podman container clone takes the id of an existing continer and creates a specgen from the given container's config recreating all proper namespaces and overriding spec options like resource limits and the container name if given in the cli options this command utilizes the common function DefineCreateFlags meaning that we can funnel as many create options as we want into clone over time allowing the user to clone with as much or as little of the original config as they want. container clone takes a second argument which is a new name and a third argument which is an image name to use instead of the original container's the current supported flags are: --destroy (remove the original container) --name (new ctr name) --cpus (sets cpu period and quota) --cpuset-cpus --cpu-period --cpu-rt-period --cpu-rt-runtime --cpu-shares --cpuset-mems --memory --run resolves #10875 Signed-off-by: cdoern <cdoern@redhat.com> Signed-off-by: cdoern <cbdoer23@g.holycross.edu> Signed-off-by: cdoern <cdoern@redhat.com>
