Unable to merge dictionaries from different files

[littlebigfab]

Hello,

When loading multiple values files containing the same key name but different contents, running helm install merges the dictionaries, but the helm-ssm plugin does not.

How to reproduce:

• file1.yml

key1:
  value1: foo
  value2: bar

• file2.yml

key1:
  value3: biz

• Install a helm chart with the ssm plugin on, loading the two values files:

helm ssm install -f file1.yml -f file2.yml [NAME] [CHART]

Expected:

The following dictionary is loaded into the helm chart:

key1:
  value1: foo
  value2: bar
  value3: biz

Actual result:

Only the dictionary contained in file2.yaml is actually loaded into the helm chart:

key1:
  value3: biz
