Golang to use Podman REST API
Hi all I am looking for some code examples in Golang to use Podman REST API. Is there a repository or some code examples that i can refer to? Also while looking at the Podman REST API. (https://docs.podman.io/en/latest/_static/api.html). how do i call the "podman run" using the REST API ? Regards Niranjan.

A container run boils down to create+start. Some examples can be found in how the remote client of Podman is using the Go-bindings for the REST API, for example: https://github.com/containers/podman/blob/main/pkg/domain/infra/tunnel/conta... The bindings live in pkg/bindings/{containers,images,...}. Kind regards, Valentin

When using the above bindings, I am getting below error: <snip> # pkg-config --cflags -- devmapper Package devmapper was not found in the pkg-config search path.

Add the following tags to your `go build`: -tags "exclude_graphdriver_devicemapper exclude_graphdriver_btrfs" That will exclude the two graph drivers from the build. Ideally the drivers should not be needed at all but I assume that *some* transitive dependency of the bindings are pulling them into the build. Kind regards, Valentin
