You can see all of the repositories (the remote locations for downloading charts) that you have added to your helm installation:$ helm repo listNAME URL kedacore stable -charts.storage.googleapis.com/openfaas -netes/ jenkins bitnami concourse -charts.storage.googleapis.com/Search for a chartUsing helm search will search either Artifact Hub (hub option) or all repositories configured on your system (repo option):
To get information about a chart, or its values, use helm show, with chart or values:$ helm repo add concourse -charts.storage.googleapis.com/$ helm show chart concourse/concourse$ helm show values concourse/concourseInstalling and managing chartsThe most common way people make use of Helm is to find and install charts onto a Kubernetes cluster. Here are the main commands you might use when installing charts.

You can install Helm charts through the UI, or in the declarative GitOps way.
Helm is only used to inflate charts with helm template. The lifecycle of the application is handled by Argo CD instead of Helm.Here is an example:
Before v2.6 of Argo CD, Values files must be in the same git repository as the Helmchart. The files can be in a different location in which case it can be accessed usinga relative path relative to the root directory of the Helm chart.As of v2.6, values files can be sourced from a separate repository than the Helm chartby taking advantage of multiple sources for Applications.
Helm templating has the ability to generate random data during chart rendering via therandAlphaNum function. Many helm charts from the charts repositorymake use of this feature. For example, the following is the secret for theredis helm chart:
Helm is a popular package manager for Kubernetes that simplifies the deployment and management of applications on the platform. One of Helm's powerful features is its ability to render chart templates, allowing users to visualize the configuration of their Kubernetes resources before deploying them. In this article, we will explore how to render chart templates locally using Helm, providing step-by-step instructions and examples to help you get started.
If you're interested in applying a local chart directory, or a chart pulled from a repo that exists locally as a tar archive, then bundle mode can come handy. Let's say we have a chart named my-chart.tar.gz in the current directory, we can use the bundle mode to deploy it during vCluster initialization as follows:
The caching strategy is to pull a repository index from the cache if it isavailable, otherwise to load the index, retrieve and build the chart,then cache the index. The cached index TTL is refreshed every time theHelm repository index is loaded with the helm-cache-ttl value.
The difference is that the repository could either refer to a remote chart repository, such as the one we use to store our Aqua Security Helm Charts, or it could refer to another directory that you have locally.
The helm dependency update command has two main functions. First, it is responsible to verify that the Charts specified in the Chart.yaml file are present in the ./chart directory at a valid version. It then pulls the dependency as specified in the Chart.yaml manifest. This includes updates to the charts. A Chart.lock file will then contain the most recent specifications of the chart.
When using the oc-mirror plugin, you specify which content to mirror in an image set configuration file. In this YAML file, you can fine-tune the configuration to only include the OpenShift Container Platform releases and Operators that your cluster needs. This reduces the amount of data that you need to download and transfer. The oc-mirror plugin can also mirror arbitrary helm charts and additional container images to assist users in seamlessly synchronizing their workloads onto mirror registries.
You must specify a storage backend in the image set configuration file. This storage backend can be a local directory or a registry that supports Docker v2-2. The oc-mirror plugin stores metadata in this storage backend during image set creation.

Now that you have defined the Flask app, add a Dockerfile to containerize the app. We will use Python 3.9.1 base image from Docker hub. Create a Dockerfile in the flask-helm-charts-circleci directory and add this code snippet to it.
You may want to test the setup locally, before automating the deployments using CircleCI. This section describes how to manually push the image and Helm chart to AWS ECR and deploy the Helm chart to the AWS EKS cluster. If you want to directly automate the deployments using CircleCI, you can skip this section.
When an existing Helm chart on a cluster is updated, you need to use the helm upgrade command instead of helm install. You can define a shell script that checks whether a chart with the name flask-helm is already deployed on the cluster and whether it uses the appropriate command. Create a file at scripts/deploy-flask.sh and add this to it.
