标签:部署 consul resources server 110s helm k8s Pending
这里我们使用helm进行部署
1.下载helm
wget https://get.helm.sh/helm-v3.9.0-linux-amd64.tar.gz
2.配helm的repo源
helm repo add hashicorp https://helm.releases.hashicorp.com
3.编写consul的config.yml文件
global: name: consul # Configure your Consul servers in this section. server: # Specify three servers that wait until all are healthy to bootstrap the Consul cluster. replicas: 3 # Specify the resources that servers request for placement. These values will serve a large environment. storage: '10Gi' #storageClass: "nfs-sc" #如配置了SC则将这个打开 securityContext: # 服务器 Pod 的安全上下文,以 root 用户运行 fsGroup: 2000 runAsGroup: 2000 runAsNonRoot: false runAsUser: 0 resources: requests: memory: '512Mi' cpu: '0.5' limits: memory: '1Gi' cpu: '1' # Configure Consul clients in this section client: # Specify the resources that clients request for deployment. resources: requests: memory: '256Mi' cpu: '0.5' limits: memory: '512Gi' cpu: '1' # Enable and configure the Consul UI. ui: enabled: true
4.开始安装consul
helm install consul hashicorp/consul --values config.yaml --create-namespace --namespace consul --version "0.43.0"
5.如果集群没有配置SC则会发现POD一直处于pending的情况
[root@master1 consul]# kubectl get po -n consul NAME READY STATUS RESTARTS AGE consul-client-bjzvn 0/1 Running 0 110s consul-client-dlr7n 0/1 Running 0 110s consul-client-rkdtg 0/1 Running 0 110s consul-server-0 0/1 Pending 0 110s consul-server-1 0/1 Pending 0 110s consul-server-2 0/1 Pending 0 110s [root@master1 consul]# kubectl get pvc -n consul NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGE data-consul-consul-server-0 Pending 2m16s data-consul-consul-server-1 Pending 2m16s data-consul-consul-server-2 Pending 2m16s 因为没有pv创建 [root@master1 consul]# kubectl get pv -n consul No resources found
出现上述情况则自己挂载好nfs创建pv就行
[root@master1 consul]# cat consul-pv.yaml apiVersion: v1 kind: PersistentVolume metadata: name: data-consul-consul-server-0 spec: capacity: storage: 10Gi volumeMode: Filesystem accessModes: - ReadWriteOnce persistentVolumeReclaimPolicy: Recycle nfs: path: /pvdata/consul0 server: 172.16.149.202 可以参考以上模板
如果有sc的同学则删掉helm部署在congfig.yaml文件上打开sc改为自己sc的名字即可
