在 minikube 上部署时出现 ImagePulloff 错误

Question

嘿，所以我试图在 minikube 上部署我的第一个简单的 web 应用程序，但这个 Imagepulloff 错误不断出现在 pod 中。 是的，我已经检查了几次 Image,tag 的名称； 这是日志和 yml 文件。

如果有人对此有所了解，请提供帮助。

Answer 1

访问容器注册表或用于图像的注册表的能力似乎是一个问题。 您可以尝试从节点手动拉取图像吗？

Answer 2

我认为您的互联网连接速度很慢。 拉取镜像的超时时间为120秒，因此 kubectl 无法在120秒内拉取镜像。

首先，通过Docker拉取镜像

docker image pull ayushftw/nodeapp1:latest

然后将下载的镜像加载到minikube

minikube image load ayushftw/nodeapp1:latest

然后一切都会工作，因为现在 kubectl 将使用本地存储的图像。
