Hey Guys, Welcome to my channel - LearnHub. I am Rahul Kinge. Here, you can learn Devops Stuff which includes Dockers, OpenShift, Jenkins and Selenium and Automation Testing as of now. I will keep adding videos but I will need your support here for inspiration.
Hi Rahul i have a question regrading vault agent. I’m working on integrating HashiCorp Vault into our application using Vault Agent for authentication. The initial setup works well, where the application reads the Vault token from a file generated by Vault Agent and uses it to authenticate with the Vault server. However, I’m concerned about handling scenarios where the token’s max TTL is reached, and a new token is generated by Vault Agent. Currently, our application reads the token once during initialization and uses it for subsequent operations. If the token expires and a new one is generated, the application wouldn’t automatically know about the new token, which could lead to failed operations. To address this, I am thinking to implement a file watcher that monitors the token file for changes. When a new token is generated, the watcher reloads the token and updates the Vault client. While this seems to work in theory, I want to ensure that we’re following best practices and not missing any important considerations. Here are the specific questions I have: Is monitoring the token file for changes and reloading the token dynamically the recommended approach for handling token renewal with Vault Agent? Are there any potential pitfalls or edge cases I should be aware of when implementing this solution? Are there more efficient or reliable methods to ensure the application always has access to a valid token, especially in high-availability or production environments? I’d appreciate any feedback or suggestions on improving this implementation.
Hi Rahul So we have to install root certificate is there any way that when any browser open our website in their browser the certificate will installed self or any other way out?
all the browsers by default trust a list of well known public certificate authorities. The only way a browser can trust a new certificate is to manually add (the self-signed certificate or the root CA certificate you generated) to the trusted list on every browser or you need a certificate that was signed by an already trusted CA. The latter one can cost money or use free options like Lets encrypt
pls follow these steps as below: Mine was also Win 8.1 and It works for me. In Control Panel, tap or click Programs, and then tap or click Programs and Features. Tap or click Turn Windows Features on or off. Select Hyper‑V, tap or click OK, and then tap or click Close. Shut down your PC, and then restart it.
In my home pc windows 8 in services I am not having 'Hyper-V Guest Service Interface' also my ram is 4GB only. I have other things related to hyper v like data exchange service, guest shutdown service, heartbeat, etc. Can I still go ahead and install docker following the video?
Hi Rahul, You are providing environment specific parameters from property of xml file and reading system.properties . What if Jenkins job is required and want to pass these parameters so that config file environment specific values can be overwritten Then can you let me know approach? Question is similar to this stackoverflow.com/questions/48575994/how-to-inject-property-file-in-jenkins-and-use-it-values-in-java-code
Use chocolatey to install anything for Windows platform.. I will anyways recommend if you have admin permissions After installation, command would be choco install -y docker
Hi Rahul, Your videos are too good to understand all concepts and very easy to revise all of them in fast pace. But just need small help from you as each video covers a lot of topics and slides so if you share ppts of all videos in github it could be useful for us.Keep on going and add videos relate to kubernetes too. Thank you.
Thanks for these vedios Rahul. Even though I am Front End developer, you have inspired me to be devops developer. Thanks again 😀 and let me know if you can teach me personally.
Hey Rahul, how do you get the URL for the selenium grid installed on docker image? Did you type in that URL in your local browser? (Shown at the end of this video) ? How to connect to the nodes containers? I have windows 10 home on my machine.
Hi Rahul, Can you please explain how to use files located at host to run test cases on containers? In my framework the test cases upload xml files in my application. These files are located in the framework in XMLFiles folder but when I execute the test case in container the file location is not found. Can you please make a video where you upload some file in the application from host to container?
