Add ChartMuseum Repository

In this tutorial, we will discuss how to add the ChartMuseum repository as a part of our helm client. The ChartMuseum is running, and it’s listening in port 8080.

Now it’s time to recall the repository discussion that we had in the beginning. We had a quick overview of what a repository is and how it works.

The repository is very similar to the APT or yum repository that we have as a part of the Linux systems, where it will have a collection of packages.

Whenever I wanted to install a package, First, I need to add the reference to the repository where it is located and gave an alias name to it.

So once the reference is added to the list of repositories, any package that I wanted to install. It’s going to search within that specific repository list that we have. And for that, we do have a command called repo list.

ashok@waytoeasylearn:~$ helm repo list
NAME       URL                                        
stable     https://charts.helm.sh/stable

In the beginning, we added the stable repository to try out a few of the charts. And this is the URL that we had provided. If you remember, this is the URL where the charts are added.

So the location for our repository is it is running in my cluster node. Now I can provide the IP address of my cluster node and add this particular repository with the name.

Add Repository

So I’m going to use the helm repo add command and give a name to it helm repo add and provide a name and the URL.

ashok@waytoeasylearn:~$ helm repo add mychartmuseumrepo http://192.168.1.50:8080

So I gave the name mychartmuseumrepo and the URL where I do have the chart museum running. It is running in this specific IP address. I’m providing the IP address; I wanted that to get access from any location. If you’re running it in the local machine, you can give localhost as well.

So the repository will get added. Now I can go ahead and list the repositories available.

ashok@waytoeasylearn:~$ helm repo list
NAME                    URL                          
stable                  https://charts.helm.sh/stable
mychartmuseumrepo       http://192.168.1.50:8080

So I do have mychartmuseumrepo that got added just now. Now I can go ahead and search the charts available. It’s going to search in both the repositories.

ashok@waytoeasylearn:~$ helm search repo nginx
NAME                            CHART VERSION   APP VERSION     DESCRIPTION

stable/gcloud-endpoints         0.1.2           1               DEPRECATED Develop, deploy, protect and monitor…

It’s going to search for the chart with the name Nginx. And as of now, it is available only within the stable, and there are no charts available within the mychartmuseumrepo.

So nothing is getting listed. Since the repository that we have is a new repository, there will not be any chart. I can go ahead and search as well using the following command.

ashok@waytoeasylearn:~$ helm search repo mychartmuseumrepo
No results found

The repo doesn’t have any chart. If I search for stable, it will search all the charts available within it, and their name and version will be listed.

Summary

In a quick summary, we discussed adding the repo and referring to the chart museum that we had created. In the following tutorial, we will create a chart, add it to our repository, and manage it.
