How we would ship the container(after running the image). We can only ship the images and run the image to be containerized the platform which we need.(4:53 minute)
Between, nice video. Good job.
Hi Justine, yes you can take it that way. Thanks for watching
@@RaghavPal no sir its my doubt. Can we ship a container
Yes we can
@@RaghavPalhow to ship a container. Can u help
Using docker there are two shipping ways:
You can ship the container and the user can directly run the application.
You can also just ship the Dockerfile and the user can build the container by himself and then run the application.

Hi some project related videos are on Udmey only.
hello Sir, Is it useful For QA in testing ? And How ?
Nitesh
Yes, Docker is very useful for QA in testing in several ways:
Improved Efficiency:
Faster Test Setup: Docker containers create isolated environments for your tests, allowing you to set up them up quickly and consistently without worrying about dependencies or conflicting configurations.
Parallel Testing: You can run multiple tests in parallel across different containers, significantly reducing overall testing time.
Streamlined Test Execution: Docker simplifies managing different test environments and configurations, leading to smoother execution and analysis.
Enhanced Reliability and Consistency:
Isolated Environments: Each test runs in its own container, ensuring consistent execution and preventing interference from other tests or the host system.
Controlled Dependencies: All dependencies are packaged within the container, eliminating issues caused by missing or conflicting libraries on the host.
Reproducible Tests: Docker helps achieve reproducible test results by ensuring the exact same environment is used for each test run.
Increased Flexibility and Collaboration:
Easy Sharing and Collaboration: Docker images can be easily shared and deployed across different QA teams and environments, improving collaboration.
Scalability and Portability: Docker containers can be easily scaled up or down to meet testing needs and run on various platforms, improving portability.
Testing Different Scenarios: Docker allows you to quickly create containers with specific configurations, enabling testing of edge cases and different environments.
Here are some specific ways Docker is used in QA:
Running Integration Tests: Docker containers can be used to mimic different services and dependencies needed for integration testing.
End-to-End Testing: Docker containers can be used to create complex multi-component environments for comprehensive end-to-end testing.
Performance Testing: Docker can help isolate test environments and control resource allocation for accurate performance testing.
Regression Testing: Consistent and isolated containers ensure reliable regression testing results.
Testing Microservices: Docker is the ideal platform for deploying and testing microservices architectures.
Hi Sir, Please cover a topic for kubernetes also..
Sure, I will do soon Suman
Thank you for wonderful tutorials..Am sort of stuck when I was doing practice I used to create different directories on my desktop using mkdir and now have been looking online on how to delete all these directorieson my desktop but I don't seem to get a command do to that. and physically I cant seem to see them on my desktop so that I can delete them manually please help
Hi Roselyne, you can use commands like rm or rm -r, rmdir. Make sure this can remove everything in the folders, So you may want to provide names with wildcards. www.computerhope.com/issues/ch000743.htm
in the case of Java Virtual Machine, you have not a second operating system, haven't it ?
Yes, its not same as docker
JVM is virtualization or containerization ?
