Cloud-init's conversion of user-data to mime fails when the user-data is
base64 encoded due to the Python2 to Python3 switch. base64.b64decode in
Python 2 returns a string, whilst Python3 returns a byte stream.
Consider:
import base64
hi = "aGkK"
print(type(base64.b64decode(hi)).__name__)
if 'hi' in str(base64.b64decode(hi)):
print("works")
if 'hi' in base64.b64decode(hi):
print("works on Py2")
ben@prongs:~$ python /tmp/proof.py
str
works
works on Py2
ben@prongs:~$ python3 /tmp/proof.py
bytes
works
Traceback (most recent call last):
File "/tmp/proof.py", line 10, in <module>
if 'hi' in base64.b64decode(hi):
TypeError: Type str doesn't support the buffer API
