Question

我正在尝试在Kubernetes清单中包含自己的私有Docker映像，但出现ImagePullBackOff错误。

我不确定是否已经： -为我的secrets使用了错误的数据 -在某处缺少命令 -使用某些特定名称或标签等错误的数据

该映像托管在Azure容器注册表（aka。ACR）上。

这是我遇到的错误...然后是我尝试执行的步骤。

Tests-MBP:k8s test$ clear && kubectl describe pod acounts-api-7fcc5d9bb-826ht

Tests-MBP:k8s test$

我已经创建了一个secret：

Tests-MacBook-Pro:k8s test$ kubectl get secrets
NAME                  TYPE                                  DATA   AGE
default-token-ffrhq   kubernetes.io/service-account-token   3      3d
hornet-acr-auth       kubernetes.io/dockerconfigjson        1      16h
Tests-MacBook-Pro:k8s test$

使用以下命令：

Tests-MacBook-Pro:k8s test$ kubectl create secret docker-registry hornet-acr-auth --docker-server <snip>.azurecr.io --docker-username 9858ae98-<snip> --docker-password 10abe15a-<snip> --docker-email a@b.com
secret/hornet-acr-auth created

并获取该用户名/密码，我followed these instructions并做到了...

Tests-MacBook-Pro:k8s test$ ./azure-credentials.sh 
Retrying role assignment creation: 1/36
Service principal ID: 9858ae98-<snip>
Service principal password: 10abe15a-<snip>

以及我的.sh脚本的前几行...

#!/bin/bash

ACR_NAME=<snip> // this is the name of the ACR (e.g. foo) .. NOT foo.azurecr.io
SERVICE_PRINCIPAL_NAME=acr-service-principal

...

最后..这就是我试图在我的deployment清单中创建.yaml的方式。...

apiVersion: apps/v1

  name: acounts-api
spec:
  selector:
    matchLabels:
      app: acounts-api

      labels:

      containers:
      - name: acounts-api
        image: hornet/accounts.api
        imagePullPolicy: Always
        ports:
        - containerPort: 80
          name: http
        - containerPort: 5301
          name: data-ingest
        env:
        - name: "RavenDb__ServerUrl"
          value: "http://ravendb-data-lb:5200"
---

是的，我已经确认存储库存在于ACR中。

图像hornet/accounts.api实际上看起来像是来自Docker Hub的图像，情况并非如此，对吗？

我猜您的图片名称应该是<snip>.azurecr.io/accounts.api还是<snip>.azurecr.io/hornet/accounts.api？
