在 Docker 中获取和运行 Go 库的方法

小伙伴们有没有觉得学习Golang很有意思？有意思就对了！今天就给大家带来《在 Docker 中获取和运行 Go 库的方法》，以下内容将会涉及到，若是在学习中对其中部分知识点有疑问，或许看了本文就能帮到你！

我有这个简单的 dockerfile：

from golang:1.16.6-buster
run wget -o - -q https://raw.githubusercontent.com/golangci/golangci-lint/master/install.sh | sh -s v1.45.2
run golangci-lint --version

当我构建它时，无论我如何更改上面的第二行，我总是得到：

> [3/3] run golangci-lint --version:
#6 0.331 /bin/sh: 1: golangci-lint: not found

我到底做错了什么？

如果我尝试：

from golang:1.16.6-buster
run curl -s https://raw.githubusercontent.com/golangci/golangci-lint/master/install.sh\
    | sh -s v1.45.2

run bin/golangci-lint version

我得到了详细的输出：

正确答案

golangci-lint 位于 bin 目录中：

from golang:1.16.6-buster

run curl -s https://raw.githubusercontent.com/golangci/golangci-lint/master/install.sh\
    | sh -s v1.45.2
run pwd
#run /go/bin/golangci-lint --version

构建输出：
