I have created an ECS cluster that runs one service on Fargate with one task definition.
The task definition runs two containers that are supposed to communicate with each other:
- nginx (using
fastcgi_pass <hostname>:9000;
)
- php-fpm
I have tried running them in one task definition or in seperate services (with Service Discovery set with either A records or SRV records - I have tried all the options).
Other info:
- Public VPC with two public subnets
- Security group that allows access from itself to port 9000 (the php-fpm port)
- Load balancer connected to the nginx container on port 80
Here is one of the task definitions that I tried, in this case running the containers in the same task definition (nginx has fastcgi_pass localhost:9000;
).
I hope somebody can help me... It can't be this hard to do something so simple. Nothing seems to work.
