docker下载地址：https://www.docker.com/get-started
首先注册阿里云容器镜像服务
地址：https://cr.console.aliyun.com/cn-hangzhou/instances/repositories
注册好之后选择镜像加速，操作如下：
复制加速地址，然后打开docker的 Preferences -》Docker Engine ，编辑json
在原来的json串中添加 registry-mirrors ，然后重新启动docker
选择镜像仓库 -》创建镜像仓库 -》输入仓库名，描述等信息，如下图：
点击下一步选择本地仓库，最后点击创建镜像仓库即可
我们选择centos作为基础容器，然后在这个基础容器之上安装ftp服务，最后打成一个ftp服务镜像上传到阿里云仓库中
在构建镜像之前，我们需要配置以下vsftp的配置文件，我们把配置文件放在宿主机的 /data 目录下，配置文件名为vsftpd.conf，其内容如下：
# vsftp默认加载配置文件的位置 # Example config file /etc/vsftpd/vsftpd.conf # 允许匿名用户登陆 anonymous_enable=YES # 允许写数据都根目录 allow_writeable_chroot=YES # # 是否允许本地用户登陆 local_enable=YES # # 是否允许登陆用户有写权限。属于全局设置，默认值为YES write_enable=YES # # 默认的umask码，用户决定用户创建文件时的默人文件权限 local_umask=022 # # 是否允许匿名用户上传文件，不过前提是write_enable=YES并且匿名用户拥有该文件夹的写入权限 anon_upload_enable=YES # # 如果设为YES，则允许匿名登入者有新增目录的权限，只有在write_enable=YES时，此项才有效。当然，匿名用户必须要有对上层目录的写入权。默认值为NO anon_mkdir_write_enable=YES anon_other_write_enable=YES # # dirmessage_enable=YES # # The target log file can be vsftpd_log_file or xferlog_file. # This depends on setting xferlog_std_format parameter xferlog_enable=YES # # Make sure PORT transfer connections originate from port 20 (ftp-data). connect_from_port_20=YES # # If you want, you can arrange for uploaded anonymous files to be owned by # a different user. Note! Using "root" for uploaded files is not # recommended! #chown_uploads=YES #chown_username=whoever # # The name of log file when xferlog_enable=YES and xferlog_std_format=YES # WARNING - changing this filename affects /etc/logrotate.d/vsftpd.log #xferlog_file=/var/log/xferlog # # Switches between logging into vsftpd_log_file and xferlog_file files. # NO writes to vsftpd_log_file, YES to xferlog_file xferlog_std_format=YES # # You may change the default value for timing out an idle session. #idle_session_timeout=600 # # You may change the default value for timing out a data connection. #data_connection_timeout=120 # # It is recommended that you define on your system a unique user which the # ftp server can use as a totally isolated and unprivileged user. #nopriv_user=ftpsecure # # Enable this and the server will recognise asynchronous ABOR requests. Not # recommended for security (the code is non-trivial). Not enabling it, # however, may confuse older FTP clients. #async_abor_enable=YES # # By default the server will pretend to allow ASCII mode but in fact ignore # the request. Turn on the below options to have the server actually do ASCII # mangling on files when in ASCII mode. # Beware that on some FTP servers, ASCII support allows a denial of service # attack (DoS) via the command "SIZE /big/file" in ASCII mode. vsftpd # predicted this attack and has always been safe, reporting the size of the # raw file. # ASCII mangling is a horrible feature of the protocol. #ascii_upload_enable=YES #ascii_download_enable=YES # # You may fully customise the login banner string: #ftpd_banner=Welcome to blah FTP service. # # You may specify a file of disallowed anonymous e-mail addresses. Apparently # useful for combatting certain DoS attacks. #deny_email_enable=YES # (default follows) #banned_email_file=/etc/vsftpd/banned_emails # # You may specify an explicit list of local users to chroot() to their home # directory. If chroot_local_user is YES, then this list becomes a list of # users to NOT chroot(). #chroot_local_user=YES #chroot_list_enable=YES # (default follows) #chroot_list_file=/etc/vsftpd/chroot_list # # You may activate the "-R" option to the builtin ls. This is disabled by # default to avoid remote users being able to cause excessive I/O on large # sites. However, some broken FTP clients such as "ncftp" and "mirror" assume # the presence of the "-R" option, so there is a strong case for enabling it. #ls_recurse_enable=YES # # When "listen" directive is enabled, vsftpd runs in standalone mode and # listens on IPv4 sockets. This directive cannot be used in conjunction # with the listen_ipv6 directive. listen=YES # # This directive enables listening on IPv6 sockets. To listen on IPv4 and IPv6 # sockets, you must run two copies of vsftpd with two configuration files. # Make sure, that one of the listen options is commented !! #listen_ipv6=YES pam_service_name=vsftpd userlist_enable=YES tcp_wrappers=YES anon_root=/data/ftpUser no_anon_password=YES local_root=/data/ftpUser ftp_username=ftpUser # 开启被动模式 pasv_enable=YES # 被动模式可以开启的端口范围 pasv_min_port=21100 pasv_max_port=21110然后我们准备一个Dockfile文件，放在/data目录下，文件名为Dockfile，其内容如下：
# 拉取基础镜像 FROM centos:7 # 维护人 MAINTAINER 951645267@qq.com # 将vsf配置文件复制到容器的/etc/vsftpd目录下 RUN mkdir -p /etc/vsftpd ADD vsftpd.conf /etc/vsftpd # 安装ftp RUN yum install -y vsftpd RUN mkdir /data # 创建用户ftpUser，用户目录为/data/ftpUser # -s 后面的参数 /bin/bash 表示当用户 ftpUser 登陆时，默认使用的 bash RUN useradd -d /data/ftpUser -s /bin/bash ftpUser # 给ftpUser设置密码 123 RUN echo "ftpUser:123" | chpasswd RUN chmod 755 /data/ftpUser # 起声明作用，告诉他人我的服务在这些端口，并不是说我只能访问这些接口 # 接口能否访问由启动容器的命令 -p 决定 EXPOSE 20 21 # 运行容器时启动ftp服务, 但是vsftpd时个后台服务，一执行 # 就会退出容器，所以需要加个 tail -f /dev/null 避免容器退出 ENTRYPOINT /usr/sbin/vsftpd && tail -f /dev/null # 使用 systemctl 管理服务，关于 systemctl 的使用可参考 https://blog.csdn.net/masteryee/article/details/83689990 # RUN systemctl start vsftp.service准备好 Dockerfile 之后我们就可以构建一个安装了ftp的镜像了（我这里创建的dockerfile文件使用的是默认的名字 Dockerfile）
# sudo docker build -t name:tag . sudo docker build -t registry.cn-hangzhou.aliyuncs.com/wuzh-yun/ftp:1.0.0 .构建的镜像名为 registry.cn-hangzhou.aliyuncs.com/wuzh-yun/ftp，对应的阿里云镜像仓库格式为 域名/命名空间/仓库名，如下为构建过程的输出内容：
构建完成后，我们查看一下本地仓库是否出现了一个叫做registry.cn-hangzhou.aliyuncs.com/wuzh-yun/ftp:1.0.0的镜像
sudo docker images启动容器
# 运行镜像，将容器的端口21，20，21100-21110映射到宿主机的21，20，21100-21110 # 将宿主机的/data/ftp挂载到容器的/data/ftpUser目录下，这样我们上传文件到 /data/ftpUser 相当于把文件存在到宿主机的/data/ftp # 将配置文件vsftpd.conf挂载到容器的/etc/vsftpd/vsftpd.conf，ftp默认加载配置的路径 sudo docker run -dit -p 21:21 -p 20:20 -p 21100-21110:21100-21110 -v /data/ftp:/data/ftpUser --name ftp registry.cn-hangzhou.aliyuncs.com/wuzh-yun/ftp:1.0.0如果挂载目录时报如下错误：
那么请配置共享目录，操作如下：
重启docker
如果你的mac没有安装ftp，可以执行以下命令：
brew install telnet brew install inetutils brew link --overwrite inetutils如果 brew 也没有安装的话，请参考：https://zhuanlan.zhihu.com/p/111014448。 如果你有VPN的话，直接上官网：https://brew.sh/index_zh-cn.html
执行 ftp ip port，然后输入用户名和密码
首先需要先登陆，命令如下：
sudo docker login --username=您的用户名 registry.cn-hangzhou.aliyuncs.com然后输入密码登陆，最后推送镜像至阿里云镜像仓库
sudo docker push registry.cn-hangzhou.aliyuncs.com/wuzh-yun/ftp:1.0.0
