Description
This course is particularly for Spring Developers who wants to learn Docker From Scratch. Along with learning docker, We will also see how docker can be helpful in a Java developer day-to-day life. Increasing Productivity and Quality of our deliverables with the help of Docker. That is the ultimate goal of the course.Here is what we will do in this course:Docker From ScratchWe will start from the story behind docker creation, why developer needs to learn Docker, How docker is different from Virtual Machines.Mastering Docker commands and debuggingCreating Docker Containers and Various run optionsPort Mapping / Volume MappingCreating our own Docker ImagesDocker Networks / Creating custom bridge networkDocker ComposeDeclarative way of creating docker containersPort & Volume mappings with Docker ComposeMongoDB and Mongo ExpressPostgres and AdminerDockerizing Spring ApplicationMicroservice Development with Spring WebFluxReactive MongPackaging our Spring application as Docker ImageRunning our application via Docker ComposeIntegration Testing With Test ContainerImproving the quality of our application by writing integration tests using DockerGenericContainer approachComposeContainer approachMockserverHow Mockserver worksStarting early development process when the dependent service is not ready in Microservices architectureWriting Integration tests along with MockserverAPI Gateway with NginxUsing Nginx for Path based routing and Load balancingNginx + Microservices + Docker Compose to simulate mini cloud in our local for testingAssignment - You will be given a task to do the following Develop a MicroservicePersistence with MongoDBCreate Docker imageRunning the application via Docker ComposeWrite Integration Tests
