prometheus is not scrapping the metrics from the app deployed on kubernetes -


i have added endpoint /metrics in app , config file have written prometheus

kind: configmap metadata:   name: prometheus-config apiversion: v1 data:   prometheus.yml: |-     global:       scrape_interval: 5s       evaluation_interval: 5s     scrape_configs:     - job_name: 'goserver'       scheme: http       tls_config:         ca_file: /var/run/secrets/kubernetes.io/serviceaccount/ca.crt       bearer_token_file: /var/run/secrets/kubernetes.io/serviceaccount/token       kubernetes_sd_configs:       - api_server: https://kubernets.default.svc         role: pod       relabel_configs:       - source_labels: [__meta_kubernetes_pod_label_app]         regex: goserver         action: keep       - source_labels: [__meta_kubernetes_pod_name]         target_label: k8s_pod         action: replace

and below deployment file 

apiversion: extensions/v1beta1 kind: deployment metadata:   name: prometheus-deployment spec:   replicas: 1   template:   metadata:     labels:       app: prometheus-server   spec:     containers:     - name: prometheus       image: prom/prometheus:latest       args:         - "-config.file=/etc/prometheus/conf/prometheus.yml"         # metrics stored in emptydir volume         # exists long pod running on node.         # data in emptydir volume safe across container crashes.         - "-storage.local.path=/prometheus"       ports:         - containerport: 9090       volumemounts:         - name: prometheus-server-volume           mountpath: /etc/prometheus/conf         - name: prometheus-storage-volume           mountpath: /prometheus   volumes:     - name: prometheus-server-volume       configmap:         name: prometheus-config     - name: prometheus-storage-volume       emptydir: {} # containers in pod can read , write same files here.

and deployment file app

apiversion: apps/v1beta1 kind: deployment metadata:   name: server-deployment   namespace: default spec:   replicas: 1   template:     metadata:       labels:          app: goserver     spec:       containers:       - name: goserver         imagepullpolicy:         image: utkarshmani1997/goserver:v1.4         ports:         - containerport: 8080

i have created service of prometheus , goserver on port 32514 , 32520 respectively of type nodeport. working fine minikube , scraps metrics app not working kubeadm setup in virtual box (multinode cluster). changes have make in order metrics on kubernetes. tried make few changes in rbac-setup.yaml , prometheus-kubernetes.yaml not working.

i accessing browser ssh -nl 1234:localhost:32514 outside cluster,because vagrant box not have ubuntu desktop ui.

i found issue,actually issue related rbac. didn't added serviceaccountname in deployment file. working fine new change.

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
