Dockerizing a Go(lang) application is kinda similar to what we did with the Python one.
Prerequisites
- Docker
- Go(lang) application
Solution
Step 1. Create a Dockerfile in your Go(lang) project repository.
Step 2. Choose a base Docker image. As with Python, I go for the alpine versions. For instance:
FROM golang:alpine
Step 3. Set the working directory. Let’s call it /app.
WORKDIR /app
Step 4. Copy the current directory files.
COPY . ./
Step 5. Next, build main.
RUN go build -o main
Step 6. Finally, run the application code.
CMD ["/app/main.go"]
Step 7. Save the Dockerfile and start building the Docker image.
docker build -t sample-golang-app .
Step 8. Start the container.
docker run -p 8000:8000 sample-golang-app
Your containerized Go app should be accessible on http://localhost:8000.
