Building images using APIs

In the previous recipe, we explored a few actions on Docker images using APIs. In this recipe, we will build a Docker image using the /build API. Here is the /build API snippet from Swagger Editor:

How to do it...

1. Begin by cloning the https://github.com/docker-cookbook/apache2 repository, as follows:

$ git clone https://github.com/docker-cookbook/apache2 

This repository contains the Dockerfile to bundle an apache2 service; listed here is the content of the Dockerfile:

2. Let's create the build context by bundling the content of the cloned apache2 repository as a tar file, as demonstrated here:

$ cd apache2$ tar cvf /tmp/apache2.tar * 

3. Continue on to build the Docker image using the /build API:

$ curl -X POST \       -H "Content-Type:application/tar" \       --data-binary '@/tmp/apache2.tar' \       --unix-socket /var/run/docker.sock \        http:/build

While the build is in progress, you will receive the build logs as a series of JSON messages. Once the build is successfully...
