Terraform module to create an ECS Service for a web app (task), and an ALB target group to route requests.
This project is part of our comprehensive "SweetOps" approach towards DevOps.
It's 100% Open Source and licensed under the APACHE2.
We literally have hundreds of terraform modules that are Open Source and well-maintained. Check them out!
IMPORTANT: The master
branch is used in source
just as an example. In your code, do not pin to master
because there may be breaking changes between releases.
Instead pin to the release tag (e.g. ?ref=tags/x.y.z
) of one of our latest releases.

}
The container_image
in the container_definition
module is the Docker image used to start a container.
This string is passed directly to the Docker daemon. Images in the Docker Hub registry are available by default.
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 Create a container section of the Docker Remote API 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 are not 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
).
