How to start

1. run in background with build

docker-compose up --build -d

2. check websites Airflow: http://localhost:8080

user: airflow
password: airflow

Spark Master: http://localhost:8181

Postgres - Database airflow:

• Server: localhost:5432
• Database: airflow
• User: airflow
• Password: airflow

Jupyter Notebook: http://127.0.0.1:8888

Following command will show you the URLs of running servers with their tokens, which you can copy and paste into your browser.

docker logs -f docker-airflow-spark-jupyter-spark-1

Spark

Safely way to stop Spark container

docker stop $(docker-compose ps | grep spark | awk '{print $1}')

or using Docker Compose:

docker-compose ps | grep spark | awk '{print $1}'

실행방법

전제조건

• Docker Demon (Docker Desktop 이 로컬에 설치되어 있어야 합니다.)

1. 백그라운드에서 실행하려면 본 프로젝트 최상단 위치에서 다음 명령어를 실행시켜주세요

docker-compose up -d

2. 각 서버 접속해서 확인해주시면 됩니다. 각 서버가 올라오는데 시간이 걸릴 수 있으니 Docker Desktop 에서 로그 확인 하면서 실행해주시면 더욱 좋습니다.

Airflow: http://localhost:8080

user: airflow
password: airflow

Spark Master: http://localhost:8181

Postgres - Database Connection Test:

• Server: localhost:5432
• Database: airflow
• User: airflow
• Password: airflow

Jupyter Notebook: http://127.0.0.1:8888

주피터 노트북은 서버 로그를 통해 확인되는 토큰정보를 기입해주세요. 다음 명령어로 로그 확인해주시면 됩니다.

docker logs -f docker-airflow-spark-jupyter-spark-1

## 로그에서 다음과 같이 확인 되는 정보 중에서 ex) http://localhost:8888/?token=c8de56fa... 
## token 값 정보를 입력해주시면 됩니다.

스파크 서버 안전하게 종료하는 방법

도커 명령어로 종료하기

docker stop $(docker-compose ps | grep spark | awk '{print $1}')

아니면... Docker Compose 명령어로 종료하기

docker-compose ps | grep spark | awk '{print $1}'
