What is Release Orchestration?

Release orchestration is a process that coordinates, plans, and organizes automated tasks executed by numerous systems, updating them for users and various environments such as testing, production, and staging. It also helps reduce risks and ensures high-quality outcomes.

Throughout the process, release orchestration may also involve planning, including clarifying the scope of the release, organizing release dates, and coordinating activities with team members and stakeholders involved in the release process.

One of the main purposes of release orchestration is to make software releases efficient, reliable, and predictable. It ensures that new updates and features in the software product are delivered in a controlled manner, providing a positive user experience.

CI/CD Tools Comparison

Shiwani Sharma — Fri, 08 Mar 2024 02:48:43 +0000

What is CI/CD?

CI and CD stand for continuous integration (CI) and continuous delivery (CD).

The main target of both the tools is desktop applications and now web and cloud services. A mixture of two software developments is called continuous integration and continuous delivery. Both are useful in software for the automation which facilitates the differences in code incremental to transmit quickly and that is beneficial for the production from the user’s desktops.

It is a process where the commodity gets on the market quickly and from the production, the code is continuously delivered, new characteristics come with the profitable procedure of delivery.

While writing a code, a developer doing practice is CI and doing the practice done after the code is completed is CD. In CI the code is created, planning and then testing is continuous whereas in CD for testing and development it transmits the code automatically. For enhancing your or

Continuous Delivery (CD) consists of many things for the user into the production of such as some new features , bug fixes, configuration changes etc.

Some stages of CI/CD pipelines are as follow:

Why is CI/CD important ?

By discussing some key point you will get to know why CI/CD is important. So let’s discuss the points below.

Cost Decreases

It saves the developer time and reduces the number of errors by this the developer can invest their time on product development. As we know this tool has less code that if they find any error caught on a quick basis and increasing the quality of code also increases your ROI.

Provides Customer Satisfaction

CI/CD is important because it increases the size of the organization by providing all the needs of the customer and satisfies them. In the first opinion, a new customer converted into a long term satisfied customer. This tool gives new features, bug fixes and with time rises new technology will also be updated.

Quicker (MTTR) Mean Time To Resolution

A new feature will be updated so it is important to take care of the old features. Rebuilding of a damaged feature with the set of average time and estimates the maintainability of repairable features is MTTR.

Delivered The Best Code Quality

CI/CD is important because it improves the code quality, as it permits the use of a small amount of code at a particular time. These codes are easy to handle and if any type of issues come, they can be overhauled soon at a later date.

Decreased Backlog

In the development process, the backlog of non-critical defects is quieter because the other features arise and the defects are stabilized.

CI/CD Tools

Some of the most popular CI/CD tools are as follow:

Jenkins
TeamCity
Circle CI
Codeship

There are many tools in CI/CD , but we have mention few important and very popular are as follow:

The best popular Jenkins Plugins to have in 2024

Sun, 03 Mar 2024 14:05:07 +0000

Must Have Jenkins Plugins in 2024

Jenkins and DevOps go hand-in-hand and to make the CI/CD process a cakewalk the former provides a plethora of Plugins. To get the maximum advantage of Jenkins we need to know how and when to use the plug-in.

Let’s see how Jenkins plug-in makes the life easier for a DevOps engineer.

How does Jenkins work?

The DevOps has solved the most critical problem of application integration. The process of integration without any automation tool was really cumbersome and the most tedious part. But with Jenkins, the same process is no more a nightmare. Let’s have a look how:
A team of developers (let’s call them A, B and C) check in the code in the shared repository throughout the day.
Jenkins server monitors the code and prepares a build when the code commits. There are dashboard plugin to monitor the process.
If the build result is successful then execute the next steps. The build fails a notification is sent to the team of developers. There are also Plugins for notification.
On successful build integration, Jenkins runs the unit and acceptance tests. If everything goes well the server labels the build number. In the case of a test, failure mail is sent to the team. There are number of test plugin for such cases.
Lastly, build success mail is also sent to the team.

So, we can easily say that, there is atleast one plugin for each process.

Best Jenkins Plugins to look out for in 2020

* Kubernetes Plugin

This plugin facilitates to run the dynamic agents on the Kubernetes cluster. The plugin helps create the pods. The main feature is that it creates the pods for docker images and ends after each build. The automation of scaling process is the USP of this plug-in. To setup search the following:
Manage Jenkins > Configure System > Cloud > Select ‘Kubernetes’.
The server certificate key, user name, and password are available in kubectl configuration (~/.kube/config).

* AWS CodeDeploy Plugin

The next step is after project build is to deploy it. This plugin helps you to deploy the applications with multiple AWS references. The process is quite simple, you just need to deploy zip files into the AWS instances.
To setup search the following:
Manage Jenkins > Manage Plugins > Choose “Deploy to container Plugin” > install the plugin > Restart the Jenkins server.
For configuration -> Choose the option “Deploy war/ear to a container.”
In the Deploy war/ear to a container section > Remote Server details > Save.

* Blue Ocean Plugin

One of the main features of Jenkins is that it leverages the use of CI through Git. And this plugin does exactly the same by providing a better visibility and reduced complexity. You just need to create a pipeline for a Git server for the first time. Then Blue Ocean asks for the credentials to access the repositories on the Git server.
To install Blue ocean plugin:
Login to Jenkins server > Click ‘Manage Jenkins’ > Manage Plugins > Search for Blue Ocean plugin > Click the checkbox in the Install column > Click either ‘Install without restart’ or ‘Download now and install after restart.’

* Maven Integration Plugin

Maven in conjunction with Jenkins helps produce the JAR and WAR files for the applications. Jenkins here helps in reading the project dependencies from the POM file and builds relevant files. It also understands all kinds of dependencies in POM.
You can install by: Log in to the Jenkins account > Manage Jenkins > Select Manage Plugins > Select the Available tab > Find the Maven Integration plugin and install it.

* JIRA Plugin

JIRA is a most popular tool used for ticketing in agile methodology. However, it is also used in DevOps and very well integrates with Jenkins. The main functionality of JIRA is to track the issues among the team; project management etc. You can add JIRA sites to Jenkins; the plugin automatically creates the link all matching issue names to JIRA.

* ThinBackup Plugin

Many a times we face the issues of data loss, to help overcome this issue this plugin comes to the rescue. It creates the backup with the job history. There is also a feature to make the changes in the backup manager to trigger the job manually or automatically.
Jenkins home page > Manage Jenkins > Manage plugins > Select ThinBackup plugin and install.

* Jenkins Disk-usage Plugin

Imagine you get a Disk Full; it is quite irritating to get it when some crucial task is in progress. To help analyze the disk usage this plugin is used. This plugin periodically calculates the disk consumption every 60 minutes. You can use by going to:
Jenkins Dashboard > Manage Jenkins > Disk Usage.

* Amazon EC2 Plugin

You can use the ‘Amazon ECS Container Service’ plugin to manage Jenkins cloud slaves and deploy mechanism for Docker-based applications on a cluster.
To install this plugin:
Manage plugins screen > “Available” tab > Select the checkbox for ‘Amazon EC2’ > Click “Download now and install after restart” button > Restart Jenkins after the installation is complete.

* GitHub/GitLab Pull Request Builder

This is another popular Git plugin for Jenkins which allows the developers to easily automate code review. Upon initiating a pull request, the plugin retrieves the source and builds results so that developers can quickly see if their code is right.

* Slack notifications Plugin

Provides Jenkins notification integration with Slack or Slack compatible applications like RocketChat or Mattermost. You can send custom messages to a designated Slack channel on a number of different events.

* SCM API

This is essentially used for Supply chain management systems. It provides the API which interacts with SCM applications. It provides alerts to consumers.

* Publish over SSH Plugin

This plugin provides features to send files and run commands over SSH.You can configure your remote hosts on you Manage Jenkins page and then use them on your jobs.

* Monitoring Plugin

This plugin helps to monitor the cpu utilization, memory consumption, HTTp response time, log accounts and much more. With this plugin, you can check and trace the status on the ongoing jobs and view statistics.

* Dashboard View Plugin

As the name suggests the ‘Dashboard view plugin’ gives the team a consolidated view of status of all the tasks. This plugin is basically used for monitoring purposes. It also has time tracking features for better management of Jenkins.

* S3 publisher plugin

when using Jenkins as your build server, you can easily and automatically upload your builds from Jenkins to AWS S3 using the S3 Publisher plugin.This plugins adds Jenkins pipeline steps to interact with the AWS API. Upload a file/folder from the workspace (or a String) to an S3 bucket. It can also create or update the given CloudFormation stack using the given template from the workspace.

* View Job Filters plugin

the ‘View Job Filters plugin’ is a smart way to create different views for your Jenkins jobs. Do you want to group your jobs based on the build status? Or maybe based on their trends or triggers? You will find all of these filtering options and many others in the ‘View Job Filters plugin’, which definitely makes your life easier.

Conclusion

So these are some of the most popular and must have Jenkins plugins , that each Devops team should try integrating in their Jenkins pipeline based on need and use. They will definitely make the life much easier and make your Jenkins workflow much more smooth and easy to use.

Securing your CI/CD pipelines with DevSecOps in 2023

Tue, 09 Mar 2021 17:03:38 +0000

Injecting Security in your CI/CD pipelines

DevOps is well known for the path-breaking changes it has brought in the software industry. The most prominent one is to bring the Dev and Ops team together, to work in sync at all times throughout the application development lifecycle. And the second is to automate pretty much the entire CI/CD pipeline. These two have been the most remarkable transformation brought to us by the DevOps process.

DevOps has been constantly finding ways to make the CI/CD pipeline more efficient and better. Today we cipf-es.org are going to discuss DevSecOps; the process aims to put a security blanket around the entire lifecycle.

In the older processes, the security check-in the older processes for the application used to happen at the later stages usually before the deployment. This practice would result in fixing last-minute code and testing issues which in turn delays the product release.

So, to accelerate the whole process DevOps uses the ‘Shift Left’ approach. The method focuses on bringing the security practice right from the early stages of the DevOps lifecycle. The key is to incorporate test and security at the beginning ensures speedy process.

Securing the application is not which means to be done at a certain point it needs to be done at every step throughout the process. Securing the application is a continuous process that’s why it’s called Continuous Assurance.

Now the question arises what do we need to check for the security?

Automated CI/CD processes are a critical component of DevOps infrastructure. CI/CD orchestration tools like Jenkins, CicleCI, Bamboo, TeamCity,Travis,Buddy etc are increasingly deployed in DevOps processes to improve processes, facilitate faster deployment of software and product delivery, and provide continuous cost reduction.

But we also need to keep in mind that these CI/CD tools are the biggest consumers of secret and confidential data and have access to a lot of sensitive resources such as other apps and services and information like codebases, credentials and databases.

Ensuring that our CI/CD pipelines are protected and secured and cannot be compromised, is a must.Hence we need to think about the ways to protect the pipeline itself.

Security Checks for CI/CD Pipelines

There are several security checks that needs to be performed:

Source Code Vulnerabilities– This check is related to security of the software. If the source code is not protected might be subjected to potential malicious attacks.

OSS Library Vulnerabilities– Well not just source-code, there are high chances that the open source library used in the application can have vulnerabilities.

OSS Version– Open-source libraries come in handy, but there are chances that after a few years that version may be deprecated. If deprecated then there might not be any maintenance or any replacement for the library.

Identifying Compromising Credentials- there is always a possibility of human error when dealing with secrets and credentials within your CI/CD pipeline. However we now have many tools that can scan for secrets and credentials which can be accidentally committed to a source code repository.

There are several other vulnerabilities that the application might be exposed to due to libraries, code infrastructure, or any exposures. So here are some ways as how do we check for Security?

Static Application system Testing (SAST)- The testing is primarily done before code compilation. The testing method analyses the code security vulnerabilities. It is also known as white-box testing. This test happens very early in the SDLC as it helps to fix the code issues.

Active and Passive penetration test (Dynamic Analysis) – The test is described as a dynamic analysis because it checks the system response to variables/parameters that are not constant. In easy language, it checks the application behaviour with real-time values.

Infrastructure Analysis- This involves scanning the actual environment like configuration, server status to understand and analyse the actual drift and what could be the fix for the drift.

These are some of the checks that are performed by the Build/Devops team to ensure a secure CI/CD channel.

You can also refer to our posts on CI/CD, Why Jenkins is so popular and Alternatives to Jenkins.

Understanding CI/CD in a DevOps Toolchain

What makes Jenkins everyone’s favourite in 2020

Jenkins is getting Old, so what are the alternatives in 2021 ?

Security Tools for CI/CD Pipelines

There are many Devops tools available in the market to perform these tests. Let’s have a look at a few tools:

Checkmarx– Facilitates the SAST testing to analyze the code vulnerabilities in the early stages. It can be easily integrated with any CI/CD tool or environment.

IMMUNIO- The tool provides cloud based solution to protect the web application from malicious attacks. The tools is unique because it does not continuously scan the application instead it focuses on possible vulnerabilities.

Aqua Security- The tool gives the security for containers throughout the CI/CD pipeline. The main feature is that it works with all platforms and clouds very well.Aqua security helps save the day, providing container security throughout the DevSecOps pipeline.

OWASP Zed Attack Proxy (ZAP) – One of the most popular tools to protect the web applications from potential threats. It produces ZAP Docker weekly which has all the common vulnerabilities listed.

Twistlock – A multifaceted tool which offers security to containers, hosts, and serverless components.

CyberArk: CyberArk provides a way to keep secrets out of your Jenkins master, off disk, and also out of source control. CyberArk provides a Jenkins plugin which can be uses to provide credentials to your Jenkins jobs at runtime. The plugin securely provides credentials that are stored in Conjur to Jenkins jobs.

WhiteSource: Another type of security risk for your CI/CD pipelines is the open-source vulnerabilities.WhiteSource is a tool that integrates into the DevOps pipeline, and runs continuously in the background, tracking the security, licensing, and quality of open source components and matching them against WhiteSource’s comprehensive database of open source repositories to provide real-time alerts

Chef InSpec: Inspec from Chef is also recommended for scanning your applications and infrastructure. Chef InSpec is an open-source (OSS) automated testing tool for integration, compliance, security, and other policy requirements.

Fortify Webinspect (MicroFocus): Fortify WebInspect is another dynamic application security testing (DAST) security tools that finds and prioritizes exploitable vulnerabilities in your web applications.

The list goes on as there are many more Devops tools available as per the need of the application.

Conclusion

So we now realise that baking security within your Devops CI/CD process is the need of the hour. With more and more organisations adopting and integrating CI/CD tools for their build, release and deployment process, keeping your CI/CD pipelines secure is more important than ever before.

In today’s world, just like quality, security is also a shared responsibility.

In this above post we have tried talking about importance of DevSecOps in your CI/CD pipeline and covered ways and tools that can help you implement standard security measures for pipeline security.

Jenkins is getting Old, so what are the alternatives in 2021 ?

Namrata Joshi — Thu, 22 Oct 2020 08:43:33 +0000

Why You Should Look For Jenkins Alternative? Best Alternatives for Jenkins in 2020-21

Jenkins has been a de-facto standard tool for CI/CD in the Devops pipeline for many years now.However over the last couple of years , it looks like Jenkins is loosing is luster and sheen, especially with the world showing a fast adaptability for technologies like docker and kubernetes.

So is Jenkins going to be a dead and lost tool soon?

Well, its too early to comment or assume such theories, but definitely as the DevOps people we need to keep an eye on the Continuous Change and Continuous Evolvement of new and better tools in the ecosystem.

Jenkins as a CI tool and common issues

Jenkins is one of the essential CI/CD tool for DevOps professionals. It is one of the most trusted and well-known open-source tools. Jenkins is used for building and testing software projects continuously which makes it easy for developers to integrate changes in a project. Jenkins is a continuous integration software tool.

However, since the last few years, Jenkins has been losing its shine and reputation. Jenkins enjoys a lots of love and support from the community and also many plugins to support the Jenkins ecosystem.

Off-late a lot of Jenkins plugins have become redundant, and are no longer maintained.Also not all plugins are compatible with the new Declarative style of pipelines. Jenkins again is an old tool and was not designed for the new container age technologies. Jenkins also does not get well with a microservices kind of architecture.

In general Jenkins as a tool still holds value for following use-cases:

You are using an on-premise solution.
Most of your codebase is hosted in-house.
You have a big team to take care of and manage Jenkins pipelines dedicatedly.
You are tight on budget, and looking for free open-source CI solutions.
You still follow the legacy monolithic approach and are away from microservices , containers etc

Why we should look for Jenkins alternatives?

Jenkins is the most popular and widely used CI/CD tool , and an important reason for that is, Jenkins is free.

Now lets us try looking at some of the challenges when using Jenkins:

Jenkins has an old and outdated interface and not as user friendly as compared to other tools.
As a regular Jenkins user, it is very common to get challenged and frustrated by some missing functionality,a lot of maintenance issues, broken pipelines, Jenkins dependencies and not to forget scaling issues.
Also with the world moving towards AI/ML based solutions, Jenkins still does not provide analytics for the end-to-end metrics.
Jenkins doesn’t allow a developer to see the commits done by another team member, readily.
When using Jenkins,a common problem is tracking and accountability of the changes made by the various members of the development team.All the traceability is only at the code level provided by a source control tool like GIT.

Hence we should be on a lookout for other possible Continuous Integration solutions because of these drawbacks of Jenkins.

So we are trying to share some Jenkins alternatives that are definitely worth exploring in 2021.

Here is a list of Jenkins like tools for the developers to give a try in 2021 :

What makes Jenkins everyone’s favorite in 2020

Tue, 20 Oct 2020 06:58:24 +0000

Why Jenkins is so popular among DevOps

Software development requires meticulous planning and strategy right from the inception of the idea of the product to delivering it to the end-users. A software application goes through many stages before it is ready to use by the customers. The different phases that a software application goes through before turning into reality is called a Lifecycle. Similarly, DevOps methodology also follows a lifecycle, the stages are as follows:

Continuous Development
Continuous Integration
Continuous Testing
Continuous Deployment
Continuous Monitoring

Each of the stages is very crucial and holds its own importance in software development. However, we are primarily going to focus on Continuous Integration and related tools.

Let’s take a scenario to understand why Continuous Integration is required

A team of 3 developers (let’s call them A, B, and C) are working on an android application for sales personnel for a telecom company. Each of them has been assigned a different module to work upon. All of them are working independently and keep pushing the code on the repository every day. After a few months, the code development stage is over and now it’s time to integrate all the modules. As the integration phase starts, the team starts to face the real challenge. The integrated application does not work as per the expectations also there are newly found bugs in the testing than ever. The deadline is now approaching and the end product is still not ready to use.

The above scenario is no less than a nightmare but what could have the team done differently? The answer is in the next section.

Continuous Integration (CI)

The process implies a development practice where the developer’s team checks in the code regularly in the shared repository. Each developer can push the code several times throughout the day. The integrated version control system builds and tests the latest code in case any conflict happens between the old and latest code. So, Continuous Integration detects and resolves the errors in the early stage.

Sounds so relieving, isn’t it? To know how CI has implemented it, keep scrolling down.

Continuous Integration, How to do it?

So, we need a tool that can facilitate us in implementing the CI pipeline effectively. The answer to all the queries is Jenkins, a popular and very powerful application.

Jenkins is a self-contained, open-source automation tool which can be used to automate all sorts of tasks related to building, testing, and delivering or deploying software.

The three tasks of the software development process are done with a single tool!! Amazing, right? Now let’s look at how it works?

How does Jenkins work?

In the previous section, we looked at the practices before the advent of Jenkins. The process of integration without any automation tool was really cumbersome and the most tedious part. But with Jenkins, the same process is no more a nightmare. So, here is a pictorial representation to understand the Jenkins working.

A team of developers (let’s call them A, B and C) check in the code in the shared repository throughout the day.

Jenkins server monitors the code and prepares a build when the code commits.

If the build result is successful then execute the next steps. If the build fails a notification is sent to the team of developers.

On successful build integration, Jenkins runs the unit and acceptance tests. If everything goes well the server labels the build number. In the case of a test, failure mail is sent to the team.

Lastly, build success email is also sent to the team.

What makes Jenkins so popular among DevOps?

Now that we know and understand how Jenkins works. But what makes it so special? Let’s find out.

Jenkins is an open-source continuous integration tool that works on the Java framework. It is primarily used to facilitate the CI process. Jenkins’s popularity lies in its features and advantages.

So let us have a look at some key benefits of using this tool:

Easy installation and configuration Jenkins is platform-independent. It can run on any Windows, UNIX, and Mac operating systems. All the developer requires is to install Java on the system.

Open-Source Jenkins is an open-source tool and has a huge contributing community. The tool is free which is a big plus.

Massive Plug-in options Jenkins provides a lot of third-party plug-ins with the help of which various other tools can interact with Jenkins pipeline. Jenkins offers a wide range of plug-ins ranging from testing, monitoring to notification purposes.

Ease of distribution The Jenkins tools pretty much automate the entire integration process. The early detection of errors in code building to finding bugs during testing makes the software development process quicker and efficient.

Strong feedback system Jenkins has a very strong feedback mechanism. The developer’s team gets notified about any build job failure or a successful test result instantly via mail.

Master-slave architecture The master-slave architecture feature makes Jenkins a dark horse among the available CI tools in the market. This idea behind using the architecture is to reduce the traffic on a single CI server.
