#3775 [BUG] ImageSpec not leveraging build cache for basic example Issue created by jeevb Describe the bug Repeated invocations of

pyflyte run

involving

ImageSpec

rebuild python and apt dependencies from scratch instead of leveraging cache. Expected behavior When an `ImageSpec`definition is not updated, image rebuilds should reuse cached layers where possible to speed up build times. Additional context to reproduce 1. Create a script,

wf.py

with the following contents:

from flytekit import task, workflow, ImageSpec

image = ImageSpec(
    packages=["smart-open[gcs]"],
    apt_packages=["git"],
)


@task(container_image=image)
def my_task() -> str:
    return "hello, world!"


@workflow
def my_wf() -> str:
    return my_task()

2. Run the following command multiple times:

pyflyte run --remote wf.py my_wf
