There are many online DevOps training programs offered by many institutes like Edureka, Udemy, Intellipath, etc
Edureka DevOps Course (Experienced professional, provides demos, good quality course material, also provides 24*7 support for any queries)
Udemy DevOps course (Udemy provides only recorded videos, not realtime online training by the instructor.)
Intellipath DevOps Training (the customer reviews of Intellipath is not good, so its ur personal choice to go with it or not)
Personally, I found Edureka's DevOps Online training course to be the best as I got to learn about popular DevOps tools like Git, Jenkins, Docker, Ansible, Puppet, Kubernetes, and Nagios.
Edureka's DevOps training is a hands-on wherein you will be exposed to real-time scenarios in the software development process which are not covered by other course providers.
Edureka provides a good list of Tutorial videos. I would recommend you to go through this tutorial video playlist as well as blog series.
