How to update deployment's initContainer image without down time in kubernetes?

kubernetes version:1.10.4

In my project,I have an initContainer image and an common container image,I want to update the initContainer's image with zero down time.

But the kubectl set image xxx command cannot work on initContainer.

I have read the document about rolling update containers' image, but not found the information about initContainer image.

Who has encountered this situation?

If you want to do manual change I'd start with 

kubectl edit deployment xxx

for non-interactive operations it's probably easiest to use kubectl patch like 

kubectl patch deployment/xxx -p '{"spec": {"template": {"spec": {"initContainers":[{"name":"cinit", "image":"alpine:3.6"}]}}}}'
