ContainerOverride

Structure Class

ContainerOverride dataclass

Bases: _SerdeShape

The overrides that are sent to a container. An empty container override can be passed in. An example of an empty container override is {"containerOverrides": [ ] }. If a non-empty container override is specified, the name parameter must be included.

You can use Secrets Manager or Amazon Web Services Systems Manager Parameter Store to store the sensitive data. For more information, see Retrieve secrets through environment variables in the Amazon ECS Developer Guide.
