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.

Procedure

1. Create a directory for OpenMetadata

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

mkdir openmetadata-docker && cd openmetadata-docker

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.

python3 -m venv env

3. Activate the virtual environment

source env/bin/activate

4. Upgrade pip and setuptools

pip3 install --upgrade pip setuptools

5. Install the OpenMetadata Python module using pip

pip3 install --upgrade "openmetadata-ingestion[docker]"

6. Ensure the module is installed and ready for use

metadata docker --help

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

❯ metadata docker --help
Usage: metadata docker [OPTIONS]

  Checks Docker Memory Allocation Run Latest Release Docker - metadata docker
  --start Run Local Docker - metadata docker --start -f path/to/docker-

Options:

  --stop                          Stops openmetadata docker containers
  --pause                         Pause openmetadata docker containers
  --resume                        Resume/Unpause openmetadata docker
                                  containers
  --clean                         Stops and remove openmetadata docker

  --ingest-sample-data            Enable the sample metadata ingestion
  --help                          Show this message and exit.

7. Start the OpenMetadata Docker containers

metadata docker --start

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:

metadata docker --start -db postgres

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.

✅  OpenMetadata is up and running

Open http://localhost:8585 in your browser to access OpenMetadata..

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

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:

mkdir openmetadata && cd "$_"
wget https://github.com/open-metadata/OpenMetadata/releases/download/{version}-release/docker-compose.yml
docker compose up -d

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.

❯ 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:

The docker command executed was `/usr/local/bin/docker compose --file /var/folders/bl/rm5dhdf127ngm4rr40hvhbq40000gn/T/docker-compose.yml --project-name openmetadata up --detach`.
It returned with code 1
The content of stdout can be found above the stacktrace (it wasn't captured).
The content of stderr is 'Network openmetadata_app_net  Creating
Network openmetadata_app_net  Error
failed to create network openmetadata_app_net: Error response from daemon: Pool overlaps with other one on this address space

A common solution is to run docker network prune:

WARNING! This will remove all custom networks not used by at least one container.

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

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.
