Yes, it is possible to use an external PostgreSQL database for the K8s Helm Airbyte deployment. To do this, you need to configure the

values.yaml

file with the appropriate settings. Here are the steps to follow: 1. Set

postgresql.enabled

to

false

to disable the internal PostgreSQL database. 2. Configure the

externalDatabase

section with your external PostgreSQL instance details, such as host, user, password, database, and port. Here's an example of how your

values.yaml

file should look like:

yaml postgresql:   enabled: false externalDatabase:   host: ${db_host}   user: ${db_user}   password: ${db_password}   database: ${db_name}   port: ${db_port}

Additionally, if you're using external DB secrets, provide them in

values.yaml

under the

global.database

section in the following format:

yaml database:     secretName: "myOctaviaSecret"     secretValue: "postgresql-password"     host: "<http://example.com|example.com>"     port: "5432"

And upgrade the chart by running:

helm upgrade -f path/to/values.yaml %release_name% airbyte/airbyte

Please note that the Helm charts are still in alpha, and there might be some issues. Make sure to review the [documentation](https://docs.airbyte.com/deploying-airbyte/on-kubernetes-via-helm) and [forum discussions](https://discuss.airbyte.io/t/2914) for more information and troubleshooting tips.

Is it also possible to store the all logs for airbyte in external storage like S3 bucket for k8s airbyte deployment with Helm? What values I need to add to values.yaml ?
