Editor to share with you how to quickly install and use Argo, I hope you will learn something after reading this article, let's discuss it together!

The Argo project is a collection of native Kubernetes tools for running and managing jobs and applications on Kubernetes. Argo provides a simple combination of three computing modes for creating work and applications on Kubernetes-the service pattern, the workflow pattern, and the event-based pattern. All Argo tools are implemented as controllers and custom resources.

Quick installation

Download page: https://github.com/argoproj/argo-workflows/releases

Linux

Download the client through curl, as follows:

# Download the binarycurl-LO https://github.com/argoproj/argo/releases/download/v3.0.0-rc3/argo-linux-amd64.gz# Unzipgunzip argo-linux-amd64.gz# Make binary executablechmod + x argo-linux-amd64# Move binary to pathmv. / argo-linux-amd64 / usr/local/bin/argo# Test installationargo versionArgo Controller Service installs kubectl create namespace argokubectl apply-nargo-f https://raw.githubusercontent.com/argoproj/argo/v3.0.0-rc3/manifests/install.yaml

Open the node deployment pod:

After installation, use kubectl get pod-n argo to find that it is always in the pending state, and you need to turn on the task deployment of the master node.

Kubectl taint nodes-all node-role.kubernetes.io/master- runs the test

The workflow where the example is run:

Argo submit-n argo-- watch https://raw.githubusercontent.com/argoproj/argo-workflows/master/examples/hello-world.yamlargo list-n argoargo get-n argo @ latestargo logs-n argo @ latest

View UI:

Use port-forward to forward ports:

Kubectl-n argo port-forward deployment/argo-server 2746

The user interface can access http://localhost:2746

Use NodePort:

ApiVersion: v1kind: Servicemetadata: name: nginx-servicespec: type: NodePort sessionAffinity: ClientIP selector:app: nginx ports:- port: 80 nodePort: 30080

Kind:Service representative is a service

Type:NodePort K8s will open a port on each Node and the port of each Node will be the same. Programs outside the Kubernetes cluster can access the Service through: NodePort.

Selector: which services should be exposed

Ports exposed by port:service

Port of TargetPort:pod

The forwarding logic is:

: =:

The service can be accessed by using http://: on the appropriate node.
