Merging into an Empty file

[abdiriman]

I've got two Yml files which hypothetically are example.yml and example2.yml.

The example.yml file has

ES:
port: port

The example2.yml file is empty.

I am trying to merge the contents of example.yml into example2.yml file which is empty.

The command I am running is yq m -i example2.yml example.yml

Error I get: Error: asked to process document index 0 but there are only 0 document(s)

Also how would i install your version of yq correctly in a docker-file? I noticed there is a-lot of versions of "yq" out there.

yq has prebuilt docker image, or you can build your own. Take a look at the Dockerfile in github

Done! https://github.com/mikefarah/yq/releases/tag/3.1.0
