Error: error installing: the server could not find the requested resource
For more than v1.16.0 version Kubernetes, there may be encountered Error: error installing: the server could not find the requested resource error. This is due to extensions / v1beta1 has been replaced apps / v1. I believe in the released version 2.15 or 3, you should not encounter this problem. Or ecological reasons for relatively slow.
The solution is to use a statement like installation
helm init -i registry.cn-hangzhou.aliyuncs.com/google_containers/tiller:v2.14.3 --stable-repo-url http://mirror.azure.cn/kubernetes/charts/ --service-account tiller --override spec.selector.matchLabels.'name'='tiller',spec.selector.matchLabels.'app'='helm' --output yaml | sed 's@apiVersion: extensions/v1beta1@apiVersion: apps/v1@' | kubectl apply -f -
Provided --tiller-image --service-account parameters mounted helm
Check is not installed successfully
kubectl get pods -n kube-system | grep tiller
root@rancherk8sm1:~# helm version
Client: &version.Version{SemVer:"v2.12.1", GitCommit:"02a47c7249b1fc6d8fd3b94e6b4babf9d818144e", GitTreeState:"clean"}

Replace repo Ali mirror, note that the above command has been done this far, so I do not do it. Here is a case not yet replaced repo and repo introduction of how to replace.

1. Install the client Helm
One way:
public cloud environment can use the official script to install a key to install, just execute the following commands:
curl https://raw.githubusercontent.com/helm/helm/master/scripts/get |bash
Second way:
within the network environment can manually download and install, download address: https: //github.com/kubernetes/helm/releases
tar -zxvf helm-2.14.1.tar.gz
mv helm-2.14.1/helm /usr/local/bin/helm
Execute command to verify the helm version:
can only view the version of the client, the server has not been installed
[root@master1 helm]# helm version
Client: &version.Version{SemVer:"v2.14.1", GitCommit:"5270352a09c7e8b6e8c9593002a73535276507c0", GitTreeState:"clean"}
Error: could not find a ready tiller pod
bash command to install the helm of completion script:
helm completion bash > .hermrc ;echo "source .helmrc" >> .bashrc
2. Install the server Tiller
Under normal circumstances helm init to perform,
but in 1.16.0 and later versions kubernetes execution was reported the following error:
helm init
$HELM_HOME has been configured at /root/.helm.
Error: error installing: the server could not find the requested resource
The reason is because apiversion the deployment after 1.16.0 endpoint changes need to be processed as follows:
Output tiller definition files
> helm init --output yaml > tiller.yaml
#修改定义文件 apiVersion改为apps/v1,并新增selector信息 如下：
> vim tiller.yaml
---
apiVersion: apps/v1
kind: Deployment
metadata:
creationTimestamp: null
labels:
app: helm
name: tiller
name: tiller-deploy
namespace: kube-system
spec:
replicas: 1
strategy: {}
selector:
matchLabels:
app: helm
name: tiller
...
#修改后执行定义文件
> kubectl apply -f tiller.yaml
After performed using helm version and found a server has been installed successfully:
> helm version
Client: &version.Version{SemVer:"v2.14.1", GitCommit:"5270352a09c7e8b6e8c9593002a73535276507c0", GitTreeState:"clean"}
Server: &version.Version{SemVer:"v2.14.1", GitCommit:"5270352a09c7e8b6e8c9593002a73535276507c0", GitTreeState:"clean"}
Execution helm list found still being given as follows:
> helm list
Error: configmaps is forbidden: User "system:serviceaccount:kube-system:default" cannot list resource "configmaps" in API group "" in the namespace "kube-system"
Execute the following command:
# 在kube-system命名空间中创建tiller账户
kubectl create serviceaccount --namespace kube-system tiller
# 创建角色并授予cluster-admin权限
kubectl create clusterrolebinding tiller-cluster-rule --clusterrole=cluster-admin --serviceaccount=kube-system:tiller
#使用 kubectl patch 更新 API 对象
kubectl patch deploy --namespace kube-system tiller-deploy -p '{"spec":{"template":{"spec":{"serviceAccount":"tiller"}}}}'
helm init --service-account tiller --upgrade
# 指定账户进行初始化，别忘了还要指定tiller镜像哦
helm init --service-account tiller --override spec.selector.matchLabels.'name'='tiller',spec.selector.matchLabels.'app'='helm' --output yaml | sed 's@apiVersion: extensions/v1beta1@apiVersion: apps/v1@' | kubectl apply -f -
After performing tiller successful installation.
Note: For this error Error: error installing: the server could not find the requested resource
can directly use the following command to solve, it will not report rbacx related mistake.
helm init --service-account tiller --override spec.selector.matchLabels.'name'='tiller',spec.selector.matchLabels.'app'='helm' --output yaml | sed 's@apiVersion: extensions/v1beta1@apiVersion: apps/v1@' | kubectl apply -f -
