Question

我有这个撰写文件，我希望有一个应用程序有两个运行MySql和Mongodb的数据库。所有这些都装入容器并最终连接起来。

version : '2'
services:

springappserver:
build:
  context: . 
  dockerfile: springapp.dockerfile
ports: 
  - "8081:8081"
networks:
  - net-spring-db1
  - net-spring-db2
volumes:
  - .:/vol/development
depends_on:
  - mysqldbserver
  - mongodbserver

mongodbserver:
build:
  context: . 
  dockerfile: mongodb.dockerfile
ports:
  - "27017:27017"
networks:
  - net-spring-db2
volumes:
   - ./data/db:/data/db
container_name: mongodbserver

mysqldbserver:
build:
  context: . 
  dockerfile: mysqldb.dockerfile
ports:
  - "3306:3306"
networks:
  - net-spring-db1
environment:
  MYSQL_DATABASE: testdb1
  MYSQL_USER: myuser
  MYSQL_PASSWORD: mypassword
  MYSQL_ROOT_PASSWORD: myrootpassword
  MYSQL_DATABASE: testdb2
  MYSQL_USER: myuser
  MYSQL_PASSWORD: mypassword
  MYSQL_ROOT_PASSWORD: myrootpassword
container_name: mysqldbserver

networks:
 net-spring-db1:
  driver: bridge
 net-spring-db2:
  driver: bridge

我还有3个dockerfiles

第一个是应用程序：

FROM java:8
# maintainer
MAINTAINER Bill
# update packages and install maven
 RUN  \
 export DEBIAN_FRONTEND=noninteractive && \
 sed -i 's/# \(.*multiverse$\)/\1/g' /etc/apt/sources.list && \
 apt-get update && \
 apt-get -y upgrade && \
 apt-get install -y vim wget curl maven
# attach volumes
 VOLUME /vol/development
# create working directory
 RUN mkdir -p /vol/development
 WORKDIR /vol/development
# maven exec
 CMD ["mvn", "clean", "package", "exec:java"]

第二个用于MySql服务器：

FROM mysql/mysql-server
MAINTAINER Bill
# Copy the database initialize script:
# Contents of /docker-entrypoint-initdb.d are run on mysqld startup
ADD  mysql/ /docker-entrypoint-initdb.d/

第三个是Mngodb：

FROM mongo:3.4
MAINTAINER Bill
# assume you are in mongo bin directory
RUN mongod

1）我的问题是最后一个挂起等待，所以我怀疑它需要一些参数才能完美运行。

2）我的撰写yml文件是否正确或需要调整？

Answer 1

您的mongo Dockerfile不正确。在构建图像时，您不应该运行mongod。 RUN命令将在映像构建时执行。 mongod命令用于在容器启动后启动mongo进程。

将mongodb Dockerfile更改为以下内容：

FROM mongo:3.4
MAINTAINER Bill

创建用于撰写的mongodb容器时出错
