准备工作

用你的节点IP替换文中的 192.168.0.117、192.168.0.118

生成一对ssh密钥，替换文中的公钥和私钥（私钥使用逗号代替换行）

ssh-keygen -t rsa
cat ~/.ssh/rsa.pub
sed ':a;N;$!ba;s/\n/,/g' ~/.ssh/id_rsa

Node A & B

安装最新版 docker

yum install -y yum-utils
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
yum makecache fast
yum install -y docker-ce

配置私服

mkdir -p /etc/docker
echo '{' > /etc/docker/daemon.json
echo '    "registry-mirrors": ["https://cwxw0b5u.mirror.aliyuncs.com"],' >> /etc/docker/daemon.json
echo '    "insecure-registries": ["192.168.0.117"]' >> /etc/docker/daemon.json
echo '}' >> /etc/docker/daemon.json

创建用户，配置密钥

useradd docker -g docker
mkdir /home/docker/.ssh
echo 'ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDEpbjbi5lMWJBi8OaziaqE1bgjRrjm3KtOsZKBIlZbgfVbNXR9f7h4chOhbMoi0NAKPbvDCsrRSuH0zOZAA9X/Q+ldtBF9bAFqfd2EzXiqSR+MragQKeZVBe9coCJDpkqlvGelWfr1UWNRCsTQOLxO5ufskrOJ3yrbJYW2zfl/XStEFfjR5sSbxnYR0t6l+659Wh7K/ybMudRS4m2PTvWNeXIUYRqB8886K1K7oXOuCv658wdNj+EWB5VtaTmfDjs54C2FZ+sEQ0OUO/fg+JZxWO02iG1SALIduxKHuXHWfFMmiEZYEmYyYzBtZ2dW/yt2TOHdY7YUnK5gqCPok/ap root@localhost.localdomain' > /home/docker/.ssh/authorized_keys
chown -R docker.docker /home/docker/.ssh
chmod 400 /home/docker/.ssh/authorized_keys
chmod 500 /home/docker/.ssh

启动 docker 服务

systemctl start docker
systemctl enable docker

Node A

运行私服

docker run -d --privileged=true --restart=always -p 80:5000 -v /opt/registry:/var/lib/registry --name registry registry

本地生成一个镜像仓库服务

拉取 redis 镜像，并存储到私服中

docker pull redis
docker tag redis 192.168.0.117/redis
docker push 192.168.0.117/redis

拉取 alpine 镜像，并存储到私服中

docker pull alpine
docker tag alpine 192.168.0.117/alpine
docker push 192.168.0.117/alpine

拉取 ssgo/dock 镜像，并存储到私服中

docker pull ssgo/dock
docker tag ssgo/dock 192.168.0.117/ssgo/dock
docker push 192.168.0.117/ssgo/dock

拉取 ssgo/gateway 镜像，并存储到私服中

docker pull ssgo/gateway
docker tag ssgo/gateway 192.168.0.117/ssgo/gateway
docker push 192.168.0.117/ssgo/gateway

运行 ssgo/dock

docker run --name dock -d --restart=always --network=host -v /opt/dock:/opt/data -e 'dock_privateKey=-----BEGIN RSA PRIVATE KEY-----,MIIEowIBAAKCAQEAxKW424uZTFiQYvDms4mqhNW4I0a45tyrTrGSgSJWW4H1WzV0,fX+4eHIToWzKItDQCj27wwrK0Urh9MzmQAPV/0PpXbQRfWwBan3dhM14qkkfjK2o,ECnmVQXvXKAiQ6ZKpbxnpVn69VFjUQrE0Di8Tubn7JKzid8q2yWFts35f10rRBX4,0ebEm8Z2EdLepfuufVoeyv8mzLnUUuJtj071jXlyFGEagfPPOitSu6Fzrgr+ufMH,TY/hFgeVbWk5nw47OeAthWfrBENDlDv34PiWcVjtNohtUgCyHbsSh7lx1nxTJohG,WBJmMmMwbWdnVv8rdkzh3WO2FJyuYKgj6JP2qQIDAQABAoIBAQCCwVLmoK9BJY50,S4yLCtnYU6eJxUfDMi2yOL6aoPNdC0/S4vtfS2Kkq+3Do2vQtJnwhVXo/a8YdTtD,pE7hd+t+PXDZvpb2l69lWOXHnTxDtjWFPB8JCGNAW57qLww5gUQXaexc9TS6k/B+,/bMaZO9JY54JHw7EeSCs8Qk1IUZp2aWTDYJyGE14rfYe2IKh7trGh3lQv2QhNbMT,lR1uKubF6TrUbk+M9DMkqIozbaTOTtF4NuVn93LNiTi7RD4FwPtmKa+50MfE37kK,Un3zcHYY5URAIES9EOyUJ/zcYYcLnbSGJqlj9tWZXm0ZUKdj/sNI87cJn+xq1ImA,IfR9fig1AoGBAO/rf0zNypppZAqIw3vmkeKGOgnNUU+ycYJn/lSHn3EB9e0HDl9S,zvPVbSHeUwjld0Ss4w09HriyTsY29q1U6xbZ+lKF9geELjBLq1W+lq5s7L1+P0xl,X1VzSsmSwfdJ9yRFQERXeGyIBDNYs1lOXrs04E4oinrbZs7GDCgXerWvAoGBANHT,wxTYhYMCj+ujqylHeS8mm9Uk0tnvxMLeMdrMUHpV/t8YTVUdxKitrb4e7tvJ6a4h,kxb05Aa9VXSj5Hq8c8VYY7n/NnmNicym9LNe9yMaPSuwAtbQRPqrjS0saNJl0Ecv,Lx0cN4fBMyevd4AlJzUX8vQ4HjebK69Scr1p3YcnAoGAUQOintq22WFRKMV5zTLU,fDt7CahNFq5Y6gIXvY92ZYCV/I3vanzZ6Thee5tJSq3Bkm0W1neXEiMTupcAwRL1,t2evwYH+zBb0SdajanbLBuc9IdeppDBu+rnNvTdTTB+r1pGT2//1aCCd2oDPPw7Z,qjl2rK2/5TCFDLmPjVIwW30CgYAH33UzZAhmaQMzaTmz282tOjqgnbgXm0p7sVCX,kBD49h8RCd1k8y/80D9zob9+ma3d7b6SHvArXJFHRhr9i/KgFffv86Z8mxXvitgl,nsuREpv29qy0mK3t5d/vMPph4pYVBa0z32op+tLLi2bldP9qm5JvHWfs2DKkamiJ,uN4qAwKBgDb1BvQJgQ+2BEzYGC1vEr01GAcLmN48hxFV4YdK89z/cdof+c4NDaiT,rKuWWwYWx5lI0XNqS16caFDa47hwjT2VwHGOTFuwRa1QnnpWE9RQ+tLFmwZ1if5n,yHTxuoLlVQJuTsq+WywNdKMMTJOoPsgKUW5QPVA/VMe118TXIyII,-----END RSA PRIVATE KEY-----' 192.168.0.117/ssgo/dock
