#### 练习
|
|
|
|
|
|
> Docker 安装 Nginx
|
|
|
|
|
|
|
|
|
|
|
|
```shell
|
|
|
lejings@ljs-Ubuntu-desktop:/home$ docker images
|
|
|
REPOSITORY TAG IMAGE ID CREATED SIZE
|
|
|
portainer/portainer-ce latest 0c03664af9ed 4 weeks ago 308MB
|
|
|
nginx latest 9bea9f2796e2 7 weeks ago 192MB
|
|
|
mysql latest 56a8c14e1404 3 months ago 603MB
|
|
|
hello-world latest d2c94e258dcb 20 months ago 13.3kB
|
|
|
centos latest 5d0da3dc9764 3 years ago 231MB
|
|
|
lejings@ljs-Ubuntu-desktop:/home$ docker run -d --name nginx01 -p 3344:80 nginx
|
|
|
c6376749820f8a9e7b2e45bdf392f718629eb6114f201f8e58962d4073d9e9b6
|
|
|
lejings@ljs-Ubuntu-desktop:/home$ docker ps
|
|
|
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
|
|
|
c6376749820f nginx "/docker-entrypoint.…" 6 seconds ago Up 5 seconds 0.0.0.0:3344->80/tcp, [::]:3344->80/tcp nginx01
|
|
|
|
|
|
```
|
|
|
|
|
|
每次更改nginx等相关文件，都要进入容器，于是提出在容器外部提供一个映射路径，达到自动修改
|
|
|
|
|
|
|
|
|
|
|
|
> Docker 安装 Tomcat
|
|
|
|
|
|
|
|
|
|
|
|
官方使用说明
|
|
|
|
|
|
```shell
|
|
|
docker run -it --rm tomcat:9.0
|
|
|
即用在测试场景中，用完即删
|
|
|
#先下载再启动方式
|
|
|
|
|
|
测试访问响应404，证明镜像中tomcat不完整
|
|
|
root@ca1ad6b59e59:/usr/local/tomcat# ls
|
|
|
bin CONTRIBUTING.md LICENSE NOTICE RUNNING.txt webapps
|
|
|
BUILDING.txt filtered-KEYS logs README.md temp webapps.dist
|
|
|
conf lib native-jni-lib RELEASE-NOTES upstream-KEYS work
|
|
|
root@ca1ad6b59e59:/usr/local/tomcat# cd webapps
|
|
|
root@ca1ad6b59e59:/usr/local/tomcat/webapps# ls
|
|
|
root@ca1ad6b59e59:/usr/local/tomcat/webapps#
|
|
|
拷贝初始文件
|
|
|
root@ca1ad6b59e59:/usr/local/tomcat# cp -r webapps.dist/* webapps
|
|
|
root@ca1ad6b59e59:/usr/local/tomcat# cd webapps
|
|
|

|
|
|
root@ca1ad6b59e59:/usr/local/tomcat/webapps#
|
|
|
|
|
|
```
|
|
|
|
|
|
每次更改tomcat等相关文件，都要进入容器，于是提出在容器外部提供一个映射路径，达到自动修改
