Streaming Node.js HTTP Down- and Upload Example in Docker Container
A simple Node.js HTTP multipart scalable download/upload file server, running in a Docker Container or on IBM Bluemix Container Service using Docker volumes.
I added a Angular Webapplication to list files and test the upload and download from the Browser as well, this is based on the following examples and articles:

Local Test
clone repo and build and test the Docker Image locally
git clone https://github.com/cloud-dach/StreamingHTTPDocker.git
cd StreamingHTTPDocker
docker build -t "streaminghttpdocker" .
docker run -d -p 8000:8000 -v /var/www:/var/www streaminghttpdocker test the multipart upload with curl
curl -i -X POST -H "Content-Type: multipart/form-data" -F "data=@filename" http://localhost:8000/upload test the multipart download with wget
wget http://localhost:8000/download/filename Accessing the Webapplication in the Browser
http://localhost:8000/
Running it on IBM Bluemix using Container Scalabale Group
do a cf login and cf ic init
cf login ...
cf ic init ...tag local image in your remote registry on Bluemix
docker tag streaminghttpdocker registry.ng.bluemix.net/[YOURBLUEMIXNAMESPACE]/streaminghttpdockerpush the image to Bluemix
docker push registry.ng.bluemix.net/[YOURBLUEMIXNAMESPACE]/streaminghttpdockernow create a docker volume for storing files
cf ic volume create [YOURVOLUME]Now we create a scalabale group with 2 instances and bind it to on URL. The exposed port in the container of 8000 will be accessible on HTTPS 443 and your chosen URL. In that case you don't need to assign a public IP like for a single container.
https://www.ng.bluemix.net/docs/containers/container_cli_reference_cfic.html
This example will start 2 instances a 256MB bind a volume to the container path given in Dockerfile and has autorecovery on and will have an URL of https://[YOURHOSTNAME].eu-gb.bluemix.net.
Please adopt your Bluemix region domains!
cf ic group create -p 8000 -m 256 -v [YOURVOLUME]:/var/www --min 2 --auto --hostname [YOURHOST] -d eu-gb.mybluemix.net --name mygroup registry.eu-gb.bluemix.net/[YOURBLUEMIXNAMESPACE]/streaminghttpdocker:latestNow you can test the multipart upload with curl on Bluemix
curl -i -X POST -H "Content-Type: multipart/form-data" -F "data=@filename" https://[YOURHOST].eu-gb.mybluemix.net/upload Test the multipart download with wget
wget https://[YOURHOST].eu-gb.mybluemix.net/download/filename Now you can store and retrieve files in sclabale way using Docker and Node.js.
