Setting Up SSH Access

To set up SSH access on a customer Docker image, you need to add the following script to your templates startup script:

#!/bin/bash

# Install SSH server
apt-get update
apt-get install -y openssh-server

# Configure SSH
mkdir -p /var/run/sshd
sed -i 's/#PermitRootLogin prohibit-password/PermitRootLogin prohibit-password/' /etc/ssh/sshd_config
sed -i 's@session\s*required\s*pam_loginuid.so@session optional pam_loginuid.so@g' /etc/pam.d/sshd

# Set up SSH key
if [ ! -z "$PUBLIC_KEY" ]; then
    mkdir -p /root/.ssh
    echo "$PUBLIC_KEY" > /root/.ssh/authorized_keys
    chmod 700 /root/.ssh
    chmod 600 /root/.ssh/authorized_keys
fi

# Set SSH port
if [ ! -z "$SSH_PORT" ]; then
    sed -i "s/#Port 22/Port $SSH_PORT/" /etc/ssh/sshd_config
fi

# Start SSH service
/usr/sbin/sshd -D

​
