在 minikube 上部署時出現 ImagePulloff 錯誤

Question

嘿，所以我試圖在 minikube 上部署我的第一個簡單的 web 應用程序，但這個 Imagepulloff 錯誤不斷出現在 pod 中。 是的，我已經檢查了幾次 Image,tag 的名稱； 這是日志和 yml 文件。

如果有人對此有所了解，請提供幫助。

Answer 1

訪問容器注冊表或用於圖像的注冊表的能力似乎是一個問題。 您可以嘗試從節點手動拉取圖像嗎？

Answer 2

我認為您的互聯網連接速度很慢。 拉取鏡像的超時時間為120秒，因此 kubectl 無法在120秒內拉取鏡像。

首先，通過Docker拉取鏡像

docker image pull ayushftw/nodeapp1:latest

然后將下載的鏡像加載到minikube

minikube image load ayushftw/nodeapp1:latest

然后一切都會工作，因為現在 kubectl 將使用本地存儲的圖像。
