Docker Run

When you are likely to run a container on your own machine, you need two steps.

  1. Find the image repository and a proper tag.
  2. Use docker run to set container runtime parameters and then start.

Example

We'd like to run a RabbitMQ on your local machine. First, we choose an image from the official repository. E.g. we choose rabbitmq:management-alpine. So we got the basic command:

$ docker run rabbitmq:management-alpine

To add port forwarding to the container, we need to specify the -p parameter:

$ docker run \
-p 5672:5672 \
-p 15672:15672 \
rabbitmq:management-alpine

It replace our host port 5672 and 15672 with the container's.

After that, we'd like to give a reasonable name to the container and ask the container auto start after my docker daemon is restarted. So I need to add command --name and --restart:

$ docker run \
-p 5672:5672 \
-p 15672:15672 \
--name dev-rabbitmq \
--restart always \
-d \
rabbitmq:management-alpine

And don't forget the -d if you don't want to attach the container STDIN/STDOUT.
