This repository contains the configuration I used to deploy applications to my Kubernetes clusters with ArgoCD.

Firstly, ArgoCD needs to be installed with the below commands.

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

For external access, I use ingress-nginx as the k8s ingress controller.

Install the ingress-nginx helm chart as a argocd application.

kubectl apply -f apps/ingress-nginx.yaml

For TLS termination, you will need a secret configured with the TLS certificate you wish to use.

kubectl create secret tls ${SECRET_NAME} --key ${KEY_PATH} --cert ${CERT_PATH}

ArgoCD will need to be configure to use HTTP only. This is done with a configmap. Then the ingress can be applied. You may wish to edit the ingress.yaml file to use your desired URL.

kubectl apply -f argocd-cmd-params-cm.yaml
kubectl apply -f ingress.yaml

You will then be able to access the ArgoCD web UI from the configured URL.

The initial admin password can be read from the secret argocd-initial-admin-secret.

k get secret argocd-initial-admin-secret --template={{.data.password}} | base64 --decode

This repository makes use of ArgoCD ApplicationSets (appsets) to deploy the applications. These can be located in the appsets directory.

The main appset is the all appset. This is a Kustomize deployment that has dev and prod overlays. Within each appset there is a apps directory, containing a directory of application configuration files for each application to deploy within that appset.

To deploy the all appset, use the following command, substituting the environment used.

kubectl apply -k appsets/all/overlays/<ENV>/
