Fargate Environment Variables about amazon-ecs-developer-guide

[vzaharee]

Three years later and this is still a problem. In case it's useful to anyone, below is the list of environment variables set by Fargate at the time of this comment. (Up to you to decide if you want to rely on them though as they're not [all] documented!)

var	comment
AWS_CONTAINER_CREDENTIALS_RELATIVE_URI	mentioned here: https://docs.aws.amazon.com/AmazonECS/latest/developerguide/task-iam-roles.html#task-iam-role-considerations
AWS_DEFAULT_REGION
AWS_EXECUTION_ENV	Stack Overflow says the values are AWS_ECS_EC2 for EC2 launch type and AWS_ECS_FARGATE for Fargate. I can confirm the latter.
AWS_REGION
ECS_CONTAINER_METADATA_URI	mentioned here: https://docs.aws.amazon.com/AmazonECS/latest/developerguide/task-metadata-endpoint-v3.html
ECS_CONTAINER_METADATA_URI_V4	mentioned here: https://docs.aws.amazon.com/AmazonECS/latest/developerguide/task-metadata-endpoint-v4.html
