feature #34131 [FrameworkBundle] Remove suffix convention when using env vars to override secrets from the vault (nicolas-grekas)
This PR was merged into the 4.4 branch. Discussion ---------- [FrameworkBundle] Remove suffix convention when using env vars to override secrets from the vault | Q | A | ------------- | --- | Branch? | 4.4 | Bug fix? | no | New feature? | no | Deprecations? | no | Tickets | - | License | MIT | Doc PR | - Right now, env vars that override encrypted secrets must en up with `_SECRET`. This PR removes this convention. It also enforces that only vars defined in the vault can be overriden locally. This means one cannot set a local-only secret.
