* 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>
* pkg, cgroups: add initial support for cgroup v2Giuseppe Scrivano2019-06-26
| | | | | | | | | | | | | | | | | This is an initial implementation of cgroup v2 support for pkg/cgroups. It currently works with crun, with this patch: https://github.com/giuseppe/crun/pull/49). It adds the pieces for: - set PID limit to 1 - retrieve stats so that "podman stats" work. the only missing part is the support for reading per CPU stats (that is cpuacct.usage_percpu on cgroup v1), so for now it always returns an empty result.

* pkg: new package cgroupsGiuseppe Scrivano2019-06-26
| | | | | | | | | | | | | | | | | | provide a package for managing cgroups. This is not supposed to be a complete implementation with all the features supported by cgroups, but it is a minimal implementation designed around what libpod needs and it is currently using. For example, it is currently possible to Apply only the pids limit, as it is used by libpod for stopping containers, any other Apply will just fail. The main goal here is to have a minimal library where we have full control, so we can start playing with cgroup v2. When the need arises, we can add more features.

* 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).

| | | | | | | | | | | | | | | | | | | | | | when using podman-remote on windows, the bridge format must account for how windows deals with escape quoting. in this case, it does not need any. also, reduced duplicated code around generating the bridge endpoint for the unix and windows platforms.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We made changes earlier that empty storage options when setting storage driver explicitly. Unfortunately, this breaks rootless cleanup commands, as they lose the fuse-overlayfs mount program path. Fix this by passing along the storage options to the cleanup process. Also, fix --syslog, which was broken a while ago (probably when we broke up main to add main_remote). Fixes #3326 Signed-off-by: Matthew Heon <mheon@redhat.com>

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This flag switches to removing containers directly from c/storage and is mostly used to remove orphan containers. It's a superior solution to our former one, which attempted removal from storage under certain circumstances and could, under some conditions, not trigger. Also contains the beginning of support for storage in `ps` but wiring that in is going to be a much bigger pain. Fixes #3329. Signed-off-by: Matthew Heon <matthew.heon@pm.me>

| * | migration: add possibility to restore a container with a new nameAdrian Reber2019-06-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The option to restore a container from an external checkpoint archive (podman container restore -i /tmp/checkpoint.tar.gz) restores a container with the same name and same ID as id had before checkpointing. This commit adds the option '--name,-n' to 'podman container restore'. With this option the restored container gets the name specified after '--name,-n' and a new ID. This way it is possible to restore one container multiple times. If a container is restored with a new name Podman will not try to request the same IP address for the container as it had during checkpointing. This implicitly assumes that if a container is restored from a checkpoint archive with a different name, that it will be restored multiple times and restoring a container multiple times with the same IP address will fail as each IP address can only be used once.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If restoring a container from a checkpoint it was necessary that the image the container is based was already available (podman pull).

| * | Added support to migrate containersAdrian Reber2019-06-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds an option to the checkpoint command to export a checkpoint into a tar.gz file as well as importing a checkpoint tar.gz file during restore. With all checkpoint artifacts in one file it is possible to easily transfer a checkpoint and thus enabling container migration in Podman. With the following steps it is possible to migrate a running container from one system (source) to another (destination). Source system: * podman container checkpoint -l -e /tmp/checkpoint.tar.gz * scp /tmp/checkpoint.tar.gz destination:/tmp Destination system: * podman pull 'container-image-as-on-source-system' * podman container restore -i /tmp/checkpoint.tar.gz The exported tar.gz file contains the checkpoint image as created by CRIU and a few additional JSON files describing the state of the checkpointed container. Now the container is running on the destination system with the same state just as during checkpointing. If the container is kept running on the source system with the checkpoint flag '-R', the result will be that the same container is running on two different hosts.
