Images Web Server

Images Web Server is an example app written in Python used on Docker classes. The app serves images.

Setup

Requriements

Install module dependenices with PIP:
pip3 install -r requirements.txt

The following modules (and their dependencies) will be installed:

  • Bottle
  • requests
  • gunicorn (for "production" environments)

Running the server

python3 app.py will run the server in development / debug mode using port 3000. You can open the site using http://localhost:3000/ .
gunicorn --bind 0.0.0.0:8000 --workers 3 app:app will run the server in "production" mode on port 8000.

Server modes

Non-proxy mode

By default the server serves *.jpg, *.jpeg and *.png image files found in the images folder.

Proxy mode

If an environment variable called IMAGE_SRV is found then the server tries to load the http://IMAGE_SRV/remote-images.txt file when starting up. If file is not found, the server exists. If the file is found then the images listed inside will be proxied on the page displayed by Images Web Server. The images should be available at http://IMAGE_SRV/filename.ext.

remote-images.txt file format

image_file1.jpg
image_file2.png
