Are docker images portable across different linux flavours? Let's say, if I have OEL based docker image with database installed in it, can I run this in boot2docker on a Mac?
回答1:
Yes, you can archive an image (docker save/docker load), copy it on your mac unless your image and run a container in a boot2docker Tiny Core VM.
The only case where an image might not be portable is if its OS filesystem depends on certain patch level of the kernel.
In that case, a container from that image would only run on the right kernel.
hek2mgl mentions in the comments that a feature like inotify works only on Linux (should work on the TinyCore VM of boot2docker), but would not work when sharing a folder from the (non-Linux) host (ticket VBox 10660 or boot2docker PR 284 comment).
