Troubleshooting Docker

Problem - Caused by: com.spotify.docker.client.shaded.javax.ws.rs.ProcessingException: java.io.IOException: No such file or directory
Solution - Check if docker is up and running!
Problem - Error creating the Docker image on MacOS - java.io.IOException: Cannot run program “docker-credential-osxkeychain”: error=2, No such file or directory
Solution - https://medium.com/@dakshika/error-creating-the-docker-image-on-macos-wso2-enterprise-integrator-tooling-dfb5b537b44e

Removed subprocess.CalledProcessError: Command '['/usr/local/bin/docker-credential-desktop', 'get']' returned non-zero exit status 1 I had this: cat ~/.docker/config.json {"auths":{},"credsStore":"", "credsStore":"desktop","stackOrchestrator":"swarm"} I updated to this: {"auths":{},"credsStore":"","stackOrchestrator":"swarm"}

Course Overview

******* Course Overview *******

Architectures are moving towards Microservices and Cloud. Docker makes it easy to containerize your applications and make them cloud ready.

Docker is the No 1 Tool to Containerize your Java Spring Boot Applications. Learning Docker would help you streamline your deployment processes and experiment easily with new frameworks and tools.

In this handson course, we will containerize - create docker images and create containers - for a variety of Spring Boot Applications:

REST APIs - Hello World and Todo - Jar
Todo Web Application War
Full Stack Application with React and Spring Boot
CCS and CES Microservices
Eureka Naming Server and Zuul API Gateway

This course would be a perfect first step as an introduction to Docker.

You will be using containerizing a variety of projects created with React (Frontend Framework), Spring Boot (REST API Framework), Spring (Dependency Management), Spring Security (Authentication and Authorization - Basic and JWT), BootStrap (Styling Pages), Maven (dependencies management), Node (npm), Visual Studio Code (TypeScript IDE), Eclipse (Java IDE) and Tomcat Embedded Web Server. We will help you set up each one of these.

What you'll learn

You will Learn the Fundamentals of Docker from Zero, no previous experience required
You will learn the important Docker Concepts - Registry, Repository, Tag, Image, Container and Volumes
You will learn the important Docker commands
You will understand the Docker Architecture
You will create Docker images for 8 Java Spring Boot Projects
You will learn to use Dockerfile to Automate Building of your Docker Image
You will learn to use various maven plugins - Dockerfile Spotify Plugin, JIB Plugin and Fabric8 Docker Maven Plugin - to create Docker images
You will learn to create best practices with creating Docker Images - Improve Caching of Docker Images and create Multi Stage Docker Builds.
You will Containerize Java Spring Boot Todo Web Application talking with MySQL
You will Containerize Java Spring Boot React Full Stack Application with Docker
You will Containerize CCS, CES Microservices, Eureka Naming Server and Zuul API Gateway with Docker and Run them using Docker Compose
You will learn to run MySQL, RabbitMQ and Zipkin as Docker Containers
