Linux Docker installation and use tutorial

Docker is an open source engine that makes it easy to create a lightweight, portable, self-contained container for any application.

Containers that developers compile and test on their laptops can be deployed in bulk in production environments, including VMs(virtual machine), bare metal, OpenStack clusters, and other basic application platforms.

Docker source code is all written in Go language.

1. Basic environment

1. Role, ip, version, kernel

serverA 10.1.10.236 3.16.0-4-amd64 8.1 docket
docket 1.6.2

2. Install docter

1. Add sources

echo "deb http://http.debian.net/debian jessie-backports main" > > /etc/apt/sources.list

2. Update the source

apt-get update

3. Install the docker.io package

apt-get install docker.io

4. View the version

docker --version
Docker version 1.6.2, build 7c8fca2

5. Start the service

/etc/init.d/docker start
[ ok ] Starting docker (via systemctl): docker.service.

6. Pull debian and CentOS images

1) pull debian image

docker pull debian
latest: Pulling from debian
843e2bded498: Pull complete 
8c00acfb0175: Pull complete 
debian:latest: The image you are pulling has been verified. Important: image verification is a tech preview feature and should not be relied on to provide security.
Digest: sha256:d9168a2c1889b4c9d44952a23065c29b0656237909d618328275f42065602354
Status: Downloaded newer image for debian:latest

2) pull the centos image

docker pull centos
Pulling repository centos
0f73ae75014f: Download complete 
47d44cb6f252: Download complete 
f6f39725d938: Download complete 
f9a8cbc8dd13: Download complete 
f37e6a610a37: Download complete 
Status: Downloaded newer image for centos:latest

7. View the mirror

docker images
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
debian latest 8c00acfb0175 3 weeks ago 125.2 MB
centos latest 0f73ae75014f 3 weeks ago 172.3 MB

8. Run the container (virtual) named debian image

docker images
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
debian latest 8c00acfb0175 3 weeks ago 125.2 MB
centos latest 0f73ae75014f 3 weeks ago 172.3 MB

Produce one debian system)

1) run the debian mirrored container

docker run -i -t debian

2) view the version

root@10.1.10.236:~# docker run debian cat /etc/debian_version
8.2

3) view IP(it is dhcp that gets one at a time)

root@10.1.10.236:~# docker run debian ip 
a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default 
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host 
valid_lft forever preferred_lft forever
24: eth0: <NO-CARRIER,BROADCAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state DOWN group default 
link/ether 02:42:ac:11:00:0b brd ff:ff:ff:ff:ff:ff
inet 172.17.0.11/16 scope global eth0
valid_lft forever preferred_lft forever
inet6 fe80::42:acff:fe11:b/64 scope link tentative 
valid_lft forever preferred_lft forever

4) look at the kernel

docker --version
Docker version 1.6.2, build 7c8fca2

0

5) check hard disk partitioning

docker --version
Docker version 1.6.2, build 7c8fca2

9. Run the container named centos mirror (make a virtual centos system)

1) run the centos mirrored container

docker --version
Docker version 1.6.2, build 7c8fca2

2

2) view the version

root@10.1.10.236:~# docker run centos cat /etc/RedHat-release
CentOS Linux release 7.1.1503 (Core)

3) look at the kernel

docker --version
Docker version 1.6.2, build 7c8fca2

4

4) check ip

docker --version
Docker version 1.6.2, build 7c8fca2

5

5) check hard disk partitioning

docker --version
Docker version 1.6.2, build 7c8fca2
