If you’re running a Fargate task and it’s not able to read secrets from AWS Secret Manager, there are a few things you can check:
Verify that the Fargate task has the correct IAM permissions to access the secret. You need to grant the task the secretsmanager:GetSecretValue permission for the specific secret that it needs to access. You can do this by adding the necessary permission to the task execution role, or by creating a separate IAM role and attaching it to the task.
Check that the secret name and ARN are correct. You can confirm this by checking the secret name and ARN in the AWS Secret Manager console or by using the AWS CLI.
Make sure that the secret is in the same region as the Fargate task. Secrets are regional resources and can only be accessed from within the same region.
Check the VPC configuration of your Fargate task. If your task is running in a VPC with a private subnet, you may need to configure VPC endpoints for Secrets Manager to allow the task to access the service.
Check the network configuration of your Fargate task. If your task is running in a private subnet and needs to access the internet to reach the Secrets Manager service, you may need to configure NAT gateways or proxies.
Verify that the environment variables or container definitions in your task definition are set up correctly. Ensure that the secret is referenced using the correct syntax, such as
${secretsmanager:my-secret:secret-string:password}.
If none of these steps help to resolve the issue, you may need to enable additional logging and debugging to identify the root cause of the problem.
