ECS Service - Automating deploy with new Docker image

Question

I want to automate the deployment of my application by having my ECS service launch with the latest Docker image. From what I\'ve read, the way to deploy a new image version is

Answer 1

#!/bin/bash
SERVICE_NAME="your service name"
IMAGE_VERSION="v_"${BUILD_NUMBER}
TASK_FAMILY="your task defination name"
CLUSTER="your cluster name"
REGION="your region"


echo "=====================Create a new task definition for this build==========================="
sed -e "s;%BUILD_NUMBER%;${BUILD_NUMBER};g" taskdef.json > ${TASK_FAMILY}-${IMAGE_VERSION}.json

echo "=================Resgistring the task defination==========================================="
aws ecs register-task-definition  --family ${TASK_FAMILY} --cli-input-json  file://${TASK_FAMILY}-${IMAGE_VERSION}.json --region ${REGION}

echo "================Update the service with the new task definition and desired count================"
TASK_REVISION=`aws ecs describe-task-definition --task-definition  ${TASK_FAMILY}  --region ${REGION} | egrep "revision" | tr "/" " " | awk '{print $2}' | sed 's/"$//'`


DESIRED_COUNT=`aws ecs describe-services --cluster ${CLUSTER} --services ${SERVICE_NAME}  --region ${REGION} | jq .services[].desiredCount`
if [ ${DESIRED_COUNT} = "0" ]; then
    DESIRED_COUNT="1"
fi

echo "===============Updating the service=============================================================="
aws ecs update-service --cluster ${CLUSTER} --service ${SERVICE_NAME} --task-definition ${TASK_FAMILY}:${TASK_REVISION} --desired-count ${DESIRED_COUNT} --region ${REGION}
