Argo CD
Argo CD manages Kubernetes application deployments using configurations stored in Git, helping teams automate releases and monitor deployment consistency.
Why it caught my attention
Kubernetes deployments can become difficult to track when teams manage several applications and environments. Argo CD offers a different approach: Git records how applications should be configured, while a central interface shows what is actually running and where the two differ.
What problem does this actually solve?
Argo CD could be worth considering if you recognise any of these challenges.
Repetitive application deployment tasks
Manually applying configuration changes takes time. Argo CD can deploy updates automatically when tracked Git configurations change.
Configuration changes go unnoticed
Running applications can drift from their intended configuration. Argo CD detects differences and makes them visible.
Multiple environments become difficult to manage
Managing deployments across Kubernetes clusters becomes complicated. Argo CD provides a consistent way to control application configurations.
Limited visibility into deployment status
Teams struggle to understand deployment health. Argo CD shows application status, synchronisation problems and resource health.
Is this a good fit for you?
A quick way to see if Argo CD is relevant for your situation.
- You deploy applications to Kubernetes clusters regularly.
- Your team already stores application configurations in Git repositories.
- You want automated deployments without giving CI pipelines direct cluster access.
- You manage applications across several Kubernetes clusters or environments.
- You need clearer visibility into deployment changes and configuration drift.
- Your applications run entirely outside Kubernetes.
- You need a complete build, test and deployment pipeline in one tool.
How does it work?
In practice, the workflow looks something like this:
Deploy Argo CD into a Kubernetes cluster and configure access through its web interface or command-line tools.
Point Argo CD towards a Git repository containing Kubernetes manifests, Helm charts or other supported application definitions.
Create an application specifying which configuration to use and the Kubernetes cluster and namespace where it should run.
Argo CD compares the live application with Git and applies the desired configuration through manual or automatic synchronisation.
Review application health and configuration differences, then investigate problems or enable automatic correction of supported changes.
What else should I know?
A few important things to be aware of before you investigate further.
Kubernetes is a requirement
Argo CD is designed for Kubernetes deployments, not general-purpose application delivery to virtual machines or traditional servers.
Automation requires deliberate configuration
Automatic synchronisation, resource deletion and correction of live configuration changes have separate settings and safeguards.
Production deployment needs planning
Argo CD runs inside Kubernetes. Production environments should consider high availability, access permissions and ongoing maintenance.
Open source does not eliminate operational costs
Argo CD uses the Apache 2.0 licence, but hosting, administration, security and support remain your responsibility.
