Opinionated script to deploy and run grocy (ERP beyond your fridge) on AWS, DuckDNS (free DNS provider) and LetsEncrypt

Features

• Deploys to AWS EC2 t2.micro instance (free tier i.e. free for one year with a new AWS account).
• Enable HTTPS only access with LetsEncrypt Certificates with auto renewal.
• Register host with DuckDNS
• Backup grocy database to DropBox daily (because sh*t happens). Dropbox account required to enable backups. It is recommended to use a seperate dropbox account (i.e. not your personal account) to store the backup, since dropbox credentials are copied to AWS.

Installing / Getting started

Prerequisites:

• 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 name. DuckDNS is a free service that allows create a domain for your grocy server. It will generate a token which you will need for installation.

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

At this step, you will be prompted to enter:

• Domain name 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 with a public IP address
2. Install Docker engine and docker-compose
3. Register the Public IP address of the EC2 instance with DuckDNS.
4. Run nginx and grocy as docker containers provided by the grocy-docker project
5. Generate free SSL certificates using LetsEncrypt and install it. Also does auto renewal.

On completion, the script will output:

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

Remember to Login and change the admin password!

Backups

• In order to do scheduled backups to dropbox, you have to pre-configure the dropbox cli (dbxcli) prior to running the terraform apply command. You also need to uncomment the "sudo ./schedule-backup.sh" line in the aws/servers.tf file before running terraform plan.
• Backups will be taken once a day
• Backups will be stored in directory called grocy_backup on Dropbox

Restoring from Backups

• There is a script restore-from-backup.sh that can restore the latest backup from dropbox. This has not been tested much, so use with care!

Deleting the Install

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

terraform destroy

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

Testing

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

Developing

TODO

Configuration

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

SSH access

In order to access the AWS instance:

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