API / GO container creation on cluster member

I can’t find a way to create a container on a specific member of the cluster.

I’ve tried to connect directly to a member of the cluster :

     c, err := lxd.ConnectLXD("https://1.2.3.4:8443", &CustomConnectionArgs)
        req := api.ContainersPost{
                Name: ctname,
                Source: api.ContainerSource{
                Type:  "image",
                Alias: imgname,
                },
        }
        op, err := c.CreateContainer(req)

but somehow the container is always created on my first cluster member.
Am I missing something ?

c.UseTarget("name of node").CreateContainer

Can’t believe I didn’t see it.
Thanks
