we are defining a initContainer for our helm chart. relevant part is the following
initContainers:
- name: "set-volumes-init"
image: "IMAGE AND TAG"
command: ['sh', '-c', 'COMMAND 1 && COMMAND 2 && COMMAND 3']
volumeMounts:
- name: volume-summary
mountPath: /usr/summthe question is: how do i make the "command" like have the different commands according to if a value is defined or not?
e.g: if i have the value: podx.val2 defined, i want the COMMAND 2 to be included, but if its not, then i dont want it.
same for other COMMANDS
If I were doing this, I'd build a custom image that contained the shell script, and have it controlled by environment variables.
#!/bin/sh
if [ -n "$DO_COMMAND_2" ]; then
command2
fiThe style you've written could work with a combination of YAML block syntax and Helm conditionals. This is probably harder to maintain and test, but something like this should work:
command: >-
command1
{{ if .Values.val2 }}
&& command2
{{ end }}
&& command3
The YAML >- syntax will cause everything indented after it to get folded into a single line, which helps the whitespace-control issues.
