This is an example of a script that will build a Grouper Docker container based on the TIER container. If the build is successful, it will push the new image to a private AWS Elastic Container Registry (ECR). In this case, the build host runs with an IAM role that with an IAM policy attached to it that allows it access to push to this repo. This script could be modified to run as part of a Jenkins pipeline.

The following is a Dockerfile that is used by the above build script that layers in the necessary local configurations for running Grouper needed by the Internet2 Collaboration Platform that houses spaces.internet2.edu. The files that contain secrets are located in an encrypted S3 bucket and the build host runs with an IAM role that allows it to access this bucket. This example is for a Grouper UI container.

The following is an example Elastic Container Service (ECS) task definition for running this container. Configuration such as log groups for Cloudwatch, the port to direct traffic from the Elastic Load Balancer (ELB), the memory requirements for the container, as well as the ECR location to pull the container from. Note the "command" value, as this instructs the container as what component to act as. In this case, it is going to run as a Grouper UI. Alternately, the command could be "loader" (to run as a Grouper Loader), or "ws" (to run as a Grouper Web Services container). This task definition is part of an overall Cloudformation template that builds out the environment that houses other TIER containers used by the Internet2 Collaboration Platform.

The following is an apache configuration for running the Grouper container in ECS. Since containers have to sit behind load balancers, the remote IP address is that of the load balancer. However, the load balancer inserts a header (X-Forwarded-For) that contains the IP address of the actual client, so that is logged. Rather than having the httpd listen on 2 ports, if the request comes in as http (as seen in the X-Forwarded-Proto), it will redirect to https.
