所以我想在 cloud run 中部署我的简单 go 后端。我使用 gin 来处理路由。我处理它的主要函数如下所示:
func main() { r := gin.default() r.get("/api/health", handlers.healthcheckhandler()) r.post("/questions", handlers.createquestionhandler(client)) r.get("/questions/:level", handlers.getallquestionhandler(client)) r.run("0.0.0.0:8080") }
我尝试使用 docker 构建它并且成功了。我的 dockerfile 如下所示:
from golang:1.20 env gin_mode=release workdir /app # download go modules copy go.mod go.sum ./ run go mod download copy . . # build run go build -o /docker-api expose 8080 # run cmd ["/docker-api"]
所以我尝试在 google cloud cli 中使用 docker run 来运行它,它似乎运行得很好:
docker run -p 8080:8080 gcr.io/matharc/math-arc-api [gin-debug] [warning] creating an engine instance with the logger and recovery middleware already attached. [gin-debug] [warning] running in "debug" mode. switch to "release" mode in production. - using env: export gin_mode=release - using code: gin.setmode(gin.releasemode) [gin-debug] get /api/health --> matharc.com/m/handlers.healthcheckhandler.func1 (3 handlers) [gin-debug] post /questions --> matharc.com/m/handlers.createquestionhandler.func1 (3 handlers) [gin-debug] get /questions/:level --> matharc.com/m/handlers.getallquestionhandler.func1 (3 handlers) [gin-debug] [warning] you trusted all proxies, this is not safe. we recommend you to set a value. please check https://pkg.go.dev/github.com/gin-gonic/gin#readme-don-t-trust-all-proxies for details. [gin-debug] listening and serving http on localhost:8080
但是当我尝试在端口 8080 上预览它时,我无法访问它:
我尝试将其部署在 cloud run 中,但毫不奇怪,它不起作用。我得到:
STARTUP HTTP probe failed 1 time consecutively for container "math-arc-api-1" on path "/api/health". The instance was not started.
我做错了什么?
所以评论中 @Hans Kilian 的答案是正确的。问题是因为我使用 localhost 而不是 0.0.0.0
。我以为我已经在代码中将其更改为 0.0.0.0
但似乎我在构建它时犯了一些错误。
