Goals

Allow to easily to declare all prefixed environment variables to be excluded from caching as they are not build-time environment variables.

For example, you use Playwright for end-to-end tests and want to be able to easily configure test data by defining a bunch of PLAYWRIGHT_API_URL, PLAYWRIGHT_TESTCASE1_USER_NAME etc so they can be changed per environment (e.g. local and staging, or prodtest etc).

Now you need to define each item while using a syntax PLAYWRIGHT_* would make it easier.

Non-goals

Initial iteration wouldn't need to allow to exclude a particular prefixed environment variable using a syntax of !PLAYWRIGHT_TESTCASE1_USER_NAME etc.

Background

Avoid needing to define each entry that you want to passthrough and excluded for cache calculations.

Proposal

Allow to define environment similar to a glob match, by the use of * , e.g. PLAYWRIGHT_* or CI_* etc.
