* InfraContainer Reworkcdoern2021-08-26
| | | | | | | | | | InfraContainer should go through the same creation process as regular containers. This change was from the cmd level down, involving new container CLI opts and specgen creating functions. What now happens is that both container and pod cli options are populated in cmd and used to create a podSpecgen and a containerSpecgen. The process then goes as follows FillOutSpecGen (infra) -> MapSpec (podOpts -> infraOpts) -> PodCreate -> MakePod -> createPodOptions -> NewPod -> CompleteSpec (infra) -> MakeContainer -> NewContainer -> newContainer -> AddInfra (to pod state) Signed-off-by: cdoern <cdoern@redhat.com>
* Network interfacePaul Holzinger2021-08-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement a new network interface to abstract CNI from libpod. The interface is implemented for the CNI backend but in the future we can add more backends. The code is structured in three new packages: - `libpod/network/types`: contains the interface definition and the necessary types for it. - `libpod/network/cni` contains the interface implementation for the CNI backend. - `libpod/network/util` a set of utility functions related to networking. The CNI package uses ginkgo style unit tests. To test Setup/Teardown the test must be run as root. Each test will run in their own namespace to make the test independent from the host environment. New features with the CNI backend: - The default network will be created in memory if it does not exists on disk. - It can set more than one static IP per container network. - Networks are loaded once from disk and only if this interface is used, e.g. for commands such as `podman info` networks are not loaded. This reduces unnecessary disk IO. This commit only adds the interface it is not wired into libpod. This requires a lot of breaking changes which will be done in a followup commit. Once this is integrated into libpod the current network code under `libpod/network` should be removed. Also the dependency on OCICNI should be dropped.

* Allow changing of port forward rules on restoreAdrian Reber2021-06-04
| | | | | | | | | | | | | | | | | | | | Restored containers, until now, had the same port mappings as the original started container. This commit adds the parameter '--publish' to 'podman container restore' with the same semantic as during create/run. With this change it is possible to create a copy from a container with a '--publish' rule and replace the original '--publish' setting with a new one. # podman run -p 2345:8080 container # podman container checkpoint -l --export=dump.tar # podman container restore -p 5432:8080 --import=dump.tar The restored container will now listen on localhost:5432 instead of localhost:2345 as the original created container.

* Ports given only by number should have random host portMatthew Heon2020-10-08
| | | | | | | | | | | | | | | In Podman 1.9.3, `podman run -p 80` would assign port 80 in the container to a random port on the host. In Podman 2.0 and up, it assigned Port 80 in the container to Port 80 on the host. This is an easy fix, fortunately - just need to remove the bit that assumed host port, if not given, should be set to container port. We also had a test for the bad behavior, so fix it to test for the correct way of doing things. Fixes #7947 Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* Do not set host IP on ports when 0.0.0.0 requestedMatthew Heon2020-08-03
| | | | | | | | | | | | | | | | Docker and CNI have very different ideas of what 0.0.0.0 means. Docker takes it to be 0.0.0.0/0 - that is, bind to every IPv4 address on the host. CNI (and, thus, root Podman) take it to mean the literal IP 0.0.0.0. Instead, CNI interprets the empty string ("") as "bind to all IPs". We could ask CNI to change, but given this is established behavior, that's unlikely. Instead, let's just catch 0.0.0.0 and turn it into "" when we parse ports.

* 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.

* | Enable IPv6 port bindingMatthew Heon2020-06-10
|/ | | | | | | | | | | | | | | | | | | | | | | | Two areas needed tweaking to accomplish this: port parsing and binding ports on the host. Parsing is an obvious problem - we have to accomodate an IPv6 address enclosed by [] as well as a normal IPv4 address. It was slightly complicated by the fact that we previously just counted the number of colons in the whole port definition (a thousand curses on whoever in the IPv6 standard body decided to reuse colons for address separators), but did not end up being that bad. Libpod also (optionally) binds ports on the host to prevent their reuse by host processes. This code was IPv4 only for TCP, and bound to both for UDP (which I'm fairly certain is not correct, and has been adjusted). This just needed protocols adjusted to read "tcp4"/"tcp6" and "udp4"/"udp6" based on what we wanted to bind to. Fixes #5715 Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* 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.
