Docker image layer update

(Raoxuanxuan) #1

I have a question about docker image.
Suppose image A has 3 layers and it has been packaged in other images, e.g. image B, C…
after some days, I found there is a bug in first layer and I fix it.
but how can I update image B, C…?
should I re-build image B,C … and re-run container of B, C…
If I don’t known how many images packaged this bug layer, what can I do?
