用于构建Golang二进制文件的Docker映像

Question

I have a Go application that I build into a binary and distribute as a Docker image.

Currently, I'm using ubuntu as my base image, but this causes an issue where if a user tries to use a Timezone other than UTC or their local timezone, they get an error stating:

pod error: panic: open /usr/local/go/lib/time/zoneinfo.zip: no such file or directory

This error is caused because the LoadLocation package in Go requires that file.

I can think of two ways to fix this issue:

1. Continue using the ubuntu base image, but in my Dockerfile add the commands: RUN apt-get install -y tzdata

2. Use one of Golang's base images, eg. golang:1.7.5-alpine.

What would be the recommended way? I'm not sure if I need to or should be using a Golang image since this is the container where the pre-built binary runs. My understanding is that Golang images are good for building the binary in the first place.

Answer 1

This is more of a vote, but apt-get is what we (my company's tech group) do in situations like this. It gives us complete control over the hierarchy of images, but this is assuming you may have future images based on this one.
