Docker Install

These instructions explain how to run Feldera on a single machine in a configuration suitable for demos, development, and testing. For production use, or for developing parts of Feldera itself, Feldera supports other forms of deployment.

Install prerequisites

To run the demo, you will first need to install Docker and the Docker Compose plugin. If you don't already have them, install them one of these ways:

  • On Mac OS, Windows, or Linux, install Docker Desktop, which includes the Docker Compose plugin. If you're on Apple Silicon, we recommend enabling Rosetta for x86/amd64 emulation.

  • On Linux only, first install Docker Engine and the Docker Compose plugin.


    The plugin implements Docker Compose v2, invoked as docker compose. Feldera does not support the older Docker Compose v1, which was invoked with docker-compose (note the   versus - distinction).

    Then, follow the instructions to manage Docker as a non-root user.


    If you you only want root to manage Docker, you can prefix the docker compose command below with sudo.

You also need curl and a web browser such as Chrome or Firefox.

Start the demo

  1. Download the docker-compose.yml file that tells Docker Compose how to set up the demo's containers:

    curl -LO

    You only need to do this the first time.


    This will replace any existing file named docker-compose.yml in the current directory.

  2. Launch containers for the demo, including the pipeline manager, Postgres to support it, and a SecOps demo that uses Redpanda. From the directory where you ran the command above:

    docker compose --profile demo up

    This command takes over the terminal where you run it as long as the demo is active. It will print a lot of log messages, which can be useful for debugging if something goes wrong but which otherwise are not important.

    The first time you run this command, it will download container images, which can take a while. Once docker compose begins bringing up the images, it takes about 10 seconds for the Feldera user interface to become available. On fast systems, this includes a pause of a few seconds in which nothing is logged.

  3. Visit http://localhost:8080/ in your web browser to bring up the Feldera Console UI.

  4. Try out one of the demos.

Stop the demo

To shut down the demo, type Ctrl+C in the terminal where docker compose is running. Docker Compose will show its progress as it shuts down each of the containers in turn. It can take up to about 15 seconds to complete shutdown.

Restart the demo

If you start and then stop the demo as described above, you can restart it a few different ways:

  • To restart it without changes, run:

    docker compose up
  • Run this command to reload the demo afresh, while discarding all additional programs, connectors and pipelines you've added:

    docker compose --profile demo up
  • Run this command to upgrade to a new version of the demo, while discarding all additional programs, connectors and pipelines you've added:

    docker compose --profile demo up --pull always --force-recreate -V


If the demo fails to start after it previously ran successfully, then it might not have fully shut down from the previous run. To ensure that it is fully shut down, run the following command, and then try starting it again:

docker compose --profile demo down

If starting the demo fails with bind: address already in use, then something on your machine is already listening on one of the ports required for the demo. The message should say the particular port. To correct the problem, find and stop the process listening on the port, or edit a copy of docker-compose.yml to use a different port number.
