The
coder_metadataresource is only used to apply metadata to specific template resources. To apply metadata at the workspace level, and have it be shown on the main workspace pane, ametadatablock needs to be created on thecoder_agentresource. Alternatively, anycoder_metadataattached to the resource containing the agent will be shown on the dashboard by default (see our dogfood template), but this isn't super obvious, so we'll add a comment.It's pretty easy to assume that the
coder_metadataresource would let you apply workspace metadata, if you associated it with the agent, so we'll also add a comment mentioning this isn't the case.
