I am upgrading my projects to helm 3.7 and the helm chart export command in no longer supported.
https://github.com/helm/helm/releases/tag/v3.7.0
Also there is no Documentation for versions previous to 3.7 available. I want to upgrade my project and need to know how to replace the code.
Helm chart export command was used to extract the helm chart to a specific destination after you pulled the helm chart image. On which destination you could then run for example helm install

I ran the following command to install official kubernetes helm charts repository.
helm repo add stable https://charts.helm.sh/stable
The installation was successful as it says.
I wanted to understand where they are installed.
Searched on my home folder, and also ProgramData but could not find.
Any help would be appreciated.
Watching some videos, just found the answer.
Run the following command.
helm env
And you should see all the relevant locations.
And note, this works on ubuntu as well!
These docs describe the helm default file location per operating system.
According to them, your repository files should be under %TEMP%\helm.
I want to install a plugin for fluentd throttle in kuberntes during chart installtion
I found this command: for fluentd
$ gem install fluent-plugin-throttle
but I am new to kuberntes and could not found where to add so it will be installed as part of the chart deployment
If you are using the official (now deprecated) you can supply plugins.pluginsList for the chart to download and install for you.
Take a quick look at the values.yaml of the official fluentd helm chart and you will see in line 42 the following section:
plugins:
enabled: false
pluginsList: []
So basically you just need to edit this file by setting enabled to true and providing your plugins list, so it may look as follows:
plugins:
enabled: true
pluginsList:
- fluent-plugin-throttle
You can even upgrade your already deployed fluentd with such list of additional plugins. You can compare it with this comment about the installation of grafana plugins.
I would like to know which is best between helm template --debug
and helm install --dry-run --debug
Thank you
The difference between the two commands is that helm install --dry-run will send things to a Kubernetes cluster, but helm template won't.
My general experience has been that debugging intricate Go templates can be tricky, and if I'm having YAML issues (and especially if I have the Kubernetes API documentation up in a browser tab) the helm template output is more than sufficient for my needs, and is a little faster and has fewer dependencies. So I frequently use helm template.
In contrast, by the time I've gotten the Go templating logic and YAML formatting correct, I'm usually ready to actually do a test deployment; so when I helm install it's almost never with --dry-run. If I've gotten the object layout wrong this will still complain, and if it's right then I'm ready to start sending requests to the service.
This is an addition to the answer of David
I always use helm template --debug
A common problem when developing helm templates are whitespace errors (for example incorrect indentations).
Only helm template --debug (but neither helm install nor plain helm template) will generate the invalid yaml, which can be used for easy debugging, because the helm error messages are rarely helpful.
I'm currently running helm 3.0.0 in ubuntu and want to upgrade to helm > 3.0.2 for gitlab. The install instructions suggest it's as simple as deleting the helm binary and downloading the new one and the release notes all suggest there are no breaking changes. Could it possibly be that simple?
It should be that simple, provided you put the binary in the right place in your path (i.e. replace the one that you already get from which helm, assuming you're on unix).
You could test it by running some of the following helm commands:
helm version will tell you what you're running.
helm list will
tell you what you have installed in your cluster (add -n
<namespace> for a different namespace)
If you're ok to temporarily install something into the cluster, follow a helm example to install something and then delete it again with a helm delete
Helm Manual instruction clearly says that to install helm - the M+x list-packages menu should contain one. There isn't one - What to do?
