This is a Python library that you can import in your build, deployment and errand scripts to make it slightly easier to get variables in and out of Escape and perform common tasks such as executing a script in a Kubernetes pod. This library is mainly used by Ankyra itself to produce releases.
Here's an example from the extension-docker:
name: extension-docker
version: 0.5.@
logo: logo.png
description: ...
depends:
- stdlib-latest
build: build_and_push_image.py
The release depends on stdlib like a regular Escape package, which means that
it gets downloaded and unpacked (under ./deps/_/stdlib) at build and deploy
time - if it's not already there. Because Python won't regularly search this
path, we need to make sure to tell Python about it before we can finally import
the escape library:
#!/usr/bin/env python
import json
import os
import subprocess
import sys
sys.path = ["deps/_/stdlib"] + sys.path
import escape
docker_image = escape.get_string_input('docker_image')
docker_image_version = escape.get_string_input('docker_image_version')
We agree this is not the most elegant solution, but we didn't want to mess
with the user's python path. If this is not a concern you can install the library
into a proper place using a pre_build and pre_deploy step.
