无法检索Ignite Pod IP地址 [英] Failed to retrieve Ignite pods IP addresses
问题描述
我正在尝试使用Google Kubernetes Engine运行apache ignite集群.
I am trying to run apache ignite cluster using Google Kubernetes Engine.
遵循本教程之后,这里是一些 yaml 文件.
After following the tutorial here are some yaml files.
首先,我创建一个服务- ignite-service.yaml
First I create a service - ignite-service.yaml
apiVersion: v1
kind: Service
metadata:
# Name of Ignite Service used by Kubernetes IP finder.
# The name must be equal to TcpDiscoveryKubernetesIpFinder.serviceName.
name: ignite
namespace: default
spec:
clusterIP: None # custom value.
ports:
- port: 9042 # custom value.
selector:
# Must be equal to one of the labels set in Ignite pods'
# deployement configuration.
app: ignite
kubectl create -f ignite-service.yaml
kubectl create -f ignite-service.yaml
第二,我为我的ignite节点 ignite-deployment.yaml
Second, I create a deployment for my ignite nodes ignite-deployment.yaml
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
# Custom Ignite cluster's name.
name: ignite-cluster
spec:
# A number of Ignite pods to be started by Kubernetes initially.
replicas: 2
template:
metadata:
labels:
app: ignite
spec:
containers:
# Custom Ignite pod name.
- name: ignite-node
image: apacheignite/ignite:2.4.0
env:
- name: OPTION_LIBS
value: ignite-kubernetes
- name: CONFIG_URI
value: https://raw.githubusercontent.com/apache/ignite/master/modules/kubernetes/config/example-kube.xml
ports:
# Ports to open.
# Might be optional depending on your Kubernetes environment.
- containerPort: 11211 # REST port number.
- containerPort: 47100 # communication SPI port number.
- containerPort: 47500 # discovery SPI port number.
- containerPort: 49112 # JMX port number.
- containerPort: 10800 # SQL port number.
kubectl create -f ignite-deployment.yaml
kubectl create -f ignite-deployment.yaml
此后,我检查在我的情况下正在运行的Pod的状态.但是,当我检查任何吊舱的日志时,会出现以下错误,
After that I check status of my pods which are running in my case. However when I check logs for any of my pod, I get the following error,
java.io.IOException: Server returned HTTP response code: 403 for URL: https://kubernetes.default.svc.cluster.local:443/api/v1/namespaces/default/endpoints/ignite
我尝试过的事情:-
- 我关注了这个链接使集群工作.但是在第4步中,当我运行守护程序yaml文件时,出现以下错误
- I followed this link to make my cluster work. But in step 4, when I run the daemon yaml file, I get the following error
error: error validating "daemon.yaml": error validating data: ValidationError(DaemonSet.spec.template.spec): missing required field "containers" in io.k8s.api.core.v1.PodSpec; if you choose to ignore these errors, turn validation off with --validate=false
有人可以指出我在这里可能犯的错误吗?
Can anybody point me to my mistake which I might be doing here?
谢谢.
推荐答案
步骤1:kubectl apply -f ignite-service.yaml
(带有您问题中的文件)
Step 1: kubectl apply -f ignite-service.yaml
(with the file in your question)
第2步:kubectl apply -f ignite-rbac.yaml
ignite-rbac.yaml是这样的:
ignite-rbac.yaml is like this:
apiVersion: v1
kind: ServiceAccount
metadata:
name: ignite
namespace: default
---
apiVersion: rbac.authorization.k8s.io/v1
kind: Role
metadata:
name: ignite-endpoint-access
namespace: default
labels:
app: ignite
rules:
- apiGroups: [""]
resources: ["endpoints"]
resourceNames: ["ignite"]
verbs: ["get"]
---
apiVersion: rbac.authorization.k8s.io/v1
kind: RoleBinding
metadata:
name: ignite-role-binding
namespace: default
labels:
app: ignite
subjects:
- kind: ServiceAccount
name: ignite
roleRef:
kind: Role
name: ignite-endpoint-access
apiGroup: rbac.authorization.k8s.io
第3步:kubectl apply -f ignite-deployment.yaml
(非常类似于您的文件,我只添加了一行,serviceAccount: ignite
:
Step 3: kubectl apply -f ignite-deployment.yaml
(very similar to your file, I've only added one line, serviceAccount: ignite
:
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
# Custom Ignite cluster's name.
name: ignite-cluster
namespace: default
spec:
# A number of Ignite pods to be started by Kubernetes initially.
replicas: 2
template:
metadata:
labels:
app: ignite
spec:
serviceAccount: ignite ## Added line
containers:
# Custom Ignite pod name.
- name: ignite-node
image: apacheignite/ignite:2.4.0
env:
- name: OPTION_LIBS
value: ignite-kubernetes
- name: CONFIG_URI
value: https://raw.githubusercontent.com/apache/ignite/master/modules/kubernetes/config/example-kube.xml
ports:
# Ports to open.
# Might be optional depending on your Kubernetes environment.
- containerPort: 11211 # REST port number.
- containerPort: 47100 # communication SPI port number.
- containerPort: 47500 # discovery SPI port number.
- containerPort: 49112 # JMX port number.
- containerPort: 10800 # SQL port number.
这应该可以正常工作.我已经在pod(kubectl logs -f ignite-cluster-xx-yy
)的日志中找到了它,显示了两个Pod已成功定位到彼此:
This should work fine. I've got this in the logs of the pod (kubectl logs -f ignite-cluster-xx-yy
), showing the 2 Pods successfully locating each other:
[13:42:00] Ignite node started OK (id=f89698d6)
[13:42:00] Topology snapshot [ver=1, servers=1, clients=0, CPUs=1, offheap=0.72GB, heap=1.0GB]
[13:42:00] Data Regions Configured:

[13:42:01] Topology snapshot [ver=2, servers=2, clients=0, CPUs=2, offheap=1.4GB, heap=2.0GB]
[13:42:01] Data Regions Configured:
