Setup Instructions

1. Create Docker Network

Create a custom Docker network for the weather monitoring setup:

docker network create "weather-monitoring"

2. Start Elasticsearch and Kibana Containers

Start the Elasticsearch, Kibana containers and connect them to the previously created Docker network:

docker run --name elasticsearch --network "weather-monitoring" -p 9200:9200 -d -m 1GB docker.elastic.co/elasticsearch/elasticsearch:9.0.0
docker run --name kibana --network "weather-monitoring" -p 5601:5601 -d docker.elastic.co/kibana/kibana:9.0.0

3. Retrieve Elasticsearch Credentials

When starting Elasticsearch for the first time, generate the elastic password and enrollment token. These credentials are shown only once at startup. If you need to regenerate them, run the following commands:

• Reset the password:

  docker exec -it elasticsearch /usr/share/elasticsearch/bin/elasticsearch-reset-password -u elastic

• Create the enrollment token for Kibana:

  docker exec -it elasticsearch /usr/share/elasticsearch/bin/elasticsearch-create-enrollment-token -s kibana

4. Store Elasticsearch Password as Environment Variable

Store the elastic password in an environment variable for later use:

echo 'export ELASTIC_PASSWORD="your_password"' >> ~/.bashrc
source ~/.bashrc

5. Copy SSL Certificate from Elasticsearch Container

Copy the http_ca.crt SSL certificate from the Elasticsearch container to your local machine:

docker cp elasticsearch:/usr/share/elasticsearch/config/certs/http_ca.crt .

6. Verify Elasticsearch with REST API Call

Make a REST API call to ensure the Elasticsearch container is running:

curl --cacert http_ca.crt -u elastic:$ELASTIC_PASSWORD https://localhost:9200

7. Complete Kibana Enrollment and Login

• Paste the enrollment token obtained earlier into Kibana.

• Press Enter and then execute the following command to get the verification code:

  docker exec -it kibana bin/kibana-verification-code

• Copy the verification code and paste it into the Kibana enrollment prompt.

• Log into Kibana using the elastic username and the previously stored password.

8. Create the Required Images

cd inside the following paths:

• "/Weather-Monitoring/Weather-Station"
• "/Weather-Monitoring/Base-Central-Station"
• "/Weather-Monitoring/Rain-Detector"

and run the following command in the terminal to create their images:

 mvn compile jib:dockerBuild

9. Start Other Containers Using Docker Compose

To simplify the management of all services (ZooKeeper, Kafka, weather stations, etc.), use the docker-compose.yaml file. This file includes configurations for the following services:

• ZooKeeper: Used for Kafka coordination.
• Kafka: The message broker for data streaming.
• Weather Stations: 10 instances of weather stations, each sending data to Kafka.

docker compose up -d

10. Stopping Everything

To stop all running containers, run:

docker container stop elasticsearch kibana
docker compose down

11. Starting Everything Again

To start all services again, run:

docker container start elasticsearch kibana
docker compose up -d

Then, just login with the elastic username and password.
