Docker 装置 Tomcat

方式一、docker pull tomcat

查找 快乐飞艇是犯法的吗:Docker Hub 上的 Tomcat 镜像:

能够经由过程 Sort by 检查其余版本的 tomcat,默许是最新版本 tomcat:latest

另外,咱们还能够用 docker search tomcat 号令来检查可用版本:

jishudaxue@jishudaxue:~/tomcat$ docker search tomcat

这里咱们拉取官方的镜像:

jishudaxue@jishudaxue:~/tomcat$ docker pull tomcat

期待下载实现后,咱们就能够在本地镜像列表里查到 REPOSITORY 为 tomcat 的镜像。

jishudaxue@jishudaxue:~/tomcat$ docker images|grep tomcat
tomcat              latest              70f819d3d2d9        7 days ago          335.8 MB

方式二、经由过程 Dockerfile 构建

建立Dockerfile

起首,建立目次tomcat,用于寄存前面的相干工具。

jishudaxue@jishudaxue:~$ mkdir -p ~/tomcat/webapps ~/tomcat/logs ~/tomcat/conf

webapps 目次将映照为 tomcat 容器设置装备摆设的利用法式目次。

logs 目次将映照为 tomcat 容器的日记目次。

conf 目次里的设置装备摆设文件将映照为 tomcat 容器的设置装备摆设文件。

进入建立的 tomcat 目次,建立 Dockerfile。

经由过程 Dockerfile 建立一个镜像,替代成你本身的名字:

jishudaxue@jishudaxue:~/tomcat$ docker build -t tomcat .

建立实现后,咱们能够在本地的镜像列表里查找到方才建立的镜像:

jishudaxue@jishudaxue:~/tomcat$ docker images|grep tomcat
tomcat              latest              70f819d3d2d9        7 days ago          335.8 MB

利用 tomcat 镜像

运转容器

jishudaxue@jishudaxue:~/tomcat$ docker run --name tomcat -p 8080:8080 -v $PWD/test:/usr/local/tomcat/webapps/test -d tomcat  
acb33fcb4beb8d7f1ebace6f50f5fc204b1dbe9d524881267aa715c61cf75320
jishudaxue@jishudaxue:~/tomcat$

号令申明:

-p 8080:8080:将容器的 8080 端口映照到主机的 8080 端口。

-v $PWD/test:/usr/local/tomcat/webapps/test:将主机中以后目次下的 test 挂载到容器的 /test。

检查容器启动环境

jishudaxue@jishudaxue:~/tomcat$ docker ps 
CONTAINER ID    IMAGE     COMMAND               ... PORTS                    NAMES
