GitOps with Imixs-Cloud

Imixs-Cloud provides with its directory structure of separate sub-directories for each application the core concept of Infrastructure as Code. Stored in a Git repository this enables declarative, continuous deliverys - called GitOps. All objects are provided in a root git repository:

/-
 |+ management/
    |- monitoring/
    |- registry/
    |- nginx/
 |+ apps/
    |+ MY-APP/
       |  001-deployment.yaml
    .....

Argo CD

Argo CD is a GitOps continuous delivery tool for Kubernetes. Running Argo CD within the Imixs-Cloud provides a convenient way to control application definitions, configurations, and environments in a declarative way. By adding Argo CD you extend the way to control all your applications running with the Imixs-Cloud.

Quick Setup

For a quick setup we use the official install.yaml file form the argo-cd github page.

$ kubectl create namespace argocd
$ kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml

The startup may take some seconds.

For the Ingress configuration the directory /management/argo-cd includes additional resource objects. Edit the file ‘030-ingress.yaml’ and replace ‘{YOUR-DOMAIN-NAME}’ with your Internet domain name.

Next you can apply the Ingress configuration to your running argo-cd instance:

$ kubectl apply -f management/argo-cd/030-ingress.yaml

In the official Getting Started Guide of the Argo CD project you will find additional information.

First Login

For the first login argo-cd generates a random password for the user ‘admin’. The password can be retrieved with the command:

$ kubectl -n argocd get secret argocd-initial-admin-secret -o jsonpath="{.data.password}" | base64 -d; echo

Using the username admin and the password from above, you can login to Argo CD’s Web UI.

Configure a Application

Argo CD allows you to configure the deployment for each of your application manually in various ways. After you have added your Git repository you can add a application to be monitored by Argo CD
