k8s Monitoring via Image Processing Example

Image Processing K8s Monitoring

Preparation and Scoping

  • a server for hosting e.g. test-host
    • Monitoring Server Apps:
      • Prometheus
      • Grafana
    • Logging Server Apps:
      • Elasticsearch
      • Kibana
    • Tracing Server Apps:
      • Jaeger
  • 4 node K8s Cluster: Master x 1 and Slaves x 3 e.g. img-test-01~04
    • Monitoring Client Apps
      • Node Exporter
      • Kube-state-metrics
      • cAdvisor
    • Logging
      • Fluentd
  • Opentracing Module: It's Python Module, thus it can be your local and in the future, it can be your container image wrap your features/applications.

Default K8s Dashboard:

Original K8s Dashboard - https://kubernetes.io/docs/tasks/access-application-cluster/web-ui-dashboard/

Steps on K8s Controller

install Default K8s Dashboard
```
$ kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.0/aio/deploy/recommended.yaml
```
Leverage Kubctl Proxy to forward port 8001
```
### $ kubectl proxy&
[idps@img-test-01 ~]$ kubectl proxy&
[1] 12911
[idps@img-test-01 ~]$ Starting to serve on 127.0.0.1:8001
```
Get Token
```
### $ Create Account and Get Token
[idps@img-test-01 ~]$ kubectl create serviceaccount dashboard-admin-sa
serviceaccount/dashboard-admin-sa created

[idps@img-test-01 ~]$ kubectl create clusterrolebinding dashboard-admin-sa --clusterrole=cluster-admin --serviceaccount=default:dashboard-admin-sa
clusterrolebinding.rbac.authorization.k8s.io/dashboard-admin-sa created

[idps@img-test-01 ~]$ kubectl get secrets
NAME                             TYPE                                  DATA   AGE
dashboard-admin-sa-token-rkq7z   kubernetes.io/service-account-token   3      41s
default-token-9kt7g              kubernetes.io/service-account-token   3      114d

[idps@img-test-01 ~]$ kubectl describe secret dashboard-admin-sa-token-rkq7z
Name:         dashboard-admin-sa-token-rkq7z
Namespace:    default
Labels:       <none>
Annotations:  kubernetes.io/service-account.name: dashboard-admin-sa
            kubernetes.io/service-account.uid: 94726478-8d7c-4dac-8c4c-7d8edadc5e20

Type:  kubernetes.io/service-account-token

Data
====
ca.crt:     1025 bytes
namespace:  7 bytes
token:      xxx
```
Steps on Local to access K8s Default Dashboard
```
### create ssh tunnel , you can use $ps -ef | grep ssh and if there is no ssh tunnel processing running please re-run it.
~ ssh -g -L 8001:localhost:8001 -f -N idps@172.30.30.106
idps@172.30.30.106's password:
~
```
put the url and login via token you found from the new account

Prometheus w/ Node Exporter

Node Exporter: https://github.com/prometheus/node_exporter

  • install node exporter can reference nttd_playbook repo

    Kube-state-metrics

  • Kube-state-metrics listens to the Kubernetes API server and generates metrics about the state of numerous Kubernetes objects, including cron jobs, config maps, pods, and nodes. These metrics are unmodified, unlike kubectl metrics that use the same Kubernetes API but apply some heuristics to display comprehensible and readable messages.
Install from github
```
git clone https://github.com/kubernetes/kube-state-metrics.git
cd kube-state-metrics
kubectl apply -f examples/standard
```
Install from helm chart
```
helm repo add kube-state-metrics https://kubernetes.github.io/kube-state-metrics
helm repo update

Write OpenTracing Python Example

create python virtual env

  • Local Env Preparation 

     $ mkdir opentracing
 $ cd opentracing
 $ virtualenv venv
 $ cd venv
 $ venv source ./bin/activate
 $ (venv)  venv pip install jaeger-client
 $ pip install ipython
prepare a config.py and copy it for configuring the Tracer and trace sample code

  • local_agent, 'reporting_host': '<your jaeger server name>' and 'reporting_port': '<your jaeger port , default udp 5775>'

     $ mkdir demo

Step 2: run init_tracer module for initializing Jaeger Tracer with UDP reporter
```
In [2]: tracer = init_tracer('first-service')
Initializing Jaeger Tracer with UDP reporter
Using selector: KqueueSelector
Using sampler ConstSampler(True)
opentracing.tracer initialized to <jaeger_client.tracer.Tracer object at 0x10cb455b0>[app_name=first-service]
```
Step 3: create 1st span
```   
In [3]: with tracer.start_span('first-span') as span:
...:     span.set_tag('first-tag', '100')
...:
Reporting span bc1f64a0ee94e229:fa3903683ae96d36:0:1 first-service.first-span
```
Step 4: start a span within another span, create 2nd span and also 3rd span
```   
In [4]: with tracer.start_span('second-span') as span2:
...:     span2.set_tag('second-tag', '90')
...:     with tracer.start_span('third-span') as span3:
...:         span3.set_tag('third-tag', '80')

Reporting span a87effad357e5e1b:fc511d3bbfdd5c4a:0:1 first-service.second-span
```
Step 5: create 4th span and child 5th span
```
In [5]: with tracer.start_span('fourth-span') as span4:
...:     span4.set_tag('fourth-tag', '60')
...:     with tracer.start_span('fifth-span', child_of=span4) as span5:

Tracing an HTTP Requests Example

Step 6: for a run the next example we need to install the python-requests module
```
In [6]: !pip install requests

```
Step 7: import requests module
```
In [7]: import requests
```
Step 8: create a homepages list
```
In [8]: homepages = []
```
Step 9: use requests to query the Github jobs API for Python jobs, and then get each Company’s listed website.
```
In [9]: res = requests.get('https://jobs.github.com/positions.json?description=python')
Starting new HTTPS connection (1): jobs.github.com:443
https://jobs.github.com:443 "GET /positions.json?description=python HTTP/1.1" 200 None
```
Step 10: without trace span, just for loop and try to connect company website
```
In [10]: for result in res.json():
    ...:     print('Getting website for %s' % result['company'])
    ...:     try:
    ...:         homepages.append(requests.get(result['company_url']))
    ...:     except:
    ...:         print('Unable to get site for %s' % result['company'])
