create a google cloud run service in go

To create a Google Cloud Run service in Go, follow these steps:

  1. Write your Go code and create a Dockerfile to package your code in a container.

Here's an example Dockerfile:

# Use the official Golang image as the parent image
FROM golang:1.16-alpine

# Set the current working directory inside the container
WORKDIR /app

# Copy the Go module files into the container
COPY go.mod go.sum ./

# Download and install Go dependencies
RUN go mod download

# Copy the rest of the application code into the container
COPY . .

# Build the Go application
RUN go build -o app

# Expose port 8080 to the outside world
EXPOSE 8080

# Set the default command to run the Go application
CMD ["./app"]

  1. Build the Docker image by running the following command in the directory containing your Dockerfile:
docker build -t my-golang-app .

2 lines
  1. Push the Docker image to Google Container Registry by tagging it with the fully qualified name (including the project ID) of your Cloud Run service:
docker tag my-golang-app gcr.io/my-project/my-golang-app
docker push gcr.io/my-project/my-golang-app

  1. Deploy the container to Cloud Run using the command line interface:
gcloud run deploy my-golang-service \
    --image gcr.io/my-project/my-golang-app \
    --platform managed \
    --port 8080 \
    --region us-central1
152 chars
6 lines

This will deploy your Go application as a Cloud Run service, ready to receive HTTP requests.

You can find more information about deploying to Cloud Run in the official documentation: https://cloud.google.com/run/docs/quickstarts/build-and-deploy#go
