Building and deploying the microservices

Building, deploying, and verifying the deployment using the test-em-all.bash test script is done in the same way it was done in Chapter 19, Centralized Logging with the EFK Stack, in the Building and deploying the microservices section. Run the following commands:

1. Build the Docker images from the source with the following commands:

   cd $BOOK_HOME/Chapter20
   eval $(minikube docker-env -u)
   ./gradlew build
   eval $(minikube docker-env)
   docker-compose build
   

The eval $(minikube docker-env -u) command ensures that the ./gradlew build command uses the host’s Docker engine and not the Docker engine in the Minikube instance. The build command uses Docker to run test containers.

2. Recreate the namespace, hands-on, and set it as the default namespace:

   kubectl delete namespace hands-on
   kubectl apply -f kubernetes/hands-on-namespace.yml
   kubectl config set-context $(kubectl config current...
