It seems like you're facing a couple of issues here. Let's break them down: 1.
Using a private Docker registry: Airbyte allows you to use custom connectors from a private Docker registry. You need to authenticate your Airbyte instance to your private Docker registry. This involves authenticating your local or CI environment (where you build your connector image) to be able to push images to your registry, and your Airbyte instance must be able to pull images from your registry. You can find more details in the [Airbyte documentation](
https://docs.airbyte.com/operator-guides/using-custom-connectors#2-authenticate-to-your-private-docker-registry). 2.
Adding a custom connector: Once you've authenticated to your private Docker registry, you can add your custom connector in Airbyte. This involves naming your custom connector, filling in the Docker full image name and Docker image tag, and optionally adding a link to the connector's documentation. You can find more details in the [Airbyte documentation](
https://docs.airbyte.com/operator-guides/using-custom-connectors#4-use-your-custom-docker-connector-in-airbyte). 3.
Kubernetes and security contexts: If you're running Airbyte on Kubernetes, you might need to create a
Secret
in Kubernetes that will host your authentication credentials. You also need to set the
JOB_KUBE_MAIN_CONTAINER_IMAGE_PULL_SECRET
environment variable on the
airbyte-worker
pod. The value must be the name of your previously created Kubernetes Secret. You can find more details in the [Airbyte documentation](
https://docs.airbyte.com/operator-guides/using-custom-connectors#for-kubernetes-airbyte-deployments). 4.
Issues with the Postgres destination connector: If you're having issues with the Postgres destination connector, it might be due to specific limitations or known issues with the connector based on how or where it is deployed. You can find more details in the [Airbyte documentation](
https://docs.airbyte.com/integrations/destinations/postgres#vendor-specific-connector-limitations). If you're still encountering errors, it would be helpful to have more specific details about the errors and your setup.
