Terminal coding assistant with a launch-created sample workspace and ordinary-user execution.

What is on the image

This guide matches Marketplace package 0.1.0 (OpenCode 1.19.4). Check the listing for the version currently on offer.

  • OpenCode 1.19.4, run from the terminal as ubuntu.
  • A sample file, /var/lib/opencode/workspace/calculator.py, prepared on first boot. Later boots keep existing work.
  • A labelled local fixture that edits files and checks them with Python. It does not call a paid model. Its result and the original mode 0600 output are under ~/opencode-demo.
  • A walkthrough, /opt/sushi/docs/demo.sh, and image notes at /opt/sushi/docs/README.md.
  • Source and component notices under /opt/opencode/inputs and /usr/share/doc/opencode.

There is no persistent web listener, browser URL, or inbound application port. You do not forward a port for OpenCode itself.

t3.medium (4 GiB of memory), x86_64, with IMDSv2 and an encrypted gp3 root volume of at least 32 GiB. That size is what the listing usage instructions say. The getting-started page linked from the listing says 24 GiB. Use 32 GiB so the launch matches the usage instructions.

Attach an instance profile that can use Session Manager. Allow the outbound access Session Manager needs, and the outbound access your model provider needs. Leave application ports closed.

Billing

The listing states a software rate of USD 0.03 per running instance-hour. Confirm the offer before you subscribe. EC2, EBS, data transfer, and your model-provider usage are billed separately. The supplied local fixture does not call a paid model.

Where to go next

  • Getting started: subscribe, launch, run the fixture, and send one task to Amazon Bedrock.
  • Configuration: where the sample lives, and how the Bedrock role is selected.
  • Operations: backups, replacement instances, and support.
  • Troubleshooting: when the fixture and a model call tell you different things.
