使用 Docker-Compose部署JavaWeb项目并运行JavaWeb项目

一共需要两个容器:

Tomcat

mysql

然后需要jpress的war包

创建一个新的composeJava目录，将war包放入该目录下，并且以下操作都在 该目录下进行

创建server.xml

内容如下:

<?xml version="1.0" encoding="UTF-8"?>

<Server port="8005" shutdown="SHUTDOWN">
  <Listener className="org.apache.catalina.startup.VersionLoggerListener" />
  
  
  <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />
  
  <Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" />
  <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />
  <Listener className="org.apache.catalina.core.ThreadLocalLeakPreventionListener" />

 
  <GlobalNamingResources>
    
    <Resource name="UserDatabase" auth="Container"
              type="org.apache.catalina.UserDatabase"
              description="User database that can be updated and saved"
              factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
              pathname="conf/tomcat-users.xml" />
  </GlobalNamingResources>

 
  <Service name="Catalina">
    <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443"
               maxParameterCount="1000"
               />
   
    <Engine name="Catalina" defaultHost="localhost">
      <Realm className="org.apache.catalina.realm.LockOutRealm">
        <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
               resourceName="UserDatabase"/>
      </Realm>

      <Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="true">
        <Context docBase="/usr/local/tomcat/webapps/jpress-web-newest" path=""/>
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log" suffix=".txt"
               pattern="%h %l %u %t &quot;%r&quot; %s %b" />

      </Host>
    </Engine>
  </Service>
</Server>

创建Dockerfile文件，内容如下：

FROM tomcat: 8.5
COPY  jpress-web-newest.war /usr/local/tomcat/webapps/
COPY  server.xml  /usr/local/tomcat/conf

创建docker-compose.yml，内容如下：

其中tomcat的路径要跟虚拟机的tomcat路径一致

version: "2"
services:
  web:
    build: .
    container_name: jpress 
    ports:
      - "8080:8080"
    volumes:
      - /opt/tomcat/
    depends_on:
      - db
  db:
    image: mysql:5.7
    container_name: mysql
    command: --default-authentication-plugin-mysql_native_password
    restart: always 
    ports:
      - "3306:3306"
    environment:
      MYSQL_ROOT_PASSWORD: 123
      MYSQL_ DATABASE: jpress

上传war包

以上操作全是在 composeJava文件夹下运行的

进入到docker-compose.yml的目录下,执行以下命令

然后在运行

docker-compose up -d

无报错就是成功了

启动完成之后,访问http://localhost:8080/jpress,就可以看到jpress的页面了

其中localhost是自己的ip地址
