Docker

Builds

Firstly, you build images.

docker build ./APIGATEWAY -t apigateway:marka
docker build ./AuthService -t authservice:marka
docker build ./UserService -t userservice:marka
docker build ./CodeService -t codeservice:marka
docker build ./TransactionService -t transactionservice:marka
docker build ./QRService -t qrservice:marka
docker build ./FrontEnd -t frontend:marka

Docker Compose

This is for quick check.

docker-compose up
docker-compose scale <service>=<replicas>
docker-compose down

Docker Stack (Swarm and Kubernetes)

By Docker Swarm

docker swarm init
docker stack deploy --orchestrator swarm --compose-file docker-compose.yml marka

By Kubernetes

docker stack deploy --orchestrator kubernetes --compose-file docker-compose.yml marka

To change service scale

docker service scale marka_frontend=2

List the stack

docker stack ls --orchestrator kubernetes

Remove the stack

docker stack rm marka --orchestrator kubernetes

###Kubernetes

Kompose

Install kompose to convert docker compose config for kubernetes. https://kubernetes.io/docs/tasks/configure-pod-container/translate-compose-kubernetes/#install-kompose

JMeter

jmeter -n -t test.jmx -l result.txt -j test.log 

MANUAL RUN

Requirements:

• NodeJS: https://nodejs.org/en/download/
• Docker (for mongodb) https://docs.docker.com/docker-for-windows/install/
• Yarn: https://classic.yarnpkg.com/en/docs/install#windows-stable

First, run mongo db

docker run -d -p 27017-27019:27017-27019 --name mongodb mongo

After, you should run services

cd ./AuthService 
yarn install
yarn start

cd ./UserService
yarn install
yarn start

cd ./CodeService
yarn install
yarn start

cd ./TransactionService
yarn install
yarn start

cd ./QRService
yarn install
yarn start

cd ./FrontEnd
yarn install
yarn start

Finally

cd ./APIGATEWAY
yarn install
yarn start

TODO

• Check and fix APIDOCS
• Create the APIDOCS on swagger
• Set frontend services for selectable API DOMAIN like as api1.marka.club and api2.marka.club
• Serve the frontend on https://marka.club as PWA
• Set Dockerfiles
• Create micro services and serve them

EXTRA

Mongo

• docker run -d -p 27017-27019:27017-27019 --name mongodb mongo
• docker exec -it mongodb bash

Mongo Sharding

Prerequisites

Install docker on your machine.

Preparation

Topology for our super simple cluster base on using:

• 1 node as config server
• 1 node as router (mongos)
• 2 nodes as shards

Create docker net for our cluster: docker network create --driver bridge xnet Run config node:

docker run -it --rm --net=xnet -p 27016:27016 \
    --hostname config-1 --name config-1 \
    mongo:3.4.9 --port 27016 --replSet config --configsvr

Init config node (init Replica Set for config):

docker exec -it config-1 mongo --port 27016 --eval '
    rs.initiate({ _id: "config", members: [
        { _id : 0, host : "config-1:27016" }
    ]});
'

Run router node (mongos):

docker run -it --rm --net=xnet -p 27015:27015 \
    --hostname mongos --name mongos \
    mongo:3.4.9 mongos \
    --port 27015 --configdb config/config-1:27016

Run node for shard 1:

docker run -it --rm --net=xnet -p 27018:27018 \
    --hostname shard-1 --name shard-1 \
    mongo:3.4.9 --port 27018 --shardsvr

Run node for shard 2:

docker run -it --rm --net=xnet -p 27019:27019 \
    --hostname shard-2 --name shard-2 \
    mongo:3.4.9 --port 27019 --shardsvr

All nodes already launched, it’s time to configure sharding cluster:

docker exec -it mongos mongo --port 27015 --eval '
    sh.addShard("shard-1:27018");
    sh.addShard("shard-2:27019");
    sh.enableSharding("test_db");
    sh.shardCollection("test_db.test_collection", {"tag": 1});
    sh.status();
