Running config maps and secrets

1. Running config maps to load env variable for our microservices

$ cd configMaps-secrets/configMaps
$ kubectl create -f configMaps.yml
$ kubectl get configmap

2. Running secrets to load env variable for our microservices to load username and pass safely instead of hardcoding

$ cd configMaps-secrets/secrets
$ kubectl create -f secrets.yml
$ kubectl get secrets

Run jenkins in kubernetes

1. Deploy

$ cd jenkins
$ kubectl create -f deployment.yml

2. get external svc port is it deployed to

$ kubectl get scv

2. access jenkins http://minikubeip:scvport

Deploying DB2

1. Navigate to db2-microservice folder

$ cd db2-microservice

2. Deploy to minikube

$ kubectl create -f service-deployment.yml

3. Get pods name of db2

$ kubectl get pods

4. ssh to pods container of db2

$ kubectl exec -it podname bash

5. switch user to db2inst1

$ su - db2inst1

6. Create Database and connect to it

$ db2 create database SAMPLE
$ db2 connect to SAMPLE

7. Download existing flight data from github and set permissions

$ wget https://raw.githubusercontent.com/SaifRehman/ICP-Airways/master/dataset/flights.csv
$ chown db2inst1:db2inst1 /home/db2inst1/flights.csv

8. Create Database and importing existing data to Flights table

• Flights Table

db2 CREATE TABLE "SAMPLE.FlightsData (ID int NOT NULL , Year varchar(255) NULL , Month varchar(255) NULL, DayofMonth varchar(255) NULL, DepTime varchar(255) NULL,  CRSDepTime varchar(255) NULL, ArrTime varchar(255) NULL, CRSArrTime varchar(255) NULL, FlightNum varchar(255) NULL, TailNum varchar(255) NULL, ActualElapsedTime varchar(255) NULL, CRSElapsedTime varchar(255) NULL, Airtime varchar(255) NULL, ArrDelay varchar(255) NULL, DepDelay varchar(255) NULL,   Origin varchar(255) NULL, Dest varchar(255) NULL, Distance varchar(255) NULL, PRIMARY KEY (ID))"

• User Table

db2 CREATE TABLE "SAMPLE.UserData (UserID int NOT NULL GENERATED ALWAYS AS IDENTITY (START WITH 1 INCREMENT BY 1) , LastName varchar(255) NULL , FirstName varchar(255) NULL, Location varchar(255) NULL, Email varchar(255) NULL,  Password varchar(255) NULL, Age int NULL, PRIMARY KEY (UserID))"

• Booking Table

db2 CREATE TABLE "SAMPLE.Booking (BookingID int NOT NULL GENERATED ALWAYS AS IDENTITY (START WITH 1 INCREMENT BY 1) ,TS TIMESTAMP NOT NULL , Checkin varchar(255) NOT NULL, UserID INT NOT NULL, FlightID INT NOT NULL, FOREIGN KEY (UserID) REFERENCES SAMPLE.UserData(UserID), FOREIGN KEY (FlightID) REFERENCES SAMPLE.FlightsData(ID), PRIMARY KEY (BookingID))"

• Importing existing data to flights table

$ db2  IMPORT FROM "/home/db2inst1/flights.csv" OF DEL INSERT INTO SAMPLE.FlightsData
