a lightweight and portable command-line YAML, JSON and XML processor. yq uses jq like syntax but works with yaml files as well as json, xml, properties, csv and tsv. It doesn’t yet support everything jq does – but it does support the most common operations and functions, and more is being added continuously.

And to write to a root file you can either use sponge:
or write to a temporary file:
Note that you can run yq in docker without network access and other privileges if you desire, namely -security-opt=no-new-privileges -cap-drop all -network none.
You’ll need to pass the -i-interactive flag to docker:
It can be useful to have a bash function to avoid typing the whole docker command:
yq’s container image no longer runs under root (#860). If you’d like to install more things in the container image, or you’re having permissions issues when attempting to read/write files you’ll need to either:
Or, in your Dockerfile:
By default, the alpine image yq uses does not include timezone data. If you’d like to use the tz operator, you’ll need to include this data:
