Setting up Dify 1.1.3 on AWS involves using docker-compose, connecting to Postgres RDS with TLS through an AWS ALB.Storing data in RDS provides benefits such as data persistence during Dify updates and security features like high availability and easy backups.Requirements include an EC2 instance, EBS storage, an EC2 instance profile, an ALB for TLS connection, and a Postgres RDS instance.Installation steps involve setting up docker-compose, installing AWS CLI v2, setting up Dify and the database, and creating the .env file.Changes need to be made to the docker-compose.yaml file to connect Dify to RDS and set up SSL requirements for the plugin daemon.A vector store like pgvector can be set up in RDS to handle vector embeddings for enhanced search capabilities within Dify.Starting up Dify with docker-compose involves running the command 'docker-compose -f docker-compose.yaml up -d'.Troubleshooting tips include checking for DB-related errors, monitoring memory and storage usage, and pruning old images and volumes.For further assistance or queries, the author welcomes comments and interaction to address any issues that may arise during the setup process.The guide provides a detailed walkthrough of setting up Dify on AWS using docker-compose and RDS with emphasis on security and data persistence.
