iLogtail使用入门-K8S环境快照采集到SLS

it: "1024"

max-bytes-per-sec: "20971520"

send-requests-concurrency: "20"

2.计算alicloud-log-config.yaml的sha256 hash，并校对ilogtail的DaemonSet YAML。

$ sha256sum alicloud-log-config.yaml

f370df37916797aa0b82d709ae6bfc5f46f709660e1fd28bb49c22da91da1214 alicloud-log-config.yaml

$ vim logtail-daemonset.yaml

在Vim中的嵌入如下以下内容并留有（注意，重写注释中的高亮的报文，21、25行）。

3.技术的发展YAML装配，始创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

这个时候的设备应该打印造出类似以下的谣言，代表内置事与愿违

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

logtail-ds 3 3 3 3 3 2m1s

上报快照并转发 始创一个用于持续生成快照的Pod。

$ vim demo-pod.yaml

在Vim中的嵌入如下以下内容并留有（注意，可能会并不需要重写注释中的高亮的报文，8-9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

技术的发展YAML装配，始创Pod

$ kubectl apply -f demo-pod.yaml

pod/demo-pod created

2.回到Web的设备，点选装配已完成技术的发展程序的“转发快照”跳转到快照转发技术的发展程序。点选首页左面的“方是”屏幕，选中的logstore，点选“嘴唇”屏幕，在左面造出现的“购物演示”侧边右上角的无论如何修正Shard和小时覆盖范围，点选演示转发上报的快照。
