Getting Started with ArgoCD
Hello Everyone, welcome to my blogging channel. Here, I simplify concepts for beginners. If you want to just follow the tutorial and clone the project for your resume, I simplify that process for you by making you understand the concepts. But, if you want to choose the other way around like you are learning skills to optimize the cost and build something. That's what an engineer would do. Please follow.
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.
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: https://argo-cd.readthedocs.io/en/stable/cli_installation/#windows
Access the ArgoCD API Server.
ArgoCD must be running on port https://localhost:8080
Login Using CLI
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.
