Using ObjectiveFS With Ghostunnel

NOTE: Starting in version 7.0, ObjectiveFS has built-in TLS/SSL support. stunnel is not needed anymore. For TLS details, see here.

This guide covers how to set up ghostunnel for endpoints that support only SSL. If you prefer to use stunnel, please see this stunnel setup doc

Since ObjectiveFS has built-in client side encryption and always encrypts your data at rest and in transit, you don’t need to use ghostunnel for most cases. Common uses for ghostunnel are when using an on-premise object store that supports only SSL or when using the AWS server side encryption feature.

Note: This document uses port 8086 on the localhost for the ghostunnel connection. You can replace 8086 below with the port you prefer.

Steps

1. Download and install ghostunnel from https://github.com/ghostunnel/ghostunnel/releases/

$ chmod +x ./ghostunnel

1. Verify /etc/objectivefs.env/AWS_DEFAULT_REGION points to your bucket’s endpoint

$ cat /etc/objectivefs.env/AWS_DEFAULT_REGION
us-east-2

1. Run ghostunnel on your command line (or using your init tools)

$ ./ghostunnel client \--listen=localhost:8086 \--target=<endpoint>:443
  \--disable-authentication

Example:

$ ./ghostunnel client \--listen=localhost:8086 \--target=s3.us-east-2.amazonaws.com:443 \--disable-authentication

1. To use ObjectiveFS with ghostunnel, set the http_proxy environment variable to http://127.0.0.1:8086.
   Tip: You can also create a file in the config directory /etc/objectivefs.env/http_proxy with the content as http://127.0.0.1:8086 without needing to specify it in the command line each time.
   
   Example: Running the list command using ghostunnel

$ http_proxy=http://127.0.0.1:8086 mount.objectivefs list

Example: Mount your filesystem with ghostunnel

$ http_proxy=http://127.0.0.1:8086 mount.objectivefs <bucket> <directory>

1. A single ghostunnel can have multiple parallel connections. You can also start multiple copies of ghostunnel for redundancy.
