cpu-core-limit: "2"

mem-limit: "1024"

max-bytes-per-sec: "20971520"

2.计算alicloud-log-config.yaml的sha256 hash，并造出版人ilogtail的DaemonSet YAML。

$ sha256sum alicloud-log-config.yaml

f370df37916797aa0b82d709ae6bfc5f46f709660e1fd28bb49c22da91da1214 alicloud-log-config.yaml

$ vim logtail-daemonset.yaml

在Vim之前粘贴如下素材并保留（注意到，重写注解之前指引的URL，21、25在行）。

3.应用领域YAML装配，创设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是否短时间运在行

$ kubectl get -f logtail-daemonset.yaml

这个时候基本功能应该打印造出相同不限的消息，值得一提的是装有获得成功

NAME DESIRED CURRENT READY UP-TO-DATE AVAILABLE NODE SELECTOR AGE

logtail-ds 3 3 3 3 3 2m1s

上报历史记录并查看 创设一个常用持续转化历史记录的Pod。

$ vim demo-pod.yaml

在Vim之前粘贴如下素材并保留（注意到，确实需要重写注解之前指引的URL，8-9在行）。

apiVersion: v1

kind: Pod

metadata:

labels:

name: demo-pod

name: demo-pod

spec:

# imagePullSecrets: # Comment out to enable specific image pull secret

# - name: myregistrykey # repleace it to specific registry key containers

containers:

- image: busybox

imagePullPolicy: IfNotPresent

name: demo-pod

command: ["/bin/sh"]

args: ["-c", "while true; do echo $(date)>>/tmp/demo.log; sleep 10; done"]

resources: {}

securityContext:

capabilities: {}

privileged: false

terminationMessagePath: /dev/termination-log

dnsPolicy: ClusterFirst

restartPolicy: Always

应用领域YAML装配，创设Pod

$ kubectl apply -f demo-pod.yaml

pod/demo-pod created

2.送回Web基本功能，首页装配完毕应用领域程序的“检索历史记录”跳转到历史记录检索应用领域程序。首页首页右下侧的“放大镜”屏幕，选之前logstore，首页“眼睛”屏幕，在右下侧造出现的“消费截图”侧边栏之前尝试调整Shard和时间以内，首页截图查看上报的历史记录。
