Thanks Mukesh....You and Naveen is builder of my Career

[@Mukeshotwani]

Thank you Nitish for following us :) Keep learning.

[@AbhishekMishra-ru2fi]

Great champion.Please cover all topics . Cant wait to learn everything about Docker.

[@SameerKumar-yu1xi]

Thank you for making docker simpler for us to learn...

[@Mukeshotwani]

Thanks Sameer Bhai.. 🙂

[@mayurchaudhari1111]

@Mukesh Otwani Thanks for the video. I always love watching your videos. Just to Highlight the exact issue caused around 12.27 min was, a container with the same name already present and it was not running but allocated the same name which you were passing at the time of running the new container. If you would have changed name while running the new container that also could have done the task. But it's also ok that you removed the container and created a new.

[@Mukeshotwani]

Thanks Mayur, noted your point.

[@mayurchaudhari1111]

​@@Mukeshotwani Love your dedication man. Want to meet you once for a DevOps talk.

[@ramkumariyer8282]

This was very useful . I was able to setup grid with multiple chrome nodes too . But my main concern is when i was running the entire thing in VM with batch files the execution was faster but in this approach with Docker my tests are running very slow and are getting time out / element not found issues . Do you have any suggestions for that ? I created 1 HUB with Multiple (Say 10 Chrome Nodes) and executed them with batch files . They are working well but running very slow .

[@jayakrishnank4001]

Hi Mukesh, How can we run docker file and execute cases through Jenkins

[@nikhilgupta5721]

Thanks Mukesh. It will be very good if you share video on how to shut and start all nodes before and after the execution with running only one file before starting the testng.xml most of the time what happens you know node is not in the up conditon or it got hanged. Also try to show distributing 25 test cases considering 5 selenium-chrome-node and distributing 5 each test cases at the same time on all 5 nodes registered with hub.

[@Mukeshotwani]

Nihil have u tried Zelenium ?

[@prachijoshiporwal3353]

To run restassured api selenium automation projects on docker ...is that possible only through selenium grid ?

[@uhsay1986]

Hi Mukesh, is vmc viewer used in corporate projects ? Or there is a different practice

[@Mukeshotwani]

Yes Its for debugging so yes it is used.

[@PianoNumberOne]

Thanks Mukesh...for sharing this...

[@Mukeshotwani]

Most welcome Pankaj.

[@ashwinnetalkar2992]

Hi Mukesh can we use docker to run mobile test automation on a virtual machine?

[@Mukeshotwani]

Hi Ashwin, I haven’t tried mobile part but seems can be done because they have provide images for appium too hub.docker.com/r/appium/appium/

[@ashwinnetalkar2992]

Actually the requirement is to run mobile test on virtual machine windows 10 clonned on linux based CentOS.

[@Mukeshotwani]

Give a try Ashwin, seems interesting thing to try

[@anitashaw5479]

Hi Mukesh, I am using windows 10 pro, and installed Docker desktop and able to download the images but could not able to link the node to running hub. I searched in Google with this error but no luck. Could you please give any hints on the same. Waiting for your reply

Hi mukesh sir. In each container can i launch 5 chrome browsers? Or in 1 container i can launch only 1

[@Mukeshotwani]

Hi Arun, you can configure it these settings with docker file..

[@balamuruganvaithyanathan379]

Hi Mukesh, while I try to connect my container in VNC viewer I am getting "The requested address is not valid in its context. 10049" error. Do you have any idea to solve this issue?

[@Mukeshotwani]

No Bala, I am not sure with this error. Are you able to trigger the test on docker container? You can also try Zalenium and here you can get video recording of test and you can directly access the containers from dashboard itself. kzbin.info/www/bejne/hnbNhnahg8unbdU

Hi Mukesh, Very good video as usual, And you make it so easy. I have one question wrt docker image which you installed. Does the Docker image "Selenium/hub" contain all the required software to run selenium script like "Selenium Server", " Maven" "TestNG" etc as well apart from Selenium Hub(grid).

[@Mukeshotwani]

Hi Prashanth, Docker will only create run time environment for you with grid installed. Maven, TestNG and jenkins are not part of it. You just need to provide hub url in your test and it will run on docker container. I would also recommend you to try kzbin.info/www/bejne/hnbNhnahg8unbdU

[@prashantht.v8289]

@@Mukeshotwani Thanks Mukesh,So Docker is used in selenium automation only for Grid usage and running on multiple browsers is it?

[@naresh1p334]

Hi Mukesh,as per the lecture I have installed docker on 'windows machine' and configured hub and nodes and its working fine. my question here is, can we create a node in mac machine and link to same hub which was configured in windows..if yes could you please explain me how we can achieve this? Please post the lecture links if you have any Note:We should not install a docker again on Mac machine to achieve this.

[@Mukeshotwani]

HI Naresh, if you want to connect node in MAC then you need to have docker then only u can run docker containers. Once you have node connected to hub you can trigger through hub.

[@chandananand1640]

Hello.. Mukesh How can we specify the version of browsers in the containers

[@Mukeshotwani]

Hi Chandan, by default it gives latest version of Browsers. If you want to change versions then you can need to make changes in docker file and build the image and then use it. github.com/SeleniumHQ/docker-selenium

[@shivamgoyal4751]

Can I launch chrome and Firefox both in a single container?

[@shivamgoyal4751]

In my case, I need to launch Chrome and Firefox in the same class to check synchronization. So I mentioned the same URL(http:IPAddress/wb/hub) in the RemoteWebdriver field for both Chrome and Firefox, and it launched chrome in one RealVNC server and Firefox in another. Now I need to execute my class(without any change) 50 times in parallel, what will you suggest?

[@KhushbooVerma2810]

Hello, I am searching something where I can run .bat file which is in remote machine(to create node) directly from the local machine. Instead of going to the remote machine n initiating it manually. not allowed to download any other application for this, can you please help with the cmd to run.

[@Mukeshotwani]

Hi Khushboo, what is your exact requirement. I mean you want to use docker here? running batch file from jenkins then you can create slave in Jenkins and provide the path of batch file.

[@KhushbooVerma2810]

@@Mukeshotwani i have not tried Jenkins yet. Will try it now. Actually I have VDI where i manually run cmd to create node after creating hub . And then start the automation script to run parallel execution on node machine. Just wanted to know if there is any cmd ao that i can create node in vdi machine instead of doing it manually. Hope i am clear now 🙈

[@Mukeshotwani]

Hi Khusbhoo you can run cmd commands in Jenkins as well or you can run batch file from jenkins. Quick question- Is this mandatory for you to run test on VDI machine? Docker makes this task easy by creating container.

[@KhushbooVerma2810]
