|\ | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | due to a change in golang-1.14 and it's changes to make go funcs with tight loops preemptive, signals are now getting "through" that never were before. From the golang-1.14 announce: Goroutines are now asynchronously preemptible. As a result, loops without function calls no longer potentially deadlock the scheduler or significantly delay garbage collection. This is supported on all platforms except windows/arm, darwin/arm, js/wasm, and plan9/*. A consequence of the implementation of preemption is that on Unix systems, including Linux and macOS systems, programs built with Go 1.14 will receive more signals than programs built with earlier releases. This means that programs that use packages like syscall or golang.org/x/sys/unix will see more slow system calls fail with EINTR errors. Those programs will have to handle those errors in some way, most likely looping to try the system call again. For more information about this see man 7 signal for Linux systems or similar documentation for other systems. Fixes #5483 Signed-off-by: Brent Baude <bbaude@redhat.com>

| * | generate systemd: add `default.target` to INSTALLValentin Rothberg2020-03-09
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When enabling a systemd service we can specify which target will start it by specifying it in the `[INSTALL]` section. In case of root, this is commonly set to `multi-user.target` which is used to start other essential system services such as the network manager, D-BUS and more. However, the `multi-user.target` is not enough on all systems, especially when running rootless and enabling user services. Multiple users have reported issues that there isn't even an attempt to start the service. Setting the INSTALL target to `default.target` will fix the rootless case. However, `default.target` may vary among systems. Fedora Workstation, for instance, sets the `default.target` to the graphical target (i.e., runlevel 5) while Fedora Server sets it to `multi-user.target` which is on runlevel 2 and hence way earlier in the startup sequence. As INSTALL allows for specifying multiple INSTALL targets, we can set it to `multi-user.target` to continue supporting existing workloads AND to `default.target` which MAY redundantly attempt to start it at a later point; effectively a NOP for the root case and essential for rootless.

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.
