Building rabbitmq based on docker

The Docker system has two programs: the docker server and the docker client. The docker server is a service process that manages all the containers. The docker client acts as the remote controller of the docker server and can be used to control the server process of the docker. In most cases, the docker server and client run on the same machine.

1. Install docker and install yum directly in centos

# yum install-y docker

You can use docker version to view the installed version information. If you do not start docker, you can only see the version information of the client, and you can see the version information of the client and server after startup.

2. Image management

Docker images: lists all local mirrors

Docker search: find the image to install

Docker pull: download the image to install

Docker push: upload image

Docker rmi: deleting image

Here is an example of installing rabbitmq:

1. You can first use docker images to list all the images in the docker. Because it is a newly installed docker, the list is empty.

2. Find the rabbitmq image file

# docker search rabbitmq

3. Download rabbitmq image

To quickly download the image, create a daemon.json file with the following contents:

Mkdir-p / etc/docker

Tee / etc/docker/daemon.json
