6. lando rebuild
Motivation
The lando rebuild
command is used to rebuild your app from scratch while preserving data. This is useful when you want to recreate your development environment without losing any important data.
Arguments
There are no specific arguments required for the lando rebuild
command. However, it should be run in the root directory of your project.
