argo get hello-world-xxx -n argo                            # get info about a specific workflow
argo logs hello-world-xxx -n argo                           # print the logs from a workflow
argo delete hello-world-xxx -n argo                         # delete workflow

argo template create slack.yaml -n argo # create template resource

--- it's also possible to use kubectl to update resources ( argo is just a CRD ), but argo cli executes that for you

kubectl -n argo apply -f simple.yaml

Core K8 resource types (Kind:xxx)

• Workflow

• WorkflowTemplate

• CronWorkflows

• Sensor - event-driven workflow, sensors are responsible for watching for specific events from various sources and triggering workflows based on those events.

---

Template types

• Container
• Script
• Resource = operation inside cluster - eg.configmap
• Suspend = suspend executionapiVersion: argoproj.io/v1alpha1

Template invocators - invoke/call other templates and provide execution control

• Steps - seznam stepu
• DAG - graph of dependencies

Rozdíl mezi Workflow a CronWorkflow

Workflow: Jednorázový běh, který je spuštěn manuálně pomocí příkazu argo submit. Tento typ workflowu se vykoná jednou v okamžiku jeho nasazení.

CronWorkflow: Opakovaný (plánovaný) běh, který je spuštěn automaticky na základě definovaného časového plánu, podobně jako cron úloha v Linuxu. CronWorkflow je spravován Kubernetes a nasazuje nové instance Workflow dle plánu.
