我尝试使用秘密从 ACR 中提取图像,但我做不到。
我使用 azure cli 命令创建了资源:
az login
az provider register -n Microsoft.Network
az provider register -n Microsoft.Storage
az provider register -n Microsoft.Compute
az provider register -n Microsoft.ContainerService
az group create --name aksGroup --location westeurope
az aks create --resource-group aksGroup --name aksCluster --node-count 1 --generate-ssh-keys -k 1.9.2
az aks get-credentials --resource-group aksGroup --name aksCluster
az acr create --resource-group aksGroup --name aksClusterRegistry --sku Basic --admin-enabled true
之后,我登录并成功推送图像以从本地计算机创建 ACR。
docker login aksclusterregistry.azurecr.io
docker tag jetty aksclusterregistry.azurecr.io/jetty
docker push aksclusterregistry.azurecr.io/jetty
下一步是创建一个秘密:
kubectl create secret docker-registry secret --docker-server=aksclusterregistry.azurecr.io --docker-username=aksClusterRegistry --docker-password=<Password from tab ACR/Access Keys> --docker-email=some@email.com
最终我尝试使用来自 ACR 的图像创建 pod:
#pod.yml
apiVersion: v1
kind: Pod
metadata:
name: jetty
spec:
containers:
- name: jetty
image: aksclusterregistry.azurecr.io/jetty
imagePullSecrets:
- name: secret
kubectl create -f pod.yml
结果我有一个状态为 ImagePullBackOff 的 pod:
>kubectl get pods
NAME READY STATUS RESTARTS AGE
jetty 0/1 ImagePullBackOff 0 1m
> kubectl describe pod jetty
Events:

怎么了?为什么秘密方法不起作用?请不要建议我使用服务负责人,因为我想了解为什么这种方法不起作用。我认为它必须工作。
