Build Docker image

[billziss-gh]

It is not clear to me what you are asking.

If you are looking for cross-compilation builds it is best to use xgo as documented here.

If you are looking to create your own Docker image to build cgofuse based projects then you need to install the prerequisites and then build as documented here.

[tomcat-bit]

To explain better -- I'm using the current Docker file

FROM golang:alpine AS builder
ENV GOBIN $GOPATH/bin
RUN apk update
RUN apk add fuse-dev gcc libc-dev fuse

# Set necessary environmet variables needed for our image
ENV GO111MODULE=auto \
    CGO_ENABLED=0 \
    GOOS=linux \
    GOARCH=amd64

RUN mkdir -p /go/src/github.com/tomcat-bit/cgofuse
WORKDIR /go/src/github.com/tomcat-bit/cgofuse

COPY go.mod .
COPY go.sum .
RUN go mod download 

COPY . .

RUN go build -a -o /fuser ./examples/passthrough
FROM alpine:latest

RUN apk update
RUN apk add fuse
COPY --from=builder /fuser /

I get

/go/pkg/mod/github.com/billziss-gh/[email protected]/fuse/host.go:30:8: undefined: c_struct_fuse

It seems like using Go mod doesn't work with building with fuse. Further, using dep as described in andersjohansenange@a08ea76 works fine. When it works, I'll probably make a pull request on how to build a Docker image when Go modules is enabled.
