K8sGPT

介绍

k8sgpt 是一个扫描 Kubernetes 集群、诊断和分类问题的工具。它将 SRE 经验编入其分析器中，并帮助提取最相关的信息，通过人工智能来丰富它。它还可以与 OpenAI、Azure、Cohere、Amazon Bedrock 和本地模型结合使用。

部署 LocalAI

部署 LocalAI

配置 LocalAI

k8sgpt auth add --backend localai --model ggml-gpt4all-j --baseurl http://localhost:8080/v1k8sgpt auth list

测试诊断

部署创建带错误的 deployment

apiVersion: apps/v1kind: Deploymentmetadata:name: nginx-deploymentlabels:app: nginxspec:replicas: 3selector:matchLabels:app: nginxtemplate:metadata:labels:app: nginxspec:containers:- name: nginximage: nginx:1.14.2ports:- containerPort: 80securityContext:readOnlyRootFilesystem: true
# 部署kubectl apply -f ./nignx.yaml -n demo# 诊断k8sgpt analyze -n demo --explain --backend localai

大概意思是告诉你思路去排查吧，好像还很初级就是了，可以针对自己环境的问题做成文档喂给 AI，锻炼一下，就更有针对性。
