Using an HTTP proxy for Amazon ECS Linux container instances

You can configure your Amazon ECS container instances to use an HTTP proxy for both the Amazon ECS container agent and the Docker daemon. This is useful if your container instances do not have external network access through an Amazon VPC internet gateway, NAT gateway, or instance.

To configure your Amazon ECS Linux container instance to use an HTTP proxy, set the following variables in the relevant files at launch time (with Amazon EC2 user data). You can also manually edit the configuration file, and then restart the agent.

/etc/ecs/ecs.config (Amazon Linux 2 and AmazonLinux AMI)
HTTP_PROXY=10.0.0.131:3128

Set this value to 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, your container instances may not have external network access through an Amazon VPC internet gateway, NAT gateway, or instance.

NO_PROXY=169.254.169.254,169.254.170.2,/var/run/docker.sock

Set this value to 169.254.169.254,169.254.170.2,/var/run/docker.sock to filter EC2 instance metadata, IAM roles for tasks, and Docker daemon traffic from the proxy.

/etc/systemd/system/ecs.service.d/http-proxy.conf (Amazon Linux 2 only)
Environment="HTTP_PROXY=10.0.0.131:3128/"

Set this value to the hostname (or IP address) and port number of an HTTP proxy to use for ecs-init to connect to the internet. For example, your container instances may not have external network access through an Amazon VPC internet gateway, NAT gateway, or instance.

Environment="NO_PROXY=169.254.169.254,169.254.170.2,/var/run/docker.sock"

Set this value to 169.254.169.254,169.254.170.2,/var/run/docker.sock to filter EC2 instance metadata, IAM roles for tasks, and Docker daemon traffic from the proxy.

/etc/init/ecs.override (Amazon Linux AMI only)
env HTTP_PROXY=10.0.0.131:3128

Set this value to the hostname (or IP address) and port number of an HTTP proxy to use for ecs-init to connect to the internet. For example, your container instances may not have external network access through an Amazon VPC internet gateway, NAT gateway, or instance.

env NO_PROXY=169.254.169.254,169.254.170.2,/var/run/docker.sock

Set this value to 169.254.169.254,169.254.170.2,/var/run/docker.sock to filter EC2 instance metadata, IAM roles for tasks, and Docker daemon traffic from the proxy.

/etc/systemd/system/docker.service.d/http-proxy.conf (Amazon Linux 2 only)
Environment="HTTP_PROXY=http://10.0.0.131:3128"

Set this value to the hostname (or IP address) and port number of an HTTP proxy to use for the Docker daemon to connect to the internet. For example, your container instances may not have external network access through an Amazon VPC internet gateway, NAT gateway, or instance.

Environment="NO_PROXY=169.254.169.254"

Set this value to 169.254.169.254 to filter EC2 instance metadata from the proxy.

/etc/sysconfig/docker (Amazon Linux AMI and Amazon Linux 2 only)
export HTTP_PROXY=http://10.0.0.131:3128

Set this value to the hostname (or IP address) and port number of an HTTP proxy to use for the Docker daemon to connect to the internet. For example, your container instances may not have external network access through an Amazon VPC internet gateway, NAT gateway, or instance.

export NO_PROXY=169.254.169.254,169.254.170.2

Set this value to 169.254.169.254 to filter EC2 instance metadata from the proxy.

Setting these environment variables in the above files only affects the Amazon ECS container agent, ecs-init, and the Docker daemon. They do not configure any other services (such as yum) to use the proxy.
