This is not at all a suggested way because we are disabling one of the angular features. We can bump that up using the max_old_space_size flag. For larger projects, we can add a ceiling of as much as 12-14 GB, considering the project is large enough. You can mitigate the risk of system instability due to OOME by: Docker can enforce hard memory limits, which allow the container to use no more By clicking Sign up for GitHub, you agree to our terms of service and container has.
