The Saga 11 | pattern is implemented using the Outbox pattern for consistent communication. 12 | 13 | * **📦 Order Service:** 14 | - Receives and processes customer orders. 15 | - Creates order records in the database upon order reception. 16 | 17 | * **📦 Stock Service:** 18 | - Manages product stock. 19 | - Receives an order message to reserve products in stock. 20 | - Confirms reservation, updates the database, and records a message in the Outbox table. 21 | 22 | * **💳 Payment Service:** 23 | - Processes order payments. 24 | - Receives an order message for payment authorization. 25 | - Validates payment, authorizes it, updates the database, and records a message in the Outbox table. 26 | 27 | ### ⚙️ Execution Flow: 28 | 29 | 1. Customer places an order through the Order service. 30 | 2. Order service creates a record in the Outbox table with order details. 31 | 3. Message is sent to the Stock service to reserve products. 32 | 4. Stock service confirms reservation, updates its database, and records a message in the Outbox table. 33 | 5. Message is sent to the Payment service for payment authorization. 34 | 6. Payment service validates payment, authorizes it, updates its database, and records a message in the Outbox table. 35 | 7. Order service periodically checks the Outbox table to process pending messages. 36 | 8. If successful, the order is marked as confirmed, and the customer is notified. 37 | 38 | ![Flow](docs/flow.png) 39 | 40 | ### 🏗️ Infrastructure 41 | 42 | This repository provides configuration files for deploying three Django services (Order, Stock, Payment) on Kubernetes 43 | and Docker Compose. Each service has its PostgreSQL database, and RabbitMQ facilitates communication.

-------------------------------------------------------------------------------- /k8s/k3d/README.md: -------------------------------------------------------------------------------- 1 | # k3d - Lightweight Kubernetes Distribution 🌟 2 | 3 | k3d is a tool designed to easily create, manage, and operate Kubernetes clusters. It is lightweight, efficient, and provides a seamless way to work with Kubernetes clusters for development and testing purposes. 4 | 5 | ## Installation 🚀 6 | 7 | ### Linux: 8 | 9 | ```bash 10 | curl -s https://raw.githubusercontent.com/rancher/k3d/main/install.sh | bash 11 | ``` 12 | 13 | ### macOS: 14 | 15 | ```bash 16 | brew install k3d 17 | ``` 18 | 19 | ### Windows: 20 | 21 | You can download the latest executable from the [official GitHub releases page](https://github.com/rancher/k3d/releases) and add it to your PATH. 22 | 23 | ## Creating a Cluster 🛠️ 24 | 25 | You can create a cluster with or without specifying the number of server nodes. Below are two methods: 26 | 27 | ### Method 1: Creating a Cluster with Server Nodes 28 | 29 | To create a cluster with server nodes, you can use the following command: 30 | 31 | ```bash 32 | k3d cluster create saga --servers 3 --agents 3 --port '8080:30000@loadbalancer' 33 | ``` 34 | 35 | This command creates a Kubernetes cluster named "saga" with port forwarding configured to forward traffic from port 8080 on the host to port 30000 on the load balancer, along with three server nodes and three agent nodes, providing a comprehensive environment for your Kubernetes development and testing needs. 36 | 37 | ### Method 2: Creating a Cluster without Agent Nodes 38 | 39 | If you don't need agent nodes and only want server nodes, you can create a cluster without specifying the number of agent nodes. Here's how: 40 | 41 | ```bash 42 | k3d cluster create saga --port '8080:30000@loadbalancer' 43 | ``` 44 | 45 | This command creates a Kubernetes cluster named "saga" with port forwarding configured to forward traffic from port 8080 on the host to port 30000 on the load balancer, along with three server nodes. This setup is suitable for scenarios where you only require server nodes for your Kubernetes environment. 46 | 47 | ### Deleting a Cluster 🗑️ 48 | 49 | To delete a cluster, use this command: 50 | 51 | ```bash 52 | k3d cluster delete saga 53 | ``` -------------------------------------------------------------------------------- /k8s/kong/README.md: -------------------------------------------------------------------------------- 1 | # Kong Ingress Controller Installation Guide 🛠️ 2 | 3 | This guide will walk you through the steps to install Kong Ingress Controller on your Kubernetes cluster. 4 | 5 | ### Prerequisites ✔️ 6 | 7 | - [Access to a Kubernetes cluster](../k3d/README.md) 8 | - `kubectl` configured to communicate with your cluster 9 | - [Helm installed](https://helm.sh/docs/intro/install/) 10 | 11 | ### Installation Steps 🚀 12 | 13 | ## Install the Gateway APIs 14 | 15 | 1. **Install the Gateway API CRDs before installing Kong Ingress Controller.** 16 | 17 | ```bash 18 | kubectl apply -f https://github.com/kubernetes-sigs/gateway-api/releases/download/v1.0.0/standard-install.yaml 19 | ``` 20 | 21 | 2. **Create a Gateway and GatewayClass instance to use.** 22 | 23 | ```bash 24 | kubectl apply -f kong/kong-gateway.yaml 25 | ``` 26 | 27 | 3. **Helm Chart Installation** 28 | 29 | 1. Add the Kong Helm charts: 30 | ```bash 31 | helm repo add kong https://charts.konghq.com 32 | ``` 33 | 2. Update repo: 34 | ```bash 35 | helm repo update 36 | ``` 37 | 3. Install Kong Ingress Controller and Kong Gateway with Helm: 38 | ```bash 39 | helm install kong kong/ingress -n kong --create-namespace --values kong/values.yaml 40 | ``` 41 | 42 | 4. **Verify Installation** 43 | 44 | After installation, ensure that Kong Ingress Controller pods are running: 45 | 46 | ```bash 47 | curl -i 'localhost:8080' 48 | ``` 49 | 50 | The results should look like this: 51 | ```bash 52 | HTTP/1.1 404 Not Found 53 | Date: Sun, 28 Jan 2024 19:14:45 GMT 54 | Content-Type: application/json; charset=utf-8 55 | Connection: keep-alive 56 | Content-Length: 103 57 | X-Kong-Response-Latency: 0 58 | Server: kong/3.5.0 59 | X-Kong-Request-Id: fa55be13bee8575984a67514efbe224c 60 | 61 | { 62 | "message":"no Route matched with those values", 63 | "request_id":"fa55be13bee8575984a67514efbe224c" 64 | } 65 | ``` 66 | **Note:** 67 | 68 | If you encounter `curl: (52) Empty reply from server`, please wait a moment and try again. 69 | 70 | ### Uninstallation ❌ 71 | 72 | To uninstall Kong Ingress Controller, simply delete the Helm release: 73 | 74 | ```bash 75 | helm uninstall kong -n kong 76 | ``` -------------------------------------------------------------------------------- /k8s/kong/kong-gateway.yaml: -------------------------------------------------------------------------------- 1 | --- 2 | apiVersion: gateway.networking.k8s.io/v1 3 | kind: GatewayClass 4 | metadata: 5 | name: kong 6 | annotations: 7 | konghq.com/gatewayclass-unmanaged: 'true' 8 | 9 | spec: 10 | controllerName: konghq.com/kic-gateway-controller 11 | 12 | --- 13 | apiVersion: gateway.networking.k8s.io/v1 14 | kind: Gateway 15 | metadata: 16 | name: kong 17 | spec: 18 | gatewayClassName: kong 19 | listeners: 20 | - name: proxy 21 | port: 80 22 | protocol: HTTP 23 | 24 | --- 25 | apiVersion: configuration.konghq.com/v1 26 | kind: KongClusterPlugin 27 | metadata: 28 | name: global-cors 29 | annotations: 30 | kubernetes.io/ingress.class: kong 31 | labels: 32 | global: "true" 33 | config: 34 | origins: 35 | - '*' 36 | methods: 37 | - GET 38 | - POST 39 | headers: 40 | - Accept 41 | - Accept-Version 42 | - Content-Length 43 | - Content-MD5 44 | - Content-Type 45 | - Date 46 | - X-Auth-Token 47 | exposed_headers: 48 | - X-Auth-Token 49 | credentials: true 50 | max_age: 3600 51 | plugin: cors -------------------------------------------------------------------------------- /k8s/kong/values.yaml: -------------------------------------------------------------------------------- 1 | gateway: 2 | proxy: 3 | type: NodePort 4 | http: 5 | nodePort: 30000 6 | 7 | -------------------------------------------------------------------------------- /k8s/rabbitmq/rabbitmq.yaml: -------------------------------------------------------------------------------- 1 | apiVersion: rabbitmq.com/v1beta1 2 | kind: RabbitmqCluster 3 | metadata: 4 | name: rabbitmq 5 | spec: 6 | replicas: 1 7 | rabbitmq: 8 | additionalConfig: | 9 | default_user=guest 10 | default_pass=guest 11 | additionalPlugins: 12 | - rabbitmq_management 13 | - rabbitmq_stomp 14 | - rabbitmq_shovel 15 | - rabbitmq_shovel_management 16 | -------------------------------------------------------------------------------- /k8s/saga/.helmignore: -------------------------------------------------------------------------------- 1 | # Patterns to ignore when building packages. 2 | # This supports shell glob matching, relative path matching, and 3 | # negation (prefixed with !).
