Java version of the "Docker and Kubernetes: The Complete Guide" course

source code for the Java version of the "Docker and Kubernetes: The Complete Guide" course

AWS Elastic Beanstalk version (Up to 11.-Multi-Container Deployments to AWS section) is on the elastic-beanstalk subfolder:

Execute it locally using

$ cd elastic-beanstalk

$ docker-compose up --build

Navigate to http://localhost:3050/

Continuous Integration with Travis CI + Amazon AWS

• The repository must be created on https://github.com/

• The repository must be assigned from GitHub on https://travis-ci.com/. The following setting variables must be set up:

1. AWS_ACCESS_KEY (for 11.-Multi-Container Deployments to AWS)
2. AWS_SECRET_KEY (for 11.-Multi-Container Deployments to AWS)
3. DOCKER_ID
4. DOCKER_PASSWORD

• The following instances must be created on Amazon (for 11.-Multi-Container Deployments to AWS)

1. Elastic Beanstalk (EB)
2. Relational Database Service (RDS) for Postgres
3. ElastiCache for Redis
4. Custom Security Group
5. Identity and Access Magagement (IAM)

Kubernetes minkube local version (From 12.-Onwards to Kubernetes!) is on the multi-container-minikube folder:

Execute it locally

1. Create the secrets for the postgres password: kubectl create secret generic pgpassword --from-literal PGPASSWORD=postgres_password
2. Execute the mandatory kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/mandatory.yaml Ingress Nginx command
3. Enable Ingress using minikube addons enable ingress
4. Install all the Kubernetes objects with kubectl apply -f k8s
5. Get the local IP with minikube IP
6. Browse to the local IP

Kubernetes Google Cloud version (From 12.-Onwards to Kubernetes!) is on the root folder:

• The repository must be assigned from GitHub on https://travis-ci.org/. The following setting variables must be set up:

1. DOCKER_ID
2. DOCKER_PASSWORD

Within the code you can see how to

• Create different Docker Container Types and relate all of them
  1. React Client App
  2. Java Spring Web Framework API with Maven
  3. Java Maven Console
  4. Postgres
  5. Redis
  6. NGINX
• Use Postgres from a Docker Container with Java
• Use Redis from a Docker Container with Java creating a subscription on the Web API App and subscribe to it on the Console App.
• Accept dynamic POST request with Java Spring Framework Web API
• Send dynamic JSON responses from Java Spring Framework Web API
• Use Docker Compose to run and relate easily different Docker Components
• Use NIGIX Container to run the React Client App
• Use NIGIX Container as Reverse Proxy with Java Spring Framework Web API
• Work with different AWS Amazon service types to deploy a multi container Docker application using AWS Elastic Beanstalk
• Upload own Containers to Docker Hub and download them with the deployment
• Use Travis CI for the Continuous Integration Workflow
• Use Kubernetes to run the same multi container application
• Use Minikube to run Kubernetes locally
• Use Kubectl CLI for interacting with Kubernetes Master
• Use Google Kubernetes Engine to run the Kubernetes Cluster on the Cloud
• Run the Ruby Travis CI CLI from a Docker container locally
• Manage the automatic creation and renewal of a TLS certificate using Kubernetes to run the application with HTTPS
