问题
我遇到了一个问题，我试图在Docker中使用air运行我的Go Fiber项目，但是出现了以下错误：
uni-blog | /bin/sh: 1: /app/tmpmain.exe: not found
我使用的环境是：
- Windows 11
- Docker Desktop
- 最新的Golang版本
- air 1.27.10
- 最新的Fiber版本
这是我的docker-compose和Dockerfile：
docker-compose.yml：
# docker-compose up -d --build
version: "3.8"
services:
app:
container_name: uni-blog
image: app-dev
build:
context: .
target: development
volumes:
- ./:/app
ports:
- 3000:3000
Dockerfile：
FROM golang:1.17 as development
RUN apt update && apt upgrade -y && \
apt install -y git \
make openssh-client
RUN curl -fLo install.sh https://raw.githubusercontent.com/cosmtrek/air/master/install.sh \
&& chmod +x install.sh && sh install.sh && cp ./bin/air /bin/air
RUN air -v
WORKDIR /app
COPY go.mod go.sum ./
RUN go mod download
COPY . .
EXPOSE 3000
CMD air
我还尝试按照README中的说明安装air，但仍然出现这个错误。请帮忙看看。
提前感谢！

你的 volumes: 挂载替换了镜像中的 /app 目录，使用主机上的内容。如果二进制文件是在 Dockerfile 中构建的，那么这个 volumes: 挂载会隐藏它；如果你在主机上的相同位置没有匹配的兼容二进制文件，你会得到一个类似你所看到的错误。
我建议移除这个 volumes: 块，这样你就可以运行镜像中内置的二进制文件了。docker-compose.yml 文件可以简化为以下内容：
version: '3.8'
services:
app:
build: .
ports:
- '3000:3000'
英文:
The volumes: mount you have replaces the /app directory in the image with content from the host. If the binary is built in the Dockerfile, that volumes: mount hides it; if you don't have a matching compatible binary on the host in the same place, you'll get an error like what you see.
I'd remove that volumes: block so you're actually running the binary that's built into the image. The docker-compose.yml file can be reduced to as little as:
version: '3.8'
services:
app:
build: .
ports:
- '3000:3000'

如果你看一下错误信息，你会注意到在 tmp/main.exe 之间有一个拼写错误：
/bin/sh: 1: /app/tmpmain.exe: not found
这个错误来自于 .air.toml 配置文件：
bin = "tmp\\main.exe"
在项目根目录下创建 .air.toml 文件，内容如下：
root = "."
tmp_dir = "tmp"
[build]
# 构建可执行文件
cmd = "go build -o ./tmp/main.exe ."
# 读取可执行文件
bin = "tmp/main.exe"
# 监听这些文件的变化
include_ext = ["go", "yml"]
# 忽略这些文件的变化
exclude_dir = ["tmp"]
# 防止构建触发得太快
delay = 1000 # 毫秒
[misc]
clean_on_exit = true
英文:
If you look the error, you ca notice there is a typo between tmp/main.exe:
/bin/sh: 1: /app/tmpmain.exe: not found
This is coming from .air.toml config file:
bin = "tmp\\main.exe"
Create .air.toml file in project root like so:
root = "."
tmp_dir = "tmp"
[build]
# Build binary.
cmd = "go build -o ./tmp/main.exe ."
# Read binary.
bin = "tmp/main.exe"
# Watch changes in those files
include_ext = [ "go", "yml"]
# Ignore changes in these files
exclude_dir = ["tmp"]
# Stop builds from triggering too fast
delay = 1000 # ms
[misc]
clean_on_exit = true
