Rebuild PetClinic

Before we can build the new services with the updated log format we need to add the OpenTelemetry dependency that handles field injection to the pom.xml of our services:

. ~/workshop/petclinic/scripts/add_otel.sh

Dependencies added successfully in spring-petclinic-admin-server
Dependencies added successfully in spring-petclinic-api-gateway
Dependencies added successfully in spring-petclinic-config-server
Dependencies added successfully in spring-petclinic-discovery-server
Dependencies added successfully in spring-petclinic-customers-service
Dependencies added successfully in spring-petclinic-vets-service
Dependencies added successfully in spring-petclinic-visits-service
Dependency addition complete!

The Services are now ready to be built, so run the script that will use the maven command to compile/build/package the PetClinic microservices:

Note

Note the -P buildDocker, this will build the new containers and take 3-5 minutes to complete.

./mvnw clean install -D skipTests -P buildDocker

Given that Kubernetes needs to pull these freshly built images from somewhere, we are going to store them in the repository we tested earlier. To do this, run the script that will push the newly built containers into our local repository:

. ~/workshop/petclinic/scripts/push_docker.sh

The push refers to repository [localhost:5000/spring-petclinic-vets-service]

The containers should now be stored in the local repository, let’s confirm by checking the catalog:

curl -X GET http://localhost:9999/v2/_catalog
