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”

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)

How to use Docker Desktop? Docker Desktop is a tool for running Docker containers on local machines. The steps to use include: 1. Install Docker Desktop; 2. Start Docker Desktop; 3. Create Docker image (using Dockerfile); 4. Build Docker image (using docker build); 5. Run Docker container (using docker run).

Steps to create a Docker image: Write a Dockerfile that contains the build instructions. Build the image in the terminal, using the docker build command. Tag the image and assign names and tags using the docker tag command.

Troubleshooting steps for failed Docker image build: Check Dockerfile syntax and dependency version. Check if the build context contains the required source code and dependencies. View the build log for error details. Use the --target option to build a hierarchical phase to identify failure points. Make sure to use the latest version of Docker engine. Build the image with --t [image-name]:debug mode to debug the problem. Check disk space and make sure it is sufficient. Disable SELinux to prevent interference with the build process. Ask community platforms for help, provide Dockerfiles and build log descriptions for more specific suggestions.

To save the image in Docker, you can use the docker commit command to create a new image, containing the current state of the specified container, syntax: docker commit [Options] Container ID Image name. To save the image to the repository, you can use the docker push command, syntax: docker push image name [: tag]. To import saved images, you can use the docker pull command, syntax: docker pull image name [: tag].

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.

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).
