I have seen in many Helm Chart's Chart.yaml where developers provide keywords, as for example
keywords:
- "http"
- "https"
- "web server"
What is the significance of providing these? Are these getting validated by something in Helm? I tried to look out for reasons, but I did not get useful information, so posting here.
The keywords
field specifies a list of keywords about the project. It helps user search charts based on keywords. For example, helm search repo database
will bring up the charts which contain the database
keyword such as postgres
, mariadb
, etc.
Search by keyword:
$ helm search repo database
