I'm crying tears of joy! I hope you and your family experience ten thousands suns and moons of happiness and prosperity!

[@MatthewReader]

I can't begin to tell you how helpful this video was and how excited I am to finally get a 200 OK status code from the health check of my ECS service! I was getting held up on the security group not allowing traffic from the load balancer.

[@_axtone]

Amazing video! I spent like two weeks trying to configure an ECS cluster with no success until I found this video, thanks for such great content and explanation

[@andrewa3216]

This was by far the best and most detailed tutorial ive seen of this

[@cristian20035]

this is the BEST video I've ever seen about AWS ECS with Fargate

[@companyjoe]

This is the only resource in the whole internet that has been useful on this subject. Not only is this needed and useful, it's super clearly explained! Some people just deserve to have all the money they can eat for the rest of their lives for one good deed and this would be one of them. Why not? There's a lot of one hit wonders who have earned that.

[@mankaranbedi8927]

You won't even realize the amount of headache this has saved me. Liked and subbed. Thank you very much.

[@gaurav.taneja]

Best tutorial among all the videos on this topic!! Really helpful, thanks a lot for this video.👏

[@karantoor8508]

I go back to this video again and again. Very informative!

[@shivamanand8998]

Thank you for taking hours to figure out things. You saved a lot of our time.

[@BeABetterDev]

You're very welcome Shivam!

[@rossbrook9182]

This is a fantasic video, clearly explained. Also highlighting the key issues. Thankyou

[@jameswoodruff6920]

Thanks so much. This is great info. Tips like choosing a target type of IP instead of Instance for the load balancer are invaluable.

[@vk2875]

Excellent detailed hands-on walk thru !!! Thank you !!!

[@BeABetterDev]

Thanks V! You're very welcome!

[@alejopaullier5538]

Fantastic video, best I've seen on the topic so far. Keep them coming!

[@BeABetterDev]

You're very welcome DAvid!

[@christopht.3687]

Thank you very much for that great explaination even for the routing section. It's really helpful to configure target groups properly if you use Fargate the first time.

[@BeABetterDev]

You're very welcome Chris! Glad you found it helpful - the routing details stumped me for hours.

[@tigrangevorgyan3584]

Thanks for the video!

[@bhdimitrov]

I can't express my gratitude. I wouldn't do it without your help!

[@BeABetterDev]

You're very welcome Boyan!

[@vasan9017]

Thank you. Was breaking my head for half a day with the instance Vs ip. You're my saviour

[@BeABetterDev]

You're very welcome Vasan! I was scratching my head with that for a few hours as well :)

[@freddyescobar7228]

Thank you soooo muuuch for this video. I was strugling with the whole Load Balancer/Securit group stuff. Appreciated

[@PaulPetersVids]

Thank you kind sir. Saved me a lot of headache. Quick note: at 15:44 you are correct in saying use the SAME subnets for the service as the ALB. I had the wrong ones and was getting timeout issues when connecting to the DNS of the ALB. Thanks again!

[@shabarinathk8954]

thank you for saving my life/job/career

[@PaulliMr]

Amazing tutorial! Thanks for a clear explanations :)

[@scchengaiah4904]

Thanks alot for this great video. Explanations regarding the constraints faced really helps to stay on track while setting up the configuration

[@yogeshkaushik9861]

Really appreciate you taking time and creating this video, was stuck on target group error your video helped a lot!!

[@BeABetterDev]

Glad it helped Yogesh!

[@maconsuckow5214]

This was awesome! Helped me out a bunch!

[@johnkirubakaranabraham7495]

Very useful and Really appreciated

[@drjoaoventura]

16:17 "... the load balancer stuff I spent hours trying to figure out". I have no words to express my gratitude. I will gladly join Patreon after watching it. On our platform migration from EC2 instances to ECS Fargate, I had countless bizarre problems. Your video covered the most tricky I faced (and are poorly documented by AWS). Only this exact step cost me 16 hours. Soon I will dig into your channel searching for a pure AWS EKS Fargate setup.

[@BeABetterDev]

You're very welcome JP! I struggled for many many hours as well so don't feel too down on yourself. I'm glad I was able to help, though. Cheers!

[@jeanfrancois4157]

Same waste of time for me with the NLB setup that come without SG (layer 3 of course) nor inbound IP pour to setup in the Target servers SG, that cause health-check fail !

[@sarashaikh1666]

Thank you very much! great video

[@nickmorton5595]

Great video!!!

[@alashish]

Thanks mate you saved me, i went crazy while setting this up and things were not working and those useless logs. Finally its working👍

I was following a Udemy course, but they had a recording of older console UI, which confused me. but I was able to follow you easily and was able to set up ALB, a couple of containers. Thanks

[@misaelpereira9679]

Maaaan you saved my life, i cofigured wrong my balancer putting the same port as the target group, thanks!

Thank you, so much. You really saved me from a very big problem. 👍🖖 edit- your pronunciation is like Quinn from Dexter: season 4

[@syedkausaralinaqvi2311]

This is one of the best tutorials on youtube. Thanks Sir! Though I still got some issues which was related to Health Check. Load balancer expects 200 status from the endpoint we specify in the Health Check path. My server did not have an endpoint with "/" so I was supposed to change that path to some other route so that the load balancer could be able to get 200 status in return.

[@TheMillw0rm]

man i had a hard time finding out how to make ELB work with ECS , THANK YOU!! something to add to this video is that at moment 25:08 you could get the result back from fargate but since Docker container exposed port was 80801 not 80 to access it directly with IP or public DNS you had to include that port .

[@BeABetterDev]

You're very welcome javad!

[@jezenielzapanta9255]

Thanks!

[@BeABetterDev]

Thank you so much!

[@yitznewton]

I got all the way up to a running 2-container web app on my own, but trying to set up the LB defeated me. Thank you so much for making this!

[@BeABetterDev]

You're very welcome!

[@lightwasright9369]

Thank you for this, I ran into the same issue where I also forgot to allow the security group for my services to receive connections on the container port. This video was extremely helpful

[@BeABetterDev]

Glad I could help!

[@EspoirMurhabazi]

Brooooo, thanks you for making this clear and remove all the confusion I was having.. one improvement, can you make a videos on how to create the the infra with the cdk with any language so that we can make all those clicks to the console easy?

[@ketanlokhande3557]

Thank you so much. For Fargate it's IP, Not Instance.. Big help. Wonderful session.

[@BeABetterDev]

You're very welcome and thanks for the clarification!

[@FelipeDouradinho]

You saved me regarding the Target Group not showing up!!! Aws need to do something about this shit, some warning or something else

[@BeABetterDev]

Glad I could help Felipe!

You're welcome JR!

[@alxx736]

You saved my life. No joking

[@vortexwolf_]

Omg, this f button at 16:50... now it works, thx!!!

[@BeABetterDev]

Glad I could help!

[@eleandro]

I lost 2 days on it, and just investing 22 minutes you answered all my questions. If you're new to this, remember also that your Fargate and task must be part of public subnets and not private one since public subnets can reach the internet.

[@BeABetterDev]

Glad I could help! It was such a pain figuring this out the first time :P

[@eleandro]

I’m watching your AWS playlist and learning from it. Thank you for sharing your knowledge with us!

[@deojefflai6826]

Thank you so much for uploading this. I spent hours trying to figure out what's with the failing healthcheck, and you're totally right about the logs being useless lmao.
