Amazon ECS Container Agent

The Amazon ECS Container Agent is a component of Amazon Elastic Container Service (Amazon ECS) and is responsible for managing containers on behalf of Amazon ECS.

Usage

The best source of information on running this software is the Amazon ECS documentation.

Please note that from Agent version 1.20.0, Minimum required Docker version is 1.9.0, corresponding to Docker API version 1.21. For more information, please visit Amazon ECS Container Agent Versions.

On the Amazon Linux AMI

On the Amazon Linux AMI, we provide an installable RPM which can be used via sudo yum install ecs-init && sudo start ecs. This is the recommended way to run it in this environment.

On Other Linux AMIs

The Amazon ECS Container Agent may also be run in a Docker container on an EC2 instance with a recent Docker version installed. A Docker image is available in our Docker Hub Repository.

$ # Set up directories the agent uses
$ mkdir -p /var/log/ecs /etc/ecs /var/lib/ecs/data
$ touch /etc/ecs/ecs.config
$ # Set up necessary rules to enable IAM roles for tasks
$ sysctl -w net.ipv4.conf.all.route_localnet=1
$ iptables -t nat -A PREROUTING -p tcp -d 169.254.170.2 --dport 80 -j DNAT --to-destination 127.0.0.1:51679

On Other Linux AMIs when awsvpc networking mode is enabled

For the AWS VPC networking mode, ECS agent requires CNI plugin and dhclient to be available. ECS also needs the ecs-init to run as part of its startup. The following is an example of docker run configuration for running ecs-agent with Task ENI enabled. Note that ECS agent currently only supports cgroupfs for cgroup driver.

$ # Run the agent
$ /usr/bin/docker run --name ecs-agent \
--init \
--restart=on-failure:10 \
--volume=/var/run:/var/run \

See also the Advanced Usage section below.

On the ECS Optimized Windows AMI

ECS Optimized Windows AMI ships with a pre-installed PowerShell module called ECSTools to install, configure, and run the ECS Agent as a Windows service. To install the service, you can run the following PowerShell commands on an EC2 instance. To launch into another cluster instead of windows, replace the 'windows' in the script below with the name of your cluster.

PS C:\> Import-Module ECSTools
PS C:\> # The -EnableTaskIAMRole option is required to enable IAM roles for tasks.
PS C:\> Initialize-ECSAgent -Cluster 'windows' -EnableTaskIAMRole

Downloading Different Version of ECS Agent

To download different version of ECS Agent, you can do the following:

PS C:\> # use agentVersion = "latest" for the latest available agent version
PS C:\> $agentVersion = "v1.20.4"
PS C:\> Initialize-ECSAgent -Cluster 'windows' -EnableTaskIAMRole -Version $agentVersion

We use this to determine the source mount path for container metadata files in the case the ECS Agent is running as a container.

If enabled, the different profiles can be accessed through the agent's introspection port (e.g. curl http://localhost:51678/debug/pprof/heap > heap.pprof). In addition, agent's runtime stats are logged to /var/log/ecs/runtime-stats.log file.	false	false
ECS_EXCLUDE_IPV6_PORTBINDING	true	Determines if agent should exclude IPv6 port binding using default network mode. If enabled, IPv6 port binding will be filtered out, and the response of DescribeTasks API call will not show tasks' IPv6 port bindings, but it is still included in Task metadata endpoint.	true	true

HTTP_PROXY	10.0.0.131:3128	The hostname (or IP address) and port number of an HTTP proxy to use for the Amazon ECS agent to connect to the internet. For example, this proxy will be used if your container instances do not have external network access through an Amazon VPC internet gateway or NAT gateway or instance. If this variable is set, you must also set the NO_PROXY variable to filter Amazon EC2 instance metadata and Docker daemon traffic from the proxy.	null	null
NO_PROXY	<For Linux: 169.254.169.254,169.254.170.2,/var/run/docker.sock | For Windows: 169.254.169.254,169.254.170.2,\.\pipe\docker_engine>	The HTTP traffic that should not be forwarded to the specified HTTP_PROXY. You must specify 169.254.169.254,/var/run/docker.sock to filter Amazon EC2 instance metadata and Docker daemon traffic from the proxy.	null	null

Persistence

When you run the Amazon ECS Container Agent in production, its datadir should be persisted between runs of the Docker container. If this data is not persisted, the agent registers a new container instance ARN on each launch and is not able to update the state of tasks it previously ran.

Flags

The agent also supports the following flags:

• -k — The agent will not require valid SSL certificates for the services that it communicates with. We recommend against using this flag.
• -loglevel — Options: [<crit>|<error>|<warn>|<info>|<debug>]. The agent will output on stdout at the given level. This is overridden by the ECS_LOGLEVEL environment variable, if present.

Building and Running from Source

Running the Amazon ECS Container Agent outside of Amazon EC2 is not supported.

Docker Image (on Linux)

The Amazon ECS Container Agent may be built by typing make with the Docker daemon (v1.5.0) running.

This produces an image tagged amazon/ecs-container-agent:make that you may run as described above.

Standalone (on Linux)

The Amazon ECS Container Agent may also be run outside of a Docker container as a Go binary. This is not recommended for production on Linux, but it can be useful for development or easier integration with your local Go tools.

The following commands run the agent outside of Docker:

make gobuild
./out/amazon-ecs-agent

Make Targets (on Linux)

The following targets are available. Each may be run with make <target>.

Make Target	Description
release	(Default) Builds the agent within a Docker container and and packages it into a scratch-based image
gobuild	Runs a normal go build of the agent and stores the binary in ./out/amazon-ecs-agent
static	Runs go build to produce a static binary in ./out/amazon-ecs-agent
test	Runs all unit tests using go test
test-in-docker	Runs all tests inside a Docker container
run-integ-tests	Runs all integration tests in the engine and stats packages
clean	Removes build artifacts. Note: this does not remove Docker images

Standalone (on Windows)

The Amazon ECS Container Agent may be built by invoking scripts\build_agent.ps1

Scripts (on Windows)

The following scripts are available to help develop the Amazon ECS Container Agent on Windows:

• scripts\run-integ-tests.ps1 - Runs all integration tests in the engine and stats packages
• misc\windows-deploy\Install-ECSAgent.ps1 - Install the ECS agent as a Windows service
• misc\windows-deploy\amazon-ecs-agent.ps1 - Helper script to set up the host and run the agent as a process
• misc\windows-deploy\user-data.ps1 - Sample user-data that can be used with the Windows Server 2016 with Containers AMI to run the agent as a process
