Top DevOps Interview Questions You Must Prepare In 2018

With the current surge in national economy the industrial traffic has increased many folds in terms of quantity of load and traffic volume. This results in early deterioration of the roads. Also the serviceability reduces hampering the industry’s supply of raw material and transport of finished goods. An efficient road transportation system is of vitally important for smooth operations of industrial units. Construction of new roads needs an enormous investment. However, once constructed the road network system requires huge resources to maintain serviceability and to ensure safe passage at an appropriate speed and with low VOC Vehicle Operating Cost. Road maintenance is therefore an essential function and should be carried out on a timely basis. The cost of providing and maintaining the roads for the industrial areas at an acceptable serviceability level is quite high. It is therefore essential for a transportation engineer to attempt establishing an acceptable pavement condition level from economic, safety and environmental point of view.

For this post, I have enabled Global Security, as it typical of most development environments. In larger development environments, authentication would normally be done against LDAP. Set up your own user and note their API Token. Since Global Security has been enabled, we will need the token later to trigger the Jenkins build from Git. The first job, the build job, will be responsible for pulling the source code from the Git Server.

So my HTTP POST request is reaching Hudson, but Hudson is complaining that there’s no jobs configured to do anything with this notification. According to the link above, I need to (a) set up SCM polling (any schedule is sufficient) and (b) allow anonymous read .

Sure, there are frameworks like Django , Rails or Seam to help you get sites built in record time with minimal resources, but at the same time applications are becoming more complex and more demanding. The frameworks help primarily with the initial effort of building the functionality of your site, but they are less useful addressing the longer-term problems associated with application development.

This article looks at one way of cracking the problem of regression testing retesting previously working parts of an application following a new build a modern web application, using two superb open source projects: What will you get out of this article? Our set-up achieves the following: It checks our Subversion repository every hour to see if anyone has committed any changes.

If they have, it updates the project from Subversion and builds it. It then creates a clean version of our application database, loads in reference data and deploys the application on our app server. A job is triggered that runs through a series of tests in a remotely-controlled web browser on the fresh application. Anything that deviates from the accepted norm is logged and screenshots of the web browser are taken.

Screenshots of the browser are also taken for key pages of the site for later checking by a human. If any of the tests fail, the developers responsible for the changes are notified by email of the problems. Our issue tracker is updated with any issues that were fixed in the build. For those applications that do need some form of scripting, Hudson offers relevant hooks in the build process to trigger these easily.

Configure Plugins The installed plugins also need to be configured. Add New Job Now, as the system is configured, we can add a new Jenkins job, which will update the checked out files from a SVN repository, build both the application under test and the Ranorex automation project, execute the application under test as well as the automation code and send a mail with the report file attached.

Start by creating a new item. Configure Source Code Management Next, we have to check out the source of both the application under test and our test automation project.

Setting the “Build Periodically” setting for a multibranch pipeline job implies that the job will be run at that interval. But the setting is intended to trigger periodic rescans of the repo, not periodic builds. The inline documentation implies that the build will be run periodically, as opposed to the branch indexing.

What is the most important thing DevOps helps us achieve? According to me, the most important thing that DevOps helps us achieve is to get the changes into production as quickly as possible while minimizing risks in software quality assurance and compliance. This is the primary objective of DevOps. For example, clearer communication and better working relationships between teams i. There are many industries that are using DevOps so you can mention any of those use cases, you can also refer the below example: Etsy is a peer-to-peer e-commerce website focused on handmade or vintage items and supplies, as well as unique factory-manufactured items.

Etsy struggled with slow, painful site updates that frequently caused the site to go down. With the help of a new technical management team, Etsy transitioned from its waterfall model, which produced four-hour full-site deployments twice weekly, to a more agile approach.
