Updating a pure-Docker Sourcegraph cluster

This document describes the exact changes needed to update a pure-Docker Sourcegraph cluster. Each section comprehensively describes the changes needed in Docker images, environment variables, and added/removed services. Always refer to this page before upgrading Sourcegraph, as it comprehensively describes the steps needed to upgrade, and any manual migration steps you must perform.

  1. Read our update policy to learn about Sourcegraph updates.
  2. Find the relevant entry for your update in the update notes on this page. If the notes indicate a patch release exists, target the highest one.

Patch releases:

v3.30 ➔ v3.31

Notes:

  • The built-in main Postgres (pgsql) and codeintel (codeintel-db) databases have switched to an alpine-based Docker image. Upon upgrading, Sourcegraph will need to re-index the entire database. All users that use our bundled (built-in) database instances must read through the 3.31 upgrade guide before upgrading.

Patch releases:

  • v3.29.1

Notes:

  • This upgrade adds a new worker service that runs a number of background jobs that were previously run in the frontend service. See notes on deploying workers for additional details. Good initial values for CPU and memory resources allocated to this new service should match the frontend service.

v3.27 ➔ v3.28

As a template, perform the same actions as the following diffs in your own deployment:

v3.26 ➔ v3.27

As a template, perform the same actions as the following diffs in your own deployment:

  • v3.27.3

Patch releases:

  • v3.26.1

As a template, perform the same actions as the following diffs in your own deployment:

Notes:

  • If you are connecting to an external Postgres database using SSL/TLS: Go 1.15 introduced changes to SSL/TLS connection validation which requires certificates to include a SAN. This field was not included in older certificates and clients relied on the CN field. You might see an error like x509: certificate relies on legacy Common Name field. We recommend that customers using Sourcegraph with an external database and connecting to it using SSL/TLS check whether the certificate is up to date.
  • Confirm that codeinsights-db-disk has the correct file permissions via the following command.
sudo chown -R 999:999 ~/sourcegraph-docker/codeinsights-db-disk/
