replace the image value in kubernetes yaml.

Hi,

I have created  a  bitbucket pipeline like below and now able to push image to container registry with build number as tag.

But failing to pull the same image in kubernetes deployment yml.

pipeline.yml

steps:
- step: &Build
name: Build and publish docker image.
services:
- docker # Enable Docker for your repository
image: maven:3.6.1-jdk-8
script:
- mvn -DskipTests -B package # -B batch mode makes Maven less verbose
- export IMAGE_NAME=$REGISTRY_NON_PROD/$SERVICE_NAME:${BITBUCKET_BUILD_NUMBER}
- docker login -u $DOCKER_HUB_USER -p $DOCKER_HUB_PASSWORD $REGISTRY_NON_PROD
- docker build -t $REGISTRY_NON_PROD/$SERVICE_NAME:${BITBUCKET_BUILD_NUMBER} .
- docker push $IMAGE_NAME

- step: &Deploy
image:
name: atlassian/default-image:2
name: Deploy Image
trigger: manual
script:
- sed -i "s|{{image}}|$IMAGE_NAME|g" aks-deployment.yaml
- pipe: microsoft/azure-aks-deploy:1.0.2
variables:
AZURE_APP_ID: $AZURE_APP_ID
AZURE_PASSWORD: $AZURE_PASSWORD
AZURE_TENANT_ID: $AZURE_TENANT_ID
AZURE_AKS_NAME: $AZURE_AKS_NAME
AZURE_RESOURCE_GROUP: $AZURE_RESOURCE_GROUP
KUBECTL_COMMAND: 'apply'
KUBECTL_ARGUMENTS: '-f aks-deployment.yaml'




aks-deployment.yaml

containers:
- name: containername
image: {{image}}
imagePullPolicy: IfNotPresent


on trying to deploy this am getting error like 

'The CronJob "jobname" is invalid: spec.jobTemplate.spec.template.spec.containers[0].image: Required value'

Can someone please help with this.
Thanks in advance !

Hi @Reethu

Thank you for your question!

To make image name flexible try envsubst (the program substitutes the values of environment variables) instead:

 

- envsubst < aks-deployment.yaml.template > aks-deployment.yaml

Add to your repository template aks-deployment.yaml.template file:

containers:
    - name: containername
image: ${IMAGE_NAME}
imagePullPolicy: IfNotPresent

Note! Make sure that ${IMAGE_NAME} exists in the step environment.

Also, good example provided in example-google-gke-kubectl-run repository.

 

Cheers,
Oleksandr Kyrdan
