Druid Docker

Druid Docker Image

Run a simple Druid cluster

docker pull druidio/example-cluster
docker run --rm -i -p 3000:8082 -p 3001:8081 -p 3090:8090 druidio/example-cluster

Wait a minute or so for Druid to start up and download the sample.

Build Druid Docker Image

To build the docker image yourself

git clone https://github.com/druid-io/docker-druid.git
docker build -t example-cluster docker-druid

Logging

You might want to look into the logs when debugging the Druid processes. This can be done by logging into the container using docker ps:

CONTAINER ID        IMAGE                     COMMAND                  CREATED             STATUS              PORTS                                                                                                                      NAMES
9e73cbfc5612        druidio/example-cluster   "/bin/sh -c 'export H"   7 seconds ago       Up 6 seconds        2181/tcp, 2888/tcp, 3306/tcp, 3888/tcp, 8083/tcp, 0.0.0.0:3001->8081/tcp, 0.0.0.0:3000->8082/tcp, 0.0.0.0:3090->8090/tcp   sick_lamport

And attaching to the container using docker exec -ti 9e73cbfc5612 bash logs are written to /tmp/:
