create a google cloud run service in go in go

To create a Google Cloud Run service in Go, you will need to follow these steps:

1. Write your Go program to implement your server logic. An example code for a simple HTTP server in Go is:

   main.go
   package main
   
   import (
     "fmt"
     "log"
     "net/http"
   )
   
   func handler(w http.ResponseWriter, r *http.Request) {
     fmt.Fprintf(w, "Hello from Go!")
   }
   
   func main() {
     http.HandleFunc("/", handler)
     log.Fatal(http.ListenAndServe(":8080", nil))
   }

   17 lines

2. Create a Dockerfile for your Go program. An example Dockerfile is:

   # Use the official Go image as the parent image
   FROM golang:1.16
   
   # Set the working directory inside the container
   WORKDIR /app
   
   # Copy the necessary files to the container
   COPY go.mod ./
   COPY go.sum ./
   RUN go mod download
   COPY . .
   
   # Build the Go program inside the container
   RUN CGO_ENABLED=0 GOOS=linux go build -a -installsuffix cgo -o main .
   
   # Use a minimal base image to package the Go program
   FROM alpine:latest
   RUN apk --no-cache add ca-certificates
   WORKDIR /root/
   COPY --from=0 /app/main .
   
   # Set the command to run when the container starts
   CMD ["./main"]

   24 lines

3. Build a Docker image of your Go program by running the following command in the same directory as the Dockerfile:

   docker build -t [IMAGE_NAME] .
   31 chars
   2 lines

4. Push the Docker image to a container registry, such as Google Container Registry or Docker Hub:

   docker push [IMAGE_NAME]
   25 chars
   2 lines

5. Deploy the Docker image to Cloud Run using the following command:

   gcloud run deploy --image [IMAGE_NAME] --platform managed --region [REGION] --allow-unauthenticated [SERVICE_NAME]
   115 chars
   2 lines

   Replace [IMAGE_NAME] with the name of the Docker image that you pushed to the container registry, [REGION] with the region where you want to deploy the service, and [SERVICE_NAME] with a name that you choose for your service.

   Once the deployment is complete, you can access your service by navigating to the URL provided in the output of the command.
