docker部署tomcat

部署tomcat

1、准备Tomcat容器。

由于这个是Tomcat项目，所以需要得到一个Tomcat的镜像。
直接pull一个镜像即可

    docker pull tomcat

2、获取到Tomcat镜像之后，就可以run起来一个容器了，这里需要run的时候指定对应的端口映射。

root@controller:~# netstat -pltu |grep 80tcp        0      0 *:6080                  *:*                     LISTEN      4397/python     root@controller:~# docker run -i -t --name HelloDocker -p 80:8080 tomcat /bin/bashroot@a618333d5e28:/usr/local/tomcat# root@a618333d5e28:/usr/local/tomcat# lsLICENSE  NOTICE  RELEASE-NOTES  RUNNING.txt  bin  conf  include  lib  logs  native-jni-lib  temp  webapps  work run           运行一个容器 --name         后面是这个镜像的名称-p 80:8080     表示在这个容器中使用8080端口(第二个)映射到本机的端口号也为80(第一个)>-d             表示使用守护进程运行，即服务挂在后台

3、可以发现现在已经是在tomcat的安装目录下了，可以通过ls查看，然后正常启动tomcat服务器即可：

主机和容器之间传输文件

主机和容器之间传输文件的话需要用到容器的ID全称
获取方法如下：

1.先拿到容器的短ID或者指定的name。

root@controller:~# docker ps -aCONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS                           PORTS                    NAMESa618333d5e28        tomcat              "/bin/bash"              22 minutes ago      Exited (130) 3 seconds ago                                HelloDocker

2.然后根据这两项的任意一项拿到ID全称。

root@controller:~# docker inspect -f '{{.ID}}' HelloDockera618333d5e280422d9b549c59dd2c24d7d1ef30ba02e674a9662d4100adb4a24

有了这个长长的ID的话，本机和容器之间的文件传输就简单了。

docker cp 本地文件路径 ID全称:容器路径

root@controller:~# lsa  testroot@controller:~# docker cp a a618333d5e280422d9b549c59dd2c24d7d1ef30ba02e674a9662d4100adb4a24:/rootroot@controller:~# 

进入容器之后就能够看到刚才上传进来的文件了。

root@controller:~# docker start HelloDockerHelloDockerroot@controller:~# docker attach HelloDockerroot@a618333d5e28:/usr/local/tomcat# root@a618333d5e28:/usr/local/tomcat# root@a618333d5e28:/usr/local/tomcat# pwd/usr/local/tomcatroot@a618333d5e28:/usr/local/tomcat# cd /root/root@a618333d5e28:~# lsaroot@a618333d5e28:~# 

如果是容器传输文件到本地的话，反过来就好了：

docker cp ID全称:容器文件路径 本地路径

root@controller:~# docker cp a618333d5e280422d9b549c59dd2c24d7d1ef30ba02e674a9662d4100adb4a24:/root/a /tmp/root@controller:~# cd /tmp/root@controller:/tmp# lsahsperfdata_logstashhsperfdata_root

复制目录跟文件一样

root@controller:~# lsa  testroot@controller:~# docker cp test/ a618333d5e280422d9b549c59dd2c24d7d1ef30ba02e674a9662d4100adb4a24:/rootroot@controller:~# docker start HelloDockerHelloDockerroot@controller:~# docker attach HelloDockerroot@a618333d5e28:/usr/local/tomcat# root@a618333d5e28:/usr/local/tomcat# root@a618333d5e28:/usr/local/tomcat# cd /root/root@a618333d5e28:~# lsa  testroot@a618333d5e28:~# cd test/root@a618333d5e28:~/test# pwd/root/testroot@a618333d5e28:~/test#
