Hi guys, I’m having trouble accessing the kibana web interface via a browser after running the terraform module.

I’m connect to a VPN and allowed the VPN cidr block to access the es cluster yet when I hit the kibana link, I get {"Message":"User: anonymous is not authorized to perform: es:ESHttpGet"}.

I tried adding the cidr block to the access policy but I get UpdateElasticsearchDomainConfig: {"message":"You can’t attach an IP-based policy to a domain that has a VPC endpoint. Instead, use a security group to control IP-based access."}

I can use the domain template to not require signing request with iam credential, which does allow me to access kibana but this is not my ideal way to set it up.

Looks like I’m having some issue with the EKS module https://registry.terraform.io/modules/terraform-aws-modules/eks/aws/4.0.2

is there no way to get VPC IPs now?

hm, maybe its just the subnet tagging that I was missing

Tutorial: Creating a VPC with Public and Private Subnets for Your Amazon EKS Cluster - Amazon EKS

This tutorial guides you through creating a VPC with two public subnets and two private subnets, which are provided with internet access through a NAT gateway. You can use this VPC for your Amazon EKS cluster. We recommend a network architecture that uses private subnets for your worker nodes, and public subnets for Kubernetes to create public load balancers within.

@cabrinha the latest version of the dynamic subnet module handles the public private subnet tagging correctly.

cabrinha avatar
cabrinha

nice thanks

cabrinha avatar
cabrinha

are there tags needed?

cabrinha avatar
cabrinha

never saw any docs on that

jamie avatar
jamie

It depends. Many of the kubernetes services that need to access and discover aws resources require that those resources are tagged in a way that relates to the kubernetes cluster

jamie avatar
jamie
Such as [Spinnaker.io> and <http://cpco.io cpco.io](http://Spinnaker.io)

The dynamic subnets module allows you to specify a tag and a value

@cabrinha regarding what @jamie said, there are two variables https://github.com/cloudposse/terraform-aws-dynamic-subnets/blob/master/variables.tf#L1 and https://github.com/cloudposse/terraform-aws-dynamic-subnets/blob/master/variables.tf#L7 which you can use to implement any type of tagging for the subnets

yeah thats expected when you’re making on ECS cluster, VPC and all that

I have a few things still to do today:

  • Complete the codepipeline build and deploy to ecr from s3 source
  • Complete the task wrapper
  • Complete the IAM roles required for running the tasks
  • Complete the ECS Service Update pipeline

hello

let me know if you need any help on the app mesh module, it looks great so far

jamie avatar

@cabrinha when did you need it by? I am starting by making an mvp using terraform 0.12, and I’m not going to include all of the node features like logging and health checks at the start

cabrinha avatar
cabrinha

i’d like to use terraform 0.11

cabrinha avatar
cabrinha

and need? well the sooner the better

jamie avatar
jamie

So once the mvp is done, you can do pr’s to add in other features and such

cabrinha avatar
cabrinha

nope, we use our own in-house module

jamie avatar
jamie

Ok. So to make app mesh work the task definitions have to have an extra two sidecar containers running in them

cabrinha avatar
cabrinha

sure, envoy and xray

jamie avatar
jamie

Yeah.

cabrinha avatar
cabrinha

thats easy, i’ve got my task-definition sorted out already

jamie avatar
jamie

So what I’ll do it create a template wrapper for generating the task def

jamie avatar
jamie

That adds the sidecars as well

jamie avatar
jamie

So you can pass in your container def, and ports, and app mesh name, and it outputs the full task def

jamie avatar
jamie

With the ports, proxy, and labels in place

cabrinha avatar
cabrinha

hm ok that sounds cool

jamie avatar
jamie

I’ll need to make it for when I do the example anyway

jamie avatar

Anyway, I’ll update it further tomorrow

Hey guys, using this module: https://github.com/cloudposse/terraform-aws-s3-log-storage?ref=master and running into an issue where the ALBs I’m creating don’t have access to the bucket. Is that an attribute input I need to set?

This module creates an S3 bucket suitable for receiving logs from other AWS services such as S3, CloudFront, and CloudTrail - cloudposse/terraform-aws-s3-log-storage

Woah! just hit my first v0.12 compatibility gotcha. We have extensive use of the null-label module and are running v.11. So this hit us… https://github.com/cloudposse/terraform-null-label/commit/e2b880b2bad3cd8ceaa87c56176c15d92e28775d Anyway - a quick sed -i "s/.../.../" solved it.

(it’s not possible to maintain backwards compatibility between releases and pinning to a release is the only way to ensure stability in a global ecosystem of terraform modules)

yup - I guess I would need to thank our consultant for that. Luckily it’s not pinned to master everywhere - just this one project and a simple enough PR to fix.

ian avatar

really really stupid question but I’m so lost: i’m trying to provision a cross-region rds replica but I can’t figure out how to create KMS keys for two different regions (us-east-2 for the source db and us-west-2 for the replica db). Do I resource two aws_kms_key and specify the region somehow?

no a senior dev has rolled his own setup but it’s similar to those modules and I can use them as a reference

Hey all, does anyone have some recommendations on a terraform module setup for an ecs fargate cluster setup? It needs to support 4 services per cluster, alb, possible nginx side car container integration. Thoughts? I had one working for a while, but the tags broke.

Steven avatar
Steven

I’m in the process of upgrading mine for fargate support. Need to finish it this week. Have too many things that need it

Mike Nock avatar
Mike Nock

There was an awesome module by azavea but the tags broke on it for TFE, so I gotta find a new module. The last one was perfect, created the ALB, the ECS cluster, multiple services.

Mike Nock avatar
Mike Nock

autoscaling policies, etc. Preferably I could find another one like it, but if I have to use multiple, oh well. What are you using in your setup?

Steven avatar
Steven

Mine handles ECS service on ECS2, alb, , tags, and things. It is for a service. So, you can create as many services as needed. Both container and task definitions can be overridden for more complex setups (like sidecars, proxies). Partial fargate support is there. But not awsvpc networking yet
