在 k8s(kubernetes)中使用 Loki 进行日志监控_.net


安装helm环境


[root@hello ~/yaml]#
[root@hello ~/yaml]# curl https://baltocdn.com/helm/signing.asc | sudo apt-key add -
[root@hello ~/yaml]# sudo apt-get install apt-transport-https --yes
[root@hello ~/yaml]# echo "deb https://baltocdn.com/helm/stable/debian/ all main" | sudo tee /etc/apt/sources.list.d/helm-stable-debian.list
deb https://baltocdn.com/helm/stable/debian/ all main
[root@hello ~/yaml]# sudo apt-get update
[root@hello ~/yaml]# sudo apt-get install helm
[root@hello ~/yaml]#


添加安装下载源


[root@hello ~/yaml]# helm repo add loki https://grafana.github.io/loki/charts && helm repo update

查看安装后是否完成


[root@hello ~/yaml]# helm list -A

查看svc并修改类型


[root@hello ~/yaml]# kubectl  get svc

loki-headless ClusterIP None <none> 3100/TCP 2m58s
[root@hello ~/yaml]#


将svc设置为 type: NodePort


[root@hello ~/yaml]# kubectl  edit  svc loki
service/loki edited
[root@hello ~/yaml]#
[root@hello ~/yaml]# kubectl get svc
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE

[root@hello ~/yaml]#


查看nginx的pod


[root@hello ~/yaml]# kubectl apply -f nginx-app.yaml 
deployment.apps/nginx created
service/nginx created


[root@hello ~/yaml]# kubectl get pod | grep nginx
