Troubleshooting "Cannot Find Package" Error in Docker with Go App
When building a Docker image for a Go application, it's common to encounter the "cannot find package" error. This can occur if the Go code is not structured correctly within the image or if dependencies are not properly installed.
Problem:
In a Dockerfile, if you're copying all files to the root directory, attempting to build the application there, and then expecting the binary to exist in "/go/bin/app," but it's not there, this error can arise.
Solution:
To resolve this issue, modify the Dockerfile to include the following steps:
Copy project files to "/go/src/myapp":
ADD . /go/src/myapp
Set the working directory to "/go/src/myapp":
WORKDIR /go/src/myapp
Install dependencies:
RUN go get myapp
Install/build the binary:
RUN go install
Set the entry point:
ENTRYPOINT ["/go/bin/myapp"]
