Multi-Container Docker Template (Flask, Elasticsearch, Kibana)
Run build.sh to spin up the containers using docker-compose.yml.
./build.sh
| URL | Service |
|---|---|
http://localhost:9200 |
Elasticsearch |
http://localhost:5601 |
Kibana |
http://localhost:5000 |
Flask |
Within other containers, Elasticsearch is accessed at http://elasticsearch:9200.
Instant Logging
If the Flask application in /web uses stdout to generate log messages, the output will be captured by Docker instantly due to PYTHONUNBUFFERED: 0 in docker-compose.yml. Running the following will allow you to view these dumped logs.
docker-compose logs -f web
Updates on File Change
Bind mounting /web, the Flask application directory, to the container in docker-compose.yml allows the container to access /web on the host file system. When the container starts, it will pick up changes to the mounted code files as they happen and update accordingly.
