Docker 部署tomcat

搜索 tomcat

下載tomcat

啟動tomcat

啟動 tomcat 容器，將容器的 8080 端口與外網的 8888端口進行映射

[root@VM-0-7-centos ~]# docker run -d --name artisanTomcat -p 8888:8080 tomcat 2a0e6e88661732a710d8a30d9fda6d73c25478fe352a59f520cb753da6442f7b [root@VM-0-7-centos ~]# [root@VM-0-7-centos ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 2a0e6e886617 tomcat "catalina.sh run" 36 seconds ago Up 34 seconds 0.0.0.0:8888->8080/tcp, :::8888->8080/tcp artisanTomcat bb19cf9ced23 nginx "/docker-entrypoint.…" 22 minutes ago Up 22 minutes 0.0.0.0:7788->80/tcp, :::7788->80/tcp artisanNginx [root@VM-0-7-centos ~]#

訪問tomcat

訪問下試試

不應該啊，看看Tomcat下的webapps

[root@VM-0-7-centos ~]# docker exec -it artisanTomcat /bin/bash root@2a0e6e886617:/usr/local/tomcat# ls -al total 176 drwxr-xr-x 1 root root 4096 Sep 29 11:23 . drwxr-xr-x 1 root root 4096 Sep 29 11:13 .. -rw-r--r-- 1 root root 18994 Sep 6 16:22 BUILDING.txt -rw-r--r-- 1 root root 6210 Sep 6 16:22 CONTRIBUTING.md -rw-r--r-- 1 root root 60269 Sep 6 16:22 LICENSE -rw-r--r-- 1 root root 2333 Sep 6 16:22 NOTICE -rw-r--r-- 1 root root 3372 Sep 6 16:22 README.md -rw-r--r-- 1 root root 6905 Sep 6 16:22 RELEASE-NOTES -rw-r--r-- 1 root root 16517 Sep 6 16:22 RUNNING.txt drwxr-xr-x 2 root root 4096 Sep 29 11:24 bin drwxr-xr-x 1 root root 4096 Oct 6 13:16 conf drwxr-xr-x 2 root root 4096 Sep 29 11:23 lib drwxrwxrwx 1 root root 4096 Oct 6 13:16 logs drwxr-xr-x 2 root root 4096 Sep 29 11:24 native-jni-lib drwxrwxrwx 2 root root 4096 Sep 29 11:23 temp drwxr-xr-x 2 root root 4096 Sep 29 11:23 webapps drwxr-xr-x 7 root root 4096 Sep 6 16:22 webapps.dist drwxrwxrwx 2 root root 4096 Sep 6 16:22 work root@2a0e6e886617:/usr/local/tomcat# cd webapps root@2a0e6e886617:/usr/local/tomcat/webapps# ls root@2a0e6e886617:/usr/local/tomcat/webapps# pwd /usr/local/tomcat/webapps root@2a0e6e886617:/usr/local/tomcat/webapps#

查看webapps & 修復問題

進入 tomcat 容器 ，發現webapps 下面什么都沒有 ， 阿里云鏡像 默認是最小的鏡像，所有不必要的都剔除了，保證最小可運行環境

將webapps.dist 目錄下的文件拷貝到 webapps下面 ，然后刷新頁面就可以看到tomcat頁面了

root@2a0e6e886617:/usr/local/tomcat# cd .. root@2a0e6e886617:/usr/local/tomcat# cp -r webapps.dist/* webapps root@2a0e6e886617:/usr/local/tomcat# cd webapps root@2a0e6e886617:/usr/local/tomcat/webapps# ls -al total 32 drwxr-xr-x 1 root root 4096 Oct 6 13:22 . drwxr-xr-x 1 root root 4096 Sep 29 11:23 .. drwxr-xr-x 3 root root 4096 Oct 6 13:22 ROOT drwxr-xr-x 15 root root 4096 Oct 6 13:22 docs drwxr-xr-x 7 root root 4096 Oct 6 13:22 examples drwxr-xr-x 6 root root 4096 Oct 6 13:22 host-manager drwxr-xr-x 6 root root 4096 Oct 6 13:22 manager root@2a0e6e886617:/usr/local/tomcat/webapps# root@2a0e6e886617:/usr/local/tomcat/webapps#

重新訪問tomcat

刷新頁面，無需重啟容器

啟動nginx

• -d 后臺啟動
• –name 給容器命名
• -p 宿主機端口：容器端口

[root@VM-0-7-centos ~]# docker run -d --name artisanNginx -p 7788:80 nginx bb19cf9ced237313ef6cc0f332b1ed0f4ad8632c14a719de801ceb539ce41576 [root@VM-0-7-centos ~]# [root@VM-0-7-centos ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES bb19cf9ced23 nginx "/docker-entrypoint.…" 3 seconds ago Up 3 seconds 0.0.0.0:7788->80/tcp, :::7788->80/tcp artisanNginx [root@VM-0-7-centos ~]# [root@VM-0-7-centos ~]# [root@VM-0-7-centos ~]#
