Get started with QuestDB via Docker

QuestDB has images for both Linux/macOS and Windows on Docker Hub.

Install Docker

Before we start, you will need to install Docker. You can find guides for your platform on the official documentation.

QuestDB image

Once Docker is installed, you will need to pull QuestDB's image from Docker Hub and create a container. You can do both in one command using docker run:

docker run -p 9000:9000 -p 8812:8812 questdb/questdb

Options

Argument	Description
-p	Port to publish to the host
-v	To bind mount a volume

-p parameter

This parameter will publish a port to the host, you can specify:

• -p 9000:9000: REST API and Web Console
• -p 8812:8812: Postgres
• -p 9009:9009: InfluxDB line protocol

-v volumes

The QuestDB root_directory will be in the following location:

Linux

/root/.questdb/db

Windows

C:\questdb\db

Container status

You can check the status of your container with docker ps. It also lists the ports we published:

docker ps

Result

CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

dd363939f261 questdb/questdb "/app/bin/java -m io…" 3 seconds ago Up 2 seconds 8812/tcp, 9000/tcp frosty_gauss

Importing data and sending queries

Now that QuestDB is running, you can start interacting with it:

• If you published the port 9000, you can follow our REST page
• If you published the port 8812, follow our Postgres page
• If you published the port 9009, follow our InfluxDB page

Data persistence

Restart an existing container

When you stop the container, it will not be removed by Docker. This means that you can restart it anytime and your data will be accessible:

Start container from the ID obtained with 'docker ps'

docker start dd363939f261

Re-run docker run

If you re-run the command:

docker run -p 9000:9000 -p 8812:8812 questdb/questdb

A new container will be created for the QuestDB image. This means that the container will be fresh, any data you may have created previously won't be accessible.
