Docker是一個開源的引擎，可以輕松的為任何應(yīng)用創(chuàng)建一個輕量級的、可移植的、自給自足的容器。
開發(fā)者在筆記本上編譯測試通過的容器可以批量地在生產(chǎn)環(huán)境中部署，包括VMs(虛擬機(jī))、bare metal、OpenStack集群和其他的基礎(chǔ)應(yīng)用平臺。
Docker的源代碼全部是用Go語言寫的。
一、基礎(chǔ)環(huán)境
1、角色、ip、版本、內(nèi)核
serverA 10.1.10.236 3.16.0-4-amd64 8.1 docket
docket 1.6.2
二、安裝docter
1、添加源
echo "deb http://http.debian.net/debian jessie-backports main" >> /etc/apt/sources.list
2、更新源
apt-get update
3、安裝docker.io包
apt-get install docker.ioReading package lists... DoneBuilding dependency tree Reading state information... DoneThe following extra packages will be installed:aufs-tools cgroupfs-mount git git-man libapparmor1 liberror-perl libnih-dbus1 libnih1 makedev mountall plymouthSuggested packages:btrfs-tools debootstrap lxc rinse git-daemon-run git-daemon-sysvinit git-doc git-el git-email git-gui gitk gitweb git-arch git-cvs git-mediawiki git-svn desktop-baseplymouth-themesThe following NEW packages will be installed:aufs-tools cgroupfs-mount docker.io git git-man libapparmor1 liberror-perl libnih-dbus1 libnih1 makedev mountall plymouth0 upgraded, 12 newly installed, 0 to remove and 54 not upgraded.Need to get 9,986 kB of archives.After this operation, 47.2 MB of additional disk space will be used.Do you want to continue? [Y/n]
4、查看版本
docker --versionDocker version 1.6.2, build 7c8fca2
5、啟動服務(wù)
/etc/init.d/docker start[ ok ] Starting docker (via systemctl): docker.service.
6、拉取debian和CentOS鏡像
1)拉取debian鏡像
docker pull debianlatest: Pulling from debian843e2bded498: 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:d9168a2c1889b4c9d44952a23065c29b0656237909d618328275f42065602354Status: Downloaded newer image for debian:latest
2)拉取centos鏡像
docker pull centosPulling repository centos0f73ae75014f: Download complete 47d44cb6f252: Download complete f6f39725d938: Download complete f9a8cbc8dd13: Download complete f37e6a610a37: Download complete Status: Downloaded newer image for centos:latest
7、查看鏡像
docker imagesREPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZEdebian latest 8c00acfb0175 3 weeks ago 125.2 MBcentos latest 0f73ae75014f 3 weeks ago 172.3 MB
8、運行名為debian鏡像的容器(虛擬
docker imagesREPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZEdebian latest 8c00acfb0175 3 weeks ago 125.2 MBcentos latest 0f73ae75014f 3 weeks ago 172.3 MB
出1個debian系統(tǒng))
1)運行debian鏡像的容器
docker run -i -t debian
2)查看版本
root@10.1.10.236:~# docker run debian cat /etc/debian_version8.2
3)查看IP(是dhcp獲得 每次獲得都不一樣)
root@10.1.10.236:~# docker run debian ip a1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00inet 127.0.0.1/8 scope host lovalid_lft forever preferred_lft foreverinet6 ::1/128 scope host valid_lft forever preferred_lft forever24: 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:ffinet 172.17.0.11/16 scope global eth0valid_lft forever preferred_lft foreverinet6 fe80::42:acff:fe11:b/64 scope link tentative valid_lft forever preferred_lft forever
4)查看內(nèi)核
root@10.1.10.236:~# docker run debian uname -r3.16.0-4-amd64
5)查看硬盤分區(qū)情況
root@10.1.10.236:~# docker run -i -t debian df -ThFilesystem Type Size Used Avail Use% Mounted onnone aufs 9.1G 1.6G 7.1G 18% /tmpfs tmpfs 115M 0 115M 0% /devshm tmpfs 64M 0 64M 0% /dev/shm/dev/sda1 ext4 9.1G 1.6G 7.1G 18% /etc/hosts
9、運行名為centos鏡像的容器(虛擬出1個centos系統(tǒng))
1)運行centos鏡像的容器
docker run -i -t centos
2)查看版本
root@10.1.10.236:~# docker run centos cat /etc/RedHat-releaseCentOS Linux release 7.1.1503 (Core)
3)查看內(nèi)核
root@10.1.10.236:~# docker run centos uname -r3.16.0-4-amd64
4)查看ip
root@10.1.10.236:~# docker run centos ip a1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00inet 127.0.0.1/8 scope host lovalid_lft forever preferred_lft foreverinet6 ::1/128 scope host valid_lft forever preferred_lft forever46: eth0: <NO-CARRIER,BROADCAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state DOWN link/ether 02:42:ac:11:00:16 brd ff:ff:ff:ff:ff:ffinet 172.17.0.22/16 scope global eth0valid_lft forever preferred_lft foreverinet6 fe80::42:acff:fe11:16/64 scope link tentative valid_lft forever preferred_lft forever
5)查看硬盤分區(qū)情況
root@10.1.10.236:~# docker run centos df -ThFilesystem Type Size Used Avail Use% Mounted onrootfs rootfs 9.1G 1.6G 7.1G 18% /none aufs 9.1G 1.6G 7.1G 18% /tmpfs tmpfs 115M 0 115M 0% /devshm tmpfs 64M 0 64M 0% /dev/shm/dev/sda1 ext4 9.1G 1.6G 7.1G 18% /etc/hoststmpfs tmpfs 115M 0 115M 0% /proc/kcoretmpfs tmpfs 115M 0 115M 0% /proc/timer_stats
