| # Documentation for `gcr.io/distroless/python3` | ||
|
|
||
| ## Image Contents | ||
|
|
||
| This image contains a minimal Linux, Python-based runtime. | ||
|
|
||
| Specifically, the image contains everything in the [base image](../../base/README.md), plus: | ||
|
|
||
| * Python 3 and its dependencies. | ||
| * No shell and no support for ctypes | ||
|
|
||
| ## Usage | ||
|
|
||
| The entrypoint of this image is set to "python", so this image expects users to supply a path to a .py file in the CMD. | ||
|
|
||
| See the Python [Hello World](../../examples/python3/) directory for an example. |
