In this post on “How To Become A DevOps Engineer”, I will be giving you a complete roadmap that will set you on the path of becoming a successful DevOps engineer.
But, who is a DevOps Engineer?
Well, DevOps Engineer is somebody who understands the Software Development Lifecycle and has the outright understanding of various automation tools for developing digital pipelines (CI/ CD pipelines).
Still wondering who is a DevOps Engineer? I have a dedicated post on DevOps Engineer roles and responsibilities, go ahead and check it out, and let me know your thoughts about it.
Now the question is, who can become a DevOps Engineer?
If you are a Developer, or an Ops person, or a Quality Assurance guy, or even if you are a fresher you can become a DevOps Engineer. But, let me tell you it will be a pretty long journey if you want to call yourself a DevOps guy :)
I would definitely recommend a Structured Training DevOps Program because it is not only about the theoretical knowledge, it is more about the hands-on knowledge. You require proper infrastructure to perform such practicals. Also, a DevOps Engineer is not a person who just understand various tools. It is more about how and where you can use various Development, Testing and Deployment technologies to get the maximum benefit (Architecting an SDLC Solution).
Now I will start this post, on How To Become A DevOps Engineer?
Let’s begin this journey, by listing down some important skills that organizations look for in a DevOps Engineer:
Consider the following road-map:
1. Source Code Management Skills (Version Control System):
Be proficient with at least one version control/ source code management tool, preferably Git, you should have good hands-on knowledge of Git and Git workflows.
Once you know Git, the next step is to understand how you can automate the build process, how you can continuously build the latest commit to the source code repository. For that, you should understand how automation servers like Jenkins work. Basically, how you can integrate Build tools like Maven with Source code Management tools like Git. This process is termed as Continuous Integration. Yes, I am talking about developing Continuous Integration pipeline.
Next step is to learn how you can automate testing stage, also how you can make it less complex because I believe you all have faced problems like the code works fine in the dev environment but not in the test environment. You must understand how you can replicate the Dev environment in your testing servers. For this, you should understand how tools like Puppet, Chef etc. work, you can also use Docker containers for this purpose, so I would say learning Docker is a must. Also, you must learn how you can continuously test your code after every commit. You again need to integrate Automation testing tools like Selenium with Jenkins. This is termed as Continuous Delivery.
Finally, you should understand how you can safely deploy the application in the production server. Again, you need tools like Puppet or Docker to configure and deploy it in the prod environment.
Also, it is very important for a DevOps Engineer to collect feedback and implement the changes quickly, for that you should have knowledge of monitoring tools like Nagios, Splunk etc.
Along with all these things you should have good cloud knowledge to combine the befits of Cloud and DevOps. Most of the organizations have their infrastructure on Cloud, so it is a must learn skill.
Who said becoming a DevOps Engineer is a cake walk. But, we all know “no pain no gain” :)
Now the question is from where you can acquire the above-mentioned skills.
As I mentioned above to get the theoretical knowledge you can check the official website of all the major DevOps tools. But, that is not enough to get a DevOps job, you should have hands-on knowledge. For that, you need to work on projects, which might be there in your organization. If not, you can also consider the projects provided by edureka!, it will include all the stages involved in DevOps and also include all the major DevOps tools.
