Vercel For Frontend requires several environment variables to connect to AWS S3 for storage. These variables must be set before starting the services.
Required Variables
The platform requires the following environment variables to function:
AWS Configuration
Your AWS IAM access key ID with S3 permissionsUsed in:
upload-service/src/utils/uploadFiles.ts:5deploy-service/src/utils/donwloadS3Folde.ts:6
Your AWS IAM secret access key corresponding to the access key IDUsed in:
upload-service/src/utils/uploadFiles.ts:6deploy-service/src/utils/donwloadS3Folde.ts:7
The AWS region where your S3 bucket is located (e.g., us-east-1, us-west-2)Used in:
upload-service/src/utils/uploadFiles.ts:7deploy-service/src/utils/donwloadS3Folde.ts:8
S3 Bucket Configuration
The platform uses a hardcoded S3 bucket name: vercel-frontend
This bucket name is referenced in:
upload-service/src/utils/uploadFiles.ts:20deploy-service/src/utils/donwloadS3Folde.ts:16deploy-service/src/utils/donwloadS3Folde.ts:44deploy-service/src/utils/donwloadS3Folde.ts:76
Make sure your S3 bucket is named vercel-frontend or update the bucket name in the source code to match your bucket.
Setting Environment Variables
Development (.env)
Production (Linux/macOS)
Production (Windows)
Docker
Create a .env file in the root of each service directory:# .env file
AWS_ACCESS_KEY_ID=AKIAIOSFODNN7EXAMPLE
AWS_SECRET_ACCESS_KEY=wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY
AWS_REGION=us-east-1
Both upload-service and deploy-service need their own .env files with these variables.
Export environment variables in your shell:export AWS_ACCESS_KEY_ID="AKIAIOSFODNN7EXAMPLE"
export AWS_SECRET_ACCESS_KEY="wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY"
export AWS_REGION="us-east-1"
~/.bashrc or ~/.zshrc for persistence. Set environment variables using Command Prompt:setx AWS_ACCESS_KEY_ID "AKIAIOSFODNN7EXAMPLE"
setx AWS_SECRET_ACCESS_KEY "wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY"
setx AWS_REGION "us-east-1"
[System.Environment]::SetEnvironmentVariable('AWS_ACCESS_KEY_ID', 'AKIAIOSFODNN7EXAMPLE', 'User')
[System.Environment]::SetEnvironmentVariable('AWS_SECRET_ACCESS_KEY', 'wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY', 'User')
[System.Environment]::SetEnvironmentVariable('AWS_REGION', 'us-east-1', 'User')
Pass environment variables when running containers:docker run -e AWS_ACCESS_KEY_ID="AKIAIOSFODNN7EXAMPLE" \
-e AWS_SECRET_ACCESS_KEY="wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY" \
-e AWS_REGION="us-east-1" \
your-image
.env file with Docker Compose:services:
upload-service:
env_file:
- .env
Verifying Configuration
After setting environment variables, verify they’re accessible:
echo $AWS_ACCESS_KEY_ID
echo $AWS_REGION
Never commit .env files or expose your AWS credentials in version control. Add .env to your .gitignore file.
