Jit and gira, my favorite tools

[@SimplilearnOfficial]

Haha! our mistake.

[@himikasarkar8510]

I had to think for a sec!

[@uibeomful]

I just wanted to say thanks for the tutorial. I'm an old schooled developer and always have fear when learning a new thing. This tutorial is my first TY video about Docker and gave me a good feeling about using Docker. Also, thanks for covering the other related topics which are essential, and they are very easy to understand. Thanks!

[@eltonmombeshora6183]

Thank you very much! This really helped me get the pieces together. I'm on an internship working on a DevOps team, and this helped me understand better my role and how cloud computing tools and features like CI/CD link with docker. Thank you so much!

[@Albert-fe8jx]

I wondered about licenses for the operating systems. Is a license required for each os guest image? What about non-open source database engines?

[@SimplilearnOfficial]

Hi Albert, thanks for watching our video. When you install Jira via docker, you still need a proper licence - e.g. a demo licence for testing. And when you install an open source database like MariaDB, you can do it as often as you would like in the non-docker world. Also, When you install several Windows-es on several virtual machines, you need several Windows licenses, and so on. Hope that helps!

[@saurabhgarg8316]

Hi First of all thanks for a nice intro on docker. I had a doubt in my mind, please clear it. If I want to run docker on windows how about the support for soft-wares like Redis DB for which no production version is available for windows can we still run it in docker. While in VMware we will be able to run it on same windows machine. If we cannot, I see it one advantage of VMware over docker due to which it is preferred in industry (Hardware cost benefits).

[@sreenivasannarayanan8439]

Hi there, I'm a fresh graduate in Computer Science having limited work experience. As a result of Covid-19, I lost my job as a technical support personnel and terribly perplexed to what can be done. I am looking out for an entry back into the IT market. I have limited working experience as a programmer. Will a certification in docker help me build my resume ? Hoping to hear back from your team. I'm really curious to know more about this. Thanking you, Sreenivasan

[@dillydadally]

[@DEIVID01VIDEOS]

I very rarely finish a video and think about commenting it. This was a great video, thank you.

[@monday6740]

0:30 Traditionally, the answer to this question was : have the environment on a server. Developers then all connect to the server, which runs production and test environments.

[@SimplilearnOfficial]

Thanks for your input!

[@jcxmej]

I would like to know the difference between creating an environment and a docker

[@SimplilearnOfficial]

Creating a docker is intsalling the docker tool where as creating an environment is setting up the components of docker. components such as client, daemon, dockerfile, docker images, docker container

[@andreiasimov33]

I'm amazed by how well you explained it. I've been checking other two tutorials but I was not really getting it, also it didnt help that they were using a too technical knowledge.

[@stheday1]

If a container has a Windows Service application for dependency, could that be included in the container image? How is it started? Would the Windows Service application have to be installed on the host OS and all containers would see it?

[@prithviabilash7713]

I hope Simplilearn answers this and other questions like this, instead of just thanking and responding to messages that say "good video !"

one question I had for example If I have multiple versions of the same web application /(or websites which run on same os) then I can deploy all of them on a single vm or in a docker. Only difference will be isolation in this scenario. Am I right to think so???

I am working on a Django project with a friend. He uses PC and I use Mac. Should we work on our project running on localhost or on Docker from the start, or when we are ready to deploy it for our client? (P/s: We are new developers, fresh out of bootcamp)
