Advanced Docker Training Course

Who should attend

This course is aimed at Software Developers and Systems Administrators who are looking to gain wider experience of the Docker ecosystem.

Prerequisites

Delegates should have attended our Microservices with Docker training course or have equivalent experience.

Live, instructor-led online and on-site training

We appreciate that you need flexibility to fit in with new working situations - whether you're an individual, part of a distributed team, or simply have projects and deadlines to meet.

Our remote training can take place online in a virtual classroom, with content split into modules to accommodate your scheduling challenges and meet your learning goals. Get in touch today to find out how we can help design a cost-effective, flexible training solution.

As soon as it's safe, we'll return to also offering the on-site custom training courses and programmes upon which we've built our reputation.
