安装ilogtail
1.登陆可以控制K8S集群的中控机。编辑ilogtail的ConfigMap YAML。
$ vim alicloud-log-config.yaml
在Vim中粘贴如下内容并保存（注意，修改注释中提示的字段，7-11行）。
apiVersion: v1
kind: ConfigMap
metadata:
name: alibaba-log-configuration
namespace: kube-system
data:
log-project: "my-project" #修改为实际创建的project名称
log-endpoint: "cn-wulanchabu.log.aliyuncs.com" #修改为实际endpoint 改一下地区就可
log-machine-group: "my-k8s-group" #可以自定义机器组名称
log-config-path: "/etc/ilogtail/conf/cn-wulanchabu_internet/ilogtail_config.json" #修改cn-wulanchabu为实际project地域
log-ali-uid: "*********" #修改为阿里云UID在k8s集群详情中查看
access-key-id: "" #本教程用不上
access-key-secret: "" #本教程用不上
cpu-core-limit: "2"
mem-limit: "1024"
max-bytes-per-sec: "20971520"
send-requests-concurrency: "20"
2.计算alicloud-log-config.yaml的sha256 hash，并编辑ilogtail的DaemonSet YAML。
$ sha256sum alicloud-log-config.yaml
f370df37916797aa0b82d709ae6bfc5f46f709660e1fd28bb49c22da91da1214 alicloud-log-config.yaml
$ vim logtail-daemonset.yaml
在Vim中粘贴如下内容并保存（注意，修改注释中提示的字段，21、25行）。
apiVersion: apps/v1
kind: DaemonSet
metadata:
name: logtail-ds
namespace: kube-system
labels:
k8s-app: logtail-ds

3.应用YAML配置，创建ConfigMap和DaemonSet。
$ kubectl apply -f alicloud-log-config.yaml
configmap/alibaba-log-configuration created
$ kubectl apply -f logtail-daemonset.yaml
daemonset.apps/logtail-ds created
4.等待1分钟，检查DeamonSet是否正常运行
$ kubectl get -f logtail-daemonset.yaml
这个时候控制台应该打印出类似以下的消息，代表安装成功
NAME DESIRED CURRENT READY UP-TO-DATE AVAILABLE NODE SELECTOR AGE
logtail-ds 3 3 3 3 3
