When using the above bindings, I am getting below error:

# pkg-config --cflags -- devmapper
Package devmapper was not found in the pkg-config search path.
Perhaps you should add the directory containing `devmapper.pc'
to the PKG_CONFIG_PATH environment variable
Package 'devmapper', required by 'virtual:world', not found
pkg-config: exit status 1

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,

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 ?
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/co...
The bindings live in pkg/bindings/{containers,images,...}.
Kind regards,
Valentin

Niranjan.
