@ancient-wolf-19325 I am deploying Flyte using Helm on k8s. I already have a database secret (it was created by automation software that deployed the database). What is the best way to reverence this secret?
a
To reference an existing database secret in Flyte when deploying using Helm, you can configure the Helm values file to point to your pre-created K8s secret. This approach avoids creating a new secret and instead leverages the one already created by your automation software. According to the Flyte Helm chart documentation, you can reference an external secret by setting the appropriate values in the 
values.yaml
file. Here's how you can do it: 1. Create the Secret: Ensure your secret is already created in Kubernetes. For example, if your secret is named 
db-password
, it might look something like this:
Copy code
apiVersion: v1
    kind: Secret
    metadata:
      name: db-password
      namespace: flyte
    type: Opaque
    stringData:
      pass.txt: <DB_PASSWORD>
2. Update 
values.yaml
: Reference this secret in your 
values.yaml
file under the 
common.databaseSecret
section:
Copy code
common:
      databaseSecret:
        name: db-password
3. Deploy Flyte: Apply the Helm chart with the updated 
values.yaml
file:
Copy code
helm upgrade --install flyte flyteorg/flyte -f values.yaml
This configuration will ensure that Flyte uses the existing 
db-password
secret for database credentials. Would you like more detail on this approach? Sources: - Add support for leveraging pre-created secrets in flyte-binary helm chart 👍 0 button 👎 0 button 💡 Hint: Mention @runllm in the thread for followups.

@ancient-wolf-19325 what if my secret has separate keys for host, password, etc.?
a
If your pre-created secret contains separate keys for database host, password, and other credentials, you can reference these individual keys in the Flyte Helm chart. Here's how you can configure it: 1. Create the Secret: Ensure your secret includes separate keys for each credential. For example:
Copy code
apiVersion: v1
    kind: Secret
    metadata:
      name: db-credentials
      namespace: flyte
    type: Opaque
    stringData:
      host: <DB_HOST>
      username: <DB_USERNAME>
      password: <DB_PASSWORD>
2. Update 
values.yaml
: Reference each key in your 
values.yaml
file. You can use the 
additionalVolumes
and 
additionalVolumeMounts
to mount the secret and then reference the individual keys:
Copy code
common:
      additionalVolumes:
        - name: db-credentials
          secret:
            secretName: db-credentials
      additionalVolumeMounts:
        - name: db-credentials
          mountPath: /etc/db-credentials

    flyteadmin:
      config:
        database:
          hostPath: /etc/db-credentials/host
          usernamePath: /etc/db-credentials/username
          passwordPath: /etc/db-credentials/password
3. Deploy Flyte: Apply the Helm chart with the updated 
values.yaml
file:
Copy code
helm upgrade --install flyte flyteorg/flyte -f values.yaml
This configuration mounts the 
db-credentials
secret and references the individual keys for the database configuration. Would you like more detail on this approach?

@ancient-wolf-19325 this way secrets are not mounted to init containers, so Flyte pods cannot be initialized. Is there a way to make secrets available to init containers?
a
To ensure that secrets are available to init containers in Flyte, you need to configure the Helm chart to mount the secrets in both the main containers and the init containers. This can be done by specifying the 
additionalVolumes
and 
additionalVolumeMounts
in the 
values.yaml
file for both the main and init containers. Here's how you can achieve this: 1. Create the Secret: Ensure your secret includes separate keys for each credential. For example:
Copy code
apiVersion: v1
    kind: Secret
    metadata:
      name: db-credentials
      namespace: flyte
    type: Opaque
    stringData:
      host: <DB_HOST>
      username: <DB_USERNAME>
      password: <DB_PASSWORD>
2. Update 
values.yaml
: Reference each key in your 
values.yaml
file and ensure the secret is mounted in both the main and init containers:
Copy code
common:
      additionalVolumes:
        - name: db-credentials
          secret:
            secretName: db-credentials
      additionalVolumeMounts:
        - name: db-credentials
          mountPath: /etc/db-credentials

    flyteadmin:
      config:
        database:
          hostPath: /etc/db-credentials/host
          usernamePath: /etc/db-credentials/username
          passwordPath: /etc/db-credentials/password
      initContainers:
        - name: init-container
          volumeMounts:
            - name: db-credentials
              mountPath: /etc/db-credentials

    flytepropeller:
      initContainers:
        - name: init-container
          volumeMounts:
            - name: db-credentials
              mountPath: /etc/db-credentials
3. Deploy Flyte: Apply the Helm chart with the updated 
values.yaml
file:
Copy code
helm upgrade --install flyte flyteorg/flyte -f values.yaml
This configuration ensures that the 
db-credentials
secret is mounted in both the main and init containers, making the secrets available during the initialization phase. Would you like more detail on this approach?

@some-solstice-93243 what Helm chart are you using? is it flyte-binary or flyte-core?
s
@average-finland-92144 thanks for reaching out! I was using the flyte-core chart, trying to follow https://github.com/unionai-oss/deploy-flyte/tree/add-azure/environments/azure/flyte-core. I was using Crossplane, which I am still learning. Turns out it was a problem in my Crossplane resources implementation - I was not sure back then, so I was trying to have a sanity check here with the AI assistant. All good now :).
a
cool! any feedback you may have on those Terraform modules, please let me know 🙂

I can only say that they were a great help 🙂. I do not use Terraform directly, however Crossplane uses Terraform underneath in its providers. Just reading through those modules saved me probably days of work, as I am new to Azure and I have deployed Flyte only once before. So it was great documentaion, which held my hand through all the proces. Kudos!

awesome!
