在开发运维过程中,错误码系统是快速定位问题的第一道防线。Super Dock作为企业级容器管理平台,其错误码设计遵循"分类明确、信息完整、便于排查"的原则。整套体系采用HTTP状态码+业务码的复合编码方式,通过6位数字实现精准错误定位。
标准错误码格式为:XXYYZZ
XX:主分类码(10-99)YY:子模块码(00-99)ZZ:具体错误序号(00-99)例如错误码401203表示:
40:资源操作类错误12:存储卷模块03:具体为存储配额不足错误bash复制kubectl describe quota -n <namespace>
bash复制kubectl get pv | grep Released | awk '{print $1}' | xargs kubectl delete pv
yaml复制apiVersion: storage.k8s.io/v1
kind: StorageClass
parameters:
size: "500Gi"
关键点:存储配额计算包含PVC和临时存储,扩容后需等待5分钟生效
bash复制kubectl describe pod <pod-name> | grep -A 10 Events
bash复制kubectl get nodes --show-labels | grep <label-key>
yaml复制resources:
requests:
cpu: "1"
memory: "2Gi"
limits:
cpu: "2"
memory: "4Gi"
推荐采用错误码生成器:
go复制func NewErrorCode(module int, sequence int) int {
base := 40 * 10000 // 模块基础码
return base + module*100 + sequence
}
// 使用示例
const (
ErrVolumeMountFailed = NewErrorCode(12, 15) // 401215
)
错误模板配置示例:
json复制{
"401203": {
"en": "Storage quota exhausted",
"zh": "存储配额不足",
"solution": {
"doc": "https://docs.superdock.io/storage/quota",
"steps": ["check_quota", "clean_pv"]
}
}
}
示例关键指标监控:
yaml复制groups:
- name: superdock-errors
rules:
- alert: HighErrorRate
expr: rate(superdock_errors_total{code=~"5.."}[5m]) > 10
labels:
severity: critical
annotations:
summary: "High error rate ({{ $value }})"
log复制{"error_code":401203,"trace_id":"abc123","timestamp":"2023-07-20T08:00:00Z"}
json复制{
"query": {
"term": {
"error_code": 401203
}
}
}
现象:容器间通信间歇性失败
排查工具:
bash复制# 容器网络诊断
kubectl run -it --rm debug --image=nicolaka/netshoot --restart=Never -- bash
# 在诊断容器中执行
mtr -rw <目标IP>
解决方案:
典型处理流程:
bash复制kubectl get secret <secret-name> -o yaml | grep "\.dockerconfigjson"
bash复制docker pull <image>:<tag> --creds=<user>:<pass>
yaml复制imagePullSecrets:
- name: regcred
imagePullPolicy: IfNotPresent
结合Swagger生成错误码文档:
yaml复制responses:
400:
description: |
Error Code:
- 401203: Storage quota exhausted
- 501107: Pod scheduling failed
schema:
$ref: '#/definitions/ErrorResponse'
实现错误码分类处理器:
javascript复制class ErrorHandler {
static handle(code) {
switch(Math.floor(code/10000)) {
case 40: return this._handleStorageError(code);
case 50: return this._handleSchedulingError(code);
// ...
}
}
static _handleStorageError(code) {
const subCode = Math.floor((code%10000)/100)
switch(subCode) {
case 12: return alert('存储卷操作失败');
// ...
}
}
}
