Local Docker Deployment

This installation doc will help you start a OpenMetadata standalone instance on your local machine.

If you'd rather see the steps in a guided tutorial, we've got you covered! Otherwise, feel free to read the content below 👇

Requirements (OSX, Linux and Windows)

Please ensure your host system meets the requirements listed below. Then continue to the Procedure for installing OpenMetadata.

Docker is an open-source platform for developing, shipping, and running applications. It enables you to separate your applications from your infrastructure, so you can deliver software quickly using OS-level virtualization. It helps deliver software in packages called Containers.

To check the version of Docker you have, use the following command.

If you need to install Docker, please visit Get Docker.

You must allocate at least 6 GiB of memory and 4 vCPUs to Docker in order to run OpenMetadata. To change the memory allocation for Docker, please visit Preferences -> Resources -> Advanced in your Docker Desktop.

The Docker compose package enables you to define and run multi-container Docker applications. The compose command integrates compose functions into the Docker platform, making them available from the Docker command-line interface ( CLI). The Python packages you will install in the procedure below use compose to deploy OpenMetadata.

  • MacOS X: Docker on MacOS X ships with compose already available in the Docker CLI.
  • Linux: To install compose on Linux systems, please visit the Docker CLI command documentation and follow the instructions.

To verify that the docker compose command is installed and accessible on your system, run the following command.

Upon running this command you should see output similar to the following.

Follow the instructions here to install docker compose version 2.0.0

  1. Run the following command to download the current stable release of Docker Compose

    This command installs Compose V2 for the active user under $HOME directory. To install Docker Compose for all users on your system, replace ~/.docker/cli-plugins with /usr/local/lib/docker/cli-plugins.

  2. Apply executable permissions to the binary

  3. Test your installation

  • Install WSL2
  • Install Ubuntu 20.04
  • Install Docker for Windows
    • Once installed, please follow the steps here and complete all the pre-requisites for a seamless installation and deployment.
    • After completion of the pre-requisites, please install python3-pip and python3-venv on your Ubuntu system.
      • Command: apt install python3-pip python3-venv (Ensure that you have the privilege to install packages, if not, please use Super User.)

Create a new directory for OpenMetadata and navigate into that directory.

Download the docker-compose.yml file from the release page here.

The latest version is at the top of the page

  • Deploying with MySQL: Download docker-compose.yml file from the above link.
  • Deploying with PostgreSQL: Download docker-compose-postgres.yml file from the above link.

You can use the curl or wget command as well to fetch the docker compose files from your terminal -

Run the below command to deploy the OpenMetadata

For OpenMetadata with MySQL Database -

For OpenMetadata with PostgreSQL Database -

These commands will pull the docker images of Openmetadata for MySQL / PostgreSQL, OpenMetadata-Server, OpenMetadata-Ingestion and Elasticsearch.

Upon running this command you should see output similar to the following.

You can validate that all containers are up by running with command docker ps.

In a few seconds, you should be able to access the OpenMetadata UI at http://localhost:8585

By default, we ship Docker Compose with host and docker named volume mapping for MySQL, PostgreSQL, ElasticSearch and Ingestion Services with quickstart docker compose services. This will be available under docker-volume directory on host machine in the same path as docker compose files.

OpenMetadata provides a default admin account to login.

You can access OpenMetadata at http://localhost:8585. Use the following credentials to log in to OpenMetadata.

  • Username: admin@openmetadata.org
  • Password: admin

Once you log in, you can goto Settings -> Users to add another user and make them admin as well.

OpenMetadata ships with an Airflow container to run the ingestion workflows that have been deployed via the UI.

In the Airflow, you will also see some sample DAGs that will ingest sample data and serve as an example.

You can access Airflow at http://localhost:8080. Use the following credentials to log in to Airflow.

  • Username: admin
  • Password: admin

You can explore the examples of Airflow DAGs used with OpenMetadata. Refer here for more information.

From the same directory as mentioned in step 1, run the below command to stop the docker compose services and clean named volumes.

If you are getting an error such as "compose" is not a docker command, you might need to revisit the installation steps above to make sure that Docker Compose is properly added to your system.

You might see something like:

A common solution is to run docker network prune:

So be careful if you want to keep up some (unused) networks from your laptop.

You can connect Docker containers to communicate with Host Operating System Services. Navigate to the official docker documentation which will help achieve the same.

Please follow our Enable Security Guide to configure security for your OpenMetadata installation.

  1. Refer the How-to Guides for an overview of all the features in OpenMetadata.
  2. Visit the Connectors documentation to see what services you can integrate with OpenMetadata.
  3. Visit the API documentation and explore the rich set of OpenMetadata APIs.

If you are running on Windows (WSL2) and see permissions errors when starting the databases (either MySQL or Postgres), e.g.,

You can try to update the /etc/wsl.conf file from the WSL2 machine to add:
