Dockerfile

# The AgentKit frontend image (BuildKit gateway).
#
# Referenced as the build syntax of an agentkitfile.yaml:
#     #syntax=ghcr.io/sozercan/agentkit/agentkit:latest
# BuildKit pulls this image and runs /bin/agentkit as the gateway frontend, which
# turns a `kind: Agent` file into a standard OCI image of a tool-using agent.
#
# Mirrors AIKit's root Dockerfile: a static, CGO-free build of ./cmd/frontend
# from a golang builder, shipped FROM scratch with just CA certs + the binary.
