Docker Quickstart

Use registry.gitlab.com/timvisee/send:latest from timvisee/send's Gitlab image registry for the latest Docker image.

docker pull registry.gitlab.com/timvisee/send:latest

# example quickstart (point REDIS_HOST to an already-running redis server)
docker run -v $PWD/uploads:/uploads -p 1443:1443 \
    -e 'DETECT_BASE_URL=true' \
    -e 'REDIS_HOST=localhost' \
    registry.gitlab.com/timvisee/send:latest

Or clone this repo and run docker build -t send:latest . to build an image locally.

Note: for Docker Compose, see: https://github.com/timvisee/send-docker-compose

Environment Variables

All the available config options and their defaults can be found here: https://github.com/timvisee/send/blob/master/server/config.js

Config options should be set as unquoted environment variables. Boolean options should be true/false, time/duration should be integers (seconds), and filesize values should be integers (bytes).

Config options expecting array values (e.g. EXPIRE_TIMES_SECONDS, DOWNLOAD_COUNTS) should be in unquoted CSV format. UI dropdowns will default to the first value in the CSV, e.g. DOWNLOAD_COUNTS=5,1,10,100 will show four dropdown options, with 5 selected by the default.

Server Configuration

Name	Description
BASE_URL	The HTTPS URL where traffic will be served (e.g. https://send.firefox.com)
DETECT_BASE_URL	Autodetect the base URL using browser if BASE_URL is unset (defaults to false)
PORT	Port the server will listen on (defaults to 1443)
NODE_ENV	Run in development mode (unsafe) or production mode (the default)
SEND_FOOTER_DMCA_URL	A URL to a contact page for DMCA requests (empty / not shown by default)
SENTRY_CLIENT, SENTRY_DSN	Sentry Client ID and DSN for error tracking (optional, disabled by default)

Note: more options can be found here: https://github.com/timvisee/send/blob/master/server/config.js

Upload and Download Limits

Configure the limits for uploads and downloads. Long expiration times are risky on public servers as people may use you as free hosting for copyrighted content or malware (which is why Mozilla shut down their send service). It's advised to only expose your service on a LAN/intranet, password protect it with a proxy/gateway, or make sure to set SEND_FOOTER_DMCA_URL above so you can respond to takedown requests.

Name	Description
MAX_FILE_SIZE	Maximum upload file size in bytes (defaults to 2147483648 aka 2GB)
MAX_FILES_PER_ARCHIVE	Maximum number of files per archive (defaults to 64)
MAX_EXPIRE_SECONDS	Maximum upload expiry time in seconds (defaults to 604800 aka 7 days)
MAX_DOWNLOADS	Maximum number of downloads (defaults to 100)
DOWNLOAD_COUNTS	Download limit options to show in UI dropdown, e.g. 10,1,2,5,10,15,25,50,100,1000
EXPIRE_TIMES_SECONDS	Expire time options to show in UI dropdown, e.g. 3600,86400,604800,2592000,31536000
DEFAULT_DOWNLOADS	Default download limit in UI (defaults to 1)
DEFAULT_EXPIRE_SECONDS	Default expire time in UI (defaults to 86400)

Note: more options can be found here: https://github.com/timvisee/send/blob/master/server/config.js

Storage Backend Options

Pick how you want to store uploaded files and set these config options accordingly:

• Local filesystem (the default): set FILE_DIR to the local path used inside the container for storage (or leave the default)
• S3-compatible object store: set S3_BUCKET, AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY (and S3_ENDPOINT if using something other than AWS)
• Google Cloud Storage: set GCS_BUCKET to the name of a GCS bucket (auth should be set up using Application Default Credentials)

Redis is used as the metadata database for the backend and is required no matter which storage method you use.

Name	Description
REDIS_HOST, REDIS_PORT, REDIS_USER, REDIS_PASSWORD, REDIS_DB	Host name, port, and pass of the Redis server (defaults to localhost, 6379, and no password)
FILE_DIR	Directory for storage inside the Docker container (defaults to /uploads)
S3_BUCKET	The S3 bucket name to use (only set if using S3 for storage)
S3_ENDPOINT	An optional custom endpoint to use for S3 (defaults to AWS)
S3_USE_PATH_STYLE_ENDPOINT	Whether to force path style URLs for S3 objects (defaults to false)
AWS_ACCESS_KEY_ID	S3 access key ID (only set if using S3 for storage)
AWS_SECRET_ACCESS_KEY	S3 secret access key ID (only set if using S3 for storage)
GCS_BUCKET	Google Cloud Storage bucket (only set if using GCP for storage)

Note: more options can be found here: https://github.com/timvisee/send/blob/master/server/config.js

Examples

Run using an Amazon Elasticache for the Redis DB, Amazon S3 for the storage backend, and Sentry for error reporting.

$ docker run -p 1443:1443 \
  -e 'S3_BUCKET=testpilot-p2p-dev' \
  -e 'REDIS_HOST=dyf9s2r4vo3.bolxr4.0001.usw2.cache.amazonaws.com' \
  -e 'SENTRY_CLIENT=https://51e23d7263e348a7a3b90a5357c61cb2@sentry.prod.mozaws.net/168' \
  -e 'SENTRY_DSN=https://51e23d7263e348a7a3b90a5357c61cb2:65e23d7263e348a7a3b90a5357c61c44@sentry.prod.mozaws.net/168' \
  -e 'BASE_URL=https://send.example.com' \
  registry.gitlab.com/timvisee/send:latest

Note: make sure to replace the example values above with your real values before running.

Run totally self-hosted using the current filesystem directry ($PWD) to store the Redis data and file uploads, with a 5GB upload limit, 1 month expiry, and contact URL set.

# create a network for the send backend and redis containers to talk to each other
$ docker network create timviseesend

# start the redis container
$ docker run --net=timviseesend -v $PWD/redis:/data redis-server --appendonly yes

# start the send backend container
$ docker run --net=timviseesend -v $PWD/uploads:/uploads -p 1443:1443 \
    -e 'BASE_URL=http://localhost:1443' \
    -e 'MAX_FILE_SIZE=5368709120' \
    -e 'MAX_EXPIRE_SECONDS=2592000' \
    -e 'SEND_FOOTER_DMCA_URL=https://example.com/dmca-contact-info' \
    registry.gitlab.com/timvisee/send:latest

Then open http://localhost:1443 to view the UI. (change the localhost to your IP or hostname above to serve the UI to others)

To run with HTTPS, you will need to set up a reverse proxy with SSL termination in front of the backend. See Docker Compose below for an example setup.

Run with custom branding.

$ docker run -p 1443:1443 \
    -v $PWD/custom_assets:/app/dist/custom_assets \
    -e 'UI_COLOR_PRIMARY=#f00' \
    -e 'UI_COLOR_ACCENT=#a00' \
    -e 'UI_CUSTOM_ASSETS_ICON=custom_assets/logo.svg' \
    registry.gitlab.com/timvisee/send:latest
