Getting Started with ArgoCD

Output

Hey all, I'm writing this Blog because I faced 3 to 4 errors while getting argoCD up & running which took me lots of time. So, to save yours I'm writing this Blog.

Here, I mentioned the challenges I faced when I was getting started with ArgoCD which you might face too. So, go through this Blog first then get started.

Note: Please refer to the Getting Started documentation of ArgoCD simultaneously.

Let's get started.

Getting Started

Requirements

Install Argo CD

kubectl create namespace argocd

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

Here, you might face the error like: Unable to connect to the server: read tcp [2405:204:8088:9680:8862:5d4a:a1a8:dcb5]:54021->[2606:50c0:8000::154]:443: wsarecv: An existing connection was forcibly closed by the remote host.

So, to avoid this, follow these steps:

i.) Go to the YAML file link itself: Link https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml

ii.) Copy the file.

iii.) Create a new folder named argocd on your Desktop or any place you wish.

iv.) Then paste the content in the file name install.yaml

v.) Finally, run the command kubectl apply -n argocd -f install.yaml in your WSL terminal or Hyper terminal. (After starting, Docker Desktop and running minikube start command)

Note: Follow these same steps if you want core-install.yaml too. In the fourth step name the file core-install.yaml and run the command

kubectl apply -n argocd -f core-install.yaml

The output you will be like:

Install in CLI

If you are using Windows OS. Install ArgoCD CLI via WindowsPowershell:

Link: argo-cd.readthedocs.io/en/stable/cli_instal..

Access the ArgoCD API Server.

ArgoCD must be running on port https://localhost:8080

Here, you might face error like,

$ argocd admin initial-password

time="2023-03-05T12:47:25+05:30" level=fatal msg="secrets "argocd-initial-admin-secret" not found"

To avoid this, use the command $ argocd admin initial-password -n argocd

Now, you may see your password.

Now, to update your password you have to log in through your terminal.

argocd login <ARGOCD_SERVER>

In my case <ARGOCD_SERVER> = localhost:8080

Now, go ahead & update your password.

Now, go and play around with ArgoCD. And do some great projects.
