remie/ecs-ssh-tunnel repository overview

⁠SSH Tunnel

This SSH Tunnel provides a simplistic way to set up an SSH tunnel to a remote host to securely connect without having to expose your host too much.

⁠Usage

⁠Private key file

The container assumes your private key doesn't have a password and is mounted under /private-ssh-key.

You can also provide the private key by setting the PRIVATE_KEY environment variable with the base64 encoded string.

⁠Configuration

• $PORT the port you want to forward
• $USERNAME the username for your ssh key
• $REMOTE_HOST the remote host you want to set up a local tunnel for
• $BIND_ADDRESS the address you want to bind the tunnel to. (default: 127.0.0.1)
• $PRIVATE_KEY the private key (base64 encoded string)

⁠Running the tunnel

With private key mounted from the filesystem

$ docker run --rm -p "9200:9200" \
    -v $(pwd)/private-key:/private-ssh-key \
    -e PORT=9200 \
    -e USERNAME=elasticsearch \
    -e REMOTE_HOST=my-es-host \
    remie/ecs-ssh-tunnel

with private key provided via environment variables (base64 encoded)

$ docker run --rm -p "9200:9200" \
    -e PRIVATE_KEY=paste_your_base64_encoded_key_here \
    -e PORT=9200 \
    -e USERNAME=elasticsearch \
    -e REMOTE_HOST=my-es-host \
