操作

/ 后端 / 部署 / Docker / 操作

•

docker search name

查找名为name的镜像在服务器上

•

docker pull name

拉取镜像到本地，name为全称。

•

docker run --name testTomcat -p 8080:8080 -v /usr/test:/usr/local/tomcat/webapps/test -d tomcat

以名字为tomcat的镜像创建一个名为testTomcat的容器并运行

image —run—>container

•

--name testTomcat 表示上一步安装的镜像名称

•

-p 8080:8080 表示将容器的8080port映射到本机的8080port端口

•

-v /usr/test:/usr/local/tomcat/webapps/test 表示将本机下的usr目录下的test文件夹映射到容器tomcat的webapps文件夹下

•

-d tomcat 表示在后台守护进程的方式启动（不进入后台启动），指定上一步安装的镜像名称

•

docker exec -it name bash

可以用name也可以用id，id不用打全，能够区分就行。

•

docker commit 容器名镜像名

复刻容器生成镜像。

•

docker build -t 镜像名 .

. 表示当前文件夹，以当前文件夹里的Dockerfile 文件生成一个镜像。

from tomcat
add ./ /usr/local/tomcat/webapps/ROOT/

•

第一句是表示基于tomcat和这个镜像创建这个镜像

•

第二句表示把当前文件夹的东西复制到镜像的/usr/local/tomcat/webapps/ROOT/

创建tomcat的Dockerfile文件
