Hi,

Anyone can advice how to retrieve accurate information to determine the overhead and size the hardware requirement (CPU, RAM, Storage, Network) by calculation for docker container APPs like elastic LB, fault tolerance which running on Kuberbnetes orchestration layer to design 500000 live video feed coming to share the load on the bare-metal design?

Tks

I have setup Code Pipeline to build a docker instance and deploy it on a ECS cluster, I have created my buildspec.yml and everything is working, however I need to adjust my buildspec.yml to print image definitions that setup a health check but so far its not working. Here is my current code for my buildspec.html

version: 0.2

phases:
  install:
    commands:
      - echo Entered the update phase...
      # Updates Docker Instance
      - apt-get update -y
  pre_build:
    commands:
      - echo Logging in to Amazon ECR...
      - aws --version
      - $(aws ecr get-login --region ap-southeast-2 --no-include-email)
      # ECS Repository URI
      - REPOSITORY_URI=###########.dkr.ecr.ap-southeast-2.amazonaws.com/###########
      - COMMIT_HASH=$(echo $CODEBUILD_RESOLVED_SOURCE_VERSION | cut -c 1-7)
      - IMAGE_TAG=${COMMIT_HASH:=latest}
  build:
    commands:
      - echo Build started on `date`
      - echo Building the Docker image...          
      - docker build -t $REPOSITORY_URI:latest .
      - docker tag $REPOSITORY_URI:latest $REPOSITORY_URI:$IMAGE_TAG
  post_build:
    commands:
      - echo Build completed on `date`
      - echo Pushing the Docker images...
      - docker push $REPOSITORY_URI:latest
      - docker push $REPOSITORY_URI:$IMAGE_TAG
      - echo Writing image definitions file...

      - printf '[{"name":"website","imageUri":"%s","healthCheck":{"retries":3,"command":["/bin/bash curl -f http://localhost/ || exit

 aws configure set aws_access_key_id default_access_key xxxxxx
 aws configure set aws_secret_access_key default_secret_key xxxxxx
aws configure set default.region us-west-2
 
aws s3 cp s3://mariadbs3bucket/test.txt /test

 mysql -u xxx-pxxx --host xxx -P 3306  --socket=TCP/IP  -e "USE myDB; insert into myDB.tt values(50000);"

Hi Experts,

   I got a server which runs applications with docker and aws, running from console(putty).  The command to run is as follows:-

docker run --name ts_pull ${ts_environment[@]}  -d  --restart always 1234656458.dkr.ecr.ap-southeast-2.amazonaws.com/harvest-ts:1.0.2 start pull

Select all Open in new window

I can understand 1234656458.dkr.ecr.ap-southeast-2.amazonaws.com/harvest-ts:1.0.2 is from aws.  Can any tell me how this container application is pushed to aws?

From the documentation I found Dockerfile is available, from which the docker image is built.  I don't understand how to push this to aws and run with the docker.

Please throw some light over it.

with many thanks,

Bharath AK

Hi,

I have a task in AWS that is started by ECS. I have developed a Cloudformation script that creates the ECS cluster, service, task definitions and containers.

The EC2 instances (2 to begin with) are initiated and are healthy. ECS then creates the tasks on each EC2 instance. However, have 1 minute, the tasks are stopped by ECS and it tries to recreate it. I presume this is something to do with the scheduler on AWS and not getting a healthy check back.

It is a node app running on port 300 which is mapped to the container. If I login to the EC2 instance and do a simple curl 127.0.0.1:32XXX (host port) then I get "no reply from server". Ok so it is something wrong with the image or container.

However, if I launch my own container of the same image publishing the ports ("docker run -d -p 32810:3000 <image> yarn start") and then do curl 127.0.0.1:32810 then I get a response from the server.

I cannot figure out how to debug this as there are no logs with any errors. Anyway..(I created the one on port 32810) the image is the same in both. I can only figure it is something to do with what the ECS agent does when it boots a task.
