版本信息:

[root@localhost]#? cat /proc/version

Linux version 3.10.0-514.el7.x86_64 (builder@kbuilder.dev.centos.org) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-11) (GCC) ) #1 SMP Tue Nov 22 16:42:41 UTC 2016

[root@localhost jenkins]# cat? /etc/redhat-release

CentOS Linux release 7.3.1611 (Core)

?

# Centos系統是離線的,但是可以通過代理訪問網絡,否則,就無法pull Image了.

# 查看yum list中是否有docker安裝包:

[root@localhost home]# yum list | grep docker

docker.x86_64????????????????????????????? 2:1.12.6-32.git88a4867.el7.centos

docker-client.x86_64?????????????????????? 2:1.12.6-32.git88a4867.el7.centos

docker-common.x86_64?????????????????????? 2:1.12.6-32.git88a4867.el7.centos

…

[root@localhost home]#

2安裝Docker

# install

sudo yum install -y docker.x86_64

#? yum install docker

?

# 查看docker是否安裝成功

docker --version

?

# 開機自啟動, 好像開機啟動并不是很靈

sudo chkconfig docker on

# 查看docker daemon是否在運行

ps aux | grep docker

3設置代理

# following link is to resolve docker-runc not found issue,proxy is not necessary *#

ln -s /usr/libexec/docker/docker-proxy-current /usr/bin/docker-proxy

ln -s /usr/libexec/docker/docker-runc-current /usr/bin/docker-runc

?

#停止docker service(設置代理前,需要停止)

service docker stop

?

# 設置代理, 成功后,會自動啟動docker service

sudo HTTP_PROXY=http://ip:port /usr/bin/dockerd --userland-proxy=false &

4 Docker Service

# 啟動Docker Service

# 注: 設置代理時,Docker Service會自動啟動

service docker start

# 或者這種啟動方式

systemctl start docker.service

?

#停止docker service(設置代理前,需要停止)

service docker stop

# 或者這種停止方式

systemctl stop docker.service

?

# 查看服務狀態

systemctl status docker.service

?

# 查看docker daemon是否在運行

ps aux | grep docker

?

?

5 Image

# 下載Image,? 默認從docker.io下載,速度會比較慢

#?????????? 可以從daocloud.io中下載,速度會快一些.

# 我在公司, Centos上感覺不明顯, 在家里用ubuntu感覺特別明顯

docker pull centos

?

# 查詢倉庫中的Image

# --automated=false:?????? 僅顯示自動創建的鏡像

# --no-trunc=false:?? 不截斷顯示

# -s, --starts=0:??????? 指定星級以上

docker search -s 10 centos

?

# 查詢本地Image

docker images

?

# 刪除Image

?docker rmi docker.io/Ubuntu

6 運行Image

# 運行Image

?# 注意: 運行Image時, 需要關閉代理,重啟docker service,

?#????? 否則會遇到錯誤:container_linux.go:247: starting container process caused

?#????? "process_linux.go:334: running prestart hook 1 caused \"error running hook: exit status 1, stdout: , stderr: \""

#????????? /usr/bin/docker-current: Error response from daemon: invalid header field value "oci runtime error:

#????????? container_linux.go:247: starting container process caused \"process_linux.go:334:

#?????????? running prestart hook 1 caused \\\"error running hook: exit status 1, stdout: , stderr: \\\"\"\n".

?

# 方式1

sudo docker? run centos /bin/echo 'Hello World'

# 帶調試信息

sudo docker --debug=true run centos /bin/echo 'Hello World'

?

?

#方式2

[root@localhost home]# docker create centos

3e8185a9fb586e1b3f12fb1c69c2a22225df1e5505c9315e3b62743d489d2904

?

# 查看容器信息

[root@localhost home]# docker ps -a

CONTAINER ID??????? IMAGE?????????????? COMMAND???????????? CREATED???????????? STATUS????????????? PORTS?????????????? NAMES

3e8185a9fb58??????? centos????????????? "/bin/bash"???????? 5 seconds ago?????? Created???????????????????????????????? gigantic_franklin

[root@localhost home]# docker start 3e8185a9fb58

?

docker run -idt --name pcta-demon matthewx:pcta-matthewx

?

# 進入容器

docker attach pcta-demon

?

# 刪除容器

docker rm 3e8185a9fb58

?

7 卸載Docker

#centos卸載

yum list installed | grep docker

yum -y remove docker.x86_64?

yum -y remove docker-client.x86_64?

yum -y remove docker-common.x86_64?

# 如果/var/lib/docker刪除失敗,

# 請使用lsof |grep docker看看有哪些進程在使用,kill掉這些進程.

# 此處刪除應該是刪除pull的image等,所以也可以不刪除.

rm -rf /var/lib/docker

lsof |grep docker
