To add a custom connector from a public Docker image in Docker Hub, follow these three easy steps: 1. Get the Docker coordinate of your custom connector from Dockerhub (or any image repository that Airbyte can access). 2. In the Airbyte UI, go to the Admin section, and click on

[+ New connector]

on the top right. 3. Fill in the display name, the Docker repository name (repository + image name), tag, and documentation URL for that connector. Once this is filled, you will see your connector in the UI, and your team will be able to use it, both from the UI and Airbyte's API [source](https://docs.airbyte.com/integrations/custom-connectors). If you want to make a small modification to the

destination-gcs

connector, you can follow these steps: 1. Clone the Airbyte repository and make your changes to the

destination-gcs

connector. 2. Build and tag your modified connector image locally, e.g.,

docker build . -t my-custom-destination-gcs:0.1.0

. 3. Push the image to Docker Hub or any public image repository. 4. Follow the steps mentioned above to add the custom connector to Airbyte using the Docker coordinate of your modified connector. This way, you can use your modified

destination-gcs

connector without using the connection builder.
