aws cli ecs scale

Then. With a metric value of 66 and a target value of 100, the ASG will scale in to reduce N from 3 to 2. AWS Fargate is a technology that you can use with Amazon ECS to run containers without having to manage servers or clusters of Amazon EC2 instances. the documentation better. Sometimes, customers would resort to custom tooling such as Lambda functions, custom metrics, and other heavy lifting to address the challenges, but there was no single approach that could work in all situations. The reason is that this would not allow us to achieve design goal #3. Amazon ECS and AWS Fargate Introduction First things first Lab 1. Specifies the Amazon ECS cluster name to use. Please refer to your browser's Help pages for instructions. Consider the example shown in Figure 4. Sometimes, customers would resort to custom tooling such as Lambda functions, custom metrics, and other heavy lifting to address the challenges, but there was no single approach that could work in all situations. The maximum number of container instances that Amazon ECS will scale in or scale out at one time. (It’s important to note that, even though in this particular case the four running tasks could theoretically run on a single instance, M is computed solely based on the number of instances currently running tasks – not on a hypothetical optimal distribution of tasks on a minimal number of instances). (Target tracking scaling has a special case for scaling from zero capacity, where it assumes for the purposes of scaling that the current capacity is one and not zero). At a high level, the logic is quite simple: Figure 1. through aws-cli: ~ $ aws ecs update-service ... --service xyz --desired-count 0 If you want to do this in Dev I suggest you run this UpdateService either manually, or from a cron-job, or from a scheduled Lambda function. I've since switched to aws-cli for this as it seems a bit more robust. The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider.. For example, if you have a strategy that contains two capacity providers and both have a weight of 1, then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Unfortunately, this is often impractical or impossible – the tasks might all have different resource requirements, placement constraints and placement strategies, and the ASG might even have multiple instance types with different vCPU, memory, and other resources available. This is where managed termination protection comes into the picture. (It’s important here to note that that M, which is CAS’ estimate of how many instances are needed to run all of the tasks, is not based on the target value of the scaling policy). Calculate M as the maximum value of step 3 across all task groups. How can I do that? Step 2. B. create-capacity-provider: Used to create a new capacity provider. Configure AWS CLI for the user you just created above. How to download the latest file in a S3 bucket using AWS CLI? If enabled for a capacity provider, ECS will protect any instance from scale-in if it is running at least one non-daemon task. AWS Fargate is an engine used to enable ECS to run containers without having to manage and provision instances and clusters for containers. the configure command. The Amazon ECS CLI can only manage tasks, services, and container instances that So, in order to achieve all three design goals, CAS relies on AWS Auto Scaling in addition to instance termination protection. Installing AWS-CLI. 1 answer. Reasonable. Given a metric and a target value for that metric, the scaling policy will increase/decrease the size of the ASG, in other words it will adjust N, as the metric increases and decreases, with the goal of keeping the metric close to or equal to the target value. Instead, the scaling policy will adjust N to achieve a value close to the target value, with a preference for the metric to be less than the target value if possible. Scale the adoption platform monolith with an ALB and an ECS Service. Ideally, we would like this process to complete in one step because each step requires time to complete, so the ASG can get to the correct size more quickly if CAS can scale to the correct size in one step. Now that one instance is free of non-daemon tasks, the scaling metric is updated:  M=2, N=3, so CapacityProviderReservation=66. Figure 4. With AWS Auto Scaling, your applications always have the right resources at the right time. This is still appearing in the exam. How M is calculated is key to how CAS actually does the scaling. ... amazon-web-services; aws-ecs; 0 votes. aws_profile. Design goal #1: CAS should scale the ASG out (adding more instances) whenever there is not enough capacity to run tasks the customers is trying to run. I’m going to open up my terminal and create a cluster. 1 Comment on AWS Application Auto-scaling for ECS with Terraform Update : Target tracking scaling is now available for ECS services . The cluster has one capacity provider, with an ASG with three instances (as shown above), all of which are running tasks. Figure 5. so we can do more of it. If you need your service stack to have associated tags, you can do so via the --tag-file parameter. For each group with identical resource requirements, calculate the number of instances required based on each of the largest instance types identified in step 2 if a. Specifies the AWS profile to use. Given a target value of 100 for CapacityProviderReservation, the scaling policy will adjust the ASG size (N) up or down until N = M. To see why this is true, the equation CapacityProviderReservation = Target value (or equivalently M / N X 100 = 100), is only true if N = M.  If M changes, by either trying to run more tasks, or shutting down existing tasks, the scaling policy will adjust N to keep it equal to M. Scaling to and from zero is even possible: if M=0, meaning no tasks other than daemon service tasks are running, then N will adjust down to 0 also. Fetch the instance types and their attributes that the ASG is configured to use. The default behavior of the ASG may well terminate instances that are running tasks, even though there are instances not running tasks. Specifies the AWS Region to use. As we demonstrate later, with a target capacity of 100, the ASG will scale out to M instances. A. Step 4. AWS Management Console. One of our goals in launching CAS is that scaling ECS clusters “just works” and you don’t have to think about it. Click here to return to Amazon Web Services homepage. Scale the tasks: ecs-cli compose --project-name ecsdemo-frontend service scale 3 \ --cluster-config container-demo ecs-cli compose --project-name ecsdemo-frontend service ps \ --cluster-config container-demo We can see that our containers have now been evenly distributed across all 3 … Thanks for the quick response - I can't be sure I did scale down with ECS CLI but the AsgMaxSize is currently at 1. cluster_name. This means that half of the instances will not be running any tasks. We run a couple of cli calls to get the Auto Scaling group details which is required for the next command where we create the capacity provider. instances) or scale in (decrease the number of instances) your cluster. To interact with AWS, aws-cli and awscli-plugin-endpoint need to be The burden of managing your own cluster management system is abstracted with the Amazon ECS service by passing that responsibility over to AWS, specifically though the use of AWS Fargate. The metric updates, because M = 4 and N = 4, so CapacityProviderReservation = 100. Thanks for the quick response - I can't be sure I did scale down with ECS CLI but the AsgMaxSize is currently at 1. The Docker Compose CLI enables developers to use native Docker commands to run applications in Amazon EC2 Container Service (ECS) when building cloud-native applications. This means, for example, if you call the RunTask API and the tasks don’t get placed on an instance because of insufficient resources (meaning no active instances had sufficient memory, vCPUs, ports, ENIs, and/or GPUs to run the tasks), instead of failing immediately, the task will go into the provisioning state (note, however, that the transition to provisioning only happens if you have enabled managed scaling for the capacity provider; otherwise, tasks that can’t find capacity will fail immediately, as they did previously). One task is stopped (due to service scaling for example). No further scaling is required. Calculate M as the minimum value within each task group and maximum value of those across all task groups. On your behalf, Amazon ECS creates an AWS Auto Scaling scaling plan with a target tracking scaling policy based on the target capacity value you specify. Hi Team, I have created an ECS cluster in AWS. browser. At the present time, a maximum of 100 tasks can be in the provisioning state for any cluster, and provisioning tasks will wait for capacity for between 10 and 30 minutes before transitioning to “stopped.”. At this point, M = 3, N = 3, and CapacityProviderReservation = 100. See the User Guide for help getting started. If there is at least one task in the provisioning state, then M > N. We describe in more detail below exactly how M is calculated in this case. Enables you to use the AWS credentials from an existing ECS recognizes that additional capacity is available, and places the provisioning tasks on the new instance. In this example, the ECS-instances are scaled down to 2, and then the services are scaled down to 2. ecs-cli compose --project-name microgateway --file docker-compose.yml service \ scale 2 --cluster microgateway-demo --region us-east-2 In other words, if you aren’t using any other scaling policies, then the desired count of the ASG should be M (the number of instances CAS has determined are needed). cluster. This is an example project on how to use AWS ECS … Scale in would never happen if we included daemon services). Design goal #2: CAS should scale in (removing instances) only if it can be done without disrupting any tasks (other than daemon tasks). If you have requests for new functionality or want to see our roadmap, please visit the AWS Containers roadmap on GitHub. The oam-ecs CLI provisions two of the core OAM workload types as Amazon ECS services running on AWS Fargate using AWS CloudFormation. AWS provides a set of commands that can be run on AWS-CLI (AWS Command Line Interface) to manage your services. The ASG has three instances (purple boxes, N = 3), each running non-daemon tasks (green boxes). Given this new task lifecycle behavior, how does CAS determine the desired number of instances M? On your behalf, Amazon ECS creates an AWS Auto Scaling scaling plan with a target tracking scaling policy based on the target capacity value you specify. --cluster, -c Hi Team, I have created an ECS cluster in AWS. Since the third instance is not protected from scale in, it terminates. Up until recently, ensuring that the number of EC2 instances in your ECS cluster would scale as needed to accommodate your tasks and services could be challenging. First time using the AWS CLI? Target values less than 100 enable spare capacity in the ASG. AWS Auto Scaling is available at no additional charge. Scale the tasks: ecs-cli compose --project-name ecsdemo-crystal service scale 3 \ --cluster-config container-demo ecs-cli compose --project-name ecsdemo-crystal service ps \ --cluster-config container-demo We can see that our containers have now been evenly distributed across all 3 … For example, if you set the target value to 50, the scaling policy will try to adjust N so that the equation M / N X 100 = 50 is true. aws ecs register-task-definition --cli-input-json file://task-wordpress.json Line 6 maps port 0 to port 80 on each container, which means a random port on the host. Let’s look at the scenarios in Figures 1, 2, and 3 again. aws ecs create-service --cli-input-json file://talk-service-ecs.json Check the service has been correctly registered by navigating to EC2 Container Service > conference-cluster > Services. AWS CLI. n [--cluster cluster_name] I was suffering that Terraform scripts (HCL) tends to be very long because it defines infrastracture atomically and manually, so I was looking for some tools to reduce them. With managed termination protection, ECS will prevent instances running non-daemon tasks from terminating due to ASG scaling in. Lastly, if N > M, scale in is possible (but not necessarily required) because you have more instances than you need to run all of your ECS tasks. First time using the AWS CLI? Three instances, two of which are running tasks. Now, the first two instances are still protected from termination but the third is not. AWS (Amazon Web Services) is a secure cloud services platform, offering compute power, database storage, content delivery, and other functionality to help businesses scale and grow. For example, a target value of 10 means that the scaling policy will adjust N (within the limits available) so that about 90% of your ASG’s instances will not be running any tasks, regardless of how many tasks you run. We can’t have multiple containers listen on port 80. Specifies the number of instances to maintain in your We did this earlier in this section when we added the EC2 capacity to the ECS cluster. job! ecs-cli scale --capability-iam --size AWS CLI tools, available from AWS. ECS clusters could not always scale out when needed, and scaling in could impact availability unless handled carefully. ECS clusters could not always scale out when needed, and scaling in could impact availability unless handled carefully. The scaling behavior is built on the assumption that the “metric value must increase or decrease proportionally to the number of instances in the Auto Scaling group.” CapacityProviderReservation is designed for this assumption. Note that this does NOT prevent a Spot Instance from being reclaimed, or the instance being terminated manually; it only prevents the ASG from terminating the instance due to scaling. On the other hand, if N < M, scale out is required because you don’t have enough instances. In this case more instances are needed to run the provisioning tasks, so M > 3; more work is needed to determine a desirable value for M. Figure 3. Note: In the AWS CLI version 1 the command is aws ecr get-login (without the -password). We know that M should be bigger than N, but how much bigger? AWS Fargate on ECS has to respect the default 1 task per second launch limit, and so time to scale from 1 to 3.500 tasks should be around 3.500 seconds, which is about 1 hour. Once the metric goes above the target value of 100, the scaling policy kicks in to adjust the desired count of the ASG upwards from N = 3 to N = 4. I want to describe the cluster with AWS CLI. I am running applications in production with AWS ECS Fargate provisioning with Terraform. ECS also provides the facility to scale up/down the number of tasks in the service. Since we can’t in general know the optimal value of M, CAS instead tries to make a good estimate. Ideally, CAS would calculate a value for M that is optimal – that is, no bigger and no smaller than it needs to be to run all provisioning tasks. Accepted values are numbers between 0 and 100. unit -> ... Information about a set of Amazon ECS tasks in either an AWS CodeDeploy or an EXTERNAL deployment. ECS CLI. In Figure 2, let’s suppose that M = 4, because we need one additional instance to run the three provisioning tasks. The tasks are still (briefly) in the provisioning state because ECS has not yet placed them on the instances. --aws-profile NOTICE CPUReservation and CPUUtilization alarms. AWS announced Cluster Auto Scaling for ECS in December 2019. CAS relies on ECS capacity providers, which provide the link between your ECS cluster and the ASGs you want to use. Managed scaling is enabled with a target capacity of 100, and managed termination protection is enabled. I’ve been working on setting up autoscaling settings for ECS services recently, and here are a couple notes from managing auto-scaling for ECS … Figure 2 shows a graphical example. CAS is more than just some new APIs; it encompasses a whole new set of behaviors for ECS, and I encourage you to keep this blog post handy so that you can better understand the behavior of your clusters as they scale. Firstly, I create two files. In the formula above, the number M is the part that CAS controls; in turn, M is driven by the customer’s tasks (both already running and waiting to run). ECS Cluster Auto Scaling (CAS) is a new capability for ECS to manage the scaling of EC2 Auto Scaling Groups (ASG). The AWS Copilot CLI is a tool for developers to build, release and operate production ready containerized applications on Amazon ECS and AWS Fargate. 1 Comment on AWS Application Auto-scaling for ECS with Terraform Update : Target tracking scaling is now available for ECS services . instances that weren't created by the Amazon ECS CLI, use the AWS Command Line Interface Apparently (as also becomes evident from the documentation), a so called task definition should encompass all of your containers that make up you stack.. i.e. ECS Service Level Autoscaling. Up until recently, ensuring that the number of EC2 instances in your ECS cluster would scale as needed to accommodate your tasks and services could be challenging. As I want to focus on realistic results for everybody, we will mostly test Fargate with the default rate limits. Use of CDK simplifies instantiation of AWS services such as ECS Fargate. Menu Discovering AWS with the CLI Part 2: ECS and Fargate 25 October 2019. Following is a list of commands that can be used for managing the AWS ECS service. Doing a little algebra, we see that N = 2 X M. In other words, with a target value of 50, the scaling policy will adjust N until it is exactly twice the number of instances that CAS has estimated are needed to run all of the tasks. Line 13 allows mount command to be run from the container, otherwise it will fail. As we show later in this blog post, the design of CAS meets all three of these goals. Specifies the name of the Amazon ECS cluster configuration to use. We’ll be configuring the SCM section of Jenkins a bit further down to get check out the code and build it. The metric will behave as shown in the picture below. Thanks! cluster_config_name. When managed scaling is enabled, Amazon ECS manages the scale-in and scale-out actions of the Auto Scaling group. In order to convert M and N into a metric that is compatible with target tracking scaling, we must obey the requirement that the “metric value must increase or decrease proportionally to the number of instances in the Auto Scaling group.” With this requirement in mind, our formula for CapacityProviderReservation is (as stated previously): There are a few special cases where this formula is not used. With no additional input, there is no way to guarantee that the instance running no tasks will be terminated; the third instance in Figure 4 may well be the instance that is terminated during the scaling action. --region, -r Some, but not all, of the provisioning tasks will get placed on the new instances. Note 1: Enabling CloudWatch Container Insights for individual Amazon ECS clusters using AWS Management Console is not currently supported, the feature can be enabled and configured only through AWS Command Line Interface (CLI). Update: if you still want to scale down the Fargate Service to 0 Tasks you can certainly do it through setting the Service's DesiredCount to 0.That can be done e.g. Scale the tasks: ecs-cli compose --project-name ecsdemo-frontend service scale 3 \ --cluster-config container-demo ecs-cli compose --project-name ecsdemo-frontend service ps \ --cluster-config container-demo We can see that our containers have now been evenly distributed across all 3 … Update: if you still want to scale down the Fargate Service to 0 Tasks you can certainly do it through setting the Service's DesiredCount to 0.That can be done e.g. Amazon ECS and AWS Fargate Introduction First things first Lab 1. Deploy the container using AWS Fargate Lab 3. Figure 3 shows a graphical example. Step 3. Let’s call this number M. Let’s also call the current number of instances in the ASG that are already running N. We’ll make extensive use of M and N throughout the rest of the blog post, so it’s important to have a completely clear understanding of how to think about them. How can I do that? AWS CLI allows you can use Linux shells, Windows PowerShell or … AWS Container Immersion Day > Amazon ECS and AWS Fargate > Scale the adoption platform monolith with an ALB and an ECS Service Instructions: Checkpoint: Scale the adoption platform monolith with an ALB and an ECS Service. ... Amazon Elastic Container Service (Amazon ECS) is a highly scalable, fast, container management service that makes it easy to run, stop, and manage Docker containers on a cluster. Likewise, if N=0 and M>0, meaning tasks are provisioning but no instances are running, then the CapacityProviderReservation = 200 and N will adjust upwards to add instances to the ASG. This is an example project on how to use AWS ECS for our applications. In this blog post, I’m going to deep dive on exactly how CAS works. Shows the help text for the specified command. Scale your service Add more tasks to scale the service $ ecs-cli compose service scale 2 INFO[0000] Updated ECS service successfully desiredCount=2 serviceName=ecscompose- service-cli-webinar INFO[0000] Describe ECS Service status desiredCount=2 runningCount=1 serviceName=ecscompose-service-cli-webinar 36. up command. Let’s think more about how M is calculated if there is at least one task in the provisioning state. Estimated reading time: 19 minutes. This command changes the desired and maximum instance count in the Auto Scaling group created by the ecs-cli up command. No scaling has been triggered yet, so all three instances are still running. We're Step 5. While this may be less efficient, it will still reach the correct size eventually. This is the same step 1 as the previous scenario. Defaults to the named profile in ~/.aws/credentials. As explained later in this blog, this metric is used by CAS to control the scaling of the ASG. Manages instance termination protection to prevent instances running non-daemon tasks from being terminated due to ASG scaling. Modifies the number of container instances in your cluster. For each group with identical resource requirements, calculate the number of instances required if a. Containerise the Mythical Mysfits monolith Lab 2. How can I do that? [ aws. But I don't know how to do it using AWS CLI. Appreciate that makes this a bit harder to debug, but it does seem clear that there are issues with the ECS CLI scale command. The next command is creating a capacity provider via the AWS CLI. Group all of the provisioning tasks so that each group has the exact same resource requirements. AWS CLI tools, available from AWS. Amazon ECS enables users schedule long-running applications, services, and … You can use this command to scale out (increase the number of The AWS-CLI is an open source tool built on top of the AWS SDK for Python (Boto) that provides commands for interacting with AWS services. Can anyone help me with this? If M > 0 and N = 0, meaning no instances, no running tasks, but at least one provisioning task, then CapacityProviderReservation = 200. In some sense, you can think of the provisioning tasks as a queue; task that can be placed due to resources get added to the queue, and as more resources become available, tasks get removed from the queue. Step 3. At this point, M = 3, N = 3, and CapacityProviderReservation = 100. Overview. All rights reserved. The third instance can be terminated without disrupting any non-daemon tasks, so M = 2. Given this assumption, if N = M, scaling out is not required, and scaling in isn’t possible. Thanks to my colleague Jay Allen for this great blog on how to use the ECS Event stream for operational tasks. - aws/copilot-cli Create the task from CLI. The digital biomarker solution code and all of its dependencies are installed in the Docker file. The Scale ECS Instances button shows up when I create the ECS cluster through the web console. When the scaling policy reduces N, it is adjusting the number of instances but it has no control over which instances actually terminate. Containerise the Mythical Mysfits monolith Lab 2. For more information about obtaining the latest version, see Installing the Amazon ECS CLI. Acknowledges that this command may create IAM resources. Apparently (as also becomes evident from the documentation), a so called task definition should encompass all of your containers that make up you stack.. i.e. The Scale ECS Instances button shows up when I create the ECS cluster through the web console. However, you might still want to know what is happening behind the scenes. However, even if it takes multiple steps, it will still eventually reach the correct size. Target tracking scaling policies manage the capacity of your ASG. No existing tasks were disrupted during this scale-in action. Scale the adoption platform monolith with an ALB and an ECS Service Lab 4. sorry we let you down. The cluster has one capacity provider, with an ASG with three instances (as shown above), all of which are running tasks. In order to scale the entire cluster automatically, each capacity provider manages the scaling of its associated ASG. Defaults to the cluster configured using With AWS Fargate, you no longer have to provision, configure, or scale clusters of virtual machines to run containers.
