对应系统下载.
安装好,在托盘图标可以看到状态,启动成功
查看版本
docker image COMMAND
show containers
docker image ps
基本命令平时就查看,其他build等简单使用
docker container COMMAND
show containers
docker container ls [-a] 显示全部(包含未运行的)
image就是镜像,静态的,通过image可以生成container
docker pull COMMAND
拉取image
docker run COMMAND
docker run --name name -d imagename
通过image创建container并运行 -d,dettach
开放端口
docker run -p outer:inner imagename
outer: 外部端口 inner: 内部端口
比如 8080:80 ,外部宿主计算机端口映射到docker内部80端口
开放多个端口
-p 8080:80 -p 2222:222 -p etc...
删除container
docker rm -f containername
删除image
docker rmi imagename
share file from host
docker run --name name -v /some/folder:/usr/local/nginx/html:ro -p 8080:80 nginx:latest
going inside container
docker exec -it containername bash(/bin/sh)
Dockerfile
docker build
docker push
推送到duckerhub或者其他docker仓库
.dockerignore

Behavior
# comment
Ignored.
*/temp*
Exclude files and directories whose names start with temp in any immediate subdirectory of the root. For example, the plain file /somedir/temporary.txt is excluded, as is the directory /somedir/temp.
*/*/temp*
Exclude files and directories starting with temp from any subdirectory that is two levels below the root. For example, /somedir/subdir/temporary.txt is excluded.
temp?
Exclude files and directories in the root directory whose names are a one-character extension of temp. For example, /tempa and /tempb are excluded.
此文件忽略通过规则定义的文件 然而,往往忽略的,需要在dockerfile中重新RUN来在部署时候生成module等
Alpine
很精简的,体积很小.适合集成docker中
一个使用例子 36.8MB
