Kubernetes

1，Helm 介绍

核心术语：
- Chart：一个helm程序包
- Repository：Charts仓库，https/http 服务器
- Release：特定的Chart部署与目标集群上的一个实例
- Chart -> Config -> Release
程序架构：
- Helm：客户端，管理本地的Chart仓库，管理Chart，与Tiller服务器交互，发送Chart，实现安装、查询、卸载等操作
- Tiller：服务端，接收helm发来的Charts与Config，合并生成 Release

2，Helm安装

Helm由两个组件组成：
- HelmClinet：客户端，拥有对Repository、Chart、Release等对象的管理能力。
- TillerServer：负责客户端指令和k8s集群之间的交互，根据Chart定义，生成和管理各种k8s的资源对象。

2.1 安装HelmClient

可以通过二进制文件或脚本方式进行安装。
下载最新版二进制文件：https://github.com/helm/helm/releases
本文下载 helm-v2.11.0 版本

wget https://storage.googleapis.com/kubernetes-helm/helm-v2.11.0-linux-amd64.tar.gz

解压

tar zxf helm-v2.11.0-linux-amd64.tar.gz

移动到 /usr/local/bin 下

cp linux-amd64/helm linux-amd64/tiller /usr/local/bin/

2.2 安装TillerServer

依赖包

yum -y install socat

所有节点下载tiller:v[helm-version]镜像，helm-version为上面helm的版本2.11.0

docker pull xiaoqshuo/tiller:v2.11.0

使用helm init安装tiller

[root@k8s-master01 ~]# helm init --tiller-image xiaoqshuo/tiller:v2.11.0

$HELM_HOME has been configured at /root/.helm.

Tiller (the Helm server-side component) has been installed into your Kubernetes Cluster.

Please note: by default, Tiller is deployed with an insecure 'allow unauthenticated users' policy.
To prevent this, run `helm init` with the --tiller-tls-verify flag.
For more information on securing your installation see: https://docs.helm.sh/using_helm/#securing-your-helm-installation
Happy Helming!

2.3 查看helm version及pod状态

[root@k8s-master01 opt]# helm version
Client: &version.Version{SemVer:"v2.11.0", GitCommit:"2e55dbe1fdb5fdb96b75ff144a339489417b146b", GitTreeState:"clean"}
Server: &version.Version{SemVer:"v2.11.0", GitCommit:"2e55dbe1fdb5fdb96b75ff144a339489417b146b", GitTreeState:"clean"}

[root@k8s-master01 opt]# kubectl get pod -n kube-system | grep tiller
tiller-deploy-84f64bdb87-w69rw          1/1     Running   0          88s

[root@k8s-master01 opt]# kubectl get pod,svc -n kube-system | grep tiller
pod/tiller-deploy-84f64bdb87-w69rw          1/1     Running   0          94s

service/tiller-deploy          ClusterIP   10.108.21.50     <none>        44134/TCP        95s

2.4 报错

# helm list
Error: configmaps is forbidden: User "system:serviceaccount:kube-system:default" cannot list resource "configmaps" in API group "" in the namespace "kube-system"

执行以下命令创建serviceaccount tiller并且给它集群管理权限

kubectl create serviceaccount --namespace kube-system tiller
kubectl create clusterrolebinding tiller-cluster-rule --clusterrole=cluster-admin --serviceaccount=kube-system:tiller
kubectl patch deploy --namespace kube-system tiller-deploy -p '{"spec":{"template":{"spec":{"serviceAccount":"tiller"}}}}'

2.5 离线部署tiller

下载tiller镜像

docker pull registry.cn-hangzhou.aliyuncs.com/google_containers/tiller:v2.11.0
docker tag registry.k8s.com:8888/tiller:v2.11.0
docker push registry.k8s.com:8888/tiller:v2.11.0

部署rabc权限tiller-rbac.yaml

$ cat tiller-rbac.yaml 
apiVersion: v1
kind: ServiceAccount
metadata:
  name: tiller
  namespace: kube-system
---
apiVersion: rbac.authorization.k8s.io/v1beta1
kind: ClusterRoleBinding
metadata:
  name: tiller
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
  - kind: ServiceAccount
    name: tiller
    namespace: kube-system

helm 初始化启动 tiller

helm init --upgrade --service-account tiller  --tiller-image registry.k8s.com:8888/tiller:v2.11.0 --stable-repo-url http://192.168.1.128/charts

备注：上面命令中的--stable-repo-url http://192.168.1.128/charts这个是我用nginx http做的，这儿下面放了一个文件index.yaml文件，可以从这儿下载到https://kubernetes-charts.storage.googleapis.com/index.yaml或https://kubernetes.oss-cn-hangzhou.aliyuncs.com/charts/index.yaml

3，harbor

3.1 安装 harbor

3.1.1 换 helm 源

查看 helm 源

[root@k8s-master01 ~]# helm repo list
NAME  	URL
stable	https://kubernetes-charts.storage.googleapis.com
local 	http://127.0.0.1:8879/charts

移除默认源以及本地源

[root@k8s-master01 ~]# helm repo remove stable
"stable" has been removed from your repositories

[root@k8s-master01 ~]# helm repo remove local
"local" has been removed from your repositories

添加 aliyun 源

[root@k8s-master01 ~]# helm repo add aliyun    https://kubernetes.oss-cn-hangzhou.aliyuncs.com/charts
"aliyun" has been added to your repositories

[root@k8s-master01 ~]# helm repo list
NAME  	URL
aliyun	https://kubernetes.oss-cn-hangzhou.aliyuncs.com/charts

3.1.2 下载harbor

checkout到0.3.0分支

git clone https://github.com/goharbor/harbor-helm.git

3.1.3 更改requirement.yam

[root@k8s-master01 harbor-helm]# cat requirements.yaml
dependencies:
- name: redis
  version: 1.1.15
  repository: https://kubernetes.oss-cn-hangzhou.aliyuncs.com/charts
  # repository: https://kubernetes-charts.storage.googleapis.com

3.1.4 下载依赖

[root@k8s-master01 harbor-helm]#  helm dependency update
Hang tight while we grab the latest from your chart repositories...
...Successfully got an update from the "aliyun" chart repository
Update Complete. ⎈Happy Helming!⎈

Downloading redis from repo https://kubernetes.oss-cn-hangzhou.aliyuncs.com/charts
Deleting outdated charts

3.1.5 所有节点下载相关镜像

docker pull goharbor/chartmuseum-photon:v0.7.1-v1.6.0
docker pull goharbor/harbor-adminserver:v1.6.0
docker pull goharbor/harbor-jobservice:v1.6.0
docker pull goharbor/harbor-ui:v1.6.0
docker pull goharbor/harbor-db:v1.6.0
docker pull goharbor/registry-photon:v2.6.2-v1.6.0

docker pull goharbor/notary-signer-photon:v0.5.1-v1.6.0
docker pull bitnami/redis:4.0.8-r2

3.1.6 更改 values.yaml

更改values.yaml所有的storageClass为storageClass: "gluster-heketi"

sed -i 's@# storageClass: "-"@storageClass: "gluster-heketi"@g' values.yaml

    volumes:
      data:
        storageClass: "gluster-heketi"
        accessMode: ReadWriteOnce
        size: 1Gi

修改values.yaml的redis默认配置，添加port至master

redis:
  # if external Redis is used, set "external.enabled" to "true"
  # and fill the connection informations in "external" section.
  # or the internal Redis will be used
  usePassword: false
  password: "changeit"
  cluster:
    enabled: false
  master:
    port: "6379"
    persistence:
      enabled: *persistence_enabled
      storageClass: "gluster-heketi"
      accessMode: ReadWriteOnce
      size: 1Gi

修改charts/redis-1.1.15.tgz 里面的redis下template下的svc的name: {{ template "redis.fullname" . }}-master

sed -i 's#name: {{ template "redis.fullname" . }}#name: {{ template "redis.fullname" . }}-master#g' redis/templates/svc.yaml

[root@k8s-master01 charts]# more !$
more redis/templates/svc.yaml
apiVersion: v1
kind: Service
metadata:
  name: {{ template "redis.fullname" . }}-master
  labels:
    app: {{ template "redis.fullname" . }}
    chart: "{{ .Chart.Name }}-{{ .Chart.Version }}"
    release: "{{ .Release.Name }}"
    heritage: "{{ .Release.Service }}"
  annotations:
{{- if .Values.service.annotations }}
{{ toYaml .Values.service.annotations | indent 4 }}
{{- end }}
{{- if .Values.metrics.enabled }}
{{ toYaml .Values.metrics.annotations | indent 4 }}
{{- end }}
spec:
  type: {{ .Values.serviceType }}
  {{ if eq .Values.serviceType "LoadBalancer" -}} {{ if .Values.service.loadBalancerIP -}}
  loadBalancerIP: {{ .Values.service.loadBalancerIP }}
  {{ end -}}
  {{- end -}}
  ports:
  - name: redis
    port: 6379
    targetPort: redis
  {{- if .Values.metrics.enabled }}
  - name: metrics
    port: 9121
    targetPort: metrics
  {{- end }}
  selector:
    app: {{ template "redis.fullname" . }}

删除原来的tgz包，重新打包

[root@k8s-master01 charts]# tar zcf redis-1.1.15.tgz redis/

注意修改相关存储空间的大小，比如registry。

3.1.7 安装harbor

helm install --name harbor-v1 .  --wait --timeout 1500 --debug --namespace harbor

[root@k8s-master01 harbor-helm]# helm install --name harbor-v1 .  --wait --timeout 1500 --debug --namespace harbor
[debug] Created tunnel using local port: '42156'

[debug] SERVER: "127.0.0.1:42156"

[debug] Original chart version: ""
[debug] CHART PATH: /opt/k8s-cluster/harbor-helm

Error: error unpacking redis-1.1.15.tgz.bak in harbor: chart metadata (Chart.yaml) missing

如果报forbidden的错误，需要创建serveraccount

kubectl create serviceaccount --namespace kube-system tiller

kubectl create clusterrolebinding tiller-cluster-rule --clusterrole=cluster-admin --serviceaccount=kube-system:tiller

kubectl patch deploy --namespace kube-system tiller-deploy -p '{"spec":{"template":{"spec":{"serviceAccount":"tiller"}}}}'

[root@k8s-master01 harbor-helm]# kubectl create serviceaccount --namespace kube-system tiller
serviceaccount/tiller created

[root@k8s-master01 harbor-helm]# kubectl create clusterrolebinding tiller-cluster-rule --clusterrole=cluster-admin --serviceaccount=kube-system:tiller
clusterrolebinding.rbac.authorization.k8s.io/tiller-cluster-rule created

[root@k8s-master01 harbor-helm]# kubectl patch deploy --namespace kube-system tiller-deploy -p '{"spec":{"template":{"spec":{"serviceAccount":"tiller"}}}}'
deployment.extensions/tiller-deploy patched

再次部署

[root@k8s-master01 harbor-helm]# helm install --name harbor-v1 .  --wait --timeout 1500 --debug --namespace harbor
[debug] Created tunnel using local port: '45170'

[debug] SERVER: "127.0.0.1:45170"

[debug] Original chart version: ""
[debug] CHART PATH: /opt/k8s-cluster/harbor-helm

[root@k8s-master01 harbor-helm]# docker tag busybox:1.27 core.harbor.domain/develop/busybox:1.27

上传

[root@k8s-master01 harbor-helm]# docker push core.harbor.domain/develop/busybox:1.27
The push refers to a repository [core.harbor.domain/develop/busybox]
0271b8eebde3: Pushed

4，总结

部署过程中遇到的问题：
- 1. 由于某种原因无法访问https://kubernetes-charts.storage.googleapis.com，也懒得FQ，就使用阿里的helm仓库。(如果FQ了，就没有以下问题)
- 1. 由于换成了阿里云的仓库，找不到源requirement.yaml中的redis版本，故修改阿里云仓库中有的redis。
- 1. 使用了GFS动态存储，持久化了Harbor，需要更改values.yaml和redis里面的values.yaml中的storageClass。
- 1. 阿里云仓库中的redis启用了密码验证，但是harbor chart的配置中未启用密码，所以干脆禁用了redis的密码。
- 1. 使用Helm部署完Harbor以后，jobservice和harbor-ui的pods不断重启，通过日志发现未能解析Redis的service，原因是harbor chart里面配置Redis的service是harbor-v1-redis-master，而通过helm dependency update下载的Redis Chart service配置的harbor-v1-redis，为了方便，直接改了redis的svc.yaml文件。
- 1. 更改完上述文件以后pods还是处于一直重启的状态，且报错：Failed to load and run worker pool: connect to redis server timeout: dial tcp 10.96.137.238:0: i/o timeout，发现Redis的地址+端口少了端口，最后经查证是harbor chart的values的redis配置port的参数，加上后重新部署即成功。
- 1. 由于Helm安装的harbor默认启用了https，故直接配置证书以提高安全性。
- 1. 将Harbor安装到k8s上，原作者推荐的是Helm安装，详情见：https://github.com/goharbor/harbor/blob/master/docs/kubernetes_deployment.md，文档见：https://github.com/goharbor/harbor-helm
- 1. 个人认为Harbor应该独立于k8s集群之外使用docker-compose单独部署（https://github.com/goharbor/harbor/blob/master/docs/installation_guide.md），这也是最常见的方式，我目前使用的是此种方式(此文档为第一次部署harbor到k8s,也为了介绍Helm)，而且便于维护及扩展，以及配置LDAP等都很方便。
- 1. Helm是非常强大的k8s包管理工具。
- 1. Harbor集成openLDAP点击
