You can now use the Docker shm-size and tmpfs parameters in Amazon Elastic Container Service (Amazon ECS) task definitions.

The shm-size parameter allows you to specify the shared memory that a container can use. It enables memory-intensive containers to run faster by giving more access to allocated memory.

The tmpfs parameter allows you to mount a temporary volume in memory. This removes the need to store data in your container instance and allows containers to run in a read-only mode, which can improve the security of your service.

For more information about using Docker parameters in task definitions, visit the Amazon ECS documentation.

Amazon ECS is available in US East (N. Virginia), US East (Ohio), US West (Oregon), US West (N. California), Canada (Central), South America (São Paulo), GovCloud (US), EU (Ireland), EU (Frankfurt), EU (London), EU(Paris), Asia Pacific (Singapore), Asia Pacific (Tokyo), Asia Pacific (Sydney), Asia Pacific (Seoul), Asia Pacific (Mumbai), and China (Beijing) regions.
