This might not help you but to the very best of my knowledge localstack can operate over the network just fine and I am pretty sure it has a reset endpoint for zeroing its state (I think it's this https://github.com/localstack/localstack/blob/v4.4.0/localstack-core/localstack/services/internal.py#L70-L71 https://github.com/localstack/localstack/blob/v4.4.0/localst... ) The other alternative is that I've seen folks mention systemd-nsspawn as a form of isolation if that's what your using docker for (but I've never tried it myself)
