在Docker容器中运行Tomcat – 容器在启动时退出
我正在学习Docker并尝试构build一个Dockerfile，它将使用docker-compose而不是docker来运行Tomcat。
Dockerfile如下：
# Base the image on tomcat FROM tomcat:7.0.82-jre7 WORKDIR /usr/local/tomcat # Install updates & commands RUN apt-get update && apt-get install -y vim # Add some pre-set files COPY tomcat-users.xml /usr/local/tomcat/conf # Run the Tomcat on port 8080 EXPOSE 8080 # Start tomcat # CMD ["bin/startup.sh", "run"] docker-compose.yml文件如下：
version: '3' services: tomcat: image: tomcat:7.0 build: context: ./ dockerfile: Dockerfile ports: - 8888:8080 container_name: tomcat7 volumes: - ./tomcat7:/usr/local/tomcat:rw entrypoint: /bin/bash /usr/local/tomcat/bin/startup.sh tty: true
tomcat7泊坞窗容器启动，但在退出模式。
任何想法如何使其运行？
容器现在已经启动，正在运行下面的configuration。 但是，当我在浏览器中运行http：// localhost：8888时，什么也不打开！ Apache Tomcat没有打开
FROM tomcat:7.0.82-jre7 RUN apt-get update && apt-get install -y vim ADD tomcat-users.xml /usr/local/tomcat/conf EXPOSE 8080 CMD chmod +x /usr/local/tomcat/bin/catalina.sh CMD ["catalina.sh", "run"] version: '3' services: tomcat: container_name: tomcat7 hostname: tomcat7 build: context: ./ dockerfile: Dockerfile args: buildno: 1 image: bhaidar/tomcat:1.0 volumes: - ./tomcat7:/usr/local/tomcat/webapps ports: - "8888:8080" tty: true
以下是docker inspect的输出

其实这个问题是在volumes 。 它正在清除容器内的webapps文件夹。
所以我不得不把这些volumes设置为：
volumes: - ./tomcat7/index.html:/usr/local/tomcat/webapps/index.html
