create a webserver and deploy to cloud run in go

To create a Go web server, you can use the built-in net/http package. Here's an example code snippet:

main.go
package main

import (
	"fmt"
	"net/http"
)

func main() {
	// Define the request handler function.
	handler := func(w http.ResponseWriter, r *http.Request) {
		fmt.Fprintf(w, "Hello, World!")
	}

	// Start the web server and listen for incoming requests.
	if err := http.ListenAndServe(":8080", http.HandlerFunc(handler)); err != nil {
		fmt.Println(err)
	}
}

Next, to deploy the web server to Cloud Run, you can follow these steps:

1. Build a container image for your web server using a Dockerfile. Here's a sample Dockerfile:

   main.go
   FROM golang:1.16
   
   WORKDIR /app
   
   COPY . .
   
   RUN go build -o server .
   
   EXPOSE 8080
   
   CMD ["./server"]
   98 chars
   12 lines

   This Dockerfile uses Go version 1.16 as the base image, copies the current directory into the container, builds the web server and exposes port 8080.

2. Push the container image to a container registry. For example, you can use Google Cloud Container Registry (GCR) by running:

   main.go
   gcloud builds submit --tag gcr.io/PROJECT_ID/server
   52 chars
   2 lines

   Replace PROJECT_ID with your actual GCP Project ID.

3. Deploy the container image to Cloud Run. Run the following command:

   main.go
   gcloud run deploy --image gcr.io/PROJECT_ID/server --platform managed
   70 chars
   2 lines

   Replace PROJECT_ID with your actual GCP Project ID.

That's it! Your Go web server is now deployed to Cloud Run and can be accessed at the URL provided by the gcloud run deploy command.
