Question

我正在尝试部署我的k8s集群。但是当我这样做时，它无法拉出图像。这是我运行kubectl describe pods时得到的信息：

  Type     Reason      Age               From                   Message

  Normal   Pulling     9m (x3 over 2h)   kubelet, dc9ebacs9000  pulling image "tlk8s.azurecr.io/devicecloudwebapi:v1"

当我看着单个吊舱时，这就是我得到的：

Error from server (BadRequest): container "tl-api" in pod "tl-api-3363368743-d7kjq" is waiting to start: image can't be pulled

这是我的YAML文件：

我的docker映像结果：

首先，我将仔细检查您是否通过cli在正确的注册表中登录了docker。

类似docker login <REGISTRY_NAME> -u <CLIENT_ID>

您将要确保已创建了一个k8s机密并将其绑定到注册表。如果您还没有这样做，请检查this post。我看到您的Yaml指定了一个秘密，但这也在注册表中配置了吗？
