How to import Resource ID into UserData in Cloudformation

Asked 2021-May-14 at 22:12

I have a cloudformation template with an efs filesystem and an instance launch configuration. I need to reference the efs filesystem id in the UserData script, as I want to mount the efs on launch. I've tried it with echo ${!Ref EFSFileSystem} like this:

...

ANSWER

Answered 2021-May-14 at 22:12

You have a !Sub on the string already, so instead of ${!Ref EFSFileSystem} you just need to do ${EFSFileSystem}. That will be replaced with the default output of the resource, in this case, the Id.

Important point to note to get the syntax right is to use Json with Yaml when using multiple Intrinsic functions. Updated syntax below. For Environment value DEV, this creates a bucket of name content-input-dev

CloudFormation - Install and configure CloudWatch Agent to EC2 Instances

Asked 2020-Jun-24 at 04:58

I have a CloudFormation template that create ec2 instances using LaunchTemplate, but I want to add cloudwatch agent to the instances, but I can't figure what's wrong.

I have 2 configSets, but the cfn-init get stuck in "02_download_app" > "Command run_app", this part I run a jar file from /.

Here is the output from /var/log/cfn-init-cmd.log, I noticed that after the command run_app the jar get stucked 17:25, and some time later 17:42 I connect to the instance kill the jar and relaunch and it continues the script successfully, I think the error is some encoding problem, but I don't know where: in the jar? in log4j config file?, etc.

Answered 2020-Jun-24 at 01:38

I guess you are referring this sudo java -jar /tmp/app.jar &? I think you should kill it in your Init after your test finishes.

One way to do this could be as follows:

QUESTION

AWS CloudFormation Macros are not invoked while deleting Stacks. They are invoked only while creating/updating Stacks

Asked 2020-Jan-19 at 17:11

I have cloned this repo and deployed the Count stack successfully.

...

ANSWER

Answered 2020-Jan-19 at 17:11

Because Count is a macro, not a custom resource. A macro is a preprocessor for the Cloudformation template. It takes the template, changes it and outputs a new template. Cloudformation then carries on creating the stack using the updated template.

When you delete the stack, it deletes all resources defined in the stack so there is no need to call the macro again.

In contrast a custom resource is executed at deployment and is used to control resources that Cloudformation doesn't support or to implement other custom logic. The custom resource will be invoked when the stack is deleted to give it a chance to clear up the resources it created.

QUESTION

Access DynamoDB in Golang Fargate Task

Asked 2019-Oct-02 at 11:05

I'm trying to access DynamoDB from my Fargate task, which is written in golang. And all I get is a timeout. What I am missing?

I'm using the Cloudformation templates from AWS Labs (here) plus a task role that allows full DynamoDB access. It's the simplest public subnet template plus the Fargate one.

I tried adding a VPC endpoint, but it made no difference.

Running the task on my machine works. Running a Python (Flask) task that does (more or less) the same works both locally and on AWS. It's the same setup, I just changed the task image.

This is the code:

...

ANSWER

Answered 2019-Oct-01 at 23:15

Timeout is often a network Issue. Have you checked security groups used by both the ECS task and Dynamo DB. Need to make sure you have rules setup to egress out of ECS and ingress into DynamoDB on the correct ports.

You said you setup an endpoint for Dynamo in the VPC. Not clear from your OP if you are trying to connect to private endpoint in a private VPC or if you are trying to go through the public internet. If you are trying to go through public internet you need to also check that your ECS task is in a VPC that has a NAT gateway out to the public internet. It looks like you are trying to connect through 127.0.0.1 or an ELB DNS to connect to the DynamoDB service which doesn't make sense to me.

Create S3 only user

Asked 2019-May-05 at 10:47

I am trying to create a S3 only user who will by definition have no access to any other resource. The user can upload and download files from S3. I have created a basic template that can be found here...

https://github.com/shantanuo/aws-cloudformation-templates/blob/master/aws/services/IAM/IAM_Users_Groups_and_Policies.yaml

But it is allowing access to cloudformation that is not necessary in my case. I have read the following pages, but do not know how to include them in my template.

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-iam-user.html

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-iam-role.html

https://docs.aws.amazon.com/AWSCloudForation/latest/UserGuide/aws-properties-iam-group.html

What are the minimum parameters required to create a S3 only user?

Is Elastic IP obligatiory for a NAT instance?

Asked 2019-Mar-30 at 10:28

Is an Elastic IP obligatory for a NAT instance? Or can I just continue with a public IP?

The CloudFormation template samples (like the one here) feature an elastic IP address but I am not a fan of assigning one if not really a must.

No, Elastic IP is not obligatory for NAT instance. You can continue with the Public IP address. Elastic IP requires when you go with the NAT Gateway.

UserData script with Resource Attribute CloudFormation

Asked 2018-Feb-05 at 16:43

The main question: How to I reference dependent resource attributes in a cloud formation template to build out a user data script.

What I have tried:

Approach listed here.
Examples from sub function

I am building a CloudFormation template for a three node Kafka cluster.

The approach I am taking here is configuring Zookeeper and Kafka on each node of the cluster using a UserData script on the EC2 instance.

I am using the Sub and Base64 functions to populate my user data script with the PrimaryPrivateIpAddress of my NetworkInterface but they are coming across as empty strings instead of the actual values. I know that the values are being populated correctly because they are part of my output in the template.

I have included the resource block of my template below as a reference. I omitted some uninteresting parts for the sake of succinctness. I also am illustrating a couple different approaches that I have tried to the EC2 resource blocks are not consistent.

Answered 2018-Feb-05 at 16:43

I think you're on the right path. I would just modify a bit the way you pass the 3 "private" substitute variables, for something like this (which I use quite often in my templates):
