| | | | | | | | | | | | | | | | | | | | All of our filters worked exclusive resulting in `--filter status=created --filter status=exited` to return nothing.

* / Improve the shell completion apiPaul Holzinger2020-11-16
|/ | | | | | | | | | | | | | | | | | | | One main advantage of the new shell completion logic is that we can easly parse flags and adjust based on the given flags the suggestions. For example some commands accept the `--latest` flag only if no arguments are given. This commit implements this logic in a simple maintainable way since it reuses the already existing `Args` function in the cmd struct. I also refactored the `getXXX` function to match based on the namei/id which could speed up the shell completion with many containers, images, etc... I also added the degraded status to the valid pod status filters which was implemented in #8081. Signed-off-by: Paul Holzinger <paul.holzinger@web.de>

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Convert the existing network aliases set/remove code to network connect and disconnect. We can no longer modify aliases for an existing network, but we can add and remove entire networks. As part of this, we need to add a new function to retrieve current aliases the container is connected to (we had a table for this as of the first aliases PR, but it was not externally exposed). At the same time, remove all deconflicting logic for aliases. Docker does absolutely no checks of this nature, and allows two containers to have the same aliases, aliases that conflict with container names, etc - it's just left to DNS to return all the IP addresses, and presumably we round-robin from there? Most tests for the existing code had to be removed because of this. Convert all uses of the old container config.Networks field, which previously included all networks in the container, to use the new DB table. This ensures we actually get an up-to-date list of in-use networks. Also, add network aliases to the output of `podman inspect`. Signed-off-by: Matthew Heon <matthew.heon@pm.me>

This Patch consolodates them to use container/storage version. This PR also fixes a failure mode when the homedir does not exists, and the user sets a root path. In this situation podman should continue to work. Podman does not require a users homedir to exist in order to run. Finally the rootlessConfigHomeDirOnce and rootlessRuntimeDirOnce were broken, because if an error ever happened, they would not be recorded the second time, and "" would be returned as the path.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the database backend for network aliases. Aliases are additional names for a container that are used with the CNI dnsname plugin - the container will be accessible by these names in addition to its name. Aliases are allowed to change over time as the container connects to and disconnects from networks. Aliases are implemented as another bucket in the database to register all aliases, plus two buckets for each container (one to hold connected CNI networks, a second to hold its aliases). The aliases are only unique per-network, to the global and per-container aliases buckets have a sub-bucket for each CNI network that has aliases, and the aliases are stored within that sub-bucket. Aliases are formatted as alias (key) to container ID (value) in both cases. Three DB functions are defined for aliases: retrieving current aliases for a given network, setting aliases for a given network, and removing all aliases for a given network.

The destination is the path inside the container. Image mounts further support an optional `rw,readwrite` parameter which if set to "true" will yield the mount writable inside the container. Note that no changes are propagated to the image mount on the host (which in any case is read only). Mounts are overlay mounts.
