我如何知道哪个版本的依赖项被拉出？

In main.go I have this import statement:

import (
    "fmt"
    "log"
    "os"
    "os/signal"
    "strings"
    "syscall"
    "github.com/bwmarrin/discordgo"
)

And I'm running into a bug that is supposed to be fixed in the more recent versions of this dependency. How can I determine what version was pulled in when I built my docker container that I deployed?

In GoLand it doesn't show any external dependencies:

Here's my Dockerfile:

FROM golang:1.12-alpine
RUN mkdir /app
WORKDIR /app
ADD src/ /app

ENV CGO_ENABLED=0
ENV GO111MODULE=off

# Fetch application dependencies
RUN apk add --no-cache --update git \
    && go get github.com/bwmarrin/discordgo \
    && go get github.com/jonas747/dshardmanager \
    && go get github.com/bugsnag/bugsnag-go \
    && apk del git

# Build binary
RUN go build -o main .

CMD ["/app/main"]

There's a couple ways you can go about this. When you run go get remote/path/to/lib, it installs that to $GOPATH/src/remote/path/to/lib, so if you cd into that path and run git describe --tags, you'll see the latest version pulled. However, if you manage your project with go modules, you should be able to see the version you're using in the go.mod file after the dependency name.

So, in essence: go get github.com/bwmarrin/discordgo && cd $GOPATH/src/github.com/bwmarrin/discordgo && git describe --tags should be the quick and dirty way to find what version you're using for this specific scenario.

If you want an updated version of your package try using go get -u <package>

Or maybe use dependency management such as dep. (https://github.com/golang/dep) You can specify your versions in your Gopkg.toml.

Or go modules if you are using version 1.11 or higher for golang.

I see your GoLand SDK is in different version with your Docker. If you use 1.12, you can try to use go module. It will generate a file go.mod, which will describe your package and version, and better management. For example:

module github.com/example

require (
    github.com/Azure/azure-storage-blob-go v0.0.0-20190104215108-45d0c5e3638e
