Quick SSH Server

This Docker image provides a simple and fast way to set up an SSH server. The server allows root login with a password specified at runtime. Pre-generated SSH keys are used to ensure consistent host keys across container restarts.

Features

Based on the latest Ubuntu image.
OpenSSH server pre-installed and configured.
Root login enabled.
Root password set via an environment variable.
Consistent SSH host keys for reliable host fingerprinting.

Usage

Using the Pre-built Image

To get started quickly, you can use the pre-built Docker image available on Docker Hub:

docker pull kevinwang15/quick-ssh-server:latest
docker run -d -p 2222:22 -e PASSWORD=yourpassword kevinwang15/quick-ssh-server:latest

Build the Docker Image

If you prefer to build the Docker image yourself, run the following command in the directory containing the Dockerfile:

docker build -t quick-ssh-server .

Run the Docker Container

To run the Docker container, use the following command. Replace yourpassword with your desired root password:

docker run -d -p 2222:22 -e PASSWORD=yourpassword quick-ssh-server

Connect to the SSH Server

You can connect to the SSH server using an SSH client. Use the root user and the password you specified when running the container:

ssh root@localhost -p 2222

Environment Variables

PASSWORD: The password for the root user. This variable is required and must be set at runtime.

Example

Using the pre-built image:

docker pull kevinwang15/quick-ssh-server:latest
docker run -d -p 2222:22 -e PASSWORD=mysecurepassword kevinwang15/quick-ssh-server:latest
ssh root@localhost -p 2222

Building and running your own image:

docker build -t quick-ssh-server .
docker run -d -p 2222:22 -e PASSWORD=mysecurepassword quick-ssh-server
ssh root@localhost -p 2222
