There was a problem hiding this comment.
From what I can see, this reader only admits a single-line json, which is very limiting. Instead, how about assuming first the input is json, try unmarhalling, and if that fails, fallback to using the yaml reader?
There was a problem hiding this comment.
The only reason we needed to be able to handle json input here at all is because we perform an uninject step before injecting and the uninject was producing json output when -o json was specified (which meant that we needed to handle json input during inject).
I've updated this so that the uninject that happens as a first step to inject will always produce yaml as its (intermediate) output so that we don't need to add json input support at all.

We add support for the
--output/-oflag inlinkerd injectandlinkerd uninjectcommands. The supported output formats are yaml (default) and json. Kubectl is able to accept both of these formats which means thatlinkerd injectandlinkerd uninjectoutput can be piped into kubectl regardless of which output format is used.
