SSH Container Hosting

This guide explains how to set up an SSH container that can create a secure reverse SSH tunnel from your local server to a publicly accessible server. This setup is particularly useful when you need to access resources on a local server via a server that is open to the internet.

By sharing resources over the SSH tunnel, your data will be encrypted (using HTTPS), and the IP address of your local server will remain hidden.

Step 1 - Domain

Get a domain, for example from namecheap.com. Choose your domain, e.g., yourdomain.xyz. Next, set up an A Record with the Host as @ (or a specific prefix you want to use, e.g., www) and the Value as your IP address.

Step 2 - Install

Install the packages needed

sudo apt install docker.io npm git nano
npm install --global yarn

And pull the GitHub repository

git pull [email protected]:fridolinvii/ssh-container-https.git

and enter the folder.

cd ssh-container-https

Step 3 - Setup

This gives the parameters to build the dockers. Copy the .env.template to .env, and edit them accodingly to your wishes. Copy:

cp .env.template .env

Edit:

nano .env

Step 4 - SSH-Key

Create a SSH key on your local server:

ssh-keygen -t ed25519

Copy the public key into the file authorized_keys

Step 5 - Start

I followed the instruction of nginx-proxy/acme and summarized it for my needs. Execute

./build.sh

and follow the instruction. This will build you three dockers. After a few moments you can use it for e.g., a Reverse SSH

A reverse SSH tunnel from your local server to the publicly accesible server can be created by entering the command similar to:

ssh -i PATH_PRIVATE_KEY -tt -R PORT_LOCAL:0.0.0.0:PORT_GLOBAL user@DOCKER_SITE_ADDRESS -p PORT_SSH
