* Improve DESTDIR/PREFIX/ETCDIR handlingLawrence Chan2019-06-14
| | | | | | | | | | | - PREFIX is now passed saved in the binary at build-time so that default paths match installation paths. - ETCDIR is also overridable in a similar way. - DESTDIR is now applied on top of PREFIX for install/uninstall steps. Previously, a DESTDIR=/foo PREFIX=/bar make would install into /bar, rather than /foo/bar. Signed-off-by: Lawrence Chan <element103@gmail.com>
* Add --storage flag to 'podman rm' (local only)Matthew Heon2019-06-13
| | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | We were formerly dumping spec.Mount structs, with no care as to whether it was user-generated or not - a relic of the very early days when we didn't know whether a user made a mount or not. Now that we do, match our output to Docker's dedicated mount struct. 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.

| * | 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.

As a fallback if the join fails for any reason (e.g. the pause process was killed), then we try to join the running containers as we were doing before.
