Almost enough.

But may we had !encapsulation and portability ?

@c9s

That's awesome!

That's awesome!

But may it be more lightweight?

Maybe you can try to use DOCKER!

How docker can help us?


Built specify environment for target project.

Run and List container

$ docker run ubuntu:trusty /bin/echo "hello, world"hello, world

The container is finished, so we use -a

Run and list running container

docker run ubuntu:latest /bin/sh -c \"while true; do echo hello, world; sleep 1; done;"

hello, worldhello, world……
