如何包装成一个docker镜像?

Question

有一个应用是这样安装的，以root身份登陆vps（debian11):

#编译准备apt install git cvs zlib1g-dev make gcc -y#编译安装libowfatcvs -d :pserver:[e-mail]:/cvs -z9 co libowfatcd libowfatmakemake install#编译安装opentrackergit clone git://erdgeist.org/opentrackercd  ../opentrackermakemake  install#将opentracker设置成一个service, 端口设置为6881mv opentracker /usr/bincd  ..cat <<EOF >/etc/systemd/system/opentracker.service[Unit]Description=opentracker server[Service]User=rootExecStart=/usr/bin/opentracker -p 6881 -P 681Restart=on-abortLimitCORE=infinityLimitNOFILE=infinityLimitNPROC=infinity[Install]WantedBy=multi-user.targetEOF#为端口6881打开防火墙apt install ufwufw  allow   6881#启动servicesystemctl enable /etc/systemd/system/opentracker.servicesystemctl start opentracker

我可否为这个应用制作一个docker镜像呢？用docker run来达到我上面那些代码的目的？

报错了

我的镜像源

cat  /etc/docker/daemon.json{    "registry-mirrors": [        "https://docker.m.daocloud.io",        "https://dockerproxy.com",        "https://docker.mirrors.ustc.edu.cn",        "https://docker.nju.edu.cn",        "http://hub-mirror.c.163.com"    ]}

我的本地代理可以使用

curl --socks5-hostname 127.0.0.1:10800 -s  -w "%{http_code}\n" -o /dev/null www.baidu.com200

在构建镜像时，使用代理

 sudo docker build . -t opentracker:v1  --build-arg https_proxy=socks5://127.0.0.1:10800[+] Building 51.4s (3/3) FINISHED                                                                                                                             docker:default => [internal] load .dockerignore                                                                                                                                       0.8s => => transferring context: 2B                                                                                                                                         0.0s => [internal] load build definition from dockerfile                                                                                                                    0.5s => => transferring dockerfile: 445B                                                                                                                                    0.0s => ERROR [internal] load metadata for docker.io/library/debian:11                                                                                                     49.0s------ > [internal] load metadata for docker.io/library/debian:11:------dockerfile:8--------------------   6 |     RUN cd opentracker && make    7 |        8 | >>> FROM debian:11   9 |     COPY --from=builder /opentracker/opentracker /opt  10 |     EXPOSE 6881--------------------ERROR: failed to solve: debian:11: failed to do request: Head "https://docker.m.daocloud.io/v2/library/debian/manifests/11?ns=docker.io": socks connect tcp 127.0.0.1:8080->docker.m.daocloud.io:443: EOF

还是报错

终于成功了。

{    "registry-mirrors": [        "https://docker.m.daocloud.io",        "https://dockerproxy.com",        "https://docker.mirrors.ustc.edu.cn",        "https://docker.nju.edu.cn",        "http://hub-mirror.c.163.com",        "http://mirrors.ustc.edu.cn/",        "http://mirror.azure.cn/",        "https://cr.console.aliyun.com"    ]}

可以，我按照你的脚本写了下面这个Dockerfile，如下：

# 这是一个多阶段构建的Dockerfile，这一部分是安装编译环境，和进行编译。FROM debian:11 as builderRUN apt update && apt install -y git cvs zlib1g-dev make gcc RUN cvs -d :pserver:[e-mail]:/cvs -z9 co libowfatRUN cd libowfat && make && make install RUN git clone git://erdgeist.org/opentracker RUN cd opentracker && make # 这个阶段是打包镜像，将上一个阶段编译出来的二进制文件拷贝到一个新的镜像中，目的是为了降低镜像的大小。FROM debian:11COPY --from=builder /opentracker/opentracker /optEXPOSE 6881ENTRYPOINT [ "/opt/opentracker" ]CMD [ "-p", "6881", "-P", "681" ]

复制上面的内容，重命名为Dockerfile，放到任意一个空目录，然后在这个目录下执行

docker build . -t opentracker:v1

完成之后会生成一个名为opentracker:v1的镜像
