AWS Cloudformation Stack - End to End deployment

• 1x EC2 Server (Dockerised Mastodon Instance)
• 1x RDS PostgreSQL (for Database)
• 1 x ElasticCache Redis (for shared cache)
• 1 x S3 Bucket for storage (with IAM user account linked)

Installation Guide

1. Setup a new Route53 zone and forward the domain nameservers correctly.
2. Register with mailgun.com and setup required DNS records for approval.
3. Create the AWS CFN Stack with the required details.
4. Register an account on your instance (log in and promote as admin using cli)

Troubleshooting

User-data/meta-data debug information is stored in /var/tmp/bootstrap.txt - /var/tmp$ tail -f /var/tmp/bootstrap.txt

TODO

• Setup scheduled tasks (documentation related to recommend tasks is slim)
• Automate creation of admin account (task is currently interactive only)
• 1 x ElasticSearch [Optional] (for full text search)
• KMS for at-rest encryption
• EIP for dedicated Public IP.

Cost

• EC2 Instance: $16.79 (t2.small)

• S3 Bucket: $5-$100

• ElasticCache: $13.14 (cache.t2.micro)

• RDS PostgreSQL: $13.14 (db.t2.micro)

• Monthly cost estimated at: $50~ a month

• I'm running my https://aus.social instance on t2.small instances and we're almost at 100 active users.
• While much more expensive than digital ocean but much more stable with lower techdebt due to the managed services (RDS/ElasticCache).
