This course stands out by connecting two skills every DevOps and cloud professional need, through 10 real-world demos: reliable communication and safe data management. You'll learn how containers talk to each other, how Docker networks support real applications, and how volumes and bind mounts prevent data loss. It's also part of the larger Docker Certified Associate Preparation specialization, which includes 70+ real-world demos and a full mock exam across all seven courses.

You'll work with Docker networks, custom bridge networks, overlay networks, DNS and service discovery, Docker volumes, bind mounts, and the Overlay2 storage driver. By learning these tools and features, you'll be able to connect containers, manage persistent data, troubleshoot communication issues, and protect application data in real Docker environments.

To access course materials, assignments, and earn a Certificate, you'll need to purchase the Certificate experience when you enroll in a course. Eligible learners may also have the option to start with a Free Trial. Some courses may also offer a Full Course, No Certificate option. This lets you access course materials, submit required assessments, and receive a final grade, but you won't be able to earn or purchase a Certificate.

When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.
