* Improvements for machinebaude2021-03-25
| | | | | | clean up ci failures and add appropriate arch,os exclusion tags Signed-off-by: baude <bbaude@redhat.com>
* introduce podman machinebaude2021-03-25
| | | | | | | | | | | | | | | podman machine allows podman to create, manage, and interact with a vm running some form of linux (default is fcos). podman is then configured to be able to interact with the vm automatically. while this is usable on linux, the real push is to get this working on both current apple architectures in macos. Ashley Cui contributed to this PR and was a great help. [NO TESTS NEEDED] Signed-off-by: baude <bbaude@redhat.com>
* bump go module to v3Valentin Rothberg2021-02-22
| | | | | | | | | We missed bumping the go module, so let's do it now :) * Automated go code with github.com/sirkon/go-imports-rename * Manually via `vgrep podman/v2` the rest Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
* Correct port range logic for port generationMatthew Heon2020-12-08
| | | | | | | | | | | | | The existing logic (Range > 0) always triggered, because range is guaranteed to be at least 1 (a single port has a range of 1, a two port range (e.g. 80-81) has a range of 2, and so on). As such this could cause ports that had a host port assigned to them by the user to randomly assign one instead. Fixes #8650 Fixes #8651 Signed-off-by: Matthew Heon <mheon@redhat.com>
* Fix host to container port mapping for simple rangesSascha Grunert2020-10-19
| | | | | | | | | | | | | | | | | This fixes the issue that a simple port range should map to a random port range from the host to the container, if no host port range is specified. For example this fails without applying the patch: ``` > podman run -it -p 6000-6066 alpine Error: cannot listen on the TCP port: listen tcp4 :53: bind: address already in use ``` The issue is that only the first port is randomly chosen and all following in the range start by 0 and increment. This is now fixed by tracking the ranges and then incrementing the random port if necessary. Signed-off-by: Sascha Grunert <sgrunert@suse.com>
* Binding the same container port to >1 host port is OKMatthew Heon2020-07-29
| | | | | | | | | | | The initial version of the new port code mistakenly restricted this, so un-restrict it. We still need to maintain the map of container ports, unfortunately (need to verify if the port in question is a duplicate, for example). Fixes #7062 Signed-off-by: Matthew Heon <matthew.heon@pm.me>

* Fix "Error: unrecognized protocol \"TCP\" in port mapping"Akihiro Suda2020-07-15
| | | | | | | | "TCP" in upper characters was not recognized as a valid protocol name. Fix #6948 Signed-off-by: Akihiro Suda <akihiro.suda.cz@hco.ntt.co.jp>
* move go module to v2Valentin Rothberg2020-07-06
| | | | | | | | | | | | | | | With the advent of Podman 2.0.0 we crossed the magical barrier of go modules. While we were able to continue importing all packages inside of the project, the project could not be vendored anymore from the outside. Move the go module to new major version and change all imports to `github.com/containers/libpod/v2`. The renaming of the imports was done via `gomove` [1].

* Allow empty host port in --publish flagMatthew Heon2020-06-29
| | | | | | | | | | | | | | | | | I didn't believe that this was actually legal, but it looks like it is. And, unlike our previous understanding (host port being empty means just use container port), empty host port actually carries the same meaning as `--expose` + `--publish-all` (that is, assign a random host port to the given container port). This requires a significant rework of our port handling code to handle this new case. I don't foresee this being commonly used, so I optimized having a fixed port number as fast path, which this random assignment code running after the main port handling code only if necessary.

* Rework port parsing to support --expose and -PMatthew Heon2020-05-04
As part of this, make a major change to the type we use to represent port mappings in SpecGen (from using existing OCICNI structs to using our own custom one). This struct has the advantage of supporting ranges, massively reducing traffic over the wire for Podman commands using them (for example, the `podman run -p 5000-6000` command will now send only one struct instead of 1000). This struct also allows us to easily validate which ports are in use, and which are not, which is necessary for --expose. Once we have parsed the ports from the new struct, we can produce an accurate map including all currently requested ports, and use that to determine what ports need to be exposed (some requested exposed ports may already be included in a mapping from --publish and will be ignored) and what open ports on the host we can map them to.
