Using a managed object storage service (S3 or GCS)

By default, Sourcegraph will use a MinIO server bundled with the instance to store precise code intelligence indexes uploaded by users. You can configure your instance to instead store this data in an S3 or GCS bucket. Doing so may decrease your hosting costs as persistent volumes are often more expensive than the same storage space in an object store service.

To target a managed object storage service, you will need to set a handful of environment variables for configuration and authentication to the target service. If you are running a sourcegraph/server deployment, set the environment variables on the server container. Otherwise, if running via Docker or Kubernetes, set the environment variables on the frontend and precise-code-intel-worker containers.

Using S3

To target an S3 bucket you've already provisioned, set the following environment variables. Authentication is done through an access and secret key pair (and optional session token).

  • PRECISE_CODE_INTEL_UPLOAD_BACKEND=S3
  • PRECISE_CODE_INTEL_UPLOAD_BUCKET=<my bucket name>
  • PRECISE_CODE_INTEL_UPLOAD_AWS_ACCESS_KEY_ID=<your access key>
  • PRECISE_CODE_INTEL_UPLOAD_AWS_SECRET_ACCESS_KEY=<your secret key>
  • PRECISE_CODE_INTEL_UPLOAD_AWS_SESSION_TOKEN=<your session token> (optional)
  • PRECISE_CODE_INTEL_UPLOAD_AWS_REGION=us-east-1 (default)

Using GCS

To target a GCS bucket you've already provisioned, set the following environment variables. Authentication is done through a service account key, supplied as either a path to a volume-mounted file, or the contents read in as an environment variable payload.

  • PRECISE_CODE_INTEL_UPLOAD_BACKEND=GCS
  • PRECISE_CODE_INTEL_UPLOAD_BUCKET=<my bucket name>
  • PRECISE_CODE_INTEL_UPLOAD_GCP_PROJECT_ID=<my project id>
  • PRECISE_CODE_INTEL_UPLOAD_GOOGLE_APPLICATION_CREDENTIALS_FILE=</path/to/file>
  • PRECISE_CODE_INTEL_UPLOAD_GOOGLE_APPLICATION_CREDENTIALS_FILE_CONTENT=<{"my": "content"}>

Provisioning buckets

If you would like to allow your Sourcegraph instance to control the creation and lifecycle configuration management of the target buckets, set the following environment variables:

  • PRECISE_CODE_INTEL_UPLOAD_MANAGE_BUCKET=true
  • PRECISE_CODE_INTEL_UPLOAD_TTL=168h (default)
