gridfileserv

This repository contains code for the answer to a question on Stackoverflow: How to handle video and image upload to storage servers?

gridfileserv implements a http server which uses either a directory or MongoDB GridFS to store files uploaded to it.

Installation

Recommended: Using docker-compose

$ git clone https://github.com/mwmahlberg/gridfileserv.git
Cloning into 'gridfileserv'...

$ cd gridfileserv/
$ docker-compose build
docker-compose build

The application is now accessible via http://localhost:4711.

For usage, see below.

Manually

First, you need to build the application

$ git clone https://github.com/mwmahlberg/gridfileserv.git
Cloning into 'gridfileserv'...
remote: Enumerating objects: 14, done.
remote: Counting objects: 100% (14/14), done.
remote: Compressing objects: 100% (12/12), done.
remote: Total 14 (delta 2), reused 11 (delta 2), pack-reused 0
Unpacking objects: 100% (14/14), done.
$ go build
[...]

Option 1: MongoDB GridFS storage

Next, you need a connection to a MongoDB instance. If you have Docker installed, you can simply run:

$ docker run -d --name mongotest -p 27017:27017 mongo
1d1492408639f5ef650b25357af7392f56a9b710b904a0831dc65db4396624c2

Note that the output on your machine will be different.

Last but not least, you need to start the application.

gridfileserv mongodb [-listen [[hostnameOrIp]:port]] [-url otherThanLocalhost:27017] [-user <mongodbUsername> [-pass <mongodbPassword>] ]

You can pass the -h flag for details.

For example:

$ path/to/gridfileserv mongodb -listen :4711
2019/10/19 19:54:36 Starting webserver on :4711

Option 2: Filesystem storage

gridfileserv file [-listen [[hostnameOrIp]:port]] [-base <path/to/file/repository>]

For example:

$ path/to/gridfileserv file -listen :4711 -base ./data
2019/10/19 19:54:36 Starting webserver on :4711

Usage
