How to Use?

Deployment

We briefly describe two deployment options. First, a Kubernetes-based deployment, including the deployment of all other cooking-related tools. Secondly, a stand-alone deployment:

1. See https://github.com/ottenwbe/recipes-manager-deployment for how to run the whole suite of micro-services on a Kubernetes cluster, including the frontend and a database.

2. To run recipes-manager as standalone service (either amd64 or arm64):

   1. Prepare a configuration file (see next section).

   2. Start a database

       docker run -d --name=db-recipes-manager -p 27018:27017 mongo:6
      

   3. Run the container

       docker run -p 8080:8080 --name=backend-recipes-manager -v <local-config>:/etc/recipes-manager/recipes-manager-config.yml ottenwbe/recipes-manager:v0.3.0
      

   4. Check if everything is running:

       curl localhost:8080/api/v1/recipes
      

   5. Details about the API can then be checked in a browser:

       localhost:8080/swagger/swagger_index.html

Building recipes-manager

A Makefile supports the build process. This includes building a development and release version of the recipes-manager service. Furthermore, it includes building docker images to easily deploy the recipes-manager service.

Build Snapshot

make snapshot 

Builds a fully functioning binary named recipes-manager-snapshot. In contrast to the release version, there is still debugging informaiton included.

Build Release Version

make release

Builds a fully functioning binary named recipes-manager.

Docker builds

make docker

Docker Tips and Tricks

• If necessary, stop all container; i.e., if they hang
