QUESTION
What is the best way to trigger an argo workflow from an API request?
The API request is handled by a web server, how does the server submits the workflow to the argo server? Using the CLI? using a rest request? What is the best/recommended approach here?
...ANSWER
Answered 2021-Jun-08 at 13:33There's no one "right way." But here are some of the options, so you can pick the one that makes the most sense for your application:
Use the Argo API
with an SDK (Java, Go, Python)
If your API is written in Java, Go, or Python, and if your interactions with Argo are more complex than simply submitting a Workflow (for example, if you're also listing Workflows and would like a nice representation of those objects), an Argo Workflows SDK might be a good choice. In my experience the SDKs have quirks and bugs, so I'd only dive in if you need a more full-featured client.
directly with some HTTP client
If your use case is very simple (like submitting a small Workflow with a WorkflowTemplate reference), I would recommend using a direct HTTP call to the Argo or Kubernetes API. If your language has a robust Kubernetes SDK, that's a solid choice as well.
Use a webhook
The webhook endpoint is technically part of the API, but it's a bit different. The API is basically a specialized version of the Kubernetes API, tailored to the Argo CRDs. The
events
API endpoint provides some additional features specific to kicking off workflows.Use the CLI
You'd have to fork the CLI process from your server code, so this probably isn't the "cleanest" approach.
Use Argo Events
Argo Events is a separate but closely-related project. It can accept a variety of inputs (webhooks, pub/sub messages, etc) and then trigger a Workflow.
Argo Events could make sense if, for example, you want an external record of all the workflows submitted. Pub/sub would give you that record.
Use the Kubernetes API or CLI
Workflows are just Kubernetes resources, so you can just submit them via Kubernetes mechanisms if you like.
As I'm sure you can tell, it really depends on the application. Let me know if any of these needs clarification.
QUESTION
I'm trying to configure a canary rollout for a demo, but I'm having trouble getting the traffic splitting to work with linkerd. The funny part is I was able to get this working with istio and i find istio to be much more complicated then linkerd.
I have a basic go-lang service define like this:

QUESTION
Okay, the title is quite mouthful. But it's actually describing the situation.
I deployed a service on GKE in namespace argo-events. Something was wrong with it so I tore it down:
...ANSWER
Answered 2021-May-28 at 06:01By using command $ kubectl get all
you will only print a few resources like:
- pod
- service
- daemonset
- deployment
- replicaset
- statefulset
- job
- cronjobs
It won't print all resources which can be found when you will use $ kubectl api-resources
.
Example
When create PV
from PersistentVolume documentation it won't be listed in $ kubectl get all
output, but it will be listed if you will specify this resource.
QUESTION
Argo CD shows two items from linkerd (installed by Helm) are being out of sync. The warnings are caused by the optional preserveUnknownFields: false
in the spec
section:
trafficsplits.split.smi-spec.io
serviceprofiles.linkerd.io
But I'm not able to figure out how to ignore the difference using ignoreDifferences
in the Application
manifest. The /spec/preserveUnknownFields
json path isn't working. Is it because the field preserveUnknownFields is not present in the left version?

QUESTION
Workflow:
...ANSWER
Answered 2021-May-13 at 19:02As mentioned in the comments, there are a couple issues with your manifests. They're valid YAML, but that YAML does not deserialize into valid Argo custom resources.
- In the Workflow, you have duplicated the
parameters
key inspec.templates[0].inputs
. - In the WorkflowTemplate, you have placed the
configMapRef
andsecretRef
names at the same level as the keys.configMapRef
andsecretRef
are objects, so thename
key should be nested under each of those.
These are the corrected manifests:
QUESTION
So, I have an Argocd installation where I am using Google Managed Certificates to use SSL.
As per Argocd Ingress Documentation there is no official way defined to do this. To use the Google Managed Certificates I have created the following manifest files.
gcp-managed.yaml
...ANSWER
Answered 2021-May-06 at 09:27So, the trick was to use the argocd command reference --insecure
flag.
Creating a custom argocd service, turning off proxy in Cloudflare and using an ingress which was using the managed certificate.
development-argocd-static-ip
= a static IP which is global in nature
argocd-server, gcp-managed, argocd-service, argocd-ingress
all are in the same namespace
argocd-server.yaml

QUESTION
following are my files for html, .ts and json . As json data was very extensive therefore i have just added a few states and their cities. my 1st dropdown is showing all states. Now I want to match my 1st dropdown's selected value of state with a key "state" in "cities" object in my json file so i can populate 2nd dropdown with cities relevant to that state. and I want to do this in function "getCitiesForSelectedState". please help me find solution for this.
//.ts file
...ANSWER
Answered 2021-Apr-27 at 16:44You can do it with the $event
parameter.
Make sure to compare your values safely.
If your value is not in the right type or has spaces or unwanted chars, this c.state == val
might not work.
You can use the trim
function to compare your value safely:
c.state.trim() == val.trim()
