devshawn/node-image-manipulator repository overview

⁠Node Image Manipulator

A small node server which manipulates images it receives for use in a Docker demonstration. To set manipulation modes for the server, visit the modes⁠ page.

⁠Sending Images

The server is made to intercept .png images. We have a simple bash script to send an image:

./send-image.sh [hostname] [image.png] [renamed-image.png]

So, for example, if I used this command locally with an image node.png:

./send-image.sh http://localhost:9001 node.png node2.png

⁠Standalone Server

⁠Setup

To start up the server, clone the repository and run the following command in the project's root directory:

node server.js

This will start up a server running on port 9001 on localhost.

⁠Usage

This server accepts an image as binary data as part of a POST request.

As an example, node.png is included in the root directory. To get and receive the same file, you can run the following command:

curl --request POST --data-binary "@node.png" http://localhost:9001/ >> node2.png

⁠Docker Server

⁠Docker Hub

The image can be found on Docker Hub⁠.

⁠Build From Source

Clone the repository and run the following command in the project's root directory:

docker build -t node-image-manipulator .

This will build the image. You can now spin up a container:

docker run -d -p 9001:9001 node-image-manipulator

This will spin up a container running the web server on port 9001 on localhost.
