Docker環境準備

基礎環境

Centos7+git

確認git忽略ssl證書校驗

su
echo 'export GIT_SSL_NO_VERIFY=true' >>/etc/bashrc

添加第三方源

只追加大型第三方源 EPEL 源

sudo yum install epel-release

升級系統

升級的Centos7.2

sudo yum update
sudo yum upgrade

docker環境

安裝docker並設置爲開機自動啓動

sudo yum  install docker
sudo chkconfig docker on

利用國內的daocloud.io爲docker加速，見相關文檔https://www.daocloud.io/mirror#accelerator-doc

curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://db9bd5cd.m.daocloud.io

在daocloud.io上創建本身的帳號，將主機資源加入到daocloud.io中集中管理

su
curl -sSL https://get.daocloud.io/daomonit/install.sh | sh -s e66d49d38c29b6015c7378c08ed8f3ec193c0931

重啓系統

sudo reboot

查看docker服務

[root@localhost zookeeper]# service docker status -l

安裝docker-compose

參考官方文檔https://docs.docker.com/compose/install/ ，安裝docker compose並配置執行權限

su
curl -L https://github.com/docker/compose/releases/download/1.8.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

測試安裝狀況

$ docker-compose --version
docker-compose version 1.8.0, build f3628c7
