Docker 安装 Tomcat

方法一、docker pull tomcat

查找Docker Hub上的tomcat镜像

  1. test@docker:~/tomcat$ docker search tomcat
  2. NAME                                 DESCRIPTION                                                      STARS     OFFICIAL   AUTOMATED

  6. consol/tomcat-8.0             Tomcat 8.0.15, 8080, "admin/admin"                    14                           [OK]

这里我们拉取官方的镜像

  1. test@docker:~/tomcat$ docker pull tomcat

等待下载完成后，我们就可以在本地镜像列表里查到REPOSITORY为tomcat的镜像。

  1. test@docker:~/tomcat$ docker images|grep tomcat
  2. tomcat              latest              70f819d3d2d9        7 days ago          335.8 MB

方法二、通过 Dockerfile 构建

创建Dockerfile

首先，创建目录tomcat,用于存放后面的相关东西。

  1. test@docker:~$ mkdir -p ~/tomcat/webapps ~/tomcat/logs ~/tomcat/conf

  • webapps目录将映射为tomcat容器配置的应用程序目录

  • logs目录将映射为tomcat容器的日志目录

  • conf目录里的配置文件将映射为tomcat容器的配置文件

进入创建的tomcat目录，创建Dockerfile

  1. FROM openjdk:8-jre
  3. ENV CATALINA_HOME /usr/local/tomcat
  4. ENV PATH $CATALINA_HOME/bin:$PATH
  5. RUN mkdir -p "$CATALINA_HOME"
  6. WORKDIR $CATALINA_HOME
  8. # let "Tomcat Native" live somewhere isolated
  9. ENV TOMCAT_NATIVE_LIBDIR $CATALINA_HOME/native-jni-lib

  29.             { \

通过Dockerfile创建一个镜像，替换成你自己的名字

  1. test@docker:~/tomcat$ docker build -t tomcat .

创建完成后，我们可以在本地的镜像列表里查找到刚刚创建的镜像

  1. test@docker:~/tomcat$ docker images|grep tomcat
  2. tomcat              latest              70f819d3d2d9        7 days ago          335.8 MB

使用tomcat镜像

运行容器

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

命令说明：

-p 8080:8080：将容器的8080端口映射到主机的8080端口

-v $PWD/test:/usr/local/tomcat/webapps/test：将主机中当前目录下的test挂载到容器的/test

查看容器启动情况

  1. test@docker:~/tomcat$ docker ps 
  2. CONTAINER ID    IMAGE     COMMAND              ... PORTS                             NAMES
  3. acb33fcb4beb    tomcat    "catalina.sh run"     ... 0.0.0.0:8080->8080/tcp   tomcat
