Argo CD is a declarative, GitOps continuous delivery tool designed specifically for Kubernetes. Argo CD treats your Git repositories as the single source of truth and ensures that the desired application state defined in Git is consistently synchronized with the actual state in Kubernetes clusters. Upon detecting any discrepancies between these states, Argo CD can automatically or manually synchronize the configurations to align the cluster's current state with the desired state. This approach streamlines application deployments and enhances visibility and control over application lifecycles.
Why Look for an ArgoCD Alternative?
Argo CD is an exceptional tool for Git synchronization, but it lacks certain capabilities that are required for robust Continuous Deployment. The challenges of Argo CD and the capabilities that Argo CD natively lacks are:
- Fragmented Progressive Delivery: While ArgoCD provides the capability to sync Git repositories to Kubernetes clusters, it requires support from the ecosystem tools to manage advanced deployment strategies. You can’t rely on ArgoCD, you need to manage some external tools like Flagger to handle your advanced deployments.
- Limited Security and Compliance: When it comes to managing security and compliance, ArgoCD does not have any capability to scan images for vulnerabilities before deployments. You need to handle the security scanning and compliance activities outside of ArgoCD, like at the CI stage.
- No Native SLO-Based Rollbacks: ArgoCD lacks native support for these SLO-based Rollbacks and Auto-remediations. To have these, you need to maintain manually written scripts or need to manage external tools from the ecosystem.
- Operational Challenges: Teams need to manage multiple tools simultaneously along with their Kubernetes cluster and ArgoCD instance, which slows down the operational speed of teams and creates unnecessary complications.
Key Evaluation Criteria for GitOps Tools
When evaluating other GitOps tools as alternatives to Argo CD, it's essential to assess them based on several critical criteria to ensure they align with your needs. Some of the criteria to check can be:
- Kubernetes-Native Architecture: The alternative tool should be designed to integrate seamlessly with Kubernetes, leveraging its native features for efficient deployment and management of your cloud native applications.
- Multi-Cluster Deployment Support: Ensure the tool can manage deployments across multiple clusters, facilitating smooth scalability without increasing overhead work.
- Role-Based Access Control (RBAC): The tool should facilitate robust RBAC capabilities to define and enforce user permissions effectively, enhancing security and compliance.
- GitOps Automation and Drift Detection: The tool should automatically synchronize the desired state from Git repositories to the cluster and detect configuration drifts, ensuring consistency and reliability.
- Extensibility and CI/CD Integrations: Consider tools that offer flexibility to integrate with existing CI/CD pipelines and other DevOps tools, allowing for a cohesive workflow.
- User Interface and Usability: A user-friendly interface can significantly enhance productivity by simplifying complex deployment processes and providing clear visibility into application states.
