[英]kubectl get pods ErrImagePull
我正在与Kubernetes战斗。 我GOOGLE了很多,看了几个答案,如这一个 -例如-但似乎无法得到它的工作。
我创建了一个docker容器并推送到本地注册表:
sudo docker run -d -p 5000:5000 --name registry registry:2
sudo docker tag i-a/i-a:latest localhost:5000/i-a
sudo docker push localhost:5000/i-a
最后一条命令给出:
The push refers to a repository [localhost:5000/i-a]
e0a33c56cca0: Pushed
54ab83ede54d: Pushed
f5a58f369605: Pushed
cd7100a72410: Pushed
latest: digest: sha256:0f30cdf6b4a4e0e382a6cae50c1325103c3b987d9e51c42edea2244a82ae1331 size: 1164
做sudo docker pull localhost:5000/ia
给出了:
Using default tag: latest
latest: Pulling from i-a
Digest: sha256:0f30cdf6b4a4e0e382a6cae50c1325103c3b987d9e51c42edea2244a82ae1331
Status: Image is up to date for localhost:5000/i-a:latest
配置文件ia.yaml:

当我执行sudo kubectl get pods --all-namespaces
我得到:
...
default i-a-3400848339-0x6c9 0/1 ImagePullBackOff 0 13m
default i-a-3400848339-7ltp1 0/1 ImagePullBackOff 0 13m
default i-a-3400848339-wv092 0/1 ImagePullBackOff 0 13m
ImagePullBackOff
变为ErrImagePull
。
当我运行kubectl describe pod ia-3400848339-0x6c9
出现错误Failed to pull image "localhost:5000/ia": Error while pulling image: Get http://localhost:5000/v1/repositories/ia/images: dial tcp 127.0.0.1:5000: getsockopt: connection refused

我不确定下一步要去哪里...(浏览到http:// localhost:5000 / v1 / repositories / ia / images时得到404)
尝试:
spec:
containers:
- image: localhost:5000/i-a
imagePullPolicy: Never
name: i-a
ports:
- containerPort: 8090
dnsPolicy: ClusterFirst
restartPolicy: Always
