.tiltignore allows you to tell tilt about file changes that should not cause Tilt to build your code.
Tilt looks for a file named
.tiltignore in the same directory as your
Tiltfile and parses it using the .dockerignore syntax. If a path is filtered by this file, it will not cause Tilt to build your code, but it is still eligible to be used as part of the docker build itself.
