How to develop Java 8 Spring Boot applications in Docker
首先,让我们检查一下docker-compose
文件:
version : '2' services: springappserver: build: context: . dockerfile: springapp.dockerfile ports: - "8080:8080" networks: - net-spring-db volumes: - .:/vol/development depends_on: - mysqldbserver mysqldbserver: build: context: . dockerfile: mysqldb.dockerfile ports: - "3306:3306" networks: - net-spring-db environment: mysql_database: testdb mysql_user: myuser mysql_password: mypassword mysql_root_password: myrootpassword container_name: mysqldbserver networks: net-spring-db: driver: bridge
我们在'net-spring-db'上分别有两台服务器。第一个名为'springappserver',并使用springapp.dockerfile
配置。第二个命名为mysqldbserver,并使用mysqldb.dockerfile
进行配置。
现在,让我们看一下springapp.dockerfile:
# # java 1.8 & maven dockerfile # # # pull base image. from java:8 # maintainer maintainer dursun koc "dursunkoc@gmail.com" # 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"]
docker文件配置docker镜像,该镜像继承自docker hub的java 8镜像 。在java 8镜像上,我安装了vim,wget,curl,maven,并设置了卷以便放置我现有的项目代码。最后,执行maven命令来运行我的应用程序。
现在让我们检查一下mysqldb.dockerfile:
from mysql/mysql-server maintainer dursun koc <dursunkoc@gmail.com> # copy the database initialize script: # contents of /docker-entrypoint-initdb.d are run on mysqld startup add mysql/ /docker-entrypoint-initdb.d/
docker文件配置docker镜像,该镜像继承自docker hub的mysql / mysql-server映像 。在mysql映像上,我放置了我的db-schema创建脚本,它们位于mysql文件夹中。我在这个文件夹中有一个sql文件 - data.sql - 以创建'person'表。
现在,我们看看应用程序结构。
我们的应用程序是从src / com / turkcell / softlab / application.java
文件开始的,我们唯一的controller是personcontroller(src / com / turkcell / softlab / controller / personcontroller.java)。
您可以使用简单的命令运行整个项目:
docker-compose up -d
测试时,请在本地计算机中使用以下两个命令:
• 创建新人:
curl -h “content-type:application / json” -x post -d “{\”first \“:\”mustafa \“,\”last \“:\”koç\“,\”dateofbirth \“381110400000 ,“placeofbirth”:\“erzincan \”}“ ”http://192.168.99.100:8080/people“
• 列出数据库中的现有人员:
curl -h “content-type:application / json” -x get “http://192.168.99.100:8080/people”

Four ways to exit Docker container: Use Ctrl D in the container terminal Enter exit command in the container terminal Use docker stop <container_name> Command Use docker kill <container_name> command in the host terminal (force exit)

Methods for copying files to external hosts in Docker: Use the docker cp command: Execute docker cp [Options] <Container Path> <Host Path>. Using data volumes: Create a directory on the host, and use the -v parameter to mount the directory into the container when creating the container to achieve bidirectional file synchronization.

How to restart the Docker container: get the container ID (docker ps); stop the container (docker stop <container_id>); start the container (docker start <container_id>); verify that the restart is successful (docker ps). Other methods: Docker Compose (docker-compose restart) or Docker API (see Docker documentation).

You can query the Docker container name by following the steps: List all containers (docker ps). Filter the container list (using the grep command). Gets the container name (located in the "NAMES" column).

The process of starting MySQL in Docker consists of the following steps: Pull the MySQL image to create and start the container, set the root user password, and map the port verification connection Create the database and the user grants all permissions to the database

Docker container startup steps: Pull the container image: Run "docker pull [mirror name]". Create a container: Use "docker create [options] [mirror name] [commands and parameters]". Start the container: Execute "docker start [Container name or ID]". Check container status: Verify that the container is running with "docker ps".

The steps to update a Docker image are as follows: Pull the latest image tag New image Delete the old image for a specific tag (optional) Restart the container (if needed)
