Timezone issue in Go and Docker

Issue

time.In(loc) raises issue running in Docker container

panic: time: missing Location in call to Time.In

goroutine 1 [running]:
time.Time.In(...)

main.main()
        /go/src/go-docker-timezone/main.go:14 +0x21a

Cause

Solution

Copy timezone information from tzdata package to container (used to run binary file). Refer to Docker file for detail.

$ docker build -t gotz .
# Run docker image
$ docker run gotz
