I'm new AKS, ACR, and DevOps Pipelines and I'm trying to setup a CI/CD pipeline.
I have a resource group setup that has both AKS and ACR in it. AKS is using Standard_B2s and only one node at this point since I'm just playing around.
Images are being deployed to ACR automatically on a commit to master--haven't figured out how to setup testing yet--but when it comes to deploying to AKS, I just keep getting a:
##[error]error: deployment "client-deployment" exceeded its progress deadline
I've changed my client.yaml to include a progressDeadlineSeconds of like an hour as 10, 15, and 20 minutes didn't work:
apiVersion: apps/v1
kind: Deployment
metadata:
name: client-deployment
spec:
progressDeadlineSeconds: 3600
replicas: 1
selector:
matchLabels:
component: client
template:
metadata:
labels:
component: client
spec:
containers:
- name: client
image: testappcontainers.azurecr.io/testapp-client
ports:

---
apiVersion: v1
kind: Service
metadata:
name: client-cluster-ip-service
spec:
type: ClusterIP
selector:
component: client
ports:
- port: 3000
targetPort: 3000
I've just been modifying the azure-pipelines.yml that Pipelines generated for me, which I currently have as the following:
# Docker

# https://docs.microsoft.com/azure/devops/pipelines/languages/docker

回答1:
Error from server (BadRequest): container "client" in pod "client-deployment-5688bdc69c-hxlcf" is waiting to start: trying and failing to pull image
Based on my experience, this is more relative with imagePullSecrets and the Kubernetes namespace.
In your Create imagePullSecret and Deploy to Kubernetes cluster task, I saw that you did not provide the value to task parameter: namespace. This will lead to a new namespace which name is default will be created, since you unspecified the namespace.
And, the kubernetes secret which generated by createSecret action is seperated for each namespace. In one word, different namespace has different secret value:
Secrets are stored within a given namespace and can only be accessed by pods within the same namespace.
Now, let’s back to your build compile process.
In your yml definition, Create imagePullSecret will create a secret for new namespace default which created by task automatically as you did not provide the given namespace value.
Then, in next task Deploy to Kubernetes cluster, because of the same reason, here the task will re-created a another new namespace default(Note: this is not same with the previous one). Also, you could see this progress from the log:
At this time, the secret that generated from the previous task will not available for the current namespace. BUT, as you know, the ACR is a private container registry which our system must verify whether the kubernetes secret is available.
In addition, in your Deploy to Kubernetes cluster task, you were specifying the repository as $(imageRepository) which does not same with the repository you push the image to $(imageRepository)-client.
This can also be checked in your log:
That's why there's no available node in your kubernetes, and you failed to pull the image also.
To avoid the issue, please ensure you provide the namespace value in KubernetesManifest@0 task.
- task: KubernetesManifest@0
displayName: Create imagePullSecret
inputs:
action: createSecret
secretName: $(imagePullSecret)
namespace: $(k8sNamespace)
dockerRegistryEndpoint: $(DRServiceConnection)
- task: KubernetesManifest@0
displayName: Deploy to Kubernetes cluster
inputs:
action: deploy
namespace: $(k8sNamespace)
manifests: |
$(System.ArtifactsDirectory)/manifests/deployment.yml
imagePullSecrets: |
$(imagePullSecret)
containers: |
$(containerRegistry)/$(imageRepository)-client:$(tag)
secret to imagePullSecrets of each namespace
回答2:
I faced a similar issues even provided the namespace still get error "exceeded its progress deadline Waiting for deployment "XX-service" rollout to finish: 0 of 1 updated replicas are available..."
due to fail to pull image
Adding "imagePullPolicy: Always" in .yaml fixed my rollout pull issues
