Based on the knowledge sources, yes, you can leave

global.image.registry

blank if you want to use Airbyte's default public Docker repository. According to the [custom image registry documentation](https://docs.airbyte.com/platform/1.8/deploying-airbyte/integrations/custom-image-registries#step-1-customize-airbyte-to-use-your-image-registry), the

global.image.registry

configuration is only needed when you want to pull images from a custom image registry rather than Airbyte's public Docker repository. The documentation shows that to use a custom registry, you would add:

yaml global:   image:     registry: <http://ghcr.io/NAMESPACE|ghcr.io/NAMESPACE>

If you don't specify this configuration (or leave it blank), Airbyte will default to pulling images from [Airbyte's public Docker repository](https://hub.docker.com/u/airbyte), which is the standard behavior. So for your Helm V1 upgrade to version 2.0.0, you only need to set: -

global.version: "2.0.0"

-

global.image.tag: "2.0.0"

And you can omit or leave

global.image.registry

blank to use the default public registry.

Based on the knowledge sources, this error is a known issue that occurs when upgrading Airbyte versions with Helm charts. The error

couldn't find key CONNECTOR_REGISTRY_SEED_PROVIDER in ConfigMap

indicates that a required configuration key is missing from the ConfigMap. This is similar to other ConfigMap key issues documented in the knowledge sources, such as the [

JOB_KUBE_MAIN_CONTAINER_IMAGE_PULL_SECRET

issue](https://github.com/airbytehq/airbyte/issues/52034) and the [

JOB_KUBE_CONNECTOR_IMAGE_REGISTRY

issue](https://github.com/airbytehq/airbyte/issues/53215) that occurred in earlier version upgrades. ## Solution To resolve this issue, you need to explicitly add the

CONNECTOR_REGISTRY_SEED_PROVIDER

configuration to your values.yaml file. Based on the [environment variable list](https://github.com/airbytehq/airbyte/issues/65129), this variable should be included in the ConfigMap. Add the following to your values.yaml under the appropriate section (likely under

env_vars

or similar, depending on your Helm V1 configuration):

yaml env_vars:   CONNECTOR_REGISTRY_SEED_PROVIDER: "cloud"  # or your preferred value

The typical value for

CONNECTOR_REGISTRY_SEED_PROVIDER

is

"cloud"

for standard deployments, which tells Airbyte to use the cloud-based connector registry. Important note: This type of issue highlights why Airbyte is moving to Helm chart V2. As mentioned in the [Helm V2 upgrade documentation](https://docs.airbyte.com/platform/deploying-airbyte/chart-v2-community): > The new Helm chart has broader and more detailed options to customize your deployment. In most cases, it's no longer necessary to specify environment variables in your

values.yaml

file because the chart offers a more detailed interface for customization. Since you're on version 2.0.0 (the last version supporting Helm V1), you may encounter more of these missing key issues. I strongly recommend planning your migration to Helm chart V2 soon to avoid these configuration problems in future upgrades.

Based on the knowledge sources, yes, you can upgrade to Helm chart V2 using your existing "airbyte" namespace instead of creating a new "airbyte-v2" namespace. The documentation explicitly addresses this scenario. According to the [Helm V2 upgrade guide](https://docs.airbyte.com/platform/deploying-airbyte/chart-v2-community#how-to-upgrade), the recommendation to use a new namespace depends on whether you're using an external database: ## If you're using Airbyte's internal Postgres database: The documentation states: > If you're not using an external database, skip this step. At deployment time, you will reinstall Airbyte in your existing namespace. In this case, you would: 1. Uninstall Airbyte from your existing namespace (but do not delete the namespace) 2. Reinstall Airbyte with Helm V2 into the same namespace The [deployment instructions](https://docs.airbyte.com/platform/deploying-airbyte/chart-v2-community#deploy-airbyte) show this approach:

bash # Uninstall from existing namespace helm uninstall airbyte -n airbyte  # Reinstall with Helm V2 in the same namespace helm install airbyte airbyte-v2/airbyte \   --namespace airbyte \          # Same namespace as before   --values ./values.yaml \   --version 2.0.3 \   --set global.image.tag=1.7.0

## If you're using an external database: The documentation recommends using a new namespace to make troubleshooting easier, but it's not strictly required. The guide states: > It is possible to do a straight upgrade, but different Airbyte users have different and sometimes complex configurations that could produce unique and unexpected situations during the upgrade. By doing a fresh install, you create a separate environment that's easier to troubleshoot. Since you mentioned you're not utilizing Airbyte heavily, using your existing "airbyte" namespace should be fine, especially if you're using the internal database. Just make sure to backup your database first before proceeding with the upgrade.

Based on the knowledge sources, these errors are occurring because you're trying to use Airbyte 2.0.0 with Helm chart V1 (1.8.5), and certain environment variables that are expected in version 2.0.0 are not being set properly in your Helm V1 configuration. Here are the values you need to add to your

values.yaml

file for a community version deployment accessible only via cluster IP: ## Required Environment Variables Add these to your

values.yaml

under the

env_vars

section:

yaml env_vars:   AIRBYTE_URL: "<http://airbyte-airbyte-server-svc:8001>"  # Internal cluster service URL   STORAGE_BUCKET_AUDIT_LOGGING: ""  # Can be empty for community version

### Explanation: 1.

AIRBYTE_URL

: For cluster IP access only, this should point to your internal Kubernetes service. The default service name format is

airbyte-airbyte-server-svc

on port

8001

. If you're only accessing Airbyte within the cluster, this internal service URL is sufficient. 2.

STORAGE_BUCKET_AUDIT_LOGGING

: According to the [GitHub issue discussion](https://github.com/airbytehq/airbyte/issues/68136), users have successfully resolved this error by setting this variable. For the community version without audit logging enabled, you can either: - Set it to an empty string:

""

- Set it to your existing storage bucket if you're using external storage (e.g.,

"my-bucket"

or

"my-bucket/audit-logging"

) As one user in the [GitHub issue](https://github.com/airbytehq/airbyte/issues/68136) mentioned: > I solved this problem today! [...] I included the variable at the global level: >

yaml > global: >   env_vars: >     STORAGE_BUCKET_AUDIT_LOGGING: "my-bucket/audit-logging" >

Important: These workarounds are necessary because Helm chart V1 wasn't designed for Airbyte 2.0.0's configuration requirements. As I mentioned earlier, version 2.0.0 is the final version supporting Helm V1, and you're encountering these issues because the configuration structure has evolved. I strongly recommend planning your migration to Helm chart V2 to avoid these compatibility issues.
