I have an init container and am running a command in it which takes a ton of parameters so I have something like
command: ['sh', '-c', 'tool input1 input2 output
-action param1 -action param2 -action param3 -action param4 -action param5 -action param6 -action param7 -action param7 -action param8 -action param9 -action param10 ']This highly decreases the readability of the command. Is there someway I can improve this like passsing this a a separate array ?
You can make command's args as a YAML list:
initContainers:
- name: init-container
image: busybox:1.28
command: ["/bin/sh","-c"]
args:
- -action
- param1
- -action
- param2
.
.
.
Another tip is to do it via command, so save your time that you needn't manually do that.
kubectl run nginx --image=nginx --generator=run-pod/v1 --dry-run -o yaml -- tool input1 input2 output -action param1 -action param2 -action param3 -action param4 -action param5 -action param6 -action param7 -action param7 -action param8 -action param9 -action param10
apiVersion: v1
kind: Pod
metadata:
creationTimestamp: null
labels:
run: nginx
name: nginx
spec:
containers:
- args:
- tool
- input1
- input2
- output
- -action
- param1
- -action
- param2
- -action
- param3
- -action
- param4
- -action
- param5
- -action
- param6
- -action
- param7
- -action
- param7
- -action
- param8
- -action
- param9
- -action
- param10
image: nginx
name: nginx
resources: {}
dnsPolicy: ClusterFirst
restartPolicy: Always
status: {}
Above dry-run command will generate the yaml for option --args, you copy & paste it into the part of original init container, make it so simple and you can do it less in one munite
You still need keep the part of command, don't forget
command: ["/bin/sh","-c"]
