1. Introduction
This post shows how to install "Docker" on a CentOS 6.x system.2. Step-by-Step
2.1. Check if processosr suports Docker
- Docker does not support 32 bits processors
- Docker is supported by Kernel 3.8 or higher
[root@localhost install-docker]# uname -a
Linux localhost.localdomain 2.6.32-358.el6.x86_64 #1 SMP Fri Feb 22 00:31:26 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
[root@localhost install-docker]#
2.2. Install Docker using official scripts from official
[root@localhost ~]# mkdir install-docker[root@localhost ~]# cd install-docker/
[root@localhost install-docker]# wget -qO- https://get.docker.com | sh
+ sh -c 'sleep 3; yum -y -q install docker-engine'
warning: rpmts_HdrFromFdno: Header V4 RSA/SHA1 Signature, key ID 2c52609d: NOKEY
Importing GPG key 0x2C52609D:
Userid: "Docker Release Tool (releasedocker) <docker@docker.com>"
From : https://yum.dockerproject.org/gpg
If you would like to use Docker as a non-root user, you should now consider
adding your user to the "docker" group with something like:
sudo usermod -aG docker your-user
Remember that you will have to log out and back in for this to take effect!
[root@localhost install-docker]#
2.3. Start Docker service and configure to startup
[root@localhost install-docker]# service docker status
docker is stopped
[root@localhost install-docker]# service docker start
Starting cgconfig service: [ OK ]
Starting docker: [ OK ]
[root@localhost install-docker]# chkconfig docker
2.4. Using Docker basic commands
- Docker version
Docker version 1.7.1, build 786b29d
- Is there any container running? And what about created containger but not running?
[root@localhost install-docker]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
[root@localhost install-docker]# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
[root@localhost install-docker]#
- Searching images from containers of 'centos' and 'debian'

- My first containers
Run ( launch ) your 'debian' container, and at first update your SO (this may takes a while on first time you run this image), check your IP, and exit or loggof or ctrl+d. Notice that when you exit container, this does not exist anymore!!!
