Get your grocy server running securely in the cloud for free!

Opinionated script to deploy and run grocy (ERP beyond your fridge) on AWS secured with TLS with automated backups.

• Installs and runs grocy server version 2.7.1 and the latest version of barcode buddy on a single AWS EC2 t2.micro instance (free tier i.e. free for one year with a new AWS account).
• Enable HTTPS only access with free LetsEncrypt Certificates with auto renewal.
• Register host with DNS. Supports DuckDNS, a free DNS provider
• Backup grocy database to DropBox daily (because sh*t happens). I chose Dropbox since it is free, versions files and has easy to use tools.

• Install and run grocy on the cloud with minimal effort.
• Low cost (Preferably free)
• Automated backups
• Secure
• Make grocy upgrades painless

• Git cli
• AWS CLI installed and authenticated to an AWS account with the right permissions to create EC2 instances. Video Tutorial
• Terraform CLI installed
• Registered DuckDNS domain names for grocy and barcode buddy. DuckDNS is a free service that allows creation of a domain names for free in the duckdns.org top level domain. Use it to register domains for our servers. It will generate a token which you will need for installation.
• Dropbox account required to enable backups. It is recommended to use a separate dropbox account (i.e. not your personal account) to store the backup, since dropbox credentials are copied to the AWS EC2 instance.

Run the following commands from a command prompt.

git clone https://github.com/abhinavrau/cloud-grocy.git
cd cloud-grocy/aws
terraform init
terraform plan -out=plan

At this step, you will be prompted to enter:

• Domain name for the grocy site you want (without the duckdns.org suffix) that you registered with DuckDNS.
• Domain name for the barcode buddy site (without the duckdns.org suffix) that you registered with DuckDNS.
• DuckDNS token for your domain created in the previous step.

terraform apply "plan"

This will do the following:

1. Create a VPC, subnet, firewall rules, and a t2.micro EC2 instance running Ubuntu 18.04 with a public IP address.
2. Install Docker and docker-compose.
3. Register the Public IP address of the EC2 instance with DuckDNS for both the domain names specified earlier and wait for DNS entries to propagate.
4. Run grocy and barcode buddy as docker containers.
5. Generate free TLS certificates using LetsEncrypt with auto renewal using docker-compose-letsencrypt-nginx-proxy-companion

On completion, the script will output:

• The URL of the grocy server
• The URL of barcode buddy server
• The public IP address of the EC2 t2.micro instance running grocy and barcode buddy.
• The SSH private key for the EC2 t2.micro instance.

Your grocy server with barcode buddy on the cloud is ready! (It may a take a couple of minutes to register the LetsEncrypt certificates.)

IMPORTANT:

• Navigate to the URLs and login and change the admin password!
• Please save the SSH Key private securely in a password manager. You will need it to take backups and restoring.
• Do not delete the terraform.state files that get created.

In order to do scheduled backups to dropbox, you have to:

• Pre-configure the dropbox cli (dbxcli) prior to running the terraform apply command.
• Uncomment the "sudo ./schedule-backup.sh" line in the aws/servers.tf file before running terraform plan. Or Run the same command after installation finishes by SSH into the server.
• Backups will be taken once a day
• Backups will be stored in directory called grocy_backup on Dropbox

There is a script restore-from-backup.sh that can restore the latest backup from dropbox.

• Login to the AWS instance using SSH. From here run:

./restore-from-backup.sh

To upgrade to a new cloud-grocy release:

• SSH to the server
• Take the backup to dropbox by running:

./grocy-backup.sh

• From the base cloud-grocy directory run:

git pull

cd aws
terraform plan -out=plan
terraform apply "plan"

IMPORTANT: This will destroy the old EC2 instance and create a new one with the updated servers, so it is important to take backup.

See Restoring from Backups section mentioned previously.

If you want to completely destroy all the resources it created on AWS:

terraform destroy

This will destroy all the resources created on AWS. Please remember to backup!

I have personally tested this on my macOS. Testers on Windows and Linux needed!

To change the default behaviour, modify the variables.tf file.

Make sure you are in the aws directory and run:

terraform output host_ssh_key > ssh_key.pem
chmod 400 ssh_key.pem
ssh -i ssh_key.pem ubuntu@(terrform output grocy_host)

Or

../bin/ssh-host.sh
