【故障排查】【杂项】ingress + Jenkins 上传hpi文件（8MB）报错413

1、ingress + Jenkins 上传hpi文件（8MB）报错 413 Request Entity Too Large

处理方法：ingress文件加上annotations
ingress-nginx 实际上为nginx，所以在此调整。

apiVersion: extensions/v1beta1
kind: Ingress
metadata:name: jenkins-ingressnamespace: opsannotations:nginx.ingress.kubernetes.io/proxy-body-size: "100m" # 设置最大请求体大小为100MB
spec:ingressClassName: "nginx"

题外话：部署ingress-nginx

#在需要部署ingress-nginx的节点上打上node label标签。 (因为下方daemonSet做了 nodeSelector限制)
nodeSelector:                             # 节点选择器kubernetes.io/os: linuxnode-role: ingress########
kubectl label nodes <node-name> node-role=ingress

2、部署ingress，节点node2报错。 关机调大CPU核数。

情况描述：node1和node2都打上了标签node-role=ingress 。 但部署在node2的ingress出现pending状态。

又说api调度出问题的。CPU不足的。<font color=red>后面关机node2，将CPU调大。然后就正常调度了 </font>
（一个初始化的环境，df -mh ，free -mh ， top都是正常的）

3、虚拟机寄了，使用xfs_repair -L修复

XFS (dm-0) failed to recover intens
failed to mount /sysroot

处理方法

#救援模式
xfs_repair -L /dev/mapper/centos-root

4、kibana无法显示很长的java报错日志

处理方法：

点击+号没用，要去设置kibana的单元高度

设置单元高度后，能完整显示了：

5、解惑镜像logstash-oss:7.17.6为何能写相对路径args: [“-f”,“config/logstash.conf”]

答：因为这个镜像构建的时候 WORKDIR是WORKDIR /usr/share/logstash
#把它层级剖出来
docker history --no-trunc -H  xxxxx/base/logstash-oss:7.17.6 > /tmp/1.txt

下面是docker history的内容

6、pipeline构建报错

报错信息：

[Pipeline] Start of Pipeline
[Pipeline] podTemplate
[Pipeline] // podTemplate

7、pipeline构建报错 （script.sh: 4: Syntax error: “(” unexpected）

报错信息：

/home/jenkins/agent/workspace/springcloud-ruoyi-CI@tmp/durable-92841ede/script.sh: 4: Syntax error: "(" unexpectedscript returned exit code 2

处理方式：

需要写成 （原理未知？！）
sh '''#!/bin/bash
