Spring Boot Micrometer sample project

This project is meant as sandbox for experiments and sample implementation for Spring Boot 2 with Micrometer.

The state of this repository is still work in progress, but should run without issues.

Requirements (Run)

• Docker / Docker Compose (RAM 4 GB min.)

Requirements (Dev)

• Java JDK 11
• Node.js 8

Introductions

• Concepts of Micrometer
• Spring Boot Supported Metrics

Run complete monitoring environment

Step 1

./start_complete_stack.sh

This script will do the steps via Docker ...

• start and configured all monitoring products like (Elasticsearch, Kibana, Prometheus, ...).
• build and start the Vue.js Frontend frontend project.
• build and start the Spring Boot backend project.

Step 2

Open application via browser

This script will do the steps via Docker ...

• stop and remove all docker containers.
• remove all created docker volumes.

Dev hints

Stop and destroy all containers with its volumes manually

docker-compose stop && docker-compose rm -f -v
docker volume remove spring-boot-micrometer-sample_elasticsearch_data
docker volume remove spring-boot-micrometer-sample_grafana_data
docker volume remove spring-boot-micrometer-sample_prometheus_data
docker volume remove spring-boot-micrometer-sample_kibana_data

Rebuild one container

docker-compose up -d --no-deps --build grafana

Start dev docker-compose

docker-compose -f docker-compose-dev.yml up -d --force-recreate --build
