As a base we’ll be using the official Golang Alpine Linux image for Docker, but we’ll be customizing it.

At runtime we are executing the installed application. The first pull command does the job of retrieving the redis image from DockerHub so that we can then run it as a container using the second command. In the second command we specify the name of our redis container and we also map our local port 6379 to the port that redis is running against within the container using the -p flag.. Connecting to our Redis Instance When you use the golang image, Docker expands that to golang:latest, which (as you might guess) will map to the latest version available on the Docker Hub. If you want to use a specific version of Go, that’s very easy: specify that version as a tag after the image name.
