Rancher部署日志

我是靠谱客的博主温婉翅膀，最近开发中收集的这篇文章主要介绍Rancher部署日志，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

部署Rancher，建议单独部署在一台机器上，和集群分离

前面端口是宿主机端口后面端口是容器端口

docker run -d --restart=unless-stopped 
  -p 80:80 -p 443:443 
  -v /data/rancher:/var/lib/rancher 
  rancher/rancher:latest

创建集群，编辑集群配置文件，设置资源预留和限制

kubelet:
  extra_args:
    enforce-node-allocatable: pods
    kube-reserved: memory=2Gi
    system-reserved: memory=300Mi

预先按照open-iscsi

yum install iscsi-initiator-utils

在系统设置里把xip.io（用的人太多，不稳定）替换成 nip.io
在这里插入图片描述
配置kubectl

curl -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl
chmod +x ./kubectl
sudo mv ./kubectl /usr/local/bin/kubectl

从Rancher的Cluster界面下载KubeConfigFile

mkdir ~/.kube
vim ~/.kube/config
kubectl cluster-info

常用kubectl命令

清除kafka service
helm del --purge kafka
查看服务状态
kubectl get pod -n kafka -o wide
查看单独pod
kubectl describe pod -n kafka kafka-0

部署helm

curl https://raw.githubusercontent.com/kubernetes/helm/master/scripts/get > get_helm.sh
chmod 755 get_helm.sh
./get_helm.sh
helm init --upgrade -i registry.cn-hangzhou.aliyuncs.com/google_containers/tiller:v2.16.0
 
helm list
 
#如果报错，修复
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"}}}}'    
helm init --service-account tiller --upgrade -i registry.cn-hangzhou.aliyuncs.com/google_containers/tiller:v2.16.0
 
# 添加国内源
helm repo add stable https://burdenbear.github.io/kube-charts-mirror/
helm repo update

helm直接部署服务

helm install --name kong --set admin.useTLS=false,admin.servicePort=8001,admin.containerPort=8001,proxy.useTLS=false,proxy.servicePort=8000,proxy.containerPort=8000,livenessProbe.httpGet.scheme=HTTP,readinessProbe.httpGet.scheme=HTTP stable/kong

彻底删除Rancher

docker rm -f $(sudo docker ps -aq);
docker volume rm $(sudo docker volume ls -q);
 
rm -rf /etc/ceph 
       /etc/cni 
       /etc/kubernetes 
       /opt/cni 
       /opt/rke 
       /run/secrets/kubernetes.io 
       /run/calico 
       /run/flannel 
       /var/lib/calico 
       /var/lib/etcd 
       /var/lib/cni 
       /var/lib/kubelet 
       /var/lib/rancher/rke/log 
       /var/log/containers 
       /var/log/pods 
       /var/run/calico
 
for mount in $(mount | grep tmpfs | grep '/var/lib/kubelet' | awk '{ print $3 }') /var/lib/kubelet /var/lib/rancher; do umount $mount; done
 
rm -f /var/lib/containerd/io.containerd.metadata.v1.bolt/meta.db
sudo systemctl restart containerd
sudo systemctl restart docker
 
IPTABLES="/sbin/iptables"
cat /proc/net/ip_tables_names | while read table; do
  $IPTABLES -t $table -L -n | while read c chain rest; do
      if test "X$c" = "XChain" ; then
        $IPTABLES -t $table -F $chain
      fi
  done
  $IPTABLES -t $table -X
done
 
rm -rf /data/docker_data/rancher/
 
 
systemctl restart docker
