e2e-hello CASE Documentation\n\nThis Project contains couple of major point shown below.\n\n* Application\n    * Codebase\n    * Helm Chart\n\n* Kubernetes Cluster (gcloud)\n* Monitoring\n    * Prometheus/Grafana\n    * PrometheusAdapter/CustomMetrics\n    * PrometheusExporter of application\n\n* CI/CD Pipeline\n    * * Jenkins\n    * * Docker/Helm\n\n# Application\n\n## CodeBase\nThis is a simple python application you can see the codebase and Dockerfile under `application` directory.\nYou can build shown on docker environment.\n\n```\n    $ docker build .\n\n```\n\nLocal:\n```\n    $ pip3 install -r requirements.txt\n    $ python3 app.py\n```\n\nApplication contains prometheus exporter and it returning `/metrics` endpoint successfully to gather metrics.`/hi` endpoint returins valid JSON response.\n\n\n## HelmChart\nHelmChart located on `application/hello-world` directory.You can update values under values.yaml file.\n\n# KUBERNETES CLUSTER\nI have setup a cluster on google-cloud for development purposes.\nThe command is shown as below:\n```\n    $ gcloud container clusters create MY_CLUSTER \\\n        --zone compute-zone\n\n```\n\nNotice: Metric-server already installed on GKE based clusters.If they don't I prefer to use this manifest file shown below:\nNginxIngress able to us accept traffic easily:\n\n```\n    $ helm install --name nginx-ingress stable/nginx-ingress\n```\n\n# Monitoring\nYou can see general architectural diagram with explanation shown below.\nI have used prometheusoperator with helm chart, it has couple of ability to access Dasboard and a lots of CRD options to easily automate and manage prometheus via simple manifest files.\n\n\u003cimg src=\"./img/monitoring.png\"\u003e\u003c/img\u003e\n\n\nIn this project you can see the installation scripts under `./create_cluster/components.sh` directory.\nBy the I have added an example to get alert activity via webhook please check the directory autoscaler directory.It is a simple application that listen incoming payload from Alert Manager, to send the alerts via webhook you see the definition under cluster `operator.yaml` file.\n\n`cluster-autoscaler-rules` containing application level alert defintion for prometheus and alertmanager, when you set up operator those definiton will appear on prometheus monitor.\n\n# CI/CD Pipeline\n\nI have used jenkins to build and deploy application.I set up `jenkins ` via helm chart, under the `jenkins` directory, it is has a installation script `setup_jenkins.sh`\n\nJobs are configured to poll changes from github.Jenkins configured to use `kubernetes` for run the `runner` agent to execute the jobs.\n\nYou can see the diagram below.\n\u003cimg
