You should add vips-dev package in RUN command.

[chenqing-yuhu]

RUN apk add --update --no-cache --repository http://dl-3.alpinelinux.org/alpine/edge/testing --repository http://dl-3.alpinelinux.org/alpine/edge/main vips-dev vips-poppler RUN apk add --no-cache poppler-dev

You should add dependency in Dockerfile, and add poppler to support pdf format

[BlackCodes]

you should export "export CGO_CFLAGS_ALLOW=-Xpreprocessor" when you use golang

[sanmiaohub]

apk add gcc g++ vips-dev vips-poppler pkgconf

export PKG_CONFIG_PATH=/usr/bin/pkgconf

Try RUN export CGO_CFLAGS_ALLOW=".*"

I got this:
