A green build signals that the code is working, it means that the software developed by the teams is in a state that can be released to the customer. Below I will present several items that should be met to consider a build as a green build: X% of code coverage from Unit Test (If test coverage is minor than % defined the build gets red)

What is the difference between continuous delivery and release pipeline?
Continuous delivery (CD) is the process of automating build, test, configuration, and deployment from a build to a production environment. A release pipeline can create multiple testing or staging environments to automate infrastructure creation and deploy new builds.
How do I set up a continuous delivery pipeline?
Use AWS CodePipeline to set up the continuous delivery pipeline with source, build, and deploy stages The diagram below provides a visual representation of the services used in this tutorial and how they are connected. This application uses GitHub, AWS Elastic Beanstalk, AWS CodeBuild, and AWS CodePipeline as pictured below.
What are the different stages of a CD pipeline?
There is no such thing as The Standard Pipeline, but a typical CD pipeline will include the following stages: build automation and continuous integration; test automation; and deployment automation. The pipeline starts by building the binaries to create the deliverables that will be passed to the subsequent stages.
What is a pipeline in software development?
The pipeline starts by building the binaries to create the deliverables that will be passed to the subsequent stages. New features implemented by the developers are integrated into the central code base on a continuous basis, built and unit tested.
What are three components of the continuous delivery pipeline?
Phases in a continuous delivery pipelineComponent phase.Subsystem phase.System phase.Production phase.
What is a build pipeline?
A pipeline is a process that drives software development through a path of building, testing, and deploying code, also known as CI/CD. By automating the process, the objective is to minimize human error and maintain a consistent process for how software is released.
What are different stages in continuous deployment pipeline?
A continuous delivery pipeline consists of five main phases—build/develop, commit, test, stage, and deploy.
What are the four main stages of a deployment pipeline?
There are four main stages of a deployment pipeline:Version Control.Acceptance Tests.Independent Deployment.Production Deployment.
What is the build stage?
The build stage is the first stretch of a CI/CD pipeline, and it automates steps like downloading dependencies, installing tools, and compiling. Besides building code, build automation includes using tools to check that the code is safe and follows best practices.
What is build and release pipeline?
A Build Pipeline is used to generate Artifacts out of Source Code. A Release Pipeline consumes the Artifacts and conducts follow-up actions within a multi-staging system. It is best practice to establish a link between a Build Pipeline and the corresponding Release Pipeline.
What is build phase in DevOps?
The Build phase is where DevOps really kicks in. Once a developer has finished a task, they commit their code to a shared code repository. There are many ways this can be done, but typically the developer submits a pull request — a request to merge their new code with the shared codebase.
What are two parts of the continuous delivery pipeline?
The Four Aspects of the Continuous Delivery Pipeline. The SAFe continuous delivery pipeline contains four aspects: continuous exploration, continuous integration, continuous deployment, and release on demand.
What is difference between continuous deployment and continuous delivery?
Continuous Delivery is the automation of steps to safely get changes into production. Where Continuous Deployment focuses on the actual deployment, Continuous Delivery focuses on the release and release strategy.
How many stages are there in CI?
The CI/CD pipeline combines continuous integration, delivery and deployment into four major phases: source, build, test and deploy.
What are the two types of pipelines in DevOps?
While continuous delivery enables development teams to deploy software, features, and code updates manually, continuous deployment is all about automating the entire release cycle.
What is build test and deploy?
Test… Build… Deploy cycle; a structured progression of work steps from developing code to testing that code, to building a release version of that code, which is then deployed in a production environment.
What is build pipeline DevOps?
A DevOps pipeline is a set of automated processes and tools that allows developers and operations professionals to collaborate on building and deploying code to a production environment.
What is a build pipeline in Jenkins?
Jenkins Pipeline (or simply "Pipeline") is a suite of plugins which supports implementing and integrating continuous delivery pipelines into Jenkins. A continuous delivery pipeline is an automated expression of your process for getting software from version control right through to your users and customers.
What are two types of pipelines?
Within the energy sector, there are two major types of pipelines, liquids pipelines and natural gas pipelines. Liquid pipelines transport crude oil or natural gas in liquid form to refineries where they undergo distillation and other production processes.
What is mean by build in DevOps?
What Is Build Automation in DevOps? Build automation is the process of automating the retrieval of source code, compiling it into binary code, executing automated tests, and publishing it into a shared, centralized repository. Build automation is critical to successful DevOps processes.
What are the outer and inner rings of a continuous delivery pipeline?
The outer two rings represent the continuous delivery pipeline, with its four aspects and 16 activities wrapped into a closed learning loop. The inner rings represent DevOps practice domains that ‘power’ the CDP. Each domain contains specific practices and tools that members of the value stream use to perform CDP activities. SAFe’s CALMR approach to DevOps, shown at the center of the figure, is the shared mindset that guides behavior and decision making throughout the entire system.
Why is the SAFe continuous delivery pipeline mapped?
Once the current flow is understood, it can be mapped into the SAFe Continuous Delivery Pipeline. Mapping helps the organization adopt a common mental model and provides an efficient means to communicate changes and improvements. Figure 5 removes the labels of “Continuous” because at this stage the process is unlikely to resemble an automated pipeline.
What is the figure 3?
Figure 3. A map of one company’s delivery pipeline
Why is continuous delivery important?
Indeed, it may be the most vital capability of every ART and Solution Train. It’s important that stakeholders can visualize and track the ongoing work , even though a significant portion of it is automated. They need the ability to establish Work in Process (WIP) limits to improve throughput and identify and address bottlenecks. That’s the role of the Program Kanban, as shown in Figure 7.
What is pipeline in Agile?
The pipeline is a significant element of the Agile Product Delivery competency. Each Agile Release Train (ART) builds and maintains , or shares , a pipeline with the assets and technologies needed to deliver solution value as independently as possible . The first three elements of the pipeline (CE, CI, and CD) work together to support the delivery of small batches of new functionality, which are then released to fulfill market demand.
What are the four aspects of the pipeline?
As illustrated in Figure 1, the pipeline consists of four aspects: Continuous Exploration (CE) , Continuous Integration (CI) , Continuous Deployment (CD), and Release on Demand, each of which is described in its own article.
What is continuous exploration?
Continuous Exploration (CE) focuses on creating alignment on what needs to be built. In CE, design thinking is used to ensure the enterprise understands the market problem / customer need and the solution required to meet that need. It starts with an idea or a hypothesis of something that will provide value to customers, typically in response to customer feedback or market research. Ideas are then analyzed and further researched, leading to the understanding and convergence of what is needed as either a Minimum Viable Product (MVP) or Minimum Marketable Feature (MMF). These feed the solution space of exploring how existing architectures and solutions can, or should, be modified. Finally, convergence occurs by understanding which Capabilities and Features, if implemented, are likely to meet customer and market needs. Collectively, these are defined and prioritized in the Program Backlog.
What is pipeline in software?
The pipeline breaks down the software delivery process into stages. Each stage is aimed at verifying the quality of new features from a different angle to validate the new functionality and prevent errors from affecting your users. The pipeline should provide feedback to the team and visibility into the flow of changes to everyone involved in delivering the new feature/s.
What are the stages of a CD pipeline?
There is no such thing as The Standard Pipeline, but a typical CD pipeline will include the following stages: build automation and continuous integration; test automation; and deployment automation.
What is continuous delivery?
Continuous Delivery (CD) is a software strategy that enables organizations to deliver new features to users as fast and efficiently as possible. The core idea of CD is to create a repeatable, reliable and incrementally improving process for taking software from concept to customer. The goal of Continuous Delivery is to enable a constant flow of changes into production via an automated software production line. The Continuous Delivery pipeline is what makes it all happen.
What is automated platform provisioning?
Automated platform provisioning ensures that your candidate applications are deployed to, and tests carried out against, correctly configured and reproducible environments. It also facilitates horizontal scalability and allows the business to try out new products in a sandbox environment at any time.
How to avoid poor system quality?
Poor system quality, low-user satisfaction and endless “quality band-aids” can be avoided by adopting the principle of not adding new functionality before getting the quality right. You should always first meet and maintain your quality levels and only then consider gradually adding functionality to the system.
When is deployment required?
A deployment is required every time the application is installed in an environment for testing, but the most critical moment for deployment automation is rollout time . Since the preceding stages have verified the overall quality of the system, this is a low-risk step. The deployment can be staged, with the new version being initially released to a subset of the production environment and monitored before being completely rolled out. The deployment is automated, allowing for the reliable delivery of new functionality to users within minutes, if needed.
Who is Andrew Phillips?
Andrew Phillips heads up product management at XebiaLabs. Andrew is an evangelist and thought leader in the DevOps, Cloud and Continuous Delivery space. He sits on the management team and drives product direction, positioning and planning.
What is a CD deployment ring?
CD may sequence multiple deployment rings for progressive exposure (also known as "controlling the blast radius"). Progressive exposure groups users who get to try new releases to monitor their experience in rings. The first deployment ring is often a canary used to test new versions in production before a broader rollout. CD automates deployment from one ring to the next and may optionally depend on an approval step, in which a decision maker signs off on the changes electronically. CD may create an auditable record of the approval in order to satisfy regulatory procedures or other control objectives.
What is continuous delivery?
Continuous Delivery (CD) is the process to build, test, configure, and deploy from a build to a production environment. Multiple testing or staging environments create a Release Pipeline to automate the creation of infrastructure and deployment of a new build. Successive environments support progressively longer-running activities of integration, load, and user acceptance testing. Continuous Integration starts the CD process and the pipeline stages each successive environment to the next upon successful completion of tests.
What is CD in production?
CD is a lean practice with the goal to keep production fresh by achieving the shortest path from the availability of new code in version control or new components in package management to deployment. By automation, CD minimizes the time to deploy and time to mitigate or time to remediate production incidents (TTM and TTR). In lean terms, this optimizes process time and eliminates idle time. CD is helped considerably by the complementary practices of Infrastructure as Code and monitoring.
How Is Your Pipeline Structured, and What Did You Use to Build It?
We use GitLab CI, which is GitLab’s technology for writing pipelines. It’s pretty convenient because it easily talks with the codebase and with the container repositories natively, and you get the same UI wherever you manage the code, the tickets and the pipelines themselves. The pipeline has eight simple steps.
Are You Experimenting With Any New Methods or Tools?
Horev: The way we move from the staging environment to the production environment is kind of a new idea: deployment trains.
Testing: Any Tips You Can Share?
Conger: For integration testing, we would run components of our code or the microservices as part of the build process. We spin up Docker Compose environments of multiple containers, so we can do testing right in the pipeline’s ephemeral build environment.
Introduction: Create a Continuous Delivery Pipeline
Follow step-by-step instructions to build your first continuous delivery pipeline.
Overview
In this tutorial, you will create a continuous delivery pipeline for a simple web application. You will first use a version control system to store your source code. Then you will learn how to create a continuous delivery pipeline that will automatically deploy your web application whenever your source code is updated.
What You Will Learn
This tutorial will walk you through the steps to create the continuous delivery pipeline discussed above. You will learn to:
Application Architecture
The diagram below provides a visual representation of the services used in this tutorial and how they are connected. This application uses GitHub, AWS Elastic Beanstalk, AWS CodeBuild, and AWS CodePipeline as pictured below.
Modules
This tutorial is divided into five short modules. You must complete each module in order before moving on to the next one.
What is terraform build?
In our terraform file we make a reference to a file that contains the SSH public key that we want added to the EC2 instance when it’s created. This is then used by Ansible to SSH into the box to provision it. Therefore build has a dependency on the task keys.
What is ansible inventory?
Ansible supports a Dynamic Inventory script. This is a small Python script that connects to AWS and pulls out the EC2 instances you have available. The important thing it does is group and assign these instances to Ansible groups based on the AWS tags you defined when creating them via Terraform.
Why use Ansible templates?
We use Ansible templates so that we can generate the XML files that Jenkins uses to create jobs for the git repository of our project, and to configure the Build Pipeline plugin to create our Continuous Delivery pipeline based on the steps mentioned earlier.
How to setup SSH key for Terraform?
Setting up an SSH key for the instances that Terraform will create is an essential first step. Using ssh-keygen we generate a new key and store it on the local filesystem. Our Terraform configuration will use this to setup a keypair on AWS, which will then be used on the new instance it’ll create. This adds the public key to the authorized_keys file on the new EC2 instance, allowing Ansible to connect further on to install and configure Jenkins.
What is ansible download?
ansible: downloads the dynamic inventory script and also some Ansible roles from Ansible Galaxy
What is the makefile?
Gluing all of this together is the Makefile. This allows us to define the dependencies of our tool by defining tasks and their dependencies. Breaking our Makefile down, we have a few tasks:
Does Ansible use SSH?
Ansible is configured to use the same SSH key that we created in the first step, so that it’s able to connect to the instance. But how does Ansible know which instances to connect to?
The Four Aspects of The Continuous Delivery Pipeline
Start by Mapping The Current Workflow
- Successful enterprises already have a delivery pipeline—otherwise, they wouldn’t be able to release any value at all. But too often they are not automated, contain significant delays, and require tedious and error-prone human intervention. This, in turn, causes organizations to delay releases, increasing their size and scope (“We’ll release when it is big enough”). This is opposite …
Align The Current Workflow to The Continuous Delivery Pipeline
- Once the current flow is understood, it can be mapped into the SAFe Continuous Delivery Pipeline. Mapping helps the organization adopt a common mental model and provides an efficient means to communicate changes and improvements. Figure 5 removes the labels of “Continuous” because at this stage the process is unlikely to resemble an automated pipeline.
Identify Opportunities For Improvement
- Teams look for the opportunity to improve the efficiency of each step, consequently reducing the total lead time. This includes addressing process time, as well as the quality (percent complete and accurate) of each step. The higher that number, the less rework is required, and the faster the work moves through the system. As shown in Figure 6, the delay time (time between steps) is of…
Tracking Continuous Delivery
- When viewed as a whole, continuous delivery is an extensive process. Indeed, it may be the most vital capability of every ART and Solution Train. It’s important that stakeholders can visualize and track the ongoing work, even though a significant portion of it is automated. They need the ability to establish Work in Process (WIP) limits to improve throughput and identify and address bottle…
Enabling The Continuous Delivery Pipeline with DevOps
- Building, maintaining, and optimizing a continuous delivery pipeline requires specialized skills and tooling throughout the entire value stream. Because this type of delivery system calls for rapid delivery of complex solutions with very short learning loops and high degrees of cross-functional collaboration, DevOps methods are perfectly suited to enabling it. In other words, continuous del…
