Permanent Environments live on forever, but Ephemeral Environments—by definition—are meant to be temporary. By default, Ephemeral Environments will only last for 7 days in Release. If you need your environments to last longer this, you can upgrade to a premium plan and gain access to Permanent Environments, or perform the following actions to override the expiration and extend the life span beyond the default.
For all plans, you can extend the Environment life by clicking the EXTEND button on the Environment Details screen (shown below) which will renew the expiration for up to 7 days. Release will send you a notification email 24 hours before your environment expires to remind you that it will expire.
For premium plans, you have greater control over Ephemeral Environment expiration. In the global Account Settings, you can switch the "Destroy ephemeral environments after no activity" feature off which basically makes your Ephemeral Environments into long-lived spaces that need to be manually deleted. However, we recommend that most customers not do this because it can fill up their clusters (or their environment quotas) rather quickly with stale environments. Instead, if you leave it on, then you can specify how many days an Ephemeral Environment will last before it is destroyed. Most customers find that between 7-14 days is a good tradeoff for retention and space.
In some cases, you may want an Ephemeral Environment to persist for a much longer period of time, maybe for a sales demo or a really large overhaul of your product. In this type of scenario, we allow you to customize the expiration when you manually create a single environment. For example, on the Environments List screen, you can click the CREATE ENVIRONMENT button and a modal will appear. Open the Advanced Options toggle and you'll see the Environment Persistence settings.
