AWS EC2

On this page

This guide is designed to get you up and running with a Coder proof-of-concept VM on AWS EC2 using a Coder-provided AMI. If you are familiar with EC2 however, you can use our install script to run Coder on any popular Linux distribution.

Requirements

This guide assumes your AWS account has AmazonEC2FullAccess permissions.

Launch a Coder instance from the from AWS Marketplace

We publish an Ubuntu 22.04 AMI with Coder and Docker pre-installed. Search for Coder in the EC2 "Launch an Instance" screen or launch directly from the marketplace.

Be sure to keep the default firewall (SecurityGroup) options checked so you can connect over HTTP, HTTPS, and SSH.

AWS Security Groups

We recommend keeping the default instance type (t2.xlarge, 4 cores and 16 GB memory) if you plan on provisioning Docker containers as workspaces on this EC2 instance. Keep in mind this platforms is intended for proof-of-concept deployments and you should adjust your infrastructure when preparing for production use. See: Scaling Coder

Be sure to add a keypair so that you can connect over SSH to further configure Coder.

After launching the instance, wait 30 seconds and navigate to the public IPv4 address. You should be redirected to a public tunnel URL.

That's all! Use the UI to create your first user, template, and workspace. We recommend starting with a Docker template since the instance has Docker pre-installed.

Configuring Coder server

Coder is primarily configured by server-side flags and environment variables. Given you created or added key-pairs when launching the instance, you can configure your Coder deployment by logging in via SSH or using the console:

ssh ubuntu@<ec2-public-IPv4>
sudo vim /etc/coder.d/coder.env # edit config
sudo systemctl daemon-reload
sudo systemctl restart coder # restart Coder

Give developers EC2 workspaces (optional)

Instead of running containers on the Coder instance, you can offer developers full EC2 instances with the aws-linux template.

Before you add the AWS template from the dashboard or CLI, you'll need to modify the instance IAM role.

Modify IAM role

You must create or select a role that has EC2FullAccess permissions or a limited Coder-specific permissions policy.

From there, you can import the AWS starter template in the dashboard and begin creating VM-based workspaces.
