# vault-run-action.sh — Execute an action inside the ephemeral vault-runner container
|
||
|
|
#
|
||
|
|
# This script is the entrypoint for the vault-runner container. It runs with
|
||
|
|
# vault secrets injected as environment variables (GITHUB_TOKEN, CLAWHUB_TOKEN,
|
||
|
|
# deploy keys, etc.) and dispatches to the appropriate action handler.
|
||
|
|
#
|
||
|
|
# The vault-runner container is ephemeral: it starts, runs the action, and is
|
||
|
|
# destroyed. Secrets exist only in container memory, never on disk.
|
||
|
|
#
|
||
|
|
# Usage: vault-run-action.sh <action-id>
