Overview of this book

No doubt Docker Containers are the future of highly-scalable software systems and have cost and runtime efficient supporting infrastructure. But learning it might look complex as it comes with many technicalities. This is where The Docker Workshop will help you. Through this workshop, you’ll quickly learn how to work with containers and Docker with the help of practical activities.? The workshop starts with Docker containers, enabling you to understand how it works. You’ll run third party Docker images and also create your own images using Dockerfiles and multi-stage Dockerfiles. Next, you’ll create environments for Docker images, and expedite your deployment and testing process with Continuous Integration. Moving ahead, you’ll tap into interesting topics and learn how to implement production-ready environments using Docker Swarm. You’ll also apply best practices to secure Docker images and to ensure that production environments are running at maximum capacity. Towards the end, you’ll gather skills to successfully move Docker from development to testing, and then into production. While doing so, you’ll learn how to troubleshoot issues, clear up resource bottlenecks and optimize the performance of services. By the end of this workshop, you’ll be able to utilize Docker containers in real-world use cases.

15. Extending Docker with Plugins

Activity 15.01: Installing WordPress with Network and Volume Plugins


It is possible to create containers for the database and the WordPress blog using volume and networking plugins with the following steps:

  1. Create a network with the following command:
    docker network create  \
    --driver=store/weaveworks/net-plugin:2.5.2 \
    --attachable \

    This command creates a network using the Weave Net plugin, specified with the driver flag. In addition, the volume is specified as attachable, which means you can connect to Docker containers in the future. Finally, the name of the container will be wp-network. You should get output like the following:

  2. Create a volume with the following command:
    docker volume create -d vieux/sshfs \
    --name wp-content \
    -o sshcmd=root@localhost:/tmp \
    -o password=root \
    -o port=2222

    This command creates a volume over SSH using the vieux/sshfs plugin. The name of the volume is wp...
