Configuration server

Configuration server requires your GitHub username as well as GitHub token with access to repositories. Generate your token in your profile settings: https://github.com/settings/tokens

To start the config server, create .env file (config-server/src/main/resources/.env) and define the following two variables in order to access the repository:

GITHUB_USERNAME=your_github_username
GITHUB_TOKEN=your_github_token

Run using IntelliJ

Make sure to install all dependencies from all pom.xml files.

Order of running the services:

1. config-server
2. discovery
3. api-gateway
4. user-service
5. travel-service

Run using Docker

Create an .env file (config-server\src\main\resources.env) and set the following environment variables:

GITHUB_USERNAME=your_github_username
GITHUB_TOKEN=your_github_token

Set correct variables in properties files:

• In config-server: spring.cloud.config.server.git.uri=https://github.com/Microarchitecturovisco/cloud-project-configurations-for-docker.git
• • In user-service: spring.config.import=optional:configserver:http://config:8012
• In travel-service: spring.config.import=optional:configserver:http://config:8012

Then use the following command to build and run the services:

docker-compose up -d --build

Using Docker swarm

Begin with running the instructions mentioned above (section "Run using Docker"). Next:

1. Build Docker image for each service: ./build-images.sh

2. Initialize Docker swarm: docker swarm init

3. Run services defined in docker-compose.yml file: docker stack deploy --compose-file docker-compose-swarm.yml cloud-project

All the containers will start at the same time. However, user and travel services will wait until the discovery service is available and then these application will start. Number of replicas for each service can be specified in the docker-compose-swarm.yml file. In the current configuration there will be:

• 1 replica of config server
• 1 replica of discovery service
• 2 replicas of user service
• 2 replicas of travel service

4. Check the status of the services: docker service ls

5. To stop current stack use: docker stack rm cloud-project

6. To turn off the Docker swarm mode use this command: docker swarm leave --force
