Question: How do you bootstrap IAM/service/machine roles for CICD and allow the repository to self manage? example: A repository of terraform files deployed with github actions, with n number of environments. A single IAM role is assumed by the action, how can I bootstrap this role and allow it to be updated by a workflow in the same repo? ( I asked this question in #terraform and received great responses, just for discussion )

@Erik Osterman (Cloud Posse) qq - in the above session you mentioned you folks have a way to create schema for mysql.

Could you please share if you are using https://github.com/hashicorp/terraform-provider-mysql ?

If so, how do you deal when with the situation when your DB instance is in a private subnet (which it should be in a prod env)?

Sadly the above provider doesn’t work with ssh tunnel/ socks etc. Also the fact that credentials must be provided ….

Erik Osterman (Cloud Posse) avatar
Erik Osterman (Cloud Posse)

The only way to handle this is either using a VPN or with GitOps and private runners (we use the latter)

DaniC avatar

fair, that is what i have today with GHA self-hosted runners running as docker containers inside EC2 (acc A) and have Peering with all the other acc where i need to connect.

Question: are there any SQL database (postgres compat) solutions which run in AWS (EC2 or EKS), and outperform AWS Aurora in terms of write speeds, replication speeds, and overall performance?

Max Lobur (Cloud Posse) avatar
Max Lobur (Cloud Posse)

pricing is not on the radar

Max Lobur (Cloud Posse) avatar

• Also any experience from anyone who migrated either side?

Max Lobur (Cloud Posse) avatar
Max Lobur (Cloud Posse)

candidates: CockroachDB, Percona

Max Lobur (Cloud Posse) avatar
Max Lobur (Cloud Posse)

• Also does anything 3rd party implement query priority in postgres?

jose.amengual avatar
jose.amengual

it will be hard to bit the I/O performance of the aurora storage solution

jose.amengual avatar
jose.amengual

which at the end of the day is what 70% of the performance of any database?

1
jose.amengual avatar
jose.amengual

I have hear of people using proxies that do some other stuff on front of aurora

Max Lobur (Cloud Posse) avatar

@ can you elaborate a bit? do you mean to/from Aurora?

Max Lobur (Cloud Posse) avatar
Max Lobur (Cloud Posse)

From 3rd party to Aurora or vise versa. What were the benefints, losses, pain points

1
jose.amengual avatar
jose.amengual

the version changes is a paint if someone is using specific version features

jose.amengual avatar
jose.amengual

getting the sizing right is another peoblem

jose.amengual avatar
jose.amengual

Migration of data is another problem, you can’t just copy on the aurora drive since is not available for you

jose.amengual avatar
jose.amengual

and s3 import only works for mysql so then pgdump needs to be used for postgres

Question: On moving away from Terragrunt, and completely into native Terraform, what are good resources to learn about how to split Terraform workspaces for infrastructure? We are using a centralized infrastructure-live repository but would like to reduce both the blast radius and time to plan/apply (e.g. separate repositories for tf-networking, tf-messaging…).

Also, how to organize infra repositories taking multi-region/multi-account into consideration(replied in thread)

Curious how many dev teams are using conventional commits at all –> https://www.conventionalcommits.org/en/v1.0.0/

Conventional Commits

A specification for adding human and machine readable meaning to commit messages

A couple of teams I’ve been on have tried, but it ended up being a burden and a point of friction. In theory it’s great for autogenerating the changelog but it’s annoying to enforce

There are various ways to enforce the format, so that’s not much of an issue. My issue is the added burden on developers who are forced into making sure they write commit messages in specific ways

How do you suggest doing DB Snapshot Dump and Restore from Production to Dev/Staging/QA envs ?

Sherif Abdel-Naby avatar
Sherif Abdel-Naby

Yea way we do it for preview environments that we dump DB from prod to staging, do the tokenization, and then take a EBS Snapshots from this. The we create volumes from it on each preview environment deployment and create its PV and PVCs.

Sherif Abdel-Naby avatar
Sherif Abdel-Naby

It’s quick, take about 2~3 mins to restore, and dump is done daily at night.

Sherif Abdel-Naby avatar
Sherif Abdel-Naby

Was just asking if there is other ways of doing that

Max Lobur (Cloud Posse) avatar
Max Lobur (Cloud Posse)

Nope, it sounds correct The only thing that I would change here is doing the tokenization in prod to decrease threat radius.

My Q&A Questions

  1. Suppose you have a K8S cluster per team, would you do a VPC per cluster ? Or VPC per stage (Prod/staging/testing) ?

  2. How to pass information between Terraform and the Helm Chart (deployed via Argo) ? a. For Testing/QA we have DB Snapshot Volumes that we will use Terraform to clone, and pass it for the HelmChart b. The HelmChart then uses to create a PV & PVC for the DB Pod.

Considerations for large clusters

A cluster is a set of nodes (physical or virtual machines) running Kubernetes agents, managed by the control plane. Kubernetes v1.22 supports clusters with up to 5000 nodes. More specifically, Kubernetes is designed to accommodate configurations that meet all of the following criteria: No more than 110 pods per node No more than 5000 nodes No more than 150000 total pods No more than 300000 total containers You can scale your cluster by adding or removing nodes.
