防止在docker运行时创建卷

Question

Dockerfile can contain VOLUME /path instruction. That means that when docker run is executed, docker creates automatically a volume and binds it to /path inside container.

I'd like to skip the automatic volume creation in some cases. Is that possible somehow?

Answer 1

Not once it's be added to the Dockerfile. I'd personally avoid doing volumes inside of the Dockerfile since it ends up creating anonymous volumes as you've seen, but also because it breaks attempts to modify that directory in child images or even later steps inside of the same Dockerfile.
