flask返回json数据

jsonify: 对数组直接可以使用 Content-Type: application/json

json.dumps() 返回类型:Content-Type: text/html; charset=utf-8

#方法1

return jsonify(list_dict)

#方法2

return json.dumps(list_dict)

#方法3

return Response(json.dumps(list_dict),content_type='application/json')

#方法4 同时返回状态 #return make_response(jsonify(list_dict),201)

restful访问istio的api 在kubernetes的apigroup中有以下个与istio有关，分别是

authentication.istio.io, config.istio.io, networking.istio.io

其中config.istio.io为最主要的，istio流量控制相关的

routerule, egressrule, destinationpolicie

策略执行相关的

memquota，quota，rule，QuotaSpec，QuotaSpecBinding

监控与日志配置相关的

metric, logentrie

http调用相关的

httpapispecbinding, tracespan, httpapispec

ctrl+space 提示快捷键

apiVersion: networking.istio.io/v1alpha3 http://192.168.11.51:1900/apis/networking.istio.io/v1alpha3/gateways

2、把其他例子一并搞完(deployment,patch,watch)

3、模仿sparrow例子(写个蓝绿，灰度，(AB的例子))

4、正式写案例

// 配置服务健康检查使用的 type HealthData struct { // 检查类型 HealthType string // 检查端口 HealthPort string // http访问路径 HealthPath string // 服务启动预计时间 HealthInitialDelay string // 检查间隔 HealthInterval string // 失败阈值 HealthFailureThreshold string // 检查超时 HealthTimeout string // 通过命令检查 HealthCmd string }

1、先创建名称空间

问题表单创建标签和 service的标签对不上导致一直503

序列化后的表单数据:{"project":"","environment":"dev","cluster":"k8s-cluster1","imageRepo":"myhub.mydocker.com","imageName":"",\

"imageTag":"","imagePullPolicy":"IfNotPresent","containerPort":"","replicas":"","cpu":"0.25","memory":"0.25","label_key1":"","label_value1":"",\

"label_key2":"","label_value2":"","probeType":"http","httpPort":"","healthPath":"","tcpPort":"8080","healthCmd":"ls /tmp","initialDelaySeconds":"30",\

"periodSeconds":"20","failureThreshold":"3","healthTimeout":"10","env":"","volumeMount":"","updateType":""}

1、创建集群 (集群名称,集群的配置文件config,云类型:私有云/公有云) 2、创建环境
3、创建harbor,仓库 4、创建项目，创建命名空间，选择注入（可以删除） 5、创建应用集群环境所属项目端口容器镜像 6、应用灰度,回滚,

跟命名空间无关: api版本 node namespaces storageclass pv

1、速率限制 2、负载均衡算法 3、熔断 https://istio.io/latest/docs/reference/config/networking/destination-rule/ # 熔断 trafficPolicy: connectionPool: tcp: maxConnections: 1 http: http1MaxPendingRequests: 1 maxRequestsPerConnection: 1 outlierDetection: # 开始拒绝连接的错误个数 consecutiveErrors: 1 interval: 1s baseEjectionTime: 3m maxEjectionPercent: 100 4、内外网 5、跨域（1 失败） 6、鉴权 7、请求超时 timeout: 7s 8、路由(vs,dr,redirect) 9、流量镜像 10、链路跟踪

1、添加agent 定义node label 2、checkout的证书ID 换成m-s里面定义的 credentialsId: 'gitee_account',
