Publishing an Open Horizon Service and Pattern

Having understood what it would take to prepare the service definition, let’s create a simple Service and publish it in the Management Hub. In the previous chapter, we assumed that the container image of the Service exists, which usually may be the case. However, in this book, we will start from scratch.

A typical application development cycle may involve the following steps:

1. Develop the microservice code.
2. Build a container image for the microservice image.
3. Publish the microservice in a container repository.
