###
### Hello from Docker!
### This message shows that your installation appears to be working correctly.
###
### To generate this message, Docker took the following steps:
### 1. The Docker client contacted the Docker daemon.
### 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
### (amd64)
### 3. The Docker daemon created a new container from that image which runs the
### executable that produces the output you are currently reading.
### 4. The Docker daemon streamed that output to the Docker client, which sent it
### to your terminal.
###
### To try something more ambitious, you can run an Ubuntu container with:
### $ docker run -it ubuntu bash
###
### Share images, automate workflows, and more with a free Docker ID:
### https://hub.docker.com/
###
