SSH Setup for Deployment

Last Updated: 2026-01-31
Document Version: 1.0
Status: Active Documentation


Issue: SSH Authentication Required

The deployment script requires SSH access to the Proxmox host. You have two options:

Set up SSH key to avoid password prompts:

# Generate SSH key if you don't have one
ssh-keygen -t ed25519 -C "proxmox-deployment"

# Copy key to Proxmox host
ssh-copy-id root@192.168.11.10

# Test connection (should not prompt for password)
ssh root@192.168.11.10 "echo 'SSH key working'"

Option 2: Password Authentication

If you prefer to use password:

  1. The script will prompt for password when needed
  2. You'll need to enter it for:
    • scp (copying files)
    • ssh (running deployment)

Note: Password prompts may appear multiple times.

Quick Setup SSH Key

# One-liner to set up SSH key
ssh-keygen -t ed25519 -f ~/.ssh/id_ed25519_proxmox -N "" && \
ssh-copy-id -i ~/.ssh/id_ed25519_proxmox root@192.168.11.10

Then add to your SSH config:

cat >> ~/.ssh/config << EOF
Host ml110
    HostName 192.168.11.10
    User root
    IdentityFile ~/.ssh/id_ed25519_proxmox
EOF

Then you can use:

ssh ml110

Troubleshooting

"Permission denied (publickey,password)"

  • Check if password is correct
  • Set up SSH key (Option 1 above)
  • Verify SSH service is running on Proxmox host

"Host key verification failed"

  • Already fixed in the script
  • Script automatically handles host key changes

"Connection refused"

  • Check if SSH service is running: systemctl status ssh (on Proxmox host)
  • Verify firewall allows SSH (port 22)
  • Check network connectivity: ping 192.168.11.10

After SSH Key Setup

Once SSH key is configured, the deployment script will run without password prompts:

./scripts/deploy-to-proxmox-host.sh
