Pure Docker Run Commands for the Sample Application

Create a network that is called demo-network:

docker network create demo-network

Deploy Log Aggeration & Filtering Infrastructure

Following services are used to aggregate and filter the logs of running containers:

- Fluentd        #  Aggregate logs and push them to Elasticsearch
- Elasticsearch  #  Store log data
- Kibana         #  Visualize logs

Deploy Elasticsearch:

docker volume create --name elasticsearch_data
docker run -p 9200:9200 -d --network=demo-network \
            --name elasticsearch \
            -v elasticsearch_data:/usr/share/elasticsearch/data \
            --restart=on-failure \
            -e ES_JAVA_OPTS="-Xms512m -Xmx512m" \
            -e discovery.type="single-node" \
            docker.elastic.co/elasticsearch/elasticsearch:7.2.0

Deploy Fluentd:

docker run -p 24224:24224 -d --network=demo-network \
            --name fluentd \
            --restart=on-failure \
            cunal/fluentd:v1.6-debian-1-elasticsearch

Deploy Kibana:

docker run -p 5601:5601 -d --network=demo-network \
            --name kibana \
            -e ELASTICSEARCH_HOSTS=http://elasticsearch:9200 \
            --restart=on-failure \
            --log-driver=fluentd --log-opt fluentd-address=localhost:24224 \
            kibana:7.2.0

Deploy the Application

Create a volume for MongoDB and run its container.

docker volume create --name mongodb_data
docker run -p 27017:27017 -d --network=demo-network \
            --name mongodb \
            -v mongodb_data:/data/db \
            --restart=on-failure \
            --log-driver=fluentd --log-opt fluentd-address=localhost:24224 \
            mongo:4.0.2

Run Backend:

docker run -d --network=demo-network \
            --name backend \
            -e MONGODB_URI="mongodb://mongodb:27017/sample-app" \
            -e JAVA_OPTS="-Dspring.profiles.active=local-docker -Xms125m -Xmx250m" \
            --restart=on-failure \
            --log-driver=fluentd --log-opt fluentd-address=localhost:24224 \
            cunal/demo-backend:6685333069ec622c9c314b95f6df6cf8cc02afe0

Run Redis:

docker volume create --name redis_data
docker run -p 6379:6379 -d --network=demo-network \
            --name redis \
            -v redis_data:/data \
            --restart=on-failure \
            --log-driver=fluentd --log-opt fluentd-address=localhost:24224 \
            redis:5.0.6

Run Gateway:

docker run -p 9091:80 -d --network=demo-network \
            --name gateway \
            -e DEMO_BACKEND_SERVICE="http://backend" \
            -e JAVA_OPTS="-Dspring.profiles.active=local-docker -Xms125m -Xmx250m" \
            -e ZIPKIN_BASE_URL="http://jaeger:9411" \
            -e REDIS_HOST="redis" \
            -e REDIS_PORT="6379" \
            -e RATE_LIMIT_ENABLED="true" \
            -e RATE_LIMIT_REPOSITORY="REDIS" \
            -e RATE_LIMIT=4 \
            -e RATE_LIMIT_REFRESH_INTERVAL="1" \
            --restart=on-failure \
            --log-driver=fluentd --log-opt fluentd-address=localhost:24224 \
            cunal/demo-gateway:6685333069ec622c9c314b95f6df6cf8cc02afe0

Run Frontend:

docker run -p 5000:80 -d --network=demo-network \
            --name frontend \
            -e REACT_APP_BACKEND_URI=http://localhost:9091/api/demo-backend \
            --restart=on-failure \
            --log-driver=fluentd --log-opt fluentd-address=localhost:24224 \
            cunal/demo-frontend:6685333069ec622c9c314b95f6df6cf8cc02afe0

Check everything is working properly:

docker ps
