docker - 通过 docker-compose 启动 spring 配置服务器时的 503 状态

问题描述

我已经使用 spring boot 创建了演示配置服务器。它工作正常。 $ curl GET http://localhost:9090/actuator/health curl: (6) Could not resolve host: GET {"status":"UP"}% 我用作父项目

    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.3.RELEASE</version>

依赖项：

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-actuator</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-config-server</artifactId>
        <version>2.0.0.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
</dependencies>

下一步是通过 docker 包装服务。Dockerfile是：

FROM java:8-jre
VOLUME /tmp
ADD target/*.jar app.jar
ENV JAVA_OPTS="-XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode"
ENTRYPOINT java $JAVA_OPTS -Djava.security.egd=file:/dev/./urandom -jar /app.jar
EXPOSE 9090

创建独立的 docker 映像并启动容器，它按预期工作：

$ docker build .
>> ... <imageName>
$ docker run -p 9090:9090 <imageName>

创建docker-compose.yml：

version: '3.3'
services:
  config-server:
    build: config-server
    ports:
     - "9090:9090"
    expose:
     - "9090"
    networks:
     - "my-network"

networks:
  my-network:

启动和检查结果：

$ docker-compose up -d
$ curl GET http://localhost:9090/actuator/health
curl: (6) Could not resolve host: GET
{"status":"DOWN"}%

日志跟踪看起来不错：

知道如何修复启动的服务的健康状态docker-compose吗？

标签： dockerspring-bootdocker-composehttp-status-code-503configserver

解决方案

每次我启动容器时，它们都会成功创建。在开始新的之前，它们也被直接成功删除。上次我使用指令：

docker-compose down

docker-compose以自动方式删除由管理的容器。

这似乎很清楚。

...但！问题出在已经创建的图像中。并且图像没有更新。为了确认我的假设，我删除了相应的图像，并且每件事都已修复。为了以自动方式进行，我检测到了docker-compose其他有用的标志，我现在使用：

docker-compose down --rmi local
  • --rmi意味着删除所有基于容器的图像。
  • local仅删除该字段未设置自定义标签的image图像（通常情况下它是非 Internet 加载的图像）。
