When the merge request is first opened, an environment is provisioned, and when the merge request is closed, the environment is cleaned up. One of the hardest problems to solve when implementing Ephemeral Environments is considering when to create/destroy them.Ī classic approach is to tie the lifecycle to the life of a pull request or merge request. Migrated - The database uses the schema currently used in production, and has proposed migrations run against it: One of the most common classes of problems uncovered by ephemeral environments are broken or non-performant database migrations.
#DEFINE EPHEMERAL REGISTRATION#
This is also crucial for running destructive end-to-end tests that perform actions like registration and account deletion.
Undoable - If, in the course of a review, data is deleted or modified, it should be easy to reset the database to its original state.Prepopulated - it contains representative, anonymized data - to pass security audits, all Personally-Identifiable Information (PII) must be scrubbed from databases used by ephemeral environments.In the early implementation of ephemeral environments, it might make sense to connect API servers with read-only permissions to a staging database (e.g., via IAM roles if using AWS) - however, the end goal should be to have a fresh copy of the database for every commit.Īn ideal ephemeral database has three attributes: A reviewer should be able to try deleting a resource in a review without fear of affecting production. Databases in ephemeral environmentsīy their nature, ephemeral environments are temporary and should be isolated from production servers or data. Working with designers is easier if you have automatic per-branch ephemeral environments.
#DEFINE EPHEMERAL CODE#
Developers can review the results of changes visually, instead of needing to exclusively give feedback on the code change itself.Īdditionally, developers can share their work with non-technical collaborators such as designers as easily as sharing a link to the proposed revision.
#DEFINE EPHEMERAL SOFTWARE#
The most common reason to adopt an ephemeral environment workflow is that it accelerates the software development lifecycle. In general, ephemeral environments lie halfway between the development environments and staging environments - at the extreme, staging is entirely replaced with ephemeral environments in a Continuous Staging workflow. Ephemeral environments linked to GitHub pull requests Because these environments are made on every change, all stakeholders can review a change without needing a development environment. Temporary environments are overtaking traditional CI platforms as the most valuable DevOps paradigm for technical teams. They are often spun up by a Slack bot, or automatically on every commit using hosted DevOps platforms like webapp.io or Heroku. Ephemeral environments are temporary deployments that contain a self-contained version of your application, generally for every feature branch.
