Ubuntu16.04构建docker镜像

保存对容器的修改自定义镜像的能力以软件的形式打包并分发服务及其运行环境

docker commit 通过容器构建

docker commit [OPTIONS] CONTAINER [REPOSITORY[:TAG]] -a --author="" 镜像的作者 -m --message=" commit message -p --pause=true commit时终止容器 eggyer@ubuntu:/usr/local$ docker commit -a "eggyer" -m "test" commit_test eggyer/commit_test c6015f3dbf2b0641841e70b7998ca2154640e01169f8f3914b8e8ea9b8e46c9d eggyer@ubuntu:/usr/local$ docker images REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE eggyer/commit_test latest c6015f3dbf2b 16 seconds ago 132.8 MB <none> <none> 6653e655da79 About a minute ago 132.8 MB ubuntu latest bea8f41ae3e8 9 days ago 128.1 MB ubuntu16.04 latest bea8f41ae3e8 9 days ago 128.1 MB eggyer/ubuntu16.04 latest bea8f41ae3e8 9 days ago 128.1 MB eggyer@ubuntu:/usr/local$

docker build 通过dockerfile文件构建

创建dockerfile文件使用docker build命令

dockerfile文件包含了:系统版本名称,作者信息,要执行的命令,暴露的端口等一系列基本信息

eggyer@ubuntu:~$ cd /usr/local eggyer@ubuntu:/usr/local$ ls bin dockerfile etc games include lib man nginx sbin share src eggyer@ubuntu:/usr/local$ cd dockerfile/df_test1/ eggyer@ubuntu:/usr/local/dockerfile/df_test1$ ls Dockerfile eggyer@ubuntu:/usr/local/dockerfile/df_test1$ sudo vim Dockerfile [sudo] eggyer 的密码： eggyer@ubuntu:/usr/local/dockerfile/df_test1$ sudo vim Dockerfile eggyer@ubuntu:/usr/local/dockerfile/df_test1$ docker build[OPTIONS] PATH |URL| - --force-rm=false --no-cache=false --pull=false -q --quiet=false --rm=true -t --tag="" 指定dockertag的名字 eggyer@ubuntu:/usr/local/dockerfile/df_test1$ docker build -f "Dockerfile" -t='eggyer/df_test1' .
