How to Resolve the \'Import Path Does Not Begin with Hostname\' Error During Docker Build?

Error Resolution: 'Import Path Does Not Begin with Hostname' in Docker Build

When building a Docker image with a local package, you may encounter the error 'import path does not begin with hostname.' This issue arises due to the need for your dependencies to be accessible within the Docker container during the build process.

The commonly used Dockerfile for simple cases is FROM golang:onbuild. However, this image type does not automatically fetch dependencies.

To resolve the error, you can create a custom Dockerfile outlining the necessary steps for building your application. An example Dockerfile that addresses this issue is:

FROM golang:1.6
ADD . /go/src/yourapplication
RUN go get github.com/jadekler/git-go-websiteskeleton
RUN go install yourapplication
ENTRYPOINT /go/bin/yourapplication
EXPOSE 8080

This Dockerfile adds your source code and the required dependency to the container. It then builds the application, starts it, and exposes it on port 8080. By customizing the Dockerfile in this manner, you can successfully build your Docker image with local dependencies without encountering the 'import path does not begin with hostname' error.
