docker初体验:Docker部署SpringCloud项目eureka-server
Docker部署SpringCloud项目eureka-server
1 创建eureka-server工程
创建父工程cloud-demo,其pom.xml如下:
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.0.3.RELEASE</version> <relativePath/> </parent> <groupId>top.flygrk.ishare</groupId> <artifactId>cloud-demo</artifactId> <packaging>pom</packaging> <version>1.0-SNAPSHOT</version> <modules> <module>cloud-eureka-server</module> </modules> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> <spring-cloud.version>Finchley.RELEASE</spring-cloud.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> </dependencies> <dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-dependencies</artifactId> <version>${spring-cloud.version}</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
创建cloud-eureka-server模块,其格式如下:
pom.xml配置如下:
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <parent> <artifactId>cloud-demo</artifactId> <groupId>top.flygrk.ishare</groupId> <version>1.0-SNAPSHOT</version> </parent> <modelVersion>4.0.0</modelVersion> <artifactId>cloud-eureka-server</artifactId> <version>1.0-SNAPSHOT</version> <packaging>jar</packaging> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId> </dependency> </dependencies> <build> <finalName>eureka-server</finalName> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> <!-- tag::plugin[] --> <plugin> <groupId>com.spotify</groupId> <artifactId>docker-maven-plugin</artifactId> <version>0.4.13</version> <configuration> <imageName>/test/${project.artifactId}</imageName> <dockerDirectory>src/main/docker</dockerDirectory> <resources> <resource> <targetPath>/</targetPath> <directory>${project.build.directory}</directory> <include>${project.build.finalName}.jar</include> </resource> </resources> </configuration> </plugin> <!-- end::plugin[] --> </plugins> </build> </project>
2 eureka-server工程打包
使用maven对cloud-eureka-server模块打包,结果如下:
3 上传eureka-server.jar到服务器
上传eureka-server.jar到服务器路径/app/eureka-server:
4 编写Dockerfile文件
编写Dockerfile内容如下:
FROM java:8 VOLUME /tmp ADD eureka-server.jar app.jar EXPOSE 8761 ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]
5 打包eureka-server镜像
在/app/eureka-server目录下,执行如下命令进行docker镜像打包:
docker build -t eureka_v1.0.0 .
6 查看docker镜像
查看系统上的docker镜像,使用docker images
命令:
7 运行eurake镜像
使用下面的命令启动eureka镜像:
docker run -d --name eureka-server -p 8761:8761 c4bfd23fe99d
8 查看docker镜像运行情况
使用docker ps
查看docker镜像运行情况:
docker ps -a
8 查看docker eureka-server日志
使用下面的命令查看eureka-server日志:
docker logs --since 2019-12-18T09:50:15 eureka-server
