storage-upload

Docker micro service for uploading files to a storage server.

Usage

storage-upload listens on port 4020 by default. Since the storage upload needs a place to store the uploaded files, it's important to map the /app/public folder to either locally or some volume.

In addition it's recommended to also map the config file /app/config/config.production.json which should include a list of accepted sites and the corresponding json web token secret.

docker run -d \
  --name storage-upload \
  -v /path/to/store/files:/app/public \
  -v /path/to/config/file.json:/app/config/config.production.json \
  -p 4000:4020
  nfpis/storage-upload

Config

The config file should look something like this:

config.production.json

{
  "sites": {
    "site1": "site1-secret",
    "site2": "site2-secret"
  }
}

The server checks the token in the query for supported site name and then verifies the secret match. To generate a token valid to upload to site2 above, you can run something like this:

const jwt = require('jsonwebtoken')

let token = jwt.sign({ site: 'site2' }, 'site2-secret')
// eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzaXRlIjoic2l0ZTIifQ.Ovz7fnTMzaWOLOhnbkMtqHPk20EVqhCD8WDsLKk_Wv0

Hint: Post the above token to https://jwt.io/ and check it out.

Using the above token would save the requested file under /app/public/site2/ folder
