章节的步骤，使用官方提供的 Dockerfile.base 自行打包。 # find ./ -type f|grep "Dockerfile$"|grep -v "\.D"|xargs sed -i "s#photon:2.0#photon:3.0#g" # sed -i "s/goharbor/liar/g" ./make/photon/log/Dockerfile # find ./make/photon /make/photon -type f|grep "Dockerfile$"|grep -v "\.D"|xargs sed -i "s/goharbor/glongzh/g" 步骤 5 拉取 golang 1.12.12 官网镜像。 # docker pull golang:1.12.12 步骤 6 编译、安装和启动 harbor 服务。 # make install GOBUILDIMAGE=golang:1 CentOS 7.6 4 软件编译 7 步骤 1 复制 Dockerfile。 # cd make/photon/core # mkdir base # cp Dockerfile.base base/Dockerfile # cd base 步骤 2 修改 Dockerfile。 将 photon:2.0 修改为 photon:3.0，是因为 photon
