to your account. ECS. Use a specific profile from your credential file. See the Getting started guide in the AWS CLI User Guide for more information. To list instances from your Auto Scaling group that don't have scale-in protection enabled, run the following AWS CLI command using the query feature: Then, follow these steps to enable scale-in protection for the specified instances in your Auto Scaling group: 2. The AWS::ECS::CapacityProvider resource creates an Amazon Elastic Container Service ( Amazon ECS) capacity provider. Pagination continues from the end of the previous results that returned the nextToken value. I can see the CloudWatch alarm that has been active during that period. The scale in process is not affected by this parameter. First time using the AWS CLI? Note: If you receive errors when running AWS CLI commands, make sure that youre using the most recent version of the AWS CLI. To use the following examples, you must have the AWS CLI installed and configured. The following describe-capacity-providers example retrieves details about a specific capacity provider. If you have no provisioning tasks, then M=the number of instances running at least one non-daemon service task. AWS services or capabilities described in AWS Documentation may vary by region/location. Now you will see that this provider has been successfully created. @tekaeren You can watch the Re:invent session with a demo that covers scaling out from zero: https://youtu.be/v9xuKAdShFw. The following describe-capacity-providers example retrieves details about all capacity providers. Capacity Provider Auto Scaling Group Provider Args. For example, if you set it to 80%, you will have 20% extra idle capacity available,saving you the time of allocating and setting up a new container instance. The managed termination protection setting to use for the Auto Scaling group capacity provider. The capacity provider can't be deleted. This can be a temporary secret key if the corresponding session token is supplied to the -SessionToken parameter. Is the AmazonECSManaged tag applied by the capacity provider? One part of a key-value pair that make up a tag. Determines whether to use managed scaling for the capacity provider. Now adding new capacity provider results with capacity metric that jumps from 0 to 100 every ten-something minutes and then drops to 0 when connected ASG starts it's instances. Managed termination protection: Enabled. ', manually triggering ASG associated with capacity provider -> capacity provider metric drops to 0, task does not see any change, and does not start any containers even the capacity exists, after the 15minuter, capacity provider alarm triggers ASG to scale down, capacity provider metric returns to 100, task still in limbo. Only capacity providers using an Auto Scaling group can be created. This parameter is not required if the user's default network identity can or should be used during authentication. To enable managed termination protection for a capacity provider, the Auto Scaling group must have instance protection from scale in enabled. I also had similar problems and they magically self-resolved ;). If so what are they? The JSON string follows the format provided by --generate-cli-skeleton. The AWS access key for the user account. --generate-cli-skeleton (string) In this walkthrough, we will run an ECS service for a stateless web application on both On-Demand and Spot Instances using two capacity providers connected to two Auto Scaling groups. One best practice of using Spot Instances is tobe flexible with instance types. If the target is set to 90, i am always left with spare capacity causing 1 or 2 machines to span up. When I try to create a cluster capacity provider in Amazon Elastic Container Service (Amazon ECS), I get the following error: "The managed termination protection setting for the capacity provider is invalid. the ability to edit the warm-up time should be coming soon as part of the ability to update capacity provider parameters. hi @kgyovai those tags are causing an issue? 3. task instances set to 0, capacity provider instances 0 -> the capacity provider metric stays at 100, task instances set to 4, capacity provider instances 0 -> capacity provider metric stays at 100, in task instances 'events' I see" 'service [service_name] was unable to place a task because no container instance met all of its requirements. Have you enabled scaled in protection on ASG. Use attribute-based instance type selection to select all the instance types that match the requirements (24 vCPU, 48 GiB of memory), and look in the current instance type generations. It's completely not clear (at least to me) how value of capacity metric is calculated. Problem 1: you need to have "Protect from Scale in" on in ASG first before associating this ASG with ECS Capacity. ECS cluster; Fargate capacity providers The Amazon Resource Name (ARN) of the failed resource. If TAGS is specified, the tags are included in the response. Terraform module which creates ECS (Elastic Container Service) resources on AWS. The name of the capacity provider to update. The update status reason. You define them. Problem 1: you need to have "Protect from Scale in" on in ASG first before associating this ASG with ECS Capacity. Is there any instance on the ASG running with scale-in protection disabled ? When managed termination protection is enabled, Amazon ECS prevents the Amazon EC2 instances in an Auto Scaling group that contain tasks from being terminated during a scale-in action. To preview matching instance types, use this command and update excluded instance types accordingly: Once youre happy with the matched instance types, make sure to update the instance requirements in the following command. --cli-input-json (string) If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The scale in process is not affected by this parameter If this parameter is omitted, the default value of. To enable managed termination protection for a capacity provider, the Auto Scaling group must have instance protection from scale in enabled.". This value does not appear to be editable. I have target_capacity = 100 so when there are 0 tasks the instance count is also 0. scale out so the 2 desired tasks can be placed). i would do that and then include this in your user-data when you spawn the instance #!/bin/bash echo ECS_CLUSTER=your-cluster-name >> /etc/ecs/ecs.config if you ssh onto the box, you should be able to see it register with the cluster then in the ecs agent docker logs. AWS CLI version 2, the latest major version of AWS CLI, is now stable and recommended for general use. The desired number of tasks for this service is 10, the strategybase has been set to 2, and the weight has been set to 1:1for Spot and On-Demand Instances. When managed termination protection is enabled, Amazon ECS prevents the Amazon EC2 instances in an Auto Scaling group that contain tasks from being terminated during a scale-in action. here. @coultn Thanks for the explanation. I have applied the required change for that. From what I read here ECS capacity providers should (generally) prevent tasks immediately failing on resource limits by putting them in a "Provisioning" state and spinning up a new EC2 instance. If the value is set to 0, the socket connect will be blocking and not timeout. This configuration is used for Amazon ECS cluster auto scaling. Can you confirm that if you enable scale-in protection at the time of ASG creation, scale-in of the instances through capacity provider/cluster auto scaling works fine in that case? As mentioned here the service should use Capacity provider strategy in order to show provisioning instead of insufficient capacity. The target capacity for the capacity provider assigned to my cluster is set to 100 (this is a percentage; not a number of instances - which is not made clear in the API docs) as shown below. Special cases: Use the -Select parameter to control the cmdlet output. The first Auto Scaling group runs with 100% On-Demand Instances. AWS compute, storage, database, and other services run locally on Outposts, and you can access the full range of AWS services available in the . If the value is set to 0, the socket read will be blocking and not timeout. #653 (comment). Tip: Use this command to list subnets in your AWS account in the current region: Now that the Auto Scaling groups have been created, create two capacity providers and associate them with the two Auto Scaling groups: Before moving to the next step, verify the two capacity providers have been created successfully: Run the following command to create a new ECS cluster, associate the capacity providers with it, and add a default capacity provider strategy to it: If you create new ECS services and tasks that dont specify a custom strategy, they will be running on On-Demand capacity by default. The ASG desired capacity doesn't reflect the number of actual ECS instances that the capacity provider is managing. On the Instance management tab, choose Actions, Set scale-in protection. This governs the endpoint that will be used when calling service operations. For EC2 based container instances, a capacity provider consists of a name, an Auto Scaling group (ASG), and settings for managed scaling and managed termination protection. @kgyovai Are you using a capacity provider strategy with the service? Only capacity providers using an Auto Scaling group can be created. The capacity provider is in the process of being deleted. It is very useful to confront with what I see. An attribute to define Managed termination protection. Performs service operation based on the JSON string provided. If you set a target capacity to less than 100%, you are requesting to have spare capacity in your cluster. However, I've set the Termination protection on the ASG properly. - An ASG associated to an EC2 Capacity Provider (managed scaling + managed termination protection active) - Two Auto Scaling policy (one in each of the service), with the same tracked metric but different min/max . If all the container instances use capacity provider managed termination protection, Amazon ECS removes the scale-in protection on the container instances that do not have non-daemon tasks running. Service tasks on the container instance that are in the RUNNING state are stopped and replaced according to the services deployment configuration parameters, minimum healthy percent and maximum percent. Prints a JSON skeleton to standard output without sending an API request. Contribute to bardsleysdgr/terra-utilities development by creating an account on GitHub. For Amazon ECS on Amazon EC2 users, a capacity provider consists of a capacity provider name, an Auto Scaling group, and the settings for managed scaling and managed termination protection. This determines whether the Auto Scaling group has managed termination protection. --capacity-providers (list) The short name or full Amazon Resource Name (ARN) of one or more capacity providers. You define both. (string) Syntax: "string" "string" . this. Inputs. Unless otherwise stated, all examples have unix-like quotation rules. Choose the Capacity Providers tab. The Auto Scaling group and each instance in the Auto Scaling group must have instance protection from scale-in actions enabled as well. Hi @kgyovai and @venu-ibex-9 Capacity providers are associated with an Amazon ECS cluster and are used in capacity provider strategies to facilitate cluster auto scaling. The current status of the capacity provider. We recently announced a new feature calledattribute-based instance type selection (ABS). If you use launch type, the tasks will NOT go to provisioning and you will see the error you are seeing. Used with SAML-based authentication when ProfileName references a SAML role profile. The scale in process is not affected by this parameter If this parameter is omitted, the default value of 1 is used. You can reach him on twitter @JP_Alawala, Click here to return to Amazon Web Services homepage, attribute-based instance type selection (ABS), An IAM instance role to allow the EC2 instances to communicate with the ECS clusterFollow this. There is no Capacity provider assigned to the ECS cluster. @coultn See below for the tags that are applied to the ASG. Tasks CPU and memory are almost equal or equal to the instance size max values, so no more than 1 task can be placed on an instance. A. Hi @MikeKroell can you confirm that you are indeed using a capacity provider strategy when using the runTask API? Managed Termination Protection AutoScalinggroup Amazon ECS ECS CP Spot Instances are a great fit for containersbecause both are designed to be interruptible and replaceable. Amazon.PowerShell.Cmdlets.ECS.AmazonECSClientCmdlet.ClientConfig. ECS cluster is stable, all tasks started and deployed to dedicated ECS instances. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Initial Autoscaling Group Configuration (prior to manually adjusting desired capacity), The ASG has a minimum and maximum size that will not be exceeded (however, you can change these values), Your account has limits on how many instances of each type can be running at one time, In some cases, you may get an insufficient capacity error (ICE) if EC2 is unable to fulfill your request for more instances, If you are using Spot instances, the current Spot price may exceed the maximum price set for the instances you are requesting, the terraform documentation is not clean with respect to the recent capacity provider settings. The following basic restrictions apply to tags: The metadata that you apply to a resource to help you categorize and organize them. Click here to return to Amazon Web Services homepage, make sure that youre using the most recent version of the AWS CLI. Under Instance scale-in protection, select Enable instance scale-in protection. Having ECS cluster with default provider set to the same one as the service's capacity provider strategy (weight 100) and capacity provider set to 100, what I see is: During the time, when there was capacity available I've tried to force task deploy, and even add another service associated with the capacity provider, neither action did provide working container. We have an ecs cluster with a managed auto scaling group (aws_ecs_capacity_provider) and a aws_launch_template to create EC2 instances we manually turned off the scale in protection in the advanced settiongs of the ASG. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value. If the ECS agent detects an interruption notification at the Instance Metadata Service, it sets the instance state to DRAININGto prevent new tasks from being scheduled for placement on this container instance. We will be publishing a deep dive blog that covers how the metric is calculated, but the simple version of it is that CapacityProviderReservation = M/N x 100, where N = the number of instances already in your ASG, and M = the estimated number of instances required to run all existing and provisioning tasks. Hi, i m with terraform 0.11, for a project i need to deploy differents capacity_providers to a ecs clusters wich is alreated create and can't be It seems that the capacity provider will only mark a task as "provisioning" if there are candidate ECS instances in the cluster. Inputs. If this field is omitted, tags aren't included in the response. Use the following command to verify the UserDataattribute in the launch template you just created: Its a Base64-encoded string that should include the following configurations: #!/bin/bash echo "ECS_CLUSTER=ecs-webapp" >> /etc/ecs/ecs.config echo "ECS_BACKEND_HOST=" >> /etc/ecs/ecs.config echo "ECS_ENABLE_SPOT_INSTANCE_DRAINING=true" >>/etc/ecs/ecs.config echo "ECS_CONTAINER_STOP_TIMEOUT=90s" >> /etc/ecs/ecs.config. Do On-Demand Instances get deployed instead? The short answer is, no, it doesnt happen automatically. What is the relationship between the desired capacity of the ASG and the "desired size" of the capacity provider? The following is the CapacityProviderReservation metric that never goes above 200% when the initial 2 instances start. Maximum key length - 128 Unicode characters in UTF-8, Maximum value length - 256 Unicode characters in UTF-8. No instance with scale-in protection disabled running. I have an ECS cluster backed by EC2 machines in an autoscaling group. As a second best practice, if your workload requires a faster scaling out and you have enabled managed scaling, you can over-provision capacity by setting target capacityin a capacity provider to be less than 100%. Open the Amazon EC2 console, and then choose Auto Scaling Groups from the navigation pane. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.ECS.Model.UpdateCapacityProviderResponse). AWS Outposts is a fully managed service that offers the same AWS infrastructure, AWS services, APIs, and tools to virtually any data center, co-location space, or on-premises facility, in the form of a physical rack connected to the AWS global network. You can also mix Spot and On-Demand capacity within the same ECS service, which we will demonstrate next. The default value is 'CapacityProvider'. When additional capacity is required, Amazon ECS will scale up the minimum scaling step size even if the actual demand is less than the minimum scaling step size. Warning When using managed termination protection, managed scaling must also be used otherwise managed termination protection doesn't work. Up to 100 capacity providers can be described in an action. From the Instance ID column, select the instances to apply scale-in protection to. Replace yourASGName with the name of your Auto Scaling group. Did you find this page useful? If you will not be using AWS CloudShell, install the jq tool following this guide. Lots of tasks fail to start due to going above 30 min limit in the provisioning state. Provides an ECS cluster capacity provider.
