Argo CD

Description

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes.

Argo CD follows the GitOps pattern of using Git repositories as the source of truth for defining the desired application state. Kubernetes manifests can be specified in several ways:

• kustomize applications
• helm charts
• jsonnet files
• Plain directory of YAML/json manifests
• Any custom config management tool configured as a config management plugin

Argo CD automates the deployment of the desired application states in the specified target environments. Application deployments can track updates to branches, tags, or be pinned to a specific version of manifests at a Git commit.

Uses and Functionnalities

• Automated deployment of applications to specified target environments
• Support for multiple config management/templating tools (Kustomize, Helm, Jsonnet, plain-YAML)
• Ability to manage and deploy to multiple clusters
• SSO Integration (OIDC, OAuth2, LDAP, SAML 2.0, GitHub, GitLab, Microsoft, LinkedIn)
• Multi-tenancy and RBAC policies for authorization
• Rollback/Roll-anywhere to any application configuration committed in Git repository
• Health status analysis of application resources
• Automated configuration drift detection and visualization
• Automated or manual syncing of applications to its desired state
• Web UI which provides real-time view of application activity
• CLI for automation and CI integration
• Webhook integration (GitHub, BitBucket, GitLab)
• Access tokens for automation
• PreSync, Sync, PostSync hooks to support complex application rollouts (e.g.blue/green & canary upgrades)
• Audit trails for application events and API calls
• Prometheus metrics
• Parameter overrides for overriding helm parameters in Git

CICD integration method

Argo CD is used to deploy the whole stack so it is a mandatory dependency, it cannot be deactivated.

ArgoCD is automatically integrated into CICD, which is the deployment tool. There is no way to disable it.
