带有来自私有存储库的 Docker 图像的 Spring Cloud 数据流 - 未使用 imagePullSecrets。 不能拉图像

Question

So I am unable to Launch a custom task application stored in a private docker repo . All my docker images in Kubernetes come are pulled from this private repo. So the imagePullSecrets works fine but it seems it is not being used by Spring Cloud Dataflow when deploying the task to Kubernetes. If I inspect the pod there is no imagepullSecret set.

The error I get is:

xxxxx- no basic auth credentials

The server has been deployed with the ENV variable which the guide states will fix this

    - name: SPRING_CLOUD_DEPLOYER_KUBERNETES_IMAGE_PULL_SECRET
      value: regcred

I have even tried to add custom properties on a per-application bases

I have read through the guide HERE

I am running the following versions:

Kubernetes 1.15 &

I have been stuck on this issue for weeks and simply can't find a solution. I'm hoping somebody has seen this issue and managed to solve it before?

Is there something else I'm missing?

Answer 1

So I found if I do the following it pulls the image (it seems i put this in the wrong place as the documentation doesn't clearly specify where and how)

But using the global environment variable as stated above does not seem to work still

Answer 2

Using the environment variable SPRING_CLOUD_DEPLOYER_KUBERNETES_IMAGE_PULL_SECRET also didnt work for me.

An alternative that made it work in my case is adding the following to the application.yaml of the SCDF Server in Kubernetes:

application.yaml

[...]
command: ["java", "-jar", "spring-cloud-dataflow-server.jar"]
args:
  - --spring.cloud.dataflow.task.platform.kubernetes.accounts.default.imagePullSecret=<your_secret>
[...]

or, when you are using a custom SCDF image like i do, you can of course specify it as argument:

deployment.yaml

 [...] command: ["java", "-jar", "spring-cloud-dataflow-server.jar"] args: - --spring.cloud.dataflow.task.platform.kubernetes.accounts.default.imagePullSecret=<your_secret> [...]
