Create a helm chart template
2 min read | by Jordi Prats
To get started creating a helm chart on our own there are some common structure that we can reuse from chart to chart: We can let helm create the basic structure for us
To do so we just need to use helm create specifying the name of the chart we want to use:
$ helm create helmproject Creating helmproject It will create a structure as follows:
$ find helmproject helmproject helmproject/Chart.yaml helmproject/values.yaml helmproject/templates helmproject/templates/hpa.yaml helmproject/templates/_helpers.tpl helmproject/templates/ingress.yaml helmproject/templates/NOTES.txt helmproject/templates/service.yaml helmproject/templates/serviceaccount.yaml helmproject/templates/tests helmproject/templates/tests/test-connection.yaml helmproject/templates/deployment.yaml helmproject/charts helmproject/.helmignore It will use the project name we are using for some of the variables it creates such as labels.
$ cat helmproject/templates/_helpers.tpl {{/* Expand the name of the chart. */}} {{- define "helmproject.name" -}} {{- default .Chart.Name .Values.nameOverride | trunc 63 | trimSuffix "-" }} {{- end }} (...) It's a good way of getting started creating a helm chart even though we most likely end up deleting some of the templates or just rewriting most of the template. But that's what templates are for, right?
