I have a docker instance setup from which I am using moviepy.editor.VideoFileClip to edit urls that come from a google cloud instance.
Locally, I have no problem doing this at all and can run:
from moviepy.editor import VideoFileClip
vfc = VideoFileClip('https://storage.googleapis.com/<bucket>/<mp4 name>')
...
However, in the docker instance, I am having problems accessing the file via moviepy, with the error:
Failed to resolve hostname storage.googleapis.com: Name or service not known
In the same python shell, i can run:
import urllib.request
urllib.request.urlretrieve('https://storage.googleapis.com/<bucket>/<mp4 name>', '/tmp/file.mp4')
And it works perfectly. Any idea what's going wrong?
