If your key value is stored in env-values.yaml file but why you took {{ range.values.examplemap }} instead of {{range.env-values.examplemap}} because your environmental value is stored inside env-values.yaml file....so I am in confuse sir

Thanks for a good video again. How all other values will be replaced if we customize the file name and only pass replicaCount. ? will other parameters will be passed via older values.yaml file

Hey Bro.. first of all thank to this great tutorial..i really enjoyed it..bro i have a question is,, changing the replicas using a value.yaml file is really good idea but bro when we change the replicas i mean using < helm install -f values.yaml myhelloworld hellowolrd > comand then we have to delete the previous helm chart.. right? then what is the benifit of using values.yaml file if it cant increase/decrease the replicas when our helm chart is running coz we can directly increase or decrease the RC even through our< kubectl apply -f > command..? please bro explain me... thanks again for your quick response... Have a good time bro

if you do install then yes and you need to provide a different name as well else it will fail. You can use helm upgrade --install so if it is not installed it will install it and if it is installed then it will upgrade it. there is a lot of benefit I think as the command I told you is easy to use and you can just use helm upgrade if you know you have already installed the chart

How to pass a values to values.yaml file when heml is running in CI/CD pipeline. for ex: we need to send a values from Github environment to helm values.yaml. so that no need to maintain multiple value.yaml file for each environment.

[@Fayaz-Rehman]

Great - Thank you - you can also use "helm show values [chart] .. " for verification. Question - can we use kubectl scale deployment helloword-1 --replicas=3 with helm charts...

[@RahulWagh]

yes you can use **_kubectl scale deployment helloword-1 --replicas=3_**, it should work as normal . //Rahul

@@RahulWagh Thanks

[@amitbikram5455]

Can we change the configuration files or the parameter value in a particular configuration files in same manner?

[@RahulWagh]

Yeah you can do it but probably you need to reapply or at least run helm install again

[@sudheerkumar-ne4jn]

Nice session , would these variables set to docker container env args ? I have few env args from docker file and entry point needs few values , how would i supply docker containers entry point arg from helm ? Example : spring cloud config server host url and spring profile name for docker entry command from helm command ? Thanks in advance 👏👏👍

[@RahulWagh]

I have not tested accessing those variable inside the docker container but I highly doubt it will be accessible inside the docker container

How to update override the values of *dependent* chart. For example I would like to override values of dependent elasticsearch chart.

[@DheerajKumar-rt7zd]

I don't think it is possible. What you can do is extract the tgz file of chart and make changes works for me but then it will not work remotely. Other way is just to create an override values yaml file and use with -f as he mentioned

How to add kubernetes secret as an environment variable in helm?

[@RahulWagh]

Well you need to have secret plugin of helm installed and after that you need to generate pub and private key pair for encryption part of the secret. After that you need to store private key somewhere and can share the public with the counterpart. I will be preparing an session in upcoming because its hard to explain everything in the comment section but stay tuned your question will be answered into that session.
