Steps to run in docker

1. Clone repository

git clone https://github.com/kubAretip/spring-micro-websocket-chat.git

2. Configuration time

In this moment repositories with configuration files is public so you must remove configuration for privates repositories.
Go to config-server/src/main/resources open bootstrap-docker.yml and remove properties ignore-local-ssh-settings: , host-key-algorithm:, host-key: and private-key:
Go to docker folder and open .env.docker. Next fill REPO_BRANCH=master and GIT_REPO_URI=. Link to config repo below: https://github.com/kubAretip/spring-micro-websocket-chat-config
Go to docker folder and open docker-compose-docker.yml. In services section find config-server and remove environments variables: HOST_KEY: ${KNOWN_HOST_KEY}, PRIVATE_KEY: ${PEM}

3. Package

In spring-micro-websocket-chat run mvn clean package

4. Run

Inside docker folder run docker-compose -f docker-compose-docker.yml --env-file .env.docker up -d and ...
... wait a moment, docker compose builds the docker images and runs them.
You can access the application at http://localhost:8080
Documentation with application endpoints is available on http://localhost:8080/swagger-ui.html PS-1 If you don't see anything in Swagger UI, you must restart the gateway. It's happen because gateway has been in ready state before services, so gateway can't see Swagger endpoints from services. You can use Actuator to restart the gateway (POST http://localhost:8080/actuator/restart).
