wait-for
./wait-for
is a script designed to synchronize services like docker containers. It is sh and alpine compatible. It was inspired by vishnubob/wait-for-it, but the core has been rewritten at Eficode by dsuni and mrako.
When using this tool, you only need to pick the wait-for
file as part of your project.
