* 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>
* Cross-reference *.rst files tooEd Santiago2020-08-11
| | | | | | | | | | | | | | | | | | | There are a bunch of *.rst files in docs/source, linking sometimes to man pages and sometimes to other .rst files. These files each have entries of the following form: :doc:`foo <link-to-foo>` Description of foo ...for all podman sub and sub-subcommands 'foo'. Read all .rst files and make sure that: - all entries in a given file are in alphabetical order - all link-to-foo targets point to existing doc files - every subcommand known by 'podman help' has a corresponding doc entry in a .rst file Signed-off-by: Ed Santiago <santiago@redhat.com>
* Add missing pages for docs.podman.ioDaniel J Walsh2020-08-10

* Update document formatting and packaging codeJhon Honce2019-10-31
| | | | | | | | | * Refactored code and Makefile to support new docs layout * Removed some old code packaging code * Add Readme.md to document what we're doing Signed-off-by: Jhon Honce <jhonce@redhat.com> Signed-off-by: baude <bbaude@redhat.com>
* Restructure documentation dirbaude2019-10-31
Restructuring the docs dir to make integration with sphinx easier. man pages now exist in docs/source/man and the sphinx make files exists in docs. Signed-off-by: baude <bbaude@redhat.com>
