那么如果是从我Docker入门文章过来的或者是对Docker有个基本了解的小伙伴们现在跟我一起来了解一下在Docker中部署Tomcat的步骤吧。

步骤一：下载Tomcat镜像

PS C:\Users\ASUS> docker pull tomcat                                                                                    
Using default tag: latest
latest: Pulling from library/tomcat
647acf3d48c2: Pull complete                                                                                             
b02967ef0034: Pull complete                                                                                             
e1ad2231829e: Pull complete                                                                                             
5576ce26bf1d: Pull complete                                                                                             
26518d6c686a: Pull complete                                                                                             
cdb1f4e0dbfd: Pull complete                                                                                             
1d872b5136cc: Pull complete                                                                                             
0b9db4d94c97: Pull complete                                                                                             
03ee64d25ffd: Pull complete                                                                                             
45a601314df9: Pull complete                                                                                             
Digest: sha256:93ff3bc7fb766a9bb5bb0d1f925f9d8795594d87e8365164908ddddcdaa75ff4
Status: Downloaded newer image for tomcat:latest
docker.io/library/tomcat:latest

步骤二：运行镜像

PS C:\Users\ASUS> docker run -d -p 3344:8080 --name tomcat01 tomcat
ce3c3f11bf37d42e399575468c673303f24aaef6818c1f2dc6d9bb02cb753c91                                                

步骤三：测试运行

访问地址：localhost:3344

这里是因为从阿里云下载下来的tomcat镜像是最精简的，少了一些不必要的配置，接下来我们来配置一下

步骤四：配置

这里webapps文件夹里面是空的，我们可以将webapps.dist里的内容复制过来

PS C:\Users\ASUS> docker exec -it tomcat01 /bin/bash
root@ce3c3f11bf37:/usr/local/tomcat# ls
BUILDING.txt     LICENSE  README.md      RUNNING.txt  conf  logs            temp     webapps.dist
CONTRIBUTING.md  NOTICE   RELEASE-NOTES  bin          lib   native-jni-lib  webapps  work
root@ce3c3f11bf37:/usr/local/tomcat# cp -r webapps.dist/* webapps
root@ce3c3f11bf37:/usr/local/tomcat# ls
BUILDING.txt     LICENSE  README.md      RUNNING.txt  conf  logs            temp     webapps.dist
CONTRIBUTING.md  NOTICE   RELEASE-NOTES  bin          lib   native-jni-lib  webapps  work
root@ce3c3f11bf37:/usr/local/tomcat# cd webapps
root@ce3c3f11bf37:/usr/local/tomcat/webapps# ls
ROOT  docs  examples  host-manager  manager
