docker - 至少遇到一个无效签名

Question

我正在尝试使用 minikube 构建微服务镜像并将其部署到在我的开发机器上运行的单节点 Kubernetes 集群。我正在使用 Google 的云原生微服务演示应用程序 Online Boutique 来了解 Kubernetes、Istio 等技术的使用。

链接到 github 存储库:microservices-demo

在遵循安装过程的同时，运行命令 skaffold run要构建和部署我的应用程序，我收到了一些错误:

Step 10/11 : RUN apt-get -qq update     && apt-get install -y --no-install-recommends         curl

我在尝试构建 loadgenerator 时收到这些错误。
我该如何解决这个问题？

Answer 1

遇到这些错误的原因有几个:

现有缓存和/或磁盘空间可能存在问题。为了修复它，您需要通过执行以下命令清除 APT 缓存:sudo apt-get clean和 sudo apt-get update .

现有的 docker 镜像也是如此。执行:docker image prune -f和 docker container prune -f以删除未使用的数据并释放磁盘空间。

如果不关心安全风险，可以尝试运行apt-get命令与 --allow-unauthenticated或 --allow-insecure-repositories旗帜。根据docs :

Ignore if packages can't be authenticated and don't prompt about it. This can be useful while working with local repositories, but is a huge security risk if data authenticity isn't ensured in another way by the user itself.

如果这有帮助，请告诉我。
