go - 如何创建包含 zoneinfo.zip 的二进制文件

Question

我正在使用 Docker 创建容器应用程序，然后将其部署到 kubernetes engine但是当应用程序被初始化时，我得到这个错误:

err: open C:\Go/lib/time/zoneinfo.zip: no such file or directory

Answer 1

您可能会考虑构建您的 Go 应用程序 with Go 1.15 (2020 年 8 月，两年后)

New embedded tzdata package

Go 1.15 includes a new package, time/tzdata, that permits embedding the timezone database into a program.

• Importing this package (as import _ "time/tzdata") permits the program to find timezone information even if the timezone database is not available on the local system.
• You can also embed the timezone database by building with -tags timetzdata.

Either approach increases the size of the program by about 800 KB.

这样，一旦作为 Docker 镜像部署到 Kubernetes 引擎，它就不必尝试加载任何时区信息，因为这些信息已嵌入其程序中。

注意:如commented通过 dolmen :

This solution has the drawback that the timezone information version is linked to the version of Go you use for building.

If you keep using a fixed version of Go for your project, you will keep timezones from that version.

Being able to update the timezone information independently from the Go version (update every time you rebuild the Docker image for deploy) might be a better choice.
