I am using kubectl create configmap command as follows:
kubectl create configmap config-multi-yaml-files --from-file=templates/1template.yaml --from-file=apps/app1.yaml --from-file=app2/app2.yaml --dry-run=true -o yaml > output.yaml
The resultant configmap do have file names (app1.yaml, app2.yaml) like this:
apiVersion: v1
data:
app1.yaml: |-
groups:
- name: sample
rules:
- alert: alert
How can I use this command so that I do have a configmap from multiple yamls, but do not have the respective file names in the resultant configmap.
Any pointers are appreciated.
Thanks.
Unfortunately, you will have to use keys in order to make it work. But here is an example of what you could do:
kubectl create configmap config-multi-yaml-files --from-file <(cat templates/1template.yaml) --from-file <(cat apps/app1.yaml) --dry-run=client -o yaml
That way the keys would be numbers: 11, 12, 13...
So you will not have to use file names in your ConfigMap but keys will have to be used.
