Updates the Amazon ECS container agent on a specified container instance. Updating the Amazon ECS container agent does not interrupt running tasks or services on the container instance. The process for updating the agent differs depending on whether your container instance was launched with the Amazon ECS-optimized AMI or another operating system.

UpdateContainerAgent requires the Amazon ECS-optimized AMI or Amazon Linux with the ecs-init service installed and running. For help updating the Amazon ECS container agent on other operating systems, see Manually Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide.


For .NET Core and PCL this operation is only available in asynchronous form. Please refer to UpdateContainerAgentAsync.

ClientException These errors are usually caused by a client action, such as using an action or resource on behalf of a user that doesn't have permissions to use the action or resource, or specifying an identifier that is not valid.
ClusterNotFoundException The specified cluster could not be found. You can view your available clusters with ListClusters. Amazon ECS clusters are region-specific.
InvalidParameterException The specified parameter is invalid. Review the available parameters for the API request.
MissingVersionException 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.
NoUpdateAvailableException 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.
ServerException These errors are usually caused by a server issue.
UpdateInProgressException 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 resumes where it stopped previously.
