The volume is mounted read-only as /usr/share/nginx/html on the web container, and read-write as /nginx/ on the timer container. You can define multiple containers and data volumes in a single task definition. If the network mode is awsvpc , the task is allocated an elastic network interface, and you must specify a NetworkConfiguration value when you create a service or run a task with the task definition. Fun fact: a task is very similar to a Kubernetes ‘pod’.

If the swappiness parameter is not specified, a default value of 60 is used. We do not recommend using plaintext environment variables for sensitive information, such as credential data. Images in official repositories on Docker Hub use a single name (for example. The full Amazon Resource Name (ARN) of the task definition. Each tag consists of a key and an optional value, both of which you define. When you specify an IAM role for a task, its containers can then use the latest versions of the AWS CLI or SDKs to make API requests to the AWS services that are specified in the IAM policy associated with the role.

Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type). This configuration would allow the container to only reserve 128 MiB of memory from the remaining resources on the container instance, but also allow the container to consume more memory resources when needed. Automatically assigned ports don't count toward the 100 reserved ports limit. The time period in seconds to wait for a health check to succeed before it is considered a failure. The driver value must match the driver name provided by Docker because it is used for task placement. If the essential parameter of a container is marked as false , then its failure does not affect the rest of the containers in a task. The number of GPUs reserved for all containers in a task should not exceed the number of available GPUs on the container instance the task is launched on. In general, ports below 32768 are outside of the ephemeral port range. String values are converted to an integer indicating the CPU units when the task definition is registered.
