I have a container application running on ECS Fargate (Network awsvpc), And tried to connect MySQL database set up on EC2 instance... But it is not happening.
I can connect same database (on EC2) from local machine with same containerized application running.
Trying so hard to solve this issue, if you know please help me.
Tried other things I know:
Security group inbound as ECS service security group (also tried opening all traffic access to EC2 instance)
ECS tasks running into private subnet or public subnet (EC2 and Fargate apps, all are in same VPC)

I am using Jenkins Fargate Plugin(https://plugins.jenkins.io/amazon-ecs/) for builds and push. I have an EC2 machine and in this machine I have Jenkins master, nexus repository and sonarqube. And with this jenkins fargate plugin I create fargate containers for jenkins workers. And this workers in same subnet in EC2 machine and same vpc. But when I use whistlist on 443 port for nexus and sonarqube created fargate container cant access to nexus and sonarqube but they are on same public subnet. What should I do for the connection. I use different security groups for EC2 machine and fargate conrtainers but subnets and vpc is same.
I need to close jenkins master nexus and sonarqube login pages so ı need to use whistlist right other way can close? what should I do for comminication fargate container and EC2 machine?
Update:
Subnet is public subnet.
Security group for fargate outbound rules is all open.
The error is "Connection time out".
I have two VPC's in the same account. VPC-A(has RDS installed), VPC-B has services installed through ECS EC2 deployment.
VPC-B has multiple subnets. Services deployed through ECS EC2 service couldn't integrate with RDS. It keeps getting the following error message("Is the server running on host "....")
Where as telnet on RDS database port from Ec2instance(E1) inc VPC-B subnet can connect to the database.
But, it couldn't start the server if the same services are installed through ECS. When manually trying to start the container it works(able to connect to the database).
I also set up a Peering connection between two VPC's but the connection problem exists only when the container is started through ECS EC2 deployment.
The dropdown for public IP has "Disabled" and no other options. Subnet's are public subnets.
Any help/thoughts will be highly helpful.
As per aws docs "awsvpc" launches in a private IP and to interact with external services nat gateway needs to be attached to subnet.
https://docs.aws.amazon.com/AmazonECS/latest/developerguide/task-networking.html#task-networking-considerations
The awsvpc network mode does not provide task ENIs with public IP addresses for tasks that use the EC2 launch type. To access the internet, tasks that use the EC2 launch type should be launched in a private subnet that is configured to use a NAT gateway.
"Auto assign public IP" mode is "Enabled" with "bridge" netowrking mode on on ECS EC2 launch.
Due to organizational restrictions all EC2 instances must be spun up inside a VPC. I am running Packer from an on prem server (via a Jenkins pipe) and during the image creation, it spins up an EC2 instance inside this VPC which is assigned a private IP.
Back on my on prem server, Packer is waiting for the instance to start up by querying the private IP assigned to it and there is no connectivity between the on prem Jenkins server and the EC2 instance spun up by Packer. Therefore the process hangs is stuck at Waiting for WinRM to become available forever.
Is there a workaround to this?
I am using the builder of type amazon-ebs
A bastion host on public subnet my help you in this case. You can find the Packer configuration for bastion host here: https://www.packer.io/docs/builders/amazon-ebs.html#communicator-configuration
I have a spring boot application that is deployed to AWS Elastic Beanstalk and a Mongo database the is deployed on an EC2 instance.
I created two security groups: one for the EC2 instance and another one for Elastic Beanstalk to open the connection to each other.
However, the spring boot app still can't connect to Mongo (on the EC2 IP address).
Login to your AWS account and navigate to EC2 (Compute) dashboard.
Click the Security Group for the Ec2 instance in which MongoDB is installed
In the inbound tab, click edit
Add the private IP of the EC2 where beanstalk is running and the MongoDB port. This will allow the connectivity from your Spring boot application to MongoDB.
To test the connectivity, SSH into your EC2 where beanstalk is running and telnet the IP: port where MongoDB is running.
I have a web application launched using ElasticBeanstalk (EB) with load balancer, which instances may be added/removed based on the trigger.
Now I have a Redis server hosted on EC2 with port 6379 that I only want this very EB instances (all the instances launched by this EB) have access to that port.
EB has a security group (SG) called sg-eb and Redis has a SG called sg-redis.
All these are deployed under same VPC but may or may not be the same subnet.
How to I configure sg-redis so that all the instances under the EB have access to redis? I tried adding sg-eb to sg-redis allowing port 6379 but no luck. The only way I made it work was adding each instance's public IP to sg-redis so they have access. Though, if the load balancer adds/removes an instance, I'll need to manually configure sg-redis again.
Update #1
The Redis EC2 instance will have 2 IPs, one public and one private. You can find them when selecting the instance on the EC2 management console. Make sure you connect to that EC2 instance via this internal IP.
