运行容器的时候，发现一直处于ContainerCreating状态，悲了个催，刚入手就遇到了点麻烦，下面来讲讲如何查找问题及解决的
运行容器命令：
[root@master-149 ~]# kubectl run my-alpine --image=alpine --replicas=2 ping www.baidu.com
查看pods状态
1 [root@master-149 ~]# kubectl get pods2 NAME READY STATUS RESTARTS AGE3 my-alpine-2150523991-knzcx 0/1 ContainerCreating 0 6m4 my-alpine-2150523991-lmvv5 0/1 ContainerCreating 0 6m
一直处于ContainerCreating状态，开始查找原因
执行如下命令： 1 [root@master-149 ~]# kubectl describe pod my-alpine 2 Name: my-alpine-2150523991-knzcx 3 Namespace: default 4 Node: node-150/192.168.10.150 5 Start Time: Sat, 19 Nov 2016 18:20:52 +0800 6 Labels: pod-template-hash=2150523991,run=my-alpine 7 Status: Pending 8 IP: 9 Controllers: ReplicaSet/my-alpine-215052399110 Containers:11 my-alpine:12 Container ID: 13 Image: alpine14 Image ID: 15 Port: 16 Args:17 ping18 www.baidu.com19 QoS Tier:20 cpu: BestEffort21 memory: BestEffort22 State: Waiting23 Reason: ContainerCreating24 Ready: False25 Restart Count: 026 Environment Variables:27 Conditions:28 Type Status29 Ready False 30 No volumes.31 Events:32 FirstSeen LastSeen Count From SubobjectPath Type Reason Message33 --------- -------- ----- ---- ------------- -------- ------ -------34 7m 7m 1 {default-scheduler } Normal Scheduled Successfully assigned my-alpine-2150523991-knzcx to node-15035 6m 6m 1 {kubelet node-150} Warning FailedSync Error syncing pod, skipping: failed to "StartContainer" for "POD" with ErrImagePull: "image pull failed for gcr.io/google_containers/pause:2.0, this may be because there are no credentials on this request. details: (unable to ping registry endpoint https://gcr.io/v0/\nv2 ping attempt failed with error: Get https://gcr.io/v2/: dial tcp 64.233.189.82:443: getsockopt: connection refused\n v1 ping attempt failed with error: Get https://gcr.io/v1/_ping: dial tcp 64.233.189.82:443: getsockopt: connection refused)"36 37 4m 47s 3 {kubelet node-150} Warning FailedSync Error syncing pod, skipping: failed to "StartContainer" for "POD" with ErrImagePull: "image pull failed for gcr.io/google_containers/pause:2.0, this may be because there are no credentials on this request. details: (unable to ping registry endpoint https://gcr.io/v0/\nv2 ping attempt failed with error: Get https://gcr.io/v2/: dial tcp 74.125.204.82:443: getsockopt: connection refused\n v1 ping attempt failed with error: Get https://gcr.io/v1/_ping: dial tcp 74.125.204.82:443: getsockopt: connection refused)"38 39 4m 8s 6 {kubelet node-150} Warning FailedSync Error syncing pod, skipping: failed to "StartContainer" for "POD" with ImagePullBackOff: "Back-off pulling image \"gcr.io/google_containers/pause:2.0\""40 41 42 Name: my-alpine-2150523991-lmvv543 Namespace: default44 Node: node-150/192.168.10.15045 Start Time: Sat, 19 Nov 2016 18:20:52 +080046 Labels: pod-template-hash=2150523991,run=my-alpine47 Status: Pending48 IP: 49 Controllers: ReplicaSet/my-alpine-215052399150 Containers:51 my-alpine:52 Container ID: 53 Image: alpine54 Image ID: 55 Port: 56 Args:57 ping58 www.baidu.com59 QoS Tier:60 cpu: BestEffort61 memory: BestEffort62 State: Waiting63 Reason: ContainerCreating64 Ready: False65 Restart Count: 066 Environment Variables:67 Conditions:68 Type Status69 Ready False 70 No volumes.71 Events:72 FirstSeen LastSeen Count From SubobjectPath Type Reason Message73 --------- -------- ----- ---- ------------- -------- ------ -------74 7m 7m 1 {default-scheduler } Normal Scheduled Successfully assigned my-alpine-2150523991-lmvv5 to node-15075 5m 1m 3 {kubelet node-150} Warning FailedSync Error syncing pod, skipping: failed to "StartContainer" for "POD" with ErrImagePull: "image pull failed for gcr.io/google_containers/pause:2.0, this may be because there are no credentials on this request. details: (unable to ping registry endpoint https://gcr.io/v0/\nv2 ping attempt failed with error: Get https://gcr.io/v2/: dial tcp 74.125.204.82:443: getsockopt: connection refused\n v1 ping attempt failed with error: Get https://gcr.io/v1/_ping: dial tcp 74.125.204.82:443: getsockopt: connection refused)"76 77 3m 1m 4 {kubelet node-150} Warning FailedSync Error syncing pod, skipping: failed to "StartContainer" for "POD" with ImagePullBackOff: "Back-off pulling image \"gcr.io/google_containers/pause:2.0\""78 其中：79 80 Error syncing pod, skipping: failed to "StartContainer" for "POD" with ErrImagePull: "image pull failed for gcr.io/google_containers/pause:2.0, this may be because there are no credentials on this request. details: (unable to ping registry endpoint https://gcr.io/v0/\nv2 ping attempt failed with error: Get https://gcr.io/v2/: dial tcp 74.125.204.82:443: getsockopt: connection refused\n v1 ping attempt failed with error: Get https://gcr.io/v1/_ping: dial tcp 74.125.204.82:443: getsockopt: connection refused)
不难看出，
有如下解决办法：-
- FQ
- 修改hosts文件（这里我用的是“61.91.161.217 gcr.io”，但是可能会失效）
- 从其他源下载容器“pause:2.0”，然后打tag为“
