podman will launch the container with just these capabilties. If the user or image specified capabilities that are not in the default set, the container will print an error message and will continue to run with the default capabilities.

| * 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.

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | We can easily tell if we're going to deadlock by comparing lock IDs before actually taking the lock. Add a few checks for this in common places where deadlocks might occur. This does not yet cover pod operations, where detection is more difficult (and costly) due to the number of locks being involved being higher than 2. Also, add some error wrapping on the Podman side, so we can tell people to use `system renumber` when it occurs. Signed-off-by: Matthew Heon <matthew.heon@pm.me>

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