Thanks for the feedback! :)

how about we extend this crash course videos to be a hashicorp stack series, where we get crash courses on all hashicorp products. (nomad, waypoint, ...)

This was an Excellent course on learning Service Mesh, Terraform, EKS and Consul. One of the feedback was the terraform destroy did not delete subnets due to the fact that Elastic Load Balancers was not deleted, which prevented the subnets from being deleted. I have to manually delete ELB to remove the subnets. It's weird. It's quite possible because these 3 ELB are not declared resources in terraform, and it's automatically created for managed node groups. Another question is why you created public subnets and what is the purpose? Is it for IGW only? EKS are in private subnets. Consul is deployed in EKS. Maybe I missed something. Again, thank you so much, Nana.

Please show us how to connect to an vm :) thanks for all your vids

can you please make a video on collecting infra level metrics & logs from kubernetes cluster using opentelemetry using deamonset mode (without doing instrumentation to application/microservices). And View those metrics & logs in grafana and store those metrics & logs in Storage Accounts &/ Database. Is it possible?

Hello @TechWorldwithNana could you do the same concept with istio please ? thanks in advance

Thank you - Excellent - I love to know the matrix data before and after implementing the consul on a kubernetes cluster - like " kubectl top nodes " - Just to see, how much resources in terms of CPU and memory does consul consume . also can we live implement consul on a production kubernetes cluster ? with out deleting pods.

in production, you can do it by increasing the number of replicas of the services and removing the instances without proxies. This way you won't have a down-time.

Hello Nana please what is the recommended order of deploying consul? Do you deploy the application manefest files first before the consul helm chats or vice versa? Thanks so much for your efforts and may you find the energy to continue doing what you are doing for the tech world

You can deploy in any order you want. You can deploy the service mesh in the cluster even after you have deployed all your applications and services without any issue.

@joshwolfer

If you deploy Consul after your application pods, you just need to destroy the application pods and let them restart. They'll come back up with the Consul components. You'd need to restart them anyway for annotation changes to take effect.

Welcome back

is that also way for multi region deployment?

Any playground interactive realtimr projects labs available ??

I came across a problem, I am not sure how to address this. 18 VMs running applications and databases. 3 separate VMs (with bit higher capacity for now) are hosting docker swarm ready to host those applications from the VMs; but none of the apps in either platforms are mesh aware; I am trying to use consul's DNS service and custom python background service to listen to docker events and call consul API to [de]register services. Its a mess and very errorprone; I want to simplify this deployment of apps in docker (we're using private registry and its an airgapped system). Also we're running debian 12. No enterprise support. How do I also ensure proper service discovery to-from the legacy platform into the new environment? and the sysadmins are inclined towards swarm only, no kubernetes; please help!

Yes, service mesh will be included in the DevSecOps bootcamp in part 2. Scheduled to release start of next year. But I don't have a separate deep dive course only on service mesh.

Thank you for the great video first. To simulate failover, you delete the deployment. Is there no K8 object in this setup ? I would think of deleting the service object instead. And then the service disappears from EKS Consul GUI. If there is a K8 service object, I'd expect the service appear as failed. Thank you.

I was waiting for this what took you so long
