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.

OSX and Linux

Python (version 3.7, 3.8 or 3.9)

To check the version of Python you have, use the following command:

Docker (version 20.10.0 or greater)

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.

Docker Compose (version v2.1.1 or greater)

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.

Install Docker Compose Version 2.0.0 on Linux

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

Windows

WSL2, Ubuntu 20.04, and Docker for Windows

• 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 priviledge to install packages, if not, please use Super User.)

Procedure

1. Create a directory for OpenMetadata

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

2. Create a Python virtual environment

Create a virtual environment to avoid conflicts with other Python environments on your host system. A virtual environment is a self-contained directory tree that contains a Python installation for a particular version of Python, plus a number of additional packages.

In a later step you will install the openmetadata-ingestion Python module and its dependencies in this virtual environment.

3. Activate the virtual environment

4. Upgrade pip and setuptools

5. Install the OpenMetadata Python module using pip

6. Ensure the module is installed and ready for use

After running the command above, you should see output similar to the following.

7. Start the OpenMetadata Docker containers

This will create a docker network and four containers for the following services:

• MySQL to store the metadata catalog
• Elasticsearch to maintain the metadata index which enables you to search the catalog
• Apache Airflow which OpenMetadata uses for metadata ingestion
• The OpenMetadata UI and API server

After starting the Docker containers, you should see an output similar to the following.

After starting the containers, metadata will launch Airflow tasks to ingest sample metadata and usage data for you to experiment with. This might take several minutes, depending on your system.

Running with Postgres

From 0.12, OpenMetadata also supports Postgres local deployment out of the box!

You just need to run:

Note that the option -db postgres needs to be passed to the other commands as well to locate the proper compose file.

8. Wait for metadata ingestion to finish

˚ Once metadata ingestion has finished and the OpenMetadata UI is ready for use, you will see output similar to the following.

Log in to Airflow

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

Go on a tour and start discovering the power of metadata & collaboration

Log in to OpenMetadata

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
• Password: admin

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

Security

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

Advanced

If you want to persist your data, prepare Named Volumes for the containers.

Next Steps

1. Visit the Features overview page and explore the OpenMetadata UI.
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.

Troubleshooting

Compose is not a docker command

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.

metadata CLI issues

Are you having trouble starting the containers with the metadata CLI? While that process is recommended, you can always run docker compose manually after picking up the latest docker-compose.yml file from the release:

This snippet will create a directory named openmetadata and download the docker-compose.yml file automatically. Afterwards, it will start the containers. If instead you want to download the file manually to another location, you can do so from the Releases page.

This will start all the necessary components locally. You can validate that all containers are up and running with docker ps.

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

Network openmetadata_app_net Error

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.

Connect to a Container from the Host

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

After upgrading OpenMetadata version

If you're running the metadata docker --start after updating the openmetadata-ingestion package to a newer OpenMetadata release, you might encounter issues. For example, java.lang.ClassNotFoundException: org.openmetadata.service.security.NoopAuthorizer when updating from 0.11.

Then, you'll need to first run metadata docker --clean. It will clean/prune the containers, volumes, and networks, and download the newest docker compose file from the release. Note that this will get rid of the data. If you want to keep it, you will need to Backup your data. This command is required after each time you want to update your quickstart deployment of OpenMetadata with a new release to pick up the new compose file.
