The Complete Microservices With Java

Implement microservices design principles by exposing data through public APIs, hiding implementation details, selecting appropriate tools, and enforcing security with OAuth and OpenID Connect.

Install the Gradle build tool by following official instructions, study it manually, run the required commands to install, and verify the installation.

Examine the technical design of a locations microservice, including a location data model, a database-backed service, and endpoints for retrieving, creating, updating, and deleting locations.

Create a basic model by extending a base entity into a location and a country, and populate static data for countries and states to support the application.

Create a rest locations resource in a java microservices project, wire a locations service, and implement a get endpoint with a dummy response to verify the API before database integration.

Create a patient database and its table with a primary key and columns like country, state, time, location. Configure host and root user, and connect the database to the application.

Build a data access layer with a mapper in a Java microservices environment, implementing a DAO to map database rows to location objects and manage ID, code, and country fields.

Create the locations service and implement its business logic in the complete microservices with Java course, including retrieving patients from the database, mapping to models, and exposing endpoints.

Implement the getLocation method in the location service to retrieve a single location by id, wiring input through the service and data layers and returning a public response.

Create a post endpoint for inserting new locations, serialize a location object with content and properties in the request body, insert into the database, and return a 200 OK response.

implement editing locations by updating a location identified by id using the location service, and return void. update the location's code and name properties and verify the endpoint with postman.

Explore the life before Docker, learning to prepare the development environment, configure frameworks, set up databases, and deploy to production with staging.

Create a dockerfile to build a Java application image with dependencies, copy the jar and config files into the workspace, expose required ports, and run the application in a container.

Prepare files for the docker environment. Copy content to the application area, configure services, and build the final image for deployment.

Refactor before creating the docker image by preparing configuration and dependencies, copying environment and source files into the app space, and ensuring a secure executable service runs from outside.

Create and run docker containers to build and publish content, expose ports to a browser, configure host networking, use images and content IDs, and manage services with Docker Compose.

Create and configure a docker compose file to deploy three services, including a database, using compose file format version 3, with image references, environment variables, and persistent volumes.

Develop a docker-compose setup for phpmyadmin by defining an admin service image, exposing a localhost port, setting root credentials, and linking content and script containers.

Learn to install Kubernetes locally using VBox, kubectl, and Minikube, manage containers, deploy services, access the Kubernetes dashboard, and prepare storage for databases.

Deploy microservices to a local Kubernetes cluster by building images, configuring services and deployments, and ensuring proper binding and environment setup.

Apply and verify local kubernetes deployments for microservices, including creating, redeploying, and validating services, while monitoring deployment status and issues.

Point kubectl to the cloud cluster by creating a location services cluster, configuring credentials, and setting the proper context to verify the cluster is cloud-connected.

Create Gradle tasks to build and push an image to Google container registry, using production environment tags, hostnames, and project identifiers in the workflow.

Configure production environment descriptors by setting up a secure database proxy, host name, and certificates. Define locations services endpoints and backend paths for deployment and routing.

Create production deployment descriptors by configuring deployment annotations, image references, secrets, and environment variables. Learn how to map registry images, ports, volumes, and certificates for a secure production setup.
