微服务架构和 Docker 中的 JHipster 应用程序出现奇怪错误

Question

我已经用 JHipster 5.0.1 版本生成了一个应用程序。该应用有 4 个组件：

• 用于用户记账和授权的 UAA 应用
• JHipster Registry 应用程序
• 网关应用
• 一个简单的微服务

我已按照文档中的所有步骤进行操作，包括创建 docker compose 文件的步骤。但是，当我想运行 docker-compose up 时，我的自定义组件的拉取权限出现了一些错误。

这是日志

compose.cli.verbose_proxy.proxy_callable: docker inspect_image http://localhost:None“GET /v1.22/images/chipgames/json HTTP/1.1”404 60 compose.service.pull: 拉出chipgames-app (chipgames:)... compose.cli.verbose_proxy.proxy_callable: docker pull https://index.docker.io/v1/”的身份验证条目 docker.auth.get_config_header：找到授权配置 urllib3.connectionpool._make_request: http://localhost:None "POST /v1.22/images/create?tag=latest&fromImage=chipgames HTTP/1.1" 404 91

我正在运行 docker 服务，我也在 docker hub 中创建了一个存储库，但我不明白错误。

编辑：

这是我的 docker-compose.yml

Answer 1

我猜你有私有存储库。 如果它是私有存储库，则 pull 需要 docker 登录凭据。 请点击此链接：https://ropenscilabs.github.io/r-docker-tutorial/04-Dockerhub.html

这样你就可以拉取 Docker 镜像了。

Answer 2

问题是 docker 正在寻找您的图像 appuaa、chipagames。这是因为您没有在本地构建它们，而 docker 正在寻找已知的存储库，例如 hub.docker，但没有成功。

您应该使用

构建您的应用程序

./mvnw -Pprod package dockerfile:build

或

./gradlew -Pprod build buildDocker

然后再次尝试docker-compose up
