How to connect Codefresh to your ArgoCD endpoint
Before you can use Codefresh and ArgoCD together, you need to connect your ArgoCD installation in your Codefresh account. This way Codefresh will send and receive information from your ArgoCD instance.
Creating your ArgoCD integration in Codefresh
To configure the integration go to your Account Configuration, by clicking on Account Settings on the left sidebar. On the first section called Integrations click the Configure button next to GitOps.
Click the Add GitOps Provider button from the drop-down menu and follow the on-screen instructions.
To connect to an existing ArgoCD installation you need to use the Codefresh CLI. The Codefresh cli will install an agent in your cluster (in the same namespace that ArgoCD runs) that will handle all communication between ArgoCd and Codefresh.
You can install the CLI by following its documentation. Once it is installed you need to authenticate it with your Codefresh account by creating an API token. Make sure that you choose all scopes if this is the first time you authenticate your CLI with Codefresh.
Once the CLI is authenticated, run the installation command:
codefresh install gitops argocd-agent
Please note that this command must be run from a workstation that has a kubeconfig context pointing to the ArgoCD cluster. You can also run it from your cloud console if you install codefresh CLI there.
Answer the questions asked by the wizard. These include:
- The name of the integration (user-defined)
- Your ArgoCD URL, username and password (you can also use an auth token instead of password)
- The context and namespace in the cluster where ArgoCD is installed
- If you want to automatically import your ArgoCD applications to Codefresh
[email protected]$ codefresh install gitops argocd-agent ? Codefresh integration name argocd ? Argo host, example: https://example.com https://126.96.36.199/ ? Do you want use argocd auth token instead username/password auth? No ? Argo username admin ? Argo password ****************************** Integration updated ? Select Kubernetes context gke_codefresh-support_us-central1-c_kostis-argo ? Select Kubernetes namespace argocd ? Select argocd sync behavior please Do not import anything from Argo to Codefresh argocd-agent "ClusterRole" already exists argocd-agent "ClusterRoleBinding" already exists argocd-agent "Deployment" already exists argocd-agent "ServiceAccount" already exists Argo agent installation finished successfully to namespace "argocd" [email protected]$
Once the installation is complete, you should see the agent health status:
This concludes the basic integration. You can repeat the procedure for different ArgoCD installations by choosing a different name for the integration.
Creating ArgoCD applications
In addition to the existing Kubernetes/Helm environments, you can now create ArgoCD applications via the Codefresh UI.
Visit your GitOps dashboard by clicking on GitOps from the left sidebar. The click the Add Application button at the top right.
If you already have an application setup in ArgoCD, you can enter its project and name and Codefresh will automatically retrieve all information from the ArgoCD instance.
You can also create a brand-new application with the provision option. In this dialog you can enter the exact same details that ArgoCD asks when creating a new application.
The options are:
- Name - User defined name of the Codefresh environment dashboard
- Project - A way to group/secure applications. Choose default if you have only one project in ArgoCD.
- Application - name of application
- Manual/automatic sync - If automatic when a git commit happens, a deployment will automatically take place.
- Use schema - Kubernetes manifests will be checked for correctness before deployed to the cluster
- source repository - Git repository that holds your Kubernetes manifests
- revision - Revision to be checked out when a deployment happens
- path - folder inside the Git repository that should be searched for manifests (if your Git repo has multiple applications)
- cluster - Kubernetes cluster when deployment will take place
- namespace - Kubernetes namespace where the application will be deployed to
- directory recurse - wether to check all folders in the Git repository for manifests in a recursive way.
For a sample application you can use the https://github.com/codefresh-contrib/gitops-kubernetes-configuration repository (or even fork it on your own GitHub account first).
Codefresh will communicate with ArgoCD via its API and pass all the relevant details.
The end result is a new entry for your ArgoCD application will now appear in the dashboard along with the sync status.
