langfuse

Experimental Langfuse chart

See values.yaml for the chart values. They are subject to change!

Installation

helm install langfuse-demo https://ilyannn.github.io/charts/langfuse -f langfuse-values.yaml

Config-Free Installation

The default values set up the bundled Postgres, and the chart takes care of and setting up the authentication between the database and the service.

The Postgres password will be generated and saved in a Secret (in the example above, named langfuse-demo-postgres-secret).

Connecting to an Existing Database

If the bundled chart is disabled, one can authenticate to an existing database using the databaseURL value:

postgresql:
  enabled: false

databaseURL: "postgresql://some-existing-url"

Accessing the Installation

The chart comes with an ingress that can be set up with

ingress:
  enabled: true
  hosts: ...
  tls: ...

Additional Options

Any options not available in the values file can be manually put into a Secret and passed in the secrets.additional value:

secrets:
  additional:
    - my-github-options
    - my-google-options
    - ...

You should create the secrets before installing the chart:

kubectl create secret generic my-github-options \
  --from-literal=AUTH_GITHUB_CLIENT_ID=... \
  --from-literal=AUTH_GITHUB_CLIENT_SECRET=...

This can also be used to avoid providing databaseURL in plaintext:

postgresql:
  enabled: false

secrets:
  additional:
    - my-postgres-connection # field name is DATABASE_URL

Notes on Uninstalling

The usual helm uninstall RELEASE_NAME should work, but note that the following objects are not deleted automatically with the default values:

• the data PVC of the postgres subchart (if the subchart was enabled)
• the -postgres-secret secret (if the subchart was enabled, controlled by secrets.postgresql.keepWhenUninstalled)
• the -internal-secret secret (controlled by secrets.internal.keepWhenUninstalled)

This means that you can reinstall the chart and continue accessing the same data.
