我有一个Golang Fiber服务器，在Google Cloud Run上运行时会自动退出，并显示以下消息：
Container called exit(0).我使用以下Dockerfile运行它
# Use the offical golang image to create a binary.
FROM golang:buster as builder
# Create and change to the app directory.
WORKDIR /app
# Retrieve application dependencies.
COPY go.mod ./
COPY go.sum ./
RUN go mod download
COPY . ./
RUN go build
# Use the official Debian slim image for a lean production container.
# https://hub.docker.com/_/debian
# https://docs.docker.com/develop/develop-images/multistage-build/#use-multi-stage- builds
FROM debian:buster-slim
RUN set -x && apt-get update && DEBIAN_FRONTEND=noninteractive apt-get install -y \
ca-certificates && \
rm -rf /var/lib/apt/lists/*
# Copy the binary to the production image from the builder stage.
COPY --from=builder /app/redirect-middleware.git /app/
COPY --from=builder /app/pkg /app/pkg/
EXPOSE 8080
# Run the web service on container startup.
CMD ["/app/redirect-middleware.git", "dev"]main.go（only func main（））
func main() {
// Load env config
c, err := config.LoadConfig()
if err != nil {
log.Fatalln("Failed at config", err)
}
// init DB
db.InitDb()
// init fiber API
app := fiber.New()
log.Print("Started new Fiber app...")
// initial route sending version of API
app.Get("/", func(c *fiber.Ctx) error {
return c.SendString(fmt.Sprintf("Redirection middleware - v%s", viper.Get("Version").(string)))
})
log.Print("Default root route set...")
// api routes
api := app.Group("/api") // /api
v1 := api.Group("/v1") // /api/v1
log.Print("api/v1 group set...")
// register routes v1
mastermenus.RegisterRoutes(v1)
log.Print("Route registered...")
app.Listen(c.Port)
log.Print("Api started listening in port 8080")
}最后一行在Google Cloud Run日志中执行得很好，我可以看到Api started listening in port 8080。
为什么我的容器单独退出？它应该启动Fiber API。

我发现了这个问题。在我的
stage.env文件中，我已经将端口设置为:8080。在本地，传递app.Listen(c.Port)可以按照预期转换为app.Listen(":8080")。在Cloud Run中使用时，这被转换为app.Listen("8080")，当然不起作用，因为它认为这是主机而不是端口。我添加了
app.Listen(":" + c.Port)，它可以工作。如果您遇到这种情况，请捕获错误：
并采取相应的行动。
