Accessing RDS from phpadmin Container

I Built an AWS LAB to access RDS from phpadmin container.

Here's a breakdown of my recent AWS project:

𝗩𝗣𝗖 𝗦𝗲𝘁𝘂𝗽: I configured a VPC with two Availability Zones to enhance fault tolerance. Within each zone, I created both public and private subnets, even though initially only one zone was required. This decision was made with future scalability in mind.
𝗥𝗗𝗦 𝗗𝗲𝗽𝗹𝗼𝘆𝗺𝗲𝗻𝘁:MySQL RDS instance was created and placed in the private subnet of Zone 1 to isolate the database from public internet access.
𝗘𝗖𝗦 𝗦𝗲𝗿𝘃𝗶𝗰𝗲 𝗖𝗿𝗲𝗮𝘁𝗶𝗼𝗻: Given the free tier benefits, I opted for an EC2 launch type for my ECS service and attaching with the public subnet of same AZ where the database is placed.
𝗣𝗛𝗣𝗔𝗱𝗺𝗶𝗻 𝗖𝗼𝗻𝘁𝗮𝗶𝗻𝗲𝗿 𝗧𝗮𝘀𝗸: I defined a task for a PHPAdmin container, specifying parameters such as CPU, memory, port mappings, and the Docker image. This task was then run on the ECS machines.
𝗦𝗲𝗰𝘂𝗿𝗶𝘁𝘆 𝗚𝗿𝗼𝘂𝗽 𝗖𝗼𝗻𝗳𝗶𝗴𝘂𝗿𝗮𝘁𝗶𝗼𝗻: I adjusted the VPC security group to permit traffic from the ECS to enable communication. ECS machine's security group was configured to accept incoming connections from my local machine.

𝗢𝘂𝘁𝗰𝗼𝗺𝗲: Successful implementation of the above steps allowed me to access my RDS instance's dashboard through the PHPAdmin container
