Data engineering project sample.

• Docker
• Docker compose

The services must be started in that order:

1 - Minio

cd minio
docker-compose -f .\minio.yml up

2 - Airflow

cd airflow
docker-compose -f .\airflow.yml up

3 - Dremio

cd dremio
docker-compose -f .\dremio.yml up

1 - Minio

• http://127.0.0.1:9001/
• login: minio
• password: minio123

2 - Airflow

• http://localhost:8080/
• login: admin
• password: admin

3- Dremio

• http://localhost:9047/
• You must create the credentials on first access
• login: admin
• password: admin123

Airflow connection to Minio:

• Go to Admin > Connections.
• In connection type, put S3.
• In extra field, put:

{"aws_access_key_id": "<minio_access>", "aws_secret_access_key": "<minio_secret>", "host": "http://172.24.0.2:9000"}

• the 172.24.0.2 is the IP informed by minio when it starts! It may change in your environment. Run docker logs <minio_container> to see the true IP.

Dremio connection to Minio:

• Add a Amazon S3 Source.
• In General menu, select AWS Access Key and put the keys from Minio. Also, uncheck the encryption option.
• In Advanced Options menu, check "Enable compatibility mode" and add these 2 connection properties:

fs.s3a.path.style.access = true
fs.s3a.endpoint = 172.24.0.2:9000

• Once again, this IP 172.24.0.2 is informed by minio when it starts and may vary.
