Update serverless testing for load balancer fronting single proxy

    • Needed
    • Hide

      Evergreen scripts for serverless provisioning have been updated in mongodb-labs/drivers-evergreen-tools@577c905. The serverless-expansion.yml file generated by create-serverless.sh now has only two relevant expansions: SERVERLESS_URI and SERVERLESS_INSTANCE_NAME:

      • SERVERLESS_URI is the SRV URI to be used for all connections to the serverless instance. Drivers MUST still add the username and password when using this connection string.
      • SERVERLESS_INSTANCE_NAME is used by the delete-instance.sh script. Additionally, drivers MAY define SERVERLESS_INSTANCE_NAME before calling create-instance.sh if they do not want to use a randomly generated name.

      Drivers MUST update the Evergreen environment variables specified in the Atlas Serverless credentials Google Doc. Drivers that have previously implemented DRIVERS-1375 will note that only the SERVERLESS_DRIVERS_GROUP variable has changed. It now points to a new Atlas project, which is configured to provision serverless instances where the load balancer is backed by a single proxy.

      Revised guidelines for handling useMultipleMongoses in legacy and unified test runners are discussed in mongodb/specifications@1b471f1. To summarize, since the URI now points to a load balancer backing a single serverless proxy, useMultipleMongoses is ignored when testing against Atlas Serverless.

      Summary

      Serverless tests currently rely on two URIs to the same Serverless project:

      • MULTI_ATLASPROXY_SERVERLESS_URI points to a load balancer fronting multiple Atlas Proxy processes.
      • SINGLE_ATLASPROXY_SERVERLESS_URI points to a single Atlas Proxy process.

      After CLOUDP-100715, it will no longer be possible to directly connect to an Atlas Proxy. The proposed plan in CLOUDP-100717 is to enable projects for testing with a load balancer fronting one Atlas Proxy. But it will not be possible to have both URIs to the same Serverless project.

      Decide on a new strategy for testing Serverless, and update Serverless tests.

      Motivation

      Is this issue urgent?

      Yes. CLOUDP-100715 is planned to start soon and estimated to complete within 6 weeks.

      Is this ticket only for tests?

      Yes
