About Hetzner Cloud

Website: https://hetzner.com*

Hetzner Cloud is an affordable cloud hosting provider with datacenters in the Europe, and East and West US.

It provides server nodes, firewalls, load balancers, generous traffic (20TB per node) and other features that are perfect for development and some production workloads.

Hetzner is much cheaper for the equivalent CPU and memory you get on other providers like DigitalOcean, AWS, etc.

However, Hetzner does not (as of December 2022) have managed databases, managed Kubernetes services and other services like many of the cloud providers have. So chose your cloud provider(s) based on your needs.

Here is a pricing example comparing a 2vCPU and 2GB AMD/Intel Node running Linux on Hetzner, DigitalOcean, AWS, Azure and GCP.

• Hetzner: cpx11 - ~$4/month
• DigitalOcean: s-2vcpu-2gb - $18/month
• AWS: t3a.small - ~$14/month (not including traffic or storage)
• Azure: Azure doesn't have a 2vCPU/2GB option, but their B1ms node with 1vCPU/2GB is ~$15/month not including traffic and persistent storage.
• GCP: e2-standard-2 - ~$14/month (not including traffic and storage)

Hetzner Cloud Account Setup

1. Visit hetzner.com* and sign up.
2. Enable Multi Factor Authentication (2FA) on your account. I recommend using Authy to store MFA as it allows for multiple devices and backups.

• Click the "person" icon in the top right and select "User Account"
• Under "Settings" on the left menu, click "Two-factor authentication".
• Click "Add new authentication method" and select "Mobile Device".
• Scan the QR code with your mobile device using Authy (or similar app) and fill in "Description", your "Account Password" and the One Time Password (OTP) shown in the Authy app after you scanned the QR code.
• Click "+Add" and now your account is protected with multi-factor authentication

Managing Hetzner Cloud resources with the hcloud cli

1. Install the Hetzner CLI: https://github.com/hetznercloud/cli
2. Add your account using the API key you generated earlier by typing hcloud context create some-nickname, replacing some-nickname with what you want to call the account. You will be prompted for your API key.
3. Run some of the following commands to begin using the hcloud cli

Here are some basic commands you can use to configure resources in Hetzner Cloud using the Hetzner CLI. If you need to know how to use the hcloud commands, you can just add --help to any command to see the options.

• hcloud --help
• hcloud image list
• hcloud image list --type system
• hcloud server
• hcloud server list
• hcloud ssh-key list
• ssh-keygen -t rsa -b 4096 -f ~/.ssh/hetzner-test-key
• hcloud ssh-key create --name hetzner-test-key --public-key-from-file ~/.ssh/hetzner-test-key.pub
• hcloud server create --location ash --type cpx21 --image - ubuntu-20.04 --ssh-key hetzner-test-key --name $SOMENAME
• hcloud server create-image --type snapshot $INSTANCEID
• hcloud server delete $INSTANCEID
