Argo-cd-examples

• repo used for demonstrating argo cd

• Using Docker Desktop cluster as KIND does not have access to docker hub

Installing Argo

1. create the namespace

kubectl create namespace argocd

2. apply the install file, this will create all the resources necessary for argo in the argocd namespace

kubectl apply -n argocd -f ./argo_templates/install.yaml

3. Optional, can port forward the UI to see it if you want

kubectl port-forward svc/argocd-server -n argocd 8080:443

• user name is admin, would have to get the password via following command

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

4. Create your app in argo by applying an app yaml

make sure your repo is public or will have to configure your credentials

kubectl apply -n argocd -f ./argo_templates/app.yaml

or via cli

argocd app create --name example \
--repo https://gitlab.com/cfech44/argo-cd-examples.git \
--dest-server https://kubernetes.default.svc \
--dest-namespace default --path example_project/manifest

• Should create the app and the resources and sync with the git repo, can see this on the argocd gui

Updating App and keeping in sync

• once configured argocd should monitor the git repo for updates and sync when necessary

• push update and argo should pick it up and sync it to your cluster

Authentication with Private Repo

https://argo-cd.readthedocs.io/en/release-1.8/user-guide/private-repositories/

could use gui or cli

argocd repo add [repolink] --username <username> --password <password>
