Amazon ECS Agent - Functional Tests

This directory contains scripts to perform a functional test of a build of the agent against the production Amazon EC2 Container Service.

These tests are meant to cover scenarios that are difficult to cover with go test. The bulk of the tests in this repository may be found alongside the Go source code.

These tests are meant to be run on an EC2 instance with a suitably powerful role to interact with ECS. You may be charged for the AWS resources utilized while running these tests. It is not recommended to run these without understanding the implications of doing so and it is certainly not recommended to run them on an AWS account handling production work-loads.

Setup

Before running these tests, you should build the ECS Agent and tag its image as amazon/amazon-ecs-agent:make.

You should also run the registry the tests pull from. This can most easily be done via make test-registry.

Running

These tests should be run on an EC2 instance able to correctly run the ECS agent and access the ECS APIs.

The best way to run them is via the make run-functional-tests target.

Thay may also be manually run with go test -tags functional -v ./...,

Envrionment Variable

In order to run Telemetry functional test in non Amazon Linux AMI environment, the following environment variables should be set:

  • CGROUP_PATH: cgroup path on the host, default value "/cgroup"
  • EXECDRIVER_PATH: execdriver path on the host, default value "/var/run/docker/execdriver" In order to run TaskIamRole functional test, the following steps should be done first:
  • Run command: sysctl -w net.ipv4.conf.all.route_localnet=1 and iptables -t nat -A PREROUTING -p tcp -d 169.254.170.2 --dport 80 -j DNAT --to-destination 127.0.0.1:51679.
  • Set the environment variable to enable the test: export TEST_TASK_IAM_ROLE=true.
  • Set the envrionment variable of IAM roles the test will use: export TASK_IAM_ROLE_ARN="iam role arn", the role should have the ec2:DescribeRegions permission and have the trust relationship with "ecs-tasks.amazonaws.com". Or if the TASK_IAM_ROLE_ARN isn't set, it will use the IAM role attached to the instance profile. In this case, except the permissions required before, the IAM role should also have iam:GetInstanceProfile permission.
