Hi, Let us have little more details about Chart Repositories.
It's nothing but a simple HTTP server which can host a set of files like index.yaml file and other chart packages.
And based on the get request, it can serve those index.html and the chart packages
and the clients like helm client or other
CICD tools can pull this charts from this server and make use of them. When the charts are ready
I can upload these into the server that is index.yaml file and the chart packages. Chart package is nothing but
the entire chart folder and the index.yaml file
index.yaml file is nothing but that's going to be the index on what are all the charts
available and what versions available
This is going to look somewhat similar to this where I can have n number of entries and what are all the
charts available when it was created
Description about it , the digest to understand what versios being managed
Name and source different informations
And I can have multiple versions
as well. Say for example, in this particular case I do have the version 0.2 and the same entry is available as 0.1
So I can have multiple entries for a chart and the similar way
I can have multiple charts as well.
In this case, I do have charts for Alpine as well as nginx.
This looks very similar to the registry management within the OCI registry or any other source
control system. This is how the configurations will be.
I can have n number of packages and the index.yaml file within the charts folder and that particular
charts folder should be available as a part of some Web server dock root
or it can be hosted as a part of Google Compute Cloud Buckets or AWS
S3 buckets or GitHub pages and we can have our own web server or there is a dedicated server to host the
chart repositories that is chart museum.
We will be having detailed discussion on Chart Museum on how to install, how to configure the
repository within it and make use of it
And we will see a couple of options by using either AWS S3 bucket or GitHub pages.
That's a very simple configuration where I can add the bucket and make use of it.
And once the repository is created, I can use the helm client to push my own chart and see what are
all the versions being managed and pull whatever the version that is required from the particular repository
I can pull it and make use of it.
So the first thing, what I am going to do, I am going to install my own server that is using chart
museum and create a repository and add my own charts within it.
Chart museum is available over here.
This is dedicatedly made to manage the charts and host the chart repositories.
I can do the installation. In the next lecture
We are going to have detailed instructions on how to do the installation and run the chart repository.
And add our own chart within the repository.
