Hi Abhishek, before watching your videos, the concepts looks like a huge mountain, but your video makes that into dust particles, as if nothing is there in it. Clear explanations, precise things, what more to say.... you are really awesome.... Thankyou so much for your contribution to the community... Hatsoff....

15:50 we use kubectl apply... over kuberctl create... Because when apply cmd is used, we can simply kubectl edit... the concerned files, without applying again. In kubectl create..., you can't use use kubectl edit, you need to manually change the YAML and and create again.

@Tagore-lv1wc 3 ай бұрын

When we use "kubectl create", it creates a new resource based on the provided configuration file.If the resource already exists, kubectl create will return an error, indicating that the resource already exists. It's typically used for creating resources that don't already exist in the cluster. "kubectl apply" is used to create or update resources based on the provided configuration file. If the resource already exists, kubectl apply will update the existing resource with the new configuration. kubectl apply is idempotent, i.e., we can apply the same configuration multiple times, and it will ensure that the resource is in the desired state. It's commonly used for both creating new resources and updating existing ones. I think this clarifies well😊

Configmap is used to store data , this data can be later used by containerised application as environment variables or fileas volume mount

Yes. . just base64 encryption on the secrets level .. which is very simple to debug for anyone . It also gets encrypted at the etcd

Hi Abhishek, If we use configmap as env variables, developers will use directly from it. How will they utilise the values if we attach cm as volume mounts?? Is it by reading the value in those particular files ??

Thank you Abhishek. Don't mind, I am just asking in curiosity. If I have configured this DB_PORT as volume mounts and we should use it as below right ? DB_PORT=$(cat /opt/db-port | more)

@engineerbeings3156 5 ай бұрын

I have one simple question If we use volumeMount how developers will fetch the value for application ? Is this the way secret_file_path = "/path/to/mounted/secrets/mysecret.txt" with open(secret_file_path, 'r') as file: secret_value = file.read()
