can add build method from spec?

build_with_spec(spec)

Hey, can you add more details regarding where you want this method, and probably an example usage? Thanks.

[Jino]

develop a command line tool that runs independently and does not need to be used with a container runtime. spec can be customized and passed to build

 pub fn build_with_spec(self,mut spec: Spec) -> Result<Container, LibcontainerError> 

usage:

let mut spec = oci_spec::runtime::Spec::default();    //init spec
spec.set_hostname(Some("haha".to_owned()));  //config spec
...

.build_with_spec(sepc) //use build_with_spec

You can write the created spec into the config.json file in bundle dir, and the ContainerBuilder will load it from there. Would that not work for you?

[Jino]

config.json file requires additional maintenance. in a single command line tool, configuring the Spec through code can be more lightweight and customized.

libcontainer is a library, don’t limit it to container runtime only.
