How to Deploy a Docker App to AWS using Elastic Container Service (ECS)

[@AlexeyYanovski]

For anyone getting this error: CannotStartContainerError: Error response from daemon: OCI runtime create failed: container_linux.go:370: starting container process caused: process_linux.go:338: getting the final child's pid from pipe caused: read init-p: connection reset by peer: unkno The cause is there's not enough memory assigned for your Task. If you followed along to the video, in task definition, change memory from 1 to 512 and CPU to 512 as well. Hope it helps

[@BeABetterDev]

Thanks for pointing this out Alexey! I've had a few folks comment on this same issue and wasn't sure of the reason. Glad you were able to figure this out and share with others. I'm going to pin this to the top so others can benefit. Cheers!

[@xuebosun766]

It doesn't work for me.

[@xuebosun766]

I am using GitLab Container registry. ARN seems not working as well.

[@xuebosun766]

GitLab returned an error "unauthorized: HTTP Basic: Access denied You must use a personal access token with 'api' scope for Git over HTTP. You ca". Not sure how to set GitLab personal access token in AWS secret used for ARN.

[@xuebosun766]

I just made it work. I need personal access token as password. :)

[@go_better]

Man! I wanna hug you! I suffered for about a month through bullshitery guides from amazon on how to do it! But you explained it so simply! Now I will need to make a pipeline with autodeploy. I hope you'll have videos on that topic. THANK YOU once again for such clear explanation.

[@BeABetterDev]

You're very welcome !!!

[@miguelchiquin9354]

You saved my day! Thanks. Specially when you showed that the public IP wasn't accesible because of the default security group that the instance had attached.

[@BeABetterDev]

Glad I could help!

[@andremazetto]

How could one figure all this out without this tutorial... the amount of steps are insane and the AWS CLI is so not intuitive! thanks for demystifying it for us

[@BeABetterDev]

Thanks so much ad ma! I feel your pain - doing this the first time I almost wanted to rip my hair out :P

[@7enso]

This was amazing, I've ben looking for this exact kind of tutorial for ages and it really cuts through the verbose aws documentation! Thank you so much!

[@BeABetterDev]

Glad it helped!

[@ngneerin]

Have been looking for such a tutorial since two months now

[@BeABetterDev]

Glad you enjoyed!

[@daCorasla]

Thanks for this awesome tutorial! For anyone actually trying to deploy some kind of code that needs to be built on the machine, please take EXTRA care in making sure that the instance type has more than enough memory to actually build the app and start it properly. Figured this out only after ssh-ing into the EC2 container and interactively running commands on the docker image to try and manually build the project

[@cmlaio8119]

Thank you for the video, I was about to give up trying to run a container from a Docker image because I could not understand Amazon's documentation. This video was incredibly helpful.

[@BeABetterDev]

1:30 *task* 3:33 *login to ECR* 4:18 create repository in ECR 4:46 upload the built image onto ECR repo 4:52 tag image: docker tag 5:17 push 6:24 create a cluster

[@YannMjl]

Thank you for sharing. This is was greatly done, straightforward and so much easy to understand. Thinking on the monitoring, What are some things that you'd recommend to be monitored for apps running on ECS, whether it's setup using EC2 or Fargate?

Love your video!! Thanks!!..quick and easy !...with no garbage! God Bless you! You won one subscriber!

[@BeABetterDev]

Thanks so much Israel and welcome to the channel!

[@kdeng7]

Thank you for the great tutorial! Based my observation and the time of this video, I guess you were using an Intel Mac? For anyone also on M1 chip Mac: I use Apple M1 chip Mac and it creates ARM64 image by default. It’s not runnable on EC2 t3.micro instance. If you still want to run the an ARM64 image with EC2, you’ll need to select instances powered by Graviton, for example t4g.micro, which can run ARM64 workload. OR you need to run `docker buildx build` to build an amd64 image at the beginning.

[@ramirez368]

Super nice....thanks, vey useful, especially the task definition part.

[@darrenklein6090]

Thanks for this helpful tutorial, it got me up and running! However, one issue that I ran into was trying to run multiple clusters (one for a staging release of my app, one for production) - I found that if I put both clusters on the same subnet, the second cluster wouldn't start an EC2 instance; putting them on different subnets resolved that. This is my first foray into AWS and I have about zero experience with networking, so maybe that's totally expected and normal - but if you're like me and you're just starting to learn your way around, maybe this'll be helpful for you.

[@BeABetterDev]

Hi Darren, I can't say I've personally experienced this issue but thank you for sharing your knowledge! I'll keep this in mind next time I set up ECS. Cheers!

[@daabakedpotato]

Just want to give a heads up to anyone running a react container and have issues with your task exiting after starting. The error I'm talking about it "essential container in task exited". If you are facing this issue you need to turn on the pseudoTerminal within your task so it doesn't exit immediately while react is starting up. 1. Find your task and click "create new revision" 2. Scroll all the way down until you see "volumes" and click "Configure via JSON" 3. Find "pseudoTerminal" and set the value to "true" 4. Assign the task again and everything should be working fine now

[@zachkurdi3178]

thank you for this i had this problem and i tried the solution but it still exists even after modifying the json file edit: i created another revision with 512mb and that seems to work

[@piyushpandey4042]

[@viniciusalvess]

The video was very helpful. Thanks for sharing such a great content. But it is confusing the part you call the image and the repository 'test', having them with the same name makes the watcher confused if they are using other names.

[@barrypun6979]

Great this tutorial worked for me! Question in mind tho, do i need to change SG and network mode when deploying to ElasticIp and Route53?

[@BeABetterDev]

Great to hear Barry! In order to make your instance publicly accessible, you would need to make your instance able to receive traffic from the public internet (inbound rule with 0.0.0.0/0). Hope this helps.

[@Kimchinabe-p7c]

Hi great video. I followed this along but got stuck where the task was pending status. Can you show me how you fixed it exactly? I was following exactly what you were doing.. I don’t know what typo you made.. is that container name ?

Thank you Sir Very much for your guidance

[@enricosaccheggiani3192]

The Flask application works without any problem . Thanks a lot for this important example.then I have tried to deploy a django application on a ecs container following your instructions. I am afraid that the T2micro is too small to load a imagine of 1.24 Gb .

[@user-re7tb3vy5l]

4:10 If you cannot login, you need to allow access for "AWSAppRunnerServicePolicyForECRAccess" at AWS IAM console. I watched AWS CLI tutorial, but I struggled because I didn't know about "AWSAppRunnerServicePolicyForECRAccess".

[@user-re7tb3vy5l]

also, I allowed access for "EC2InstanceProfileForImageBuilderECRContainerBuilds". I'm not sure which is necessary to login.

[@scigama71]

Excellent..Thank you. How much do you think it would cost for the application you wrote to run on ecs for a month?

[@BeABetterDev]

Hi James, if you use this guide the costs zero. Be sure to use the Free Tier eligible EC2 instances (provided that fits your use case) and you can try this out with minimal costs. Also, be sure that your docker image is below 500mb in size so that you can stay in the free tier. Hope this helps, Daniel

[@mikecmw8492]

Do you have a video that shows how to add --env to the docker run command? I need to do this although we use terraform to actually provision the fargate container. Maybe terraform adds those env vars?

[@tkoyluoglu3]

Great tutorial, I have a question. I have a similar set-up and wonder if there is any way to handle clients loosing connection each time you make a deployement? E.g every time I deploy the users that were authenticated and signed in to the site gets kicked out since the container with redis gets cleared

[@BeABetterDev]

Hi Tolga, this is an interesting problem. Is it possible your Redis instances can dump state onto disk so the caches can be recovered on startup? Else, you may want to use the dedicated AWS ElasticCache service with Redis. Hope this helps

[@tkoyluoglu3]

@@BeABetterDev Hmm that could be possible, I will have to look into it. Thanks for the tip!

To anybody using an M1 Mac and getting "(Essential container in task exited)" error, I realized I was building with arm64 and the architecture of the ECS Cluster is AMD64. To solve this issue, use "docker buildx build --platform linux/amd64 -t app ." and then tag it again and publish it to the repository. Wasted one hour on this.

[@chaohsining8168]

I stuck for 1 day. You saved my day!

[@alexandrevalente9994]

Hello, Great video and cristal clear but, now let's say I would like to avoid all these IDE manipulations so I can reproduce the steps automatically without getting into the AWS console ? Why do I ask this? Because it is easy to miss a step, it is almost impossible to pass the knowledge consistently to someone else and therefore hard to maintain a procedure. Thanks.

[@BeABetterDev]

Hi Alexandre! Great question. To recreate a stack consistently, the best practice is to use cloudformation / cdk. As a visual learner, I do think there is value to see it done in the console. Here are some videos on Cloudformation / CDK you may find helpful: kzbin.info/www/bejne/ZoTLaoKviKismJY and kzbin.info/www/bejne/pJ3FaaylbLiNaKs Cheers
