image

The image used to start a container. This string is passed directly to the Docker daemon. By default, images in the Docker Hub registry are available. Other repositories are specified with either `repository-url/image:tag` or `repository-url/image@digest`. Up to 255 letters (uppercase and lowercase), numbers, hyphens, underscores, colons, periods, forward slashes, and number signs are allowed. This parameter maps to `Image` in the docker container create command and the `IMAGE` parameter of docker run.

• When a new task starts, the Amazon ECS container agent pulls the latest version of the specified image and tag for the container to use. However, subsequent updates to a repository image aren't propagated to already running tasks.

• Images in Amazon ECR repositories can be specified by either using the full `registry/repository:tag` or `registry/repository@digest`. For example, `012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>:latest` or `012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>@sha256:94afd1f2e64d908bc90dbca0035a5b567EXAMPLE`.

• Images in official repositories on Docker Hub use a single name (for example, `ubuntu` or `mongo`).

• Images in other repositories on Docker Hub are qualified with an organization name (for example, `amazon/amazon-ecs-agent`).

• Images in other online repositories are qualified further by a domain name (for example, `quay.io/assemblyline/ubuntu`).
