What is Argo CD? And When Was Argo CD Established?

What Is Argo CD?

Argo CD is declarative Kubernetes GitOps continuous delivery.

In DevOps, ArgoCD is a Continuous Delivery (CD) technology that has become well-liked for delivering applications to Kubernetes. It is based on the GitOps deployment methodology.

When was Argo CD Established?

Argo CD was created at Intuit and made publicly available following Applatix’s 2018 acquisition by Intuit. The founding developers of Applatix, Hong Wang, Jesse Suen, and Alexander Matyushentsev, made the Argo project open-source in 2017.

Why Argo CD?

Declarative and version-controlled application definitions, configurations, and environments are ideal. Automated, auditable, and easily comprehensible application deployment and lifecycle management are essential.

Getting Started

Quick Start

kubectl create namespace argocd kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml

For some features, more user-friendly documentation is offered. Refer to the upgrade guide if you want to upgrade your Argo CD. Those interested in creating third-party connectors can access developer-oriented resources.

How it works

Argo CD defines the intended application state by employing Git repositories as the source of truth, in accordance with the GitOps pattern. There are various approaches to specify Kubernetes manifests:

Applications for Customization

Helm charts

JSONNET files

Simple YAML/JSON manifest directory

Any custom configuration management tool that is set up as a plugin

The deployment of the intended application states in the designated target settings is automated by Argo CD. Deployments of applications can monitor changes to branches, tags, or pinned to a particular manifest version at a Git commit.

Architecture

The implementation of Argo CD is a Kubernetes controller that continually observes active apps and contrasts their present, live state with the target state (as defined in the Git repository). Out Of Sync is the term used to describe a deployed application whose live state differs from the target state. In addition to reporting and visualizing the differences, Argo CD offers the ability to manually or automatically sync the current state back to the intended goal state. The designated target environments can automatically apply and reflect any changes made to the intended target state in the Git repository.

Components

API Server

The Web UI, CLI, and CI/CD systems use the API, which is exposed by the gRPC/REST server. Its duties include the following:

Status reporting and application management

Launching application functions (such as rollback, sync, and user-defined actions)

Cluster credential management and repository (k8s secrets)

RBAC enforcement

Authentication, and auth delegation to outside identity providers

Git webhook event listener/forwarder

Repository Server

An internal service called the repository server keeps a local cache of the Git repository containing the application manifests. When given the following inputs, it is in charge of creating and returning the Kubernetes manifests:

URL of the repository

Revision (tag, branch, commit)

Path of the application

Template-specific configurations: helm values.yaml, parameters

A Kubernetes controller known as the application controller keeps an eye on all active apps and contrasts their actual, live state with the intended target state as defined in the repository. When it identifies an Out Of Sync application state, it may take remedial action. It is in charge of calling any user-specified hooks for lifecycle events (Sync, PostSync, and PreSync).

Features

Applications are automatically deployed to designated target environments.

Multiple configuration management/templating tools (Kustomize, Helm, Jsonnet, and plain-YAML) are supported.

Capacity to oversee and implement across several clusters

Integration of SSO (OIDC, OAuth2, LDAP, SAML 2.0, Microsoft, LinkedIn, GitHub, GitLab)

RBAC and multi-tenancy authorization policies

Rollback/Roll-anywhere to any Git repository-committed application configuration

Analysis of the application resources’ health state

Automated visualization and detection of configuration drift

Applications can be synced manually or automatically to their desired state.

Web user interface that shows program activity in real time

CLI for CI integration and automation

Integration of webhooks (GitHub, BitBucket, GitLab)

Tokens of access for automation

Hooks for PreSync, Sync, and PostSync to facilitate intricate application rollouts (such as canary and blue/green upgrades)

Application event and API call audit trails

Prometheus measurements

To override helm parameters in Git, use parameter overrides.

A Comprehensive Guide to GitOps: Benefits, Challenges, and Core Principles

Although often seen as a new approach, GitOps has been a foundational strategy in the tech industry for infrastructure automation, continuous deployment, and system administration. According to a CNCF survey, over 60% of respondents have used GitOps methods and tools for more than a year. This widespread adoption highlights GitOps' reliability and effectiveness in managing complex systems and automating routine tasks. Let's explore GitOps further, focusing on its benefits and the reasons behind its growing popularity.

What Is GitOps?

GitOps (Git Operations) is an operational framework based on DevOps practices like CI/CD and version control, aimed at automating infrastructure and software deployment. It enables developers to store the desired state of their infrastructure and use it to automate operational tasks. GitOps is applied from the beginning of the development workflow through to deployment.

This approach is developer-centric, leveraging tools that developers are already familiar with, such as Git. It extends the use of Git beyond application code to include application configuration, infrastructure, and operational procedures.

Principles of GitOps

GitOps is grounded in a set of core principles that guide the management and operation of software systems. These principles include using automation tools to apply changes to the target environment, continuously synchronizing the system with the Git repository, and storing the desired state of the system declaratively in a Git repository. By adopting these practices, organizations can enhance the efficiency, reliability, and traceability of infrastructure and application configuration management. GitOps emphasizes using Git as the single source of truth for system state, aligning with other DevOps methodologies.

Benefits of GitOps

Efficiency and Automation: GitOps automates infrastructure and frequent deployments. With Git as the source of truth, processes are streamlined, manual work is minimized, and productivity is increased. Studies show that GitOps reduces lead times by empowering developers to work independently.

Transparency and Collaboration: GitOps uses Git repositories and pull requests for infrastructure changes, providing visibility, review, and auditing capabilities.

Reliability and Stability: By declaring the desired state of the system in Git, the system can converge to that state, reducing downtime and enabling quick rollbacks, leading to a stable environment for both developers and operations teams.

Version Control and Auditing: Git provides version control, offering a history of changes and the ability to revert if necessary, ensuring accountability and auditability for configuration changes.

Security and Compliance: GitOps helps enforce compliance standards and security best practices. By using pull requests and code reviews, it helps identify and address security vulnerabilities, reducing attack surfaces and enhancing overall system security.

Scalability and Multi-Environment Management: GitOps is ideal for managing multi-cluster, multi-environment, and complex deployments. It offers a scalable approach to handling infrastructure configurations, facilitating the management of heterogeneous environments and scaling applications effectively.

Challenges of GitOps

Implementing GitOps comes with its own set of challenges:

Change Management: Transitioning to GitOps requires a cultural shift and discipline from all team members, who must document everything and embrace new workflows.

Collaboration: While GitOps promotes collaboration, it may be challenging for organizations and individuals accustomed to making quick, manual changes. The process of making changes via merge requests and approvals can seem slow and cumbersome.

GitOps vs. DevOps

While both GitOps and DevOps are popular in software development and operations, they have distinct differences. DevOps focuses on integrating development and operations teams through selected tools, while GitOps emphasizes managing and deploying infrastructure changes using Git as the single source of truth. GitOps relies on continuous synchronization and declarative configurations stored in Git repositories, whereas DevOps prioritizes automation and collaboration throughout the software development lifecycle. Understanding these differences helps organizations choose the approach that best meets their goals and needs.

GitOps Workflow

The GitOps workflow is a systematic approach to managing software systems and infrastructure, using Git repositories as the single source of truth. It involves employing automation tools to continuously synchronize the system with the repository and storing the desired state of the system declaratively in a Git repository. When new code or configuration changes are merged into the repository, the system automatically converges to the desired state and deploys these changes to the target environment. This workflow, aligned with modern DevOps practices, enhances the effectiveness, reliability, and traceability of infrastructure and application configuration management.

Use Cases of GitOps

For Platform Engineers: GitOps can enhance infrastructure management by allowing platform engineers to track, roll back, and maintain consistent configurations across multiple environments. It also supports automated updates and deployments, reducing manual efforts.

GitOps with Kubernetes: It provides an effective deployment management solution for teams delivering containerized applications on Kubernetes or other cloud-native environments. GitOps' declarative nature aligns well with Kubernetes' architecture, enabling automatic resolution of discrepancies between the cluster's actual state and the desired state as defined in Git. It also manages complex Kubernetes deployments involving multiple clusters and environments.

Conclusion

GitOps is a powerful approach for managing infrastructure and software systems. By leveraging Git as the single source of truth, organizations can achieve operational efficiency, transparency, reliability, and scalability. GitOps fosters automation, collaboration, version control, and traceability, enabling teams to streamline deployments, improve communication, ensure stability, and enforce security and compliance. With its focus on continuous synchronization and declarative configurations, GitOps empowers organizations to achieve scalable, reliable, and efficient infrastructure management and software delivery, ultimately boosting operational excellence, reducing downtime, and increasing productivity.
