Hello World
|
|
===========
|
|
|
|
.. include:: example_header.inc
|
|
|
|
This is the most basic example available for using Docker.
|
|
|
|
Download the base container
|
|
|
|
.. code-block:: bash
|
|
|
|
# Download a base image
|
|
docker pull base
|
|
|
|
The *base* image is a minimal *ubuntu* based container, alternatively you can select *busybox*, a bare
|
|
minimal linux system. The images are retrieved from the docker repository.
|
|
|
|
|
|
.. code-block:: bash
|
|
|
|
#run a simple echo command, that will echo hello world back to the console over standard out.
|
|
docker run base /bin/echo hello world
|
|
|
|
**Explanation:**
|
|
|
|
- **"docker run"** run a command in a new container
|
|
- **"base"** is the image we want to run the command inside of.
|
|
- **"/bin/echo"** is the command we want to run in the container
|
|
- **"hello world"** is the input for the echo command
