@@kodjoviamedimele3066 Yes I want to create a complete GitHub actions course, but we don't have a fixed deadline for it yet :) Thanks for your suggestion though
Your work is absolutely great! You are bringing huge value to DevOps comminity. I love your explanations where you use the real life example to present the technology concept. Also love your 'first conxeption, then technology' approach.
Thank you Nana for the most comprehensive course on Consul service mesh. You explain each and every concept in the simplest possible way. Looking forward to more such courses. Great job.
This is a great video and well explained. I could understand every aspect and got an insight on how to apply in production environment. You are one the best DevOps Tutor out there. Great Work @TechWorldwithNana 👍
This is the best video I've seen so far for setting up mutliple Consul datacenters. Thank you! Could you do one that does not use kubernetes? The thought is that this is doable without kubernetes for those that have dockerized apps/services and would like to use Consul and maybe Nomad to start their "cloud" journey.
Nana, Great insites.... Your explanation and Animation mach, make me understood this Topic... Its great efforts! I appreciate on the behalf of all learners❤
You are a great teacher!. Liked your way of teaching with concepts first. Just short of words for this funtastic video. Any plans to come up with video for K8s new Gateway API
This was an Excellent course on learning Service Mesh, Terraform, EKS and Consul. Again, thank you so much, Nana. I've made it to the end. Nana, can you create a video about sidecar-less service mesh? Cilium and Istio Ambient Mesh support it. It will save a lot of money without sidecar proxies. Thank you. The only caveat is the failover portion did not work despite the fact that I created service resolver, exported the shippingservice, etc.
Super informative, thanks! Would be just amazing to see practical integration of consul with others Hashi tools: nomad and vault (probably using same google’s demo services). Oh, and something about self-hosted distributed storage in clusters please (nomad/k8) :)
@@TechWorldwithNana thanks for this course. Please could you create a complete end to end GitHub actions course to deploy microservices into kubernetes as you mentioned in the GitHub actions crash course?
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.
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.
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.
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?
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, ...)
I mean, in order to connect two clusters using consul or whatever, don't we need to specify somewhere a valid lb ip or dns name of proxy service of counterpart on every peers?
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 happy to hear! Was thinking to create a JavaScript crash course for beginners. What would you like to see in such a tutorial? Basics of variables, data types, functions etc?
@@TechWorldwithNana I want to learn from beginner to advanced I have to learn everything about it, I am very fond of coding, Please Teacher create complete course beginer to advance. I'm glad you replied, I hope to come up with a complete course javascript on this soon

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.
A really good point. Failover on service only to me. If I deleted the deployment, failover did not work. However it worked if just deleting the shippingservice service. Thanks,
Thank you nana , but too much abalogy makes me feel sleepy, we can understand better if you just avoid too much analogy, like ... apartment ..building...etc , good job !

is that also way for multi region deployment?

Welcome back
Hi. How peers' endpoints were specified? lke was a valid dns name? I don't think so
I mean, in order to connect two clusters using consul or whatever, don't we need to specify somewhere a valid lb ip or dns name of proxy service of counterpart on every peers?
Please show us how to connect to an vm :) thanks for all your vids

How to make life complicated when you can just use a single AWS
U need more exposure to the world of DevOps.
Enterprise application networking with redundancy is rather complicated.
why u r not showing your face , if u show your beautiful face it will be more easy to understand the concept
