docker daemon proxy 設定 on CentOS 6

1. 編輯 docker daemon 設定檔，設定 docker daemon 的 proxy
   

   # vim /etc/sysconfig/docker
   other_args=
   export HTTP_PROXY="http://<ip>:<port>"
   export HTTPS_PROXY="https://<ip>:<port>"

2. 重新啟動 docker daemon
   

   # service docker restart

3. 搜尋 coreos image
   

   # docker search coreos

Install Docker on CentOS 6.4

1. 安裝 EPEL repository repository
   

   #  wget http://mirror-fpt-telecom.fpt.net/fedora/epel/6/i386/epel-release-6-8.noarch.rpm
   # rpm -ivh epel-release-6-8.noarch.rpm

2. 執行 yum update 出現錯誤訊息：Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again
   

   # yum update
   Loaded plugins: fastestmirror, security
   Determining fastest mirrors
   Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again

3. 修改「/etc/yum.repos.d/epel.repo」設定
   將 baseurl 前面的 # 拿掉，mirrirlist 前面加上 #
   

   baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch
   #mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch

4. 安裝 Docker
   

   # yum install docker-io

5. 啟動 Docker
   

   # service docker start

6. 設定開機時自動啟動 Docker
   

   # chkconfig docker on
