Live reloading with air (docker)

Yesterday, we saw how we can use the air-verse package to live reload the code. Today, let’s do the same using docker.

main.go

package main

import "fmt"

func main() {
	fmt.Println("Bonjour, le monde!")
}

Create a container from the image cosmtrek/air with the working directory set to the current directory. Air will watch this directory.

docker run -it --rm \
    -w "/home/me/airverse" \
    -v $(pwd):/home/me/airverse \
    -p 9090:9090 \
    cosmtrek/air;
