* [CI:DOCS] refine the runlabel man pageValentin Rothberg2021-07-20
| | | | | | | | | | | | * Write a description to outline the scope and mechanism of runlabel. * Describe the variables/attributes that we want to be used. * Do not describe the --optN or OPTN flags/variables since they are already hidden flags and date back to the Atomic days. * Update references to other man pages. * Remove unsupported variables (e.g., SUDO_*) which caused confusion.

* podman diff accept two images or containersPaul Holzinger2021-07-02
| | | | | | | | | | | | | | | | | | | First, make podman diff accept optionally a second argument. This allows the user to specify a second image/container to compare the first with. If it is not set the parent layer will be used as before. Second, podman container diff should only use containers and podman image diff should only use images. Previously, podman container diff would use the image when both an image and container with this name exists. To make this work two new parameters have been added to the api. If they are not used the previous behaviour is used. The same applies to the bindings. Fixes #10649 Signed-off-by: Paul Holzinger <pholzing@redhat.com>
* Initial implementation of renaming containersMatthew Heon2021-01-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Basic theory: We remove the container, but *only from the DB*. We leave it in c/storage, we leave the lock allocated, we leave it running (if it is). Then we create an identical container with an altered name, and add that back to the database. Theoretically we now have a renamed container. The advantage of this approach is that it doesn't just apply to rename - we can use this to make *any* configuration change to a container that does not alter its container ID. Potential problems are numerous. This process is *THOROUGHLY* non-atomic at present - if you `kill -9` Podman mid-rename things will be in a bad place, for example. Also, we can't rename containers that can't be removed normally - IE, containers with dependencies (pod infra containers, for example). The largest potential improvement will be to move the majority of the work into the DB, with a `RecreateContainer()` method - that will add atomicity, and let us remove the container without worrying about depencies and similar issues. Potential problems: long-running processes that edit the DB and may have an older version of the configuration around. Most notable example is `podman run --rm` - the removal command needed to be manually edited to avoid this one. This begins to get at the heart of me not wanting to do this in the first place... This provides CLI and API implementations for frontend, but no tunnel implementation. It will be added in a future release (just held back for time now - we need this in 3.0 and are running low on time). This is honestly kind of horrifying, but I think it will work.

* Add podman container ps commandPaul Holzinger2020-11-23
| | | | | | | | | This command exists in docker and is also in our documentation. Also remove mentions of `podman ls` or `podman list`. These commands do not exists in podman or docker. Signed-off-by: Paul Holzinger <paul.holzinger@web.de>
* Cleanup handling of podman mount/unmountDaniel J Walsh2020-07-27
| | | | | | | | | | | We should default to the user name unmount rather then the internal name of umount. Also User namespace was not being handled correctly. We want to inform the user that if they do a mount when in rootless mode that they have to be first in the podman unshare state. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>
