Monocular API

The API is a golang HTTP RESTFul server. It abstracts away Helm Chart Repository data and provides a simple, idiomatic HTTP interface for search and discovery functionality. E.g.:

• search for official community "stable" and "incubator" charts
• get detailed version information on particular repo/charts
• browse charts in a repo

All commands and relative directories below assume a current working directory at the API source code root, i.e.:

• $GOPATH/src/github.com/kubernetes-helm/monocular/src/api/

Building Monocular

Makefile provides a convenience for building locally:

• make build

The resulting will be placed inside rootfs/usr/bin, which is not coincidentally where Dockerfile assumes a monocular executable will be when building images.

Building Docker Images

To build a docker image locally:

• make docker-build

The image will be tagged as bitnami/monocular-api:latest by default. Set IMAGE_REPO and IMAGE_TAG to override this.

Running Monocular

To launch without building:

$ PORT=8080 go run main.go
serving monocular at http://127.0.0.1:8080

Updating the API specification using swagger

Monocular uses go-swagger to define and generate the RESTFul server code. Makefile provides a convenience for generating server stub code:

• make swagger-serverstub

Testing the API

• make test
