Why Crossplane with ArgoCD is the Best GitOps
When it comes to GitOps workflows, multiple combinations exist:
Flux + Terraform: Great for infrastructure but needs extra handling for state and pipelines.
ArgoCD + Helm: Reliable for app delivery but lacks built-in infrastructure provisioning.
Jenkins + Kustomize: While powerful for pipelines, lacks the declarative and continuous reconciliation capabilities central to GitOps.
Well, this is just a quick snapshot of the essence.
The GitOps Best Practices whitepaper from Akuity (the creators of Argo CD) is a fantastic guide that every cloud-native engineer should read to better understand the nuances of handling modern GitOps systems.
Discussing how to configure Crossplane with Argo CD might seem interesting but adds little value, reducing this write-up to a basic 'how-to' guide.
Instead, let’s focus on...
What Crossplane + ArgoCD Delivers
1. Kubernetes Native Infrastructure Provisioning
With Crossplane, you define infrastructure as Kubernetes Custom Resources (CRs).
This means you no longer need external tools like Terraform to manage infrastructure, simplifying your tech stack.
apiVersion: s3.aws.crossplane.io/v1beta1
kind: Bucket
metadata:
name: techops-bucket
spec:
forProvider:
acl: private
versioningConfiguration:
status: Enabled
providerConfigRef:
name: aws-providerBy syncing these CRs via ArgoCD, Git becomes your single source of truth for both apps and infrastructure.
2. Reusability with Compositions
Crossplane allows you to define reusable infrastructure blueprints using Compositions.
You can standardize your infra setups (like databases, VPCs, or clusters) and dynamically apply them across environments using ArgoCD’s ApplicationSets.
Example: A reusable RDS database composition:
apiVersion: apiextensions.crossplane.io/v1
kind: Composition
metadata:
name: rds-composition
spec:
resources:
- base:
apiVersion: database.aws.crossplane.io/v1beta1
kind: RDSInstance
spec:
forProvider:
dbInstanceClass: db.t3.micro
engine: postgres3. Built in Multi-Cloud Support
Crossplane supports AWS, GCP, and Azure with no additional tooling. Switching cloud providers or creating multi-cloud environments is just a matter of changing configurations in your manifests.
Quick Win for Getting Started
📌 Use Crossplane Compositions to define reusable patterns for databases, VPCs, and more. Combine these with ArgoCD’s ApplicationSets to scale deployments.
