Hi all, we got EKS that holds our web app When we try to upload a evan a small, 250 KB file it is throwing 413 error response that is for file size limit exceed. The php.ini file seems to be ok. • post_max_size = 12M • upload_max_filesize = 10M • memory_limit = 128M Any ideas what else we should check?

Check client_max_body_size in your nginx config.

Hi Everyone- question about RDS/postgres and schema permissions. We have an RDS instance that was set up with a bastion host that forwards traffic from port 8887 to 5432 on the RDS instance. I’ve been accessing the instance with SSH tunneling and have successfully created and populated tables. I wanted to POC a data viz program and changed the instance to publicly accessible but only open to traffic on port 5432 for a couple of IP addresses. I can successfully connect to the instance now, but all the schemas I created while using SSH tunneling disappear. I’ve checked out permissions for the user but nothing stands out.

Is there a setting somewhere in RDS/postgres that connects port to schema privileges?

did you use the same db user?

Alex Jurkiewicz avatar
Alex Jurkiewicz

are you looking in the same database? Different programs can offer a different default

Sarah Donehower avatar
Sarah Donehower

I connected to the same database as the same user. The only thing I changed was the port.

Hello everyone! I’m looking at [this> module to create a website and host it in AWS S3. I see that it stores all the traffic (and what not) logs also in another S3 bucket. I wonder how do people usually go about analyzing (mostly reviewing) them :thinking_face:. Is it possible to store/send them to CloudWatch also/instead? So far, I can only download them to see what’s going on, but I’m sure that’s far from the trend </i](https://github.com/cloudposse/terraform-aws-s3-website/)

Analyzing Amazon S3 server access logs using Amazon ES | Amazon Web Services attachment image

September 8, 2021: Amazon Elasticsearch Service has been renamed to Amazon OpenSearch Service. See details. When you use Amazon Simple Storage Service (Amazon S3) to store corporate data and host websites, you need additional logging to monitor access to your data and the performance of your application. An effective logging solution enhances security and improves […]

Constantine Kurianoff avatar
Constantine Kurianoff

You don’t have to actually use ElasticSearch and Kibana, but it is just so you can get an idea of how people analyze S3 access logs

x80486

Thanks @! I’ll check that out! I’m used to see all the logs in CloudWatch, so I was wondering that this could be the same, but probably the trend is to just use Elasticsearch to ingest them into that engine for further use.

Constantine Kurianoff avatar
Constantine Kurianoff

Yes, if you look for rich data visualization, you go with either ElasticSearch, or Grafana, or anything of that kind. I don’t have much experience with CloudWatch, but I think you can build dashboards and some good visualizations there as well

Hi everyone, I seen big swings in the creation times of RDS MYSQL being created from a snapshot. Sometimes it’s 30min, other times more than 2h in which case terraform times out. Any of you had similar experience?

Darren Cunningham avatar
Darren Cunningham

yup - depends on the size of the snapshot, the size of the instance you’re restoring and the queue/availability in that AZ…which TMK is a black hole

Hey everyone, so I have a simple question that I’m probably searching poorly for an answer for, but can’t find. So even just posting a link to an article about it is enough for me .

How do you request an internal ELB from say a node application?

For reference what I’m trying to do: My company has always worked in a monolith architecture, which is becoming a huge pain for us, so we want to split off some stuff into micro services. I’m trying to start with the most basic setup possible that allows us to easily add on to/move to better architecture in the future. We run a grails (Groovy/Java based back end) on elastic beanstalk instances. I want to launch the first service in a few EC2 instances (1 per environment) to start.

What I’m trying to figure out right now is the routing to keep the request from having to go out to the internet and back in to the ELB we are currently using. I know I can use a new ELB that’s internal to route requests dynamically based on URI so that we don’t have to hard code IPs/change per environment. Is there a specific internal IP/url the load balancer is always launched to? Or how can I consistently request it from a grails/node application. Am I overthinking it?

Alex Jurkiewicz avatar
Alex Jurkiewicz

Unless you are going to be sending terabytes of data, don’t worry about “routing to keep the request from having to go out to the internet”

beaur97 avatar
beaur97

@ it’s more so that this is an auth service that has zero need to even be exposed to the public

Alex Jurkiewicz avatar
Alex Jurkiewicz

Each ALB (you said ELB but I assume you aren’t using that old school thing) has a hostname, this hostname is fixed for the life of the LB.

You can CNAME a prettier name to that. For example [my-service.company.com> CNAMEs to <http://alb-1234567890abcdef.amazonaws.com|alb-1234567890abcdef.amazonaws.com](http://my-service.company.com).

Then, add a security group to the load balancer which states “only allow incoming requests on tcp/443 from security group app-servers”

Alex Jurkiewicz avatar
Alex Jurkiewicz

The security group will provide protection against public exposure. And you can also deploy the ALB into a private subnet, so it has no routable public address people can connect to.

Ah, that’s a great explanation. Thank you!

Good morning. I am not able to get AWS codepipeline to work with the “cloudposse/ecs-codepipeline/aws” module. I get an error:

Error: POST <https://api.github.com/repos/><name><app>/hooks: 404 Not Found []

Here is the main.tf for the pipeline:

  privileged_mode             = true
  cache_bucket_suffix_enabled = false # important: see <https://github.com/cloudposse/terraform-aws-codebuild/issues/91>
}

we have to use the deprecated but still supported aws oauth access instead of codestar connect is not an option as we are multi-region and it is not supported in ap or eu. Any help greatly appreciated.

How can I test connectivity for created kafka service? It seems apps cannot use it Here is the config I used to create AWS MSK

module "kafka" {
  source = "../../external_modules/cloudposse/terraform-aws-msk-apache-kafka-cluster"
  # version = "0.6.3"
  namespace = "testnamesapce"
  stage     = "dev"
  name      = "msk"
  vpc_id    = module.vpc.vpc_id
  security_groups        = ["sg-XXXXXXXXXXXX", "sg-XXXXXXXXXXXX"]         
  subnet_ids             = ["subnet-XXXXXXXXXXXX", "subnet-XXXXXXXXXXXX"]
  kafka_version          = "2.8.0"
  number_of_broker_nodes = 2 # this has to be a multiple of the # of subnet_ids
  broker_instance_type   = "kafka.t3.small"
  broker_volume_size     = "100"
}

When I use netcat from EKS pods, I can reach Zookeeper nodes Error log from apps

yep, checking everything, just wondering what might be the root cause as in overall it looks fine

Darren Cunningham avatar

typically for me when I’ve seen unexpected timeouts it’s either networking (usually security groups) or IAM…usually with the latter though it’s not perms but rather an expired session

the problem was that by default TLS in transit was used which didn’t allowed to troubleshoot and etc… changed TLS -> TLS_PLAINTEXT and issue solved (we don’t use certificates so far)

RDS Event Subscriptions: I’m trying to send RDS event subscriptions to an SNS topic, then have a lambda send those as a webhook to MS Teams. but following the AWS blog post about SNS to teams webhooks, the message I see in my teams channel is:

 {"Event Source":"db-snapshot","Event Time":"2021-10-01 02:09:04.371","Identifier Link":"<https://console.aws.amazon.com/rds/home?region=us-west-2#snapshot:id=rds:dev-mpa-spa-db-01-2021-10-01-02-09>","Source ID":"rds:dev-mpa-spa-db-01-2021-10-01-02-09","Source ARN":"arn:aws:rds:us-west-2:730458288754:snapshot:rds:dev-mpa-spa-db-01-2021-10-01-02-09","Event ID":"<http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_Events.html#RDS-EVENT-0090>","Event Message":"Creating automated snapshot"}

.. I want to customize this to something more readable. The python code in the lambda looks like below, and it’s basically blindly sending out the contents of the Message object. Anybody customized their events notifications before?

    url = "<https://outlook.office.com/webhook/xxxxxxx>"    
    msg = {

    encoded_msg = json.dumps(msg).encode('utf-8')
    resp = http.request('POST',url, body=encoded_msg)

        "message": event['Records'][0]['Sns']['Message'], 
        "status_code": resp.status, 
        "response": resp.data
