1. daml-all-in-one available under tools/docker folder
2. The dockerized container should have the appropriate healthchecks
3. The ledger should be accesible from outside the container via the client libraries/rpc (whatever is applicable)
4. Readme within the aio folder mentioning how to build & run a daml ledger docker image
