Backend task definition

Note: As mentioned earlier, you can use images from either ECR or Dockerhub in this section.

Configuring Task Definition for Backend Service

Still within the ECS Console interface:

• Select Task definitions
• Click Create new task definition.

Enter the following information for the task definition:

• Family name: enter fcjresbar-task-be
• In the Infrastructure requirements section:
  • Launch type: choose AWS Fargate
  • OS, Architecture, Network: choose Linux/x86_64, and the default network will be awsvcp when AWS Fargate is selected.

Next information:

• CPU: 4 vCPU
• Memory: 8 GB
• Task role and Task execution role as default.

In the container definition section, fill in the following details:

• Name: backend
• Image URI: the URI of the backend image from either ECR or Dockerhub; here, we will use ECR.
• Container port: 5000; protocol: TCP; App protocol: HTTP
• Resource allocation limits:
  • CPU: 2
  • Memory hard limit: 4
  • Memory soft limit: 3

Next, add environment variables, which are important. Without this configuration, the NodeJS server inside won’t run. These include:

• MYSQL_USER = admin
• MYSQL_PASSWORD = letmein12345
• MYSQL_DATABASE = fcjresbar
• DB_HOST = “your rds endpoint”
• DB_DIALECT = mysql
• PORT = 5000
• JWT_SECRET = 0bac010eca699c25c8f62ba86e319c2305beb94641b859c32518cb854addb5f4

Keep the default configurations.

Finally, click Create to create the task definition.
