Cloud Computing Project

Configuration

You should create a folder in a directory and put config files there (under the appConfigs directory in this repo).

Project Build & Run

Run ./mvnw clean package in the project folder; after a while, Maven prints out the project's jar file path on the terminal.

After maven build, the Jar file usually is in target/finalProject-0.1-spring-boot.jar, and you can run the application by the following command:

java -jar target/finalProject-0.1-spring-boot.jar --spring.config.name=applicationConfig,secretConfig --spring.config.location=file:///home/ali/appConfigs/

Note that applicationConfig.properties and secretConfig.properties are config files name under the directory of /home/ali/appConfigs/ that I had created before. Note that there is no need to change user value inside applicationConfig.properties if you are making database using below commands

Docker config

Method 1:

Docker Compose

First creat volume with docker volume create myDBVolume
Then build docker compose file with sudo docker-compose build
Finaly run the system with sudo docker-compose up
Note that domain address in ./appConfigs/applicationConfig.properties should be mysql

Method2:

Database build

Simply run

sudo docker run --detach --name={containerName} --env="MYSQL_ROOT_PASSWORD={rootPassword}" --publish {host port}:{DBport} --volume=/root/docker/{containerName}/conf.d:/etc/mysql/conf.d --volume={DBlocalStorage}:/var/lib/mysql mysql

application Dockerfile

Before doing the following steps, see ip address of database wiith sudo docker inspect {container name}and replace domain address in ./appConfigs/applicationConfig.properties with founded ip.
For creating docker runtime image of project run sudo docker build -t {your desired name of image} .
Then run the image using

sudo docker run --mount type=bind,src={HostPathToConfigFolder},target=/usr/src/conf -p {HostPort}:8081 -it {yourDesiredNameOfImage}

Minikube

Minikube installation

check out https://minikube.sigs.k8s.io/docs/start/
for x86-64 architucture follow these steps:

1. curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
2. sudo install minikube-linux-amd64 /usr/local/bin/minikube
3. minikube start
   Note that if part 3 didnt go well, try to contact me :)

Minikube project configs

try following steps in order and you will be fine! first go to the ./kuber path then:

data base deploy steps

1. minikube kubectl apply -f secret.yaml or sudo minikube kubectl -- apply -f secret.yaml

2. minikube kubectl apply -f config-map.yaml or sudo minikube kubectl -- apply -f config-map.yaml

3. minikube kubectl apply -f config-map2.yaml or sudo minikube kubectl -- apply -f config-map2.yaml

4. minikube kubectl apply -f mysql-storage.yaml or sudo minikube kubectl -- apply -f mysql-storage.yaml

5. minikube kubectl apply -f mysql-deployment.yaml or sudo minikube kubectl -- apply -f mysql-deployment.yaml
   after this step check the STATUS of pods by sudo minikube kubectl get pod -- -o wide command, it should be RUNNING after a while.

6. minikube kubectl apply -f mysql-service.yaml or sudo minikube kubectl -- apply -f mysql-service.yaml
   now database setup is completed. Use sudo minikube kubectl get deployment -- -o wide and sudo minikube kubectl get service -- -o wide for checking status.

urlshortener deploy steps

1. minikube kubectl apply -f secret.yaml or sudo minikube kubectl -- apply -f secret.yaml

2. minikube kubectl apply -f config-map.yaml or sudo minikube kubectl -- apply -f config-map.yaml

3. minikube kubectl apply -f config-map2.yaml or sudo minikube kubectl -- apply -f config-map2.yaml

4. minikube kubectl apply -f urlshortener-deployment.yaml or sudo minikube kubectl -- apply -f urlshortener-deployment.yaml
   after this step check the STATUS of pods by sudo minikube kubectl get pod -- -o wide command, it should be RUNNING after a while.

5. minikube kubectl apply -f urlshortener-service.yaml or sudo minikube kubectl -- apply -f urlshortener-service.yaml
   now database setup is completed. Use sudo minikube kubectl get deployment -- -o wide and sudo minikube kubectl get service -- -o wide for checking status.

If you reach here, It is all done. For testing your service try steps below:
Before moving forward save try to copy the ip of the service in the sudo minikube kubectl get service -- -o wide command.

Testing service pod

Method1:

1. sudo minikube kubectl run test -- --image=danialkm/myubuntu:latest sleep infinity
2. sudo minikube kubectl exec -- --stdin --tty test -- bash
   in the opened bash check the system working by typing Usage command below!
   Note that instead of localhost in the POST url, you need to type service ip.

Method2:
simply use sudo minikube kubectl port-forward service/urlshortener 8081:8081 and then you can use system with Usage command that is described below.

Usage

curl --location --request POST 'http://localhost:8081/doit' --header 'Content-Type: application/json' --data '{"url":"https://01d.ir/test"}'

you can go to the desired link by opening http://localhost:8081/{code}

Enjoy!
