TodoApp For Microservices

This project is a todo application that uses a microservice architecture.

It was created for learning microservice architecture.

The base minimum configuration is v1.x.x Version Line.

Additional microservices and external WebAPI examples are in v2.x.x Version Line.

Easy to understand how to add samples and services.
Can be used as a sample or template.

Deployment

Docker

Requirements

Docker
Docker Compose (If you have less than Compose V2, use the docker-compose command instead of the docker compose command.)

git clone https://github.com/Yutaro-B18016/TodoApp-For-Microservices.git

cd TodoApp-For-Microservices/deploy/compose

docker compose up -d --build

After deployment, it can be accessed on localhost:5000.

You can use Adminer on localhost:8080 to access the DB.(The default is tododb for Server, todoapi for user, toadoapi for password, and todoapi for database.)

Kubernetes

Requirements

kubectl (Able to manipulate target Kubernetes)
Docker
skaffold

git clone https://github.com/Yutaro-B18016/TodoApp-For-Microservices.git

cd TodoApp-For-Microservices/

SKAFFOLD_DEFAULT_REPO=$DOCKER_REGISTRY skaffold -n $DEPLOY_NAMESPACE run

$DOCKER_REGISTRY needs to be changed to your Docker Registry, and $DEPLOY_NAMESPACE to your deploy namespace.

If you use the default namespace, -n $DEPLOY_NAMESPACE is optional.

If you are using a local Docker Registry such as Minikube, SKAFFOLD_DEFAULT_REPO=$DOCKER_REGISTRY is not necessary.

After deployment, it can be accessed on Node IP:31000 using the node port.

The data in the DB is not persistent.

Sample NS/SC/PV/PVC (Use the sample to make the data persistent.)

The sample PV uses Node local.(It is not possible to increase the value of replicas in the database.)

The node-name in Todo-SC.yml needs to be changed to your node name.

git clone https://github.com/Yutaro-B18016/TodoApp-For-Microservices.git

cd TodoApp-For-Microservices/deploy/k8s/

kubectl apply -f Todo-NS.yml

sudo mkdir -p /mnt/kubernetes/tododb

sudo chmod 777 /mnt/kubernetes/tododb

sudo mkdir -p /mnt/kubernetes/boarddb

sudo chmod 777 /mnt/kubernetes/boarddb

sudo mkdir -p /mnt/kubernetes/boarddb-data

kubectl apply -f Todo-SC.yml

cd ../../

SKAFFOLD_DEFAULT_REPO=$DOCKER_REGISTRY skaffold -n todoapp run

cd ./deploy/k8s/

kubectl apply -n todoapp -f TodoDB-PVC.yml

kubectl apply -n todoapp -f BoardDB-PVC.yml

Access using Ingress

The default Ingress Controller is required.

After deploying the app, do the following.

git clone https://github.com/Yutaro-B18016/TodoApp-For-Microservices.git

cd TodoApp-For-Microservices/deploy/k8s/

kubectl apply -n $DEPLOY_NAMESPACE -f Tododb-Ingress.yml

After deployment, it can be accessed by Ingress.

Accessing the DB using Adminer

git clone https://github.com/Yutaro-B18016/TodoApp-For-Microservices.git

cd TodoApp-For-Microservices/deploy/k8s/

kubectl apply -n $DEPLOY_NAMESPACE -f Tododb-Console.yml

After deployment, it can be accessed on Node IP:31880 using the node port.(The default is tododb or boarddb for Server, todoapi or boardapi for user, toadoapi or boardapi for password, and todoapi or boardapi for database.)

Development

Requirements

Docker
Docker Compose
Visual Studio Code
Remote - Containers (VSCode Extentions)
Docker (VSCode Extentions)

TodoApi/TodoUI/BoardApi

Open the TodoApi/TodoUI/BoardApi directory in VSCode.

After opening, select Reopen in Container in the notification at the bottom right.

BoardApi: After opening the DEV Container in VSCode, run yarn install in a terminal.
