[DOCKER] Could not import C error in GO environment

Error occurred

A mysterious error when trying to update the schema with gqlgen in Go's graphql library

/go/src # go run github.com/99designs/gqlgen
validation failed: packages.Load: /usr/local/go/src/net/cgo_linux.go:12:8: could not import C (no metadata for C)
exit status 1

Solution

Apparently gcc is not on the docker image. Maybe this? Https://github.com/golangci/golangci-lint/issues/602

After updating the apk with apk update, I put in a build package called alpine-sdk and it worked. Regarding apk, this article was easy to understand.

/go/src # apk update
fetch http://dl-cdn.alpinelinux.org/alpine/v3.12/main/x86_64/APKINDEX.tar.gz

fetch http://dl-cdn.alpinelinux.org/alpine/v3.12/community/x86_64/APKINDEX.tar.gz
