devops-microservices

DevOps in distributed system

• Deploy OpenShift with Minishift
  • Deploy a sample Multi-services application on OpenShift
  • Builds, Build Triggers, Image streams, Deployments

Project description

• Implementation of different methods towards DevOps - within microservice architecture

• Parse-server :

  • image built in docker container - kubernetes as orchestration tool
  • deploy the parse- server to kubernetes cluser (of course with already configured kubernetes)
  • Redis service
    • Create a kubernetes service

OpenShift

• oc login

• Build & deployment

  • image stream
  • OS registry, Docker hub
  • build config
  • docker strategy/ source strategy
  • build trigger
  • automate build
  • roling update
  • Blue/green strategy
  • A/B strategy deployment 80 % 20 %
  • oc rollout latest ..

• network

  • SDN

    • plugin
    • overlay network

  • openvswitch

  • DNS server

• service & route

• LB

  • define security
  • split traffic

• scaling : replicas

• storage

  • persistent volumne

• template & catalog

  • oc create -f template-config.yml

Example architecture deployment

• service (source strategy deployment)

  • deploy redis service
    • redis template
  • add python app deployment
    • add env for password of redis
  • PostgreSQL service
  • add node.js app deployment

• docker strategy deloyment worker

AWS

Google cloud platform

• gcloud init

• CD/CI

  • CI
    • Code commit on Github
    • CI server pools repo, run test
    • CI server sends notification - feedback of the integration test (script = CI server )
  • CD
    • Branches
    • Unit test
    • Automatic test
    • Code promotion

• Docker - Kubernetes

  • Google compute engine
  • Create Kubernetes cluster
    • Cluster is ready -> get credentials
    • Deploy
    • Config load balancer
    • K8 UI
      • IAM

• Jenkins

  • Google Kubernetes engine
  • Jenkins in the cluster
  • Google Cloud Container Registry and Google Cloud Storage
  • Get credentials : gcloud container clusters get-credentials --zone us-east1-b jenkins-cd
  • Jenkins architecture : Master - Slave -> scale the job
    • 2 nodes
    • Config Jenkins :
    • Create jenkins service
      • Jenkins UI
      • Jenkins discovery

• Google App Engine

  • Google source repository
  • Start up / reboot script
  • Create and config GCE instance
  • Host on GAE
  • Host on Kubernetes Engine
  • Host on Google Cloud function
  • Deploy the application
    • Create and configure GCE instance
  • App Engine resource and integration
    • Data storage, Memcache, Cloud storage, Mail, Scheduled task, Task queue.
    • Push - Pull queues

• Database : +
