Statement

This procedure applies to regular releases of the centrally-provided production services that need to be fully built, tested and deployed.

This may be either:

  • a high risk/impact change needing careful testing
  • a set of linked changes to test and deploy together
  • lower priority changes bundled together to reduce downtime.
Dissemination Level

TLP:WHITE - Public

Overview

This procedure is meant to cover releases for which it is required to go through a complete planning/testing/deployment phase.

A Jira ticket coming from CHM is used to orchestrate the release and deployment, but in order to allow any participant to test and provide feedback during the testing phase a dedicated GGUS ticket is created.

Once the release will have been deployed the GGUS ticket will be closed, feedback will be added to the Jira ticket and re-assigned to CHM so that they can review it.

Definitions

Please refer to the EGI Glossary for the definitions of the terms used in this procedure.

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", “MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119.

Entities involved in the procedure

  • Change Owner: The person in charge of the change, following it through from initial planning to implementation and review. Initiates the Release procedure by marking a CHM ticket as ready to be released, assigning it to RDM.
  • Release Owner: The person in charge of the release, control and coordinate the activities in the lifecycle of a specific release.
  • RDM Staff: Support the Release Owner over all the process and may provide further people for testing the service or service component. Usually it is the SDIS team.
  • CRM Staff: Will be informed of the release so that they can interface with customers if needs be.

  • Service Supplier: Team responsible for the actual development, release and deployment of the service or service component.

  • NOC-Managers: Are informed regarding the release of the new service or service component and may provide further people for testing it.

  • Testers: Optional additional testers that are informed about the release and can test and provide feedback during the testing phase.
  • CAB: Change Advisory Board is a group of technical and strategic experts (membership decided by SSB) who are tasked with reviewing proposed change requests and reviewing them and approving or rejecting the changes.
