Hey, I'm new to Wiremock. I'm using the Docker image in K8s and can't figure out how to set up the stubs backup. I created a dedicated volume in the root, but missing the last step. Any advice will be much appreciated šŸ™‚

Hi! What do you mean under backup in these regards? Do you want to extract mappings from the server or what?

@Oleg Nenashev I want to save the mappings to the storage when the pod is terminating. And save all new mappings to /mappings as they are created
@Oleg Nenashev tried to set it up like this, doesn't work. /data is my persistent storage volume
Copy code
lifecycle:
          preStop:
            exec:
              command:
              - /bin/sh
              - -c
              - curl -X POST <http://wiremock:8080/__admin/mappings/save>
              - rm -rf /data/
              - cp -R /home/wiremock/ /data/
          postStart:
            exec:
              command:
              - /bin/sh
              - -c
              - cp -R /data/ /home/wiremock/
              - curl -X POST <http://wiremock:8080/__admin/mappings/reset>

What does block you from just keeping the source of truth on the volume and back it using K8s tools up instead of relying ion 
/data
?

Not sure I understand. Which volume are you referring to?
I'm not building the image, pulling it from the repository

Oleg Nenashev

Copy code
apiVersion: v1
kind: Pod
metadata:
  name: wiremock
spec:
  containers:
  - name: wiremock
    image: wiremock/wiremock:2.35.0
    volumeMounts:
    - name: wiremock-storage
      mountPath: /home/wiremock
  volumes:
  - name: wiremock-storage
    emptyDir: {}
v

Vlad Povolotzky

08/30/2023, 10:30 AM
And Wiremock will use wiremock-storage as it's only storage?
o

Oleg Nenashev

08/30/2023, 10:34 AM
For Mappings and Files and everything under 
/home/wiremock
- yes.
v

Vlad Povolotzky

08/30/2023, 10:36 AM
Will give it a try, thanks! I still need to use the
Copy code
<http://wiremock:8080/__admin/mappings/save>
to save the stubs, right?
o

Oleg Nenashev

08/30/2023, 10:37 AM
Yes, it does not sync to the disc without 
save
v

Vlad Povolotzky

08/30/2023, 10:37 AM
Getting this when trying to save: <title>Error 500 java.lang.IllegalArgumentException: Invalid UUID string: save</title>
o

Oleg Nenashev

08/30/2023, 10:37 AM
Personally I recommend switching to the configuration-as-code approach and building your Docker image on the top of the official one, but that's up to you
It is a wrong endpoint. Lemme check

Totally new to all of this, will try to follow this advice in the future :)

@Vlad Povolotzky Do you use POST for 
__admin/mappings/save
? https://wiremock.org/docs/stubbing/#saving-stubs
With GET, it will try to get stub with UUID 
save
v

Vlad Povolotzky

08/30/2023, 10:42 AM
It's POST, sure
o

Oleg Nenashev

08/30/2023, 10:43 AM
If you get 
IllegalArgumentException
with POST, it is a bug. Could you please file one?

@Oleg Nenashev mounted the volume to home/mapping and now calling /save saves the stubs there as it should. How do I load the mappings from the /mappings folder? Currently after container restart a call to /mappings returns empty list.
o

Oleg Nenashev

08/31/2023, 12:46 PM
Do you have a startup log? If the volume is mapped and WireMock has the same home directory and no conflicting parameters, it should load them

08/31/2023, 12:50 PM
That's all there is

Oleg Nenashev

08/31/2023, 1:14 PM
And with verbose options?

Vlad Povolotzky

08/31/2023, 1:42 PM
Do I need to edit the yamls for verbose option?

Oleg Nenashev

08/31/2023, 1:42 PM
Yes, it is a CLI argument
