Docker Agent

by DockerFramework / SDKdocker.github.io

Docker Agent builds and runs AI agents from a declarative YAML file: give an agent instructions and tools, including any MCP server, let agents delegate to each other, and push the result to an OCI registry to share it. Opper ships as a built-in provider alias, so you set OPPER_API_KEY and write the model as opper/<model>, with no base URL to configure, and Docker Agent also picks up OPPER_API_KEY for its automatic model selection.

Build with Docker Agent on Opper

Opper ships inside Docker Agent, so there is no base URL to set and no package to add. Set OPPER_API_KEY and pick a model.
