1、要先安裝docker-ce-selinux-17.03.2.ce,否則安裝docker-ce會報錯(僅阿里雲安裝docker前提)

yum install 

2、安裝依賴

3、設定docker源

$sudo yum-config-manager \

--add-repo \

4、啟動edge版 docker.repo源

$sudo yum-config-manager --enable docker-ce-edge

5、安裝docker-ce版

$sudo yum install docker-ce-17.03.2.ce

6、啟動docker

$sudo systemctl start docker

7、設定自動啟動

$systemctl enable docker

8、映象加速配置:

$sudo mkdir -p /etc/docker

$sudo tee /etc/docker/daemon.json <<-'eof'

eofsudo systemctl daemon-reload

sudo systemctl restart docker

9、驗證:執行hello-world

$docker run hello-world

補充:調整docker0的網段方式:

sudo systemctl stop docker

通過命令route -n

檢視docker0是否存在,若存在需先刪除:

sudo ip link del docker0

vi /etc/docker/daemon.json 新增內容 "bip": "ip/netmask" [ 切勿與宿主機同網段 ]

如:docker日誌/垃圾檔案清理:

1、執行docker命令:docker system prune

2、清理日誌:

#!/bin/sh

echo "******************** start clean docker containers logs *************************="

logs=$(find /var/lib/docker/containers/ -name *-json.log)

for log in $logs

doecho "clean logs : $log"

cat /dev/null > $log

done

echo "******************** end clean docker containers logs   *************************="

docker rm -f -v $(docker ps -aq)

docker volume rm $(docker volume ls)

rm -rf /var/lib/etcd/

docker配置

vi /etc/docker/daemon.sjon

"bip":"172.21.100.1/24"

,"insecure-registries":["172.16.101.43:5000","172.16.101.49","docker.jieyue.com"]

,"registry-mirrors": ["","",""]

,"log-driver": "json-file"

,"log-opts":

,"max-concurrent-downloads": 10

,"max-concurrent-uploads": 10

,"storage-driver": "overlay2"

,"storage-opts": ["overlay2.override_kernel_check=true"]

}
