Description

Amazon EC2 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 of Amazon EC2 instances. Amazon ECS lets you launch and stop container-enabled applications with simple API calls, allows you to get the state of your cluster from a centralized service, and gives you access to many familiar Amazon EC2 features like security groups, Amazon EBS volumes, and IAM roles.

You can use Amazon ECS to schedule the placement of containers across your cluster based on your resource needs, isolation policies, and availability requirements. Amazon EC2 Container Service eliminates the need for you to operate your own cluster management and configuration management systems or worry about scaling your management infrastructure.

Errors

Error matchers are designed for use with the functions provided by Control.Exception.Lens. This allows catching (and rethrowing) service specific errors returned by ECS.

InvalidParameterException

_InvalidParameterException :: AsError a => Getting (First ServiceError) a ServiceError Source

The specified parameter is invalid. Review the available parameters for the API request.

ServerException

_ServerException :: AsError a => Getting (First ServiceError) a ServiceError Source

These errors are usually caused by a server-side issue.

ClusterContainsServicesException

_ClusterContainsServicesException :: AsError a => Getting (First ServiceError) a ServiceError Source

You cannot delete a cluster that contains services. You must first update the service to reduce its desired task count to 0 and then delete the service. For more information, see UpdateService and DeleteService.

ClusterContainsContainerInstancesException

_ClusterContainsContainerInstancesException :: AsError a => Getting (First ServiceError) a ServiceError Source

You cannot delete a cluster that has registered container instances. You must first deregister the container instances before you can delete the cluster. For more information, see DeregisterContainerInstance.

ServiceNotActiveException

_ServiceNotActiveException :: AsError a => Getting (First ServiceError) a ServiceError Source

The specified service is not active. You cannot update a service that is not active. If you have previously deleted a service, you can recreate it with CreateService.

NoUpdateAvailableException

_NoUpdateAvailableException :: AsError a => Getting (First ServiceError) a ServiceError Source

There is no update available for this Amazon ECS container agent. This could be because the agent is already running the latest version, or it is so old that there is no update path to the current version.

ClusterNotFoundException

_ClusterNotFoundException :: AsError a => Getting (First ServiceError) a ServiceError Source

The specified cluster could not be found. You can view your available clusters with ListClusters. Amazon ECS clusters are region-specific.

ServiceNotFoundException

_ServiceNotFoundException :: AsError a => Getting (First ServiceError) a ServiceError Source

The specified service could not be found. You can view your available services with ListServices. Amazon ECS services are cluster-specific and region-specific.

MissingVersionException

_MissingVersionException :: AsError a => Getting (First ServiceError) a ServiceError Source

Amazon ECS is unable to determine the current version of the Amazon ECS container agent on the container instance and does not have enough information to proceed with an update. This could be because the agent running on the container instance is an older or custom version that does not use our version information.

UpdateInProgressException

_UpdateInProgressException :: AsError a => Getting (First ServiceError) a ServiceError Source

There is already a current Amazon ECS container agent update in progress on the specified container instance. If the container agent becomes disconnected while it is in a transitional stage, such as PENDING or STAGING, the update process can get stuck in that state. However, when the agent reconnects, it will resume where it stopped previously.

ClientException

_ClientException :: AsError a => Getting (First ServiceError) a ServiceError Source

These errors are usually caused by something the client did, such as use an action or resource on behalf of a user that doesn't have permission to use the action or resource, or specify an identifier that is not valid.

Waiters

Waiters poll by repeatedly sending a request until some remote success condition configured by the Wait specification is fulfilled. The Wait specification determines how many attempts should be made, in addition to delay and retry strategies.

ServicesInactive

servicesInactive :: Wait DescribeServices Source

Polls DescribeServices every 15 seconds until a successful state is reached. An error is returned after 40 failed checks.

TasksRunning

tasksRunning :: Wait DescribeTasks Source

Polls DescribeTasks every 6 seconds until a successful state is reached. An error is returned after 100 failed checks.

TasksStopped

tasksStopped :: Wait DescribeTasks Source

Polls DescribeTasks every 6 seconds until a successful state is reached. An error is returned after 100 failed checks.

Operations

Some AWS operations return results that are incomplete and require subsequent requests in order to obtain the entire result set. The process of sending subsequent requests to continue where a previous request left off is called pagination. For example, the ListObjects operation of Amazon S3 returns up to 1000 objects at a time, and you must send subsequent requests with the appropriate Marker in order to retrieve the next page of results.

Operations that have an AWSPager instance can transparently perform subsequent requests, correctly setting Markers and other request facets to iterate through the entire result set of a truncated API operation. Operations which support this have an additional note in the documentation.

Many operations have the ability to filter results on the server side. See the individual operation parameters for details.

Cluster

data Cluster Source

A regional grouping of one or more container instances on which you can run task requests. Each account receives a default cluster the first time you use the Amazon ECS service, but you may also create other clusters. Clusters may contain more than one instance type simultaneously.

See: cluster smart constructor.

Instances

cluster :: Cluster Source

Creates a value of Cluster with the minimum fields required to make a request.

Use one of the following lenses to modify other fields as desired:

cStatus :: Lens' Cluster (Maybe Text) Source

The status of the cluster. The valid values are ACTIVE or INACTIVE. ACTIVE indicates that you can register container instances with the cluster and the associated instances can accept tasks.

cClusterARN :: Lens' Cluster (Maybe Text) Source

The Amazon Resource Name (ARN) that identifies the cluster. The ARN contains the 'arn:aws:ecs' namespace, followed by the region of the cluster, the AWS account ID of the cluster owner, the cluster namespace, and then the cluster name. For example, arn:aws:ecs:region:012345678910:cluster/test.

cRunningTasksCount :: Lens' Cluster (Maybe Int) Source

The number of tasks in the cluster that are in the RUNNING state.

cRegisteredContainerInstancesCount :: Lens' Cluster (Maybe Int) Source

The number of container instances registered into the cluster.

cPendingTasksCount :: Lens' Cluster (Maybe Int) Source

The number of tasks in the cluster that are in the PENDING state.

cClusterName :: Lens' Cluster (Maybe Text) Source

A user-generated string that you can use to identify your cluster.

cActiveServicesCount :: Lens' Cluster (Maybe Int) Source

The number of services that are running on the cluster in an ACTIVE state. You can view these services with ListServices.

Container

data Container Source

A docker container that is part of a task.

See: container smart constructor.

Instances

container :: Container Source

Creates a value of Container with the minimum fields required to make a request.

Use one of the following lenses to modify other fields as desired:

cNetworkBindings :: Lens' Container [NetworkBinding] Source

The network bindings associated with the container.

cContainerARN :: Lens' Container (Maybe Text) Source

cLastStatus :: Lens' Container (Maybe Text) Source

The last known status of the container.

cReason :: Lens' Container (Maybe Text) Source

A short (255 max characters) human-readable string to provide additional detail about a running or stopped container.

cName :: Lens' Container (Maybe Text) Source

The name of the container.

cExitCode :: Lens' Container (Maybe Int) Source

The exit code returned from the container.

ContainerDefinition

data ContainerDefinition Source

Container definitions are used in task definitions to describe the different containers that are launched as part of a task.

See: containerDefinition smart constructor.

Instances

containerDefinition :: ContainerDefinition Source

Creates a value of ContainerDefinition with the minimum fields required to make a request.

Use one of the following lenses to modify other fields as desired:

cdImage :: Lens' ContainerDefinition (Maybe Text) Source

The image used to start a container. This string is passed directly to the Docker daemon. Images in the Docker Hub registry are available by default. Other repositories are specified with 'repository-url\/image:tag'.

cdCommand :: Lens' ContainerDefinition [Text] Source

The CMD that is passed to the container. For more information on the Docker CMD parameter, see https://docs.docker.com/reference/builder/#cmd.

cdVolumesFrom :: Lens' ContainerDefinition [VolumeFrom] Source

Data volumes to mount from another container.

cdEnvironment :: Lens' ContainerDefinition [KeyValuePair] Source

The environment variables to pass to a container.

cdEntryPoint :: Lens' ContainerDefinition [Text] Source

Early versions of the Amazon ECS container agent do not properly handle entryPoint parameters. If you have problems using entryPoint, update your container agent or enter your commands and arguments as command array items instead.

The ENTRYPOINT that is passed to the container. For more information on the Docker ENTRYPOINT parameter, see https://docs.docker.com/reference/builder/#entrypoint.

cdPortMappings :: Lens' ContainerDefinition [PortMapping] Source

The list of port mappings for the container.

cdMemory :: Lens' ContainerDefinition (Maybe Int) Source

The number of MiB of memory reserved for the container. If your container attempts to exceed the memory allocated here, the container is killed.

cdName :: Lens' ContainerDefinition (Maybe Text) Source

The name of a container. If you are linking multiple containers together in a task definition, the name of one container can be entered in the links of another container to connect the containers.

cdMountPoints :: Lens' ContainerDefinition [MountPoint] Source

The mount points for data volumes in your container.

cdLinks :: Lens' ContainerDefinition [Text] Source

The link parameter allows containers to communicate with each other without the need for port mappings, using the name parameter. The 'name:internalName' construct is analogous to 'name:alias' in Docker links. For more information on linking Docker containers, see https://docs.docker.com/userguide/dockerlinks/.

Containers that are collocated on a single container instance may be able to communicate with each other without requiring links or host port mappings. Network isolation is achieved on the container instance using security groups and VPC settings.

cdEssential :: Lens' ContainerDefinition (Maybe Bool) Source

If the essential parameter of a container is marked as true, the failure of that container will stop the task. If the essential parameter of a container is marked as false, then its failure will not affect the rest of the containers in a task. If this parameter is omitted, a container is assumed to be essential.

All tasks must have at least one essential container.

cdCpu :: Lens' ContainerDefinition (Maybe Int) Source

The number of cpu units reserved for the container. A container instance has 1,024 cpu units for every CPU core. This parameter specifies the minimum amount of CPU to reserve for a container, and containers share unallocated CPU units with other containers on the instance with the same ratio as their allocated amount.

For example, if you run a single-container task on a single-core instance type with 512 CPU units specified for that container, and that is the only task running on the container instance, that container could use the full 1,024 CPU unit share at any given time. However, if you launched another copy of the same task on that container instance, each task would be guaranteed a minimum of 512 CPU units when needed, and each container could float to higher CPU usage if the other container was not using it, but if both tasks were 100% active all of the time, they would be limited to 512 CPU units.

The Docker daemon on the container instance uses the CPU value to calculate the relative CPU share ratios for running containers. For more information, see CPU share constraint in the Docker documentation. The minimum valid CPU share value that the Linux kernel will allow is 2; however, the CPU parameter is not required, and you can use CPU values below 2 in your container definitions. For CPU values below 2 (including null), the behavior varies based on your Amazon ECS container agent version:

  • Agent versions less than or equal to 1.1.0: Null and zero CPU values are passed to Docker as 0, which Docker then converts to 1,024 CPU shares. CPU values of 1 are passed to Docker as 1, which the Linux kernel converts to 2 CPU shares.
  • Agent versions greater than or equal to 1.2.0: Null, zero, and CPU values of 1 are passed to Docker as 2.

The port number on the container instance to reserve for your container. You can specify a non-reserved host port for your container port mapping, or you can omit the hostPort (or set it to '0') while specifying a containerPort and your container will automatically receive a port in the ephemeral port range for your container instance operating system and Docker version.

The default ephemeral port range is 49153 to 65535, and this range is used for Docker versions prior to 1.6.0. For Docker version 1.6.0 and later, the Docker daemon tries to read the ephemeral port range from '\/proc\/sys\/net\/ipv4\/ip_local_port_range'; if this kernel parameter is unavailable, the default ephemeral port range is used. You should not attempt to specify a host port in the ephemeral port range, since these are reserved for automatic assignment. In general, ports below 32768 are outside of the ephemeral port range.

The default reserved ports are 22 for SSH, the Docker ports 2375 and 2376, and the Amazon ECS Container Agent port 51678. Any host port that was previously specified in a running task is also reserved while the task is running (once a task stops, the host port is released).The current reserved ports are displayed in the remainingResources of DescribeContainerInstances output, and a container instance may have up to 50 reserved ports at a time, including the default reserved ports (automatically assigned ports do not count toward this limit).

pmContainerPort :: Lens' PortMapping (Maybe Int) Source

The port number on the container that is bound to the user-specified or automatically assigned host port. If you specify a container port and not a host port, your container will automatically receive a host port in the ephemeral port range (for more information, see hostPort).
