Helm alternative for multiple If-Else conditions
Helm alternative for multiple If-Else conditions
July 8, 2021
Recently I was in a situation where I ended up writing multiple if-else statements in the helm template. As a result, the code block wasn’t clean, and I began to explore alternative ways to achieve the same behavior concisely.
Helm dict function perfectly fits my use case.
Before
{{- if eq .Values.imageType "java" }}
name: openjdk:latest
{{- else if eq .Values.imageType "nodejs" }}
name: nodejs:latest
{{- else if eq .Values.imageType "golang" }}
name: golang:latest
{{- else if eq .Values.imageType "python" }}
name: python:latest
{{- end }}After
{{- $imageTypes := dict }}
{{- $_ := set $imageTypes "java" "openjdk:latest" }}
{{- $_ := set $imageTypes "nodejs" "nodejs:latest" }}
{{- $_ := set $imageTypes "python" "openjdk:latest" }}
{{- $_ := set $imageTypes "java" "openjdk:latest" }}
...
name: {{ get $imageTypes .Values.imageType }}Last updated on
