Multi region environment deployments

[thomasrd1]

What is the best way to insert the .env in a multi region environment?

The deployment would run... ap-southeast-2 (dev > prod) > us-east-1 > eu-central-1

The example works great for a single region (dev>prod), but how can I automatically get the S3 Bucket name, S3 Bucket path for other regions?

Would it be easier to add some environment variables and then query them?

You can use other buckets as well, only make sure that the EC2 Role has access to read the .env from the S3 bucket.

I don't want to hard code the S3 bucket / URL to .env

I guess this can be solved by using AWS Parameter Store. You can define a parameter store and have a custom script that pulls the secrets from the parameter store into a file using the EC2 Role that the machine has to build your .env file. This seems promising and might become a great future on this project. 🤔

I remember I have opened an issue a while ago on AWS EB Roadmap repo that fixes this out-of-the-box: https://github.com/aws/elastic-beanstalk-roadmap/issues/57

Infrastructure as code is great. Except when you have to define custom codes. What you have here in this project is amazing.

I try not to hard code any bucket/keys anywhere.

There are 2 different options. Pull the config variables from AWS Secrets Manager or the Environment paramaters. Which means you need to have the elasticbeanstalk environment setup as blank before uploading the code.

I failed at searching some old issue where one of the users found that Environment Variables set in AWS Console got copied over automatically by AWS to a file somewhere in /etc or something and you could just use it as-is.

After a bit of research, I have found out about remind101/ssm-env and it seems like it's a better way to approach the issue, but still doesn't solve multi-env without some bits of hardcoding.
