I have two variable containing my namespaces names:
$KUBE_NAMESPACE_DEV ="stellacenter-dev"
$KUBE_NAMESPACE_STAGE "stellacenter-stage-uat"
Now I want to modify the following .gitlab-ci.yaml configuration to include the namespace logic:
deploy_dev:
stage: deploy
image: stellacenter/aws-helm-kubectl
before_script:
- aws configure set aws_access_key_id ${DEV_AWS_ACCESS_KEY_ID}
- aws configure set aws_secret_access_key ${DEV_AWS_SECRET_ACCESS_KEY}
- aws configure set region ${DEV_AWS_DEFAULT_REGION}
script:
- sed -i "s/<VERSION>/${CI_COMMIT_SHORT_SHA}/g" provider-service.yml
- mkdir -p $HOME/.kube
- cp $KUBE_CONFIG_DEV $HOME/.kube/config
- chown $(id -u):$(id -g) $HOME/.kube/config
- export KUBECONFIG=$HOME/.kube/config
- kubectl apply -f ./provider-service.yml
only:
- developer
Provide-service.yml file
apiVersion: apps/v1
kind: Deployment
metadata:
name: provider-app
namespace: "stellacenter-dev" or "stellacenter-stage-uat"
labels:
app: provider-app

I don't know how to integrate the variables and the values correctly . I'm facing the error while I run pipeline.Kindly help me to sort it out.
You can remove the namespace: NAMESPACE from the manifest, and apply the resource in a namespace using the commandline.
- kubectl apply -f ./provider-service.yml -n ${KUBE_NAMESPACE_DEV}
- kubectl apply -f ./provider-service.yml -n ${KUBE_NAMESPACE_STAGE}
Just add one line above the apply command
- export KUBECONFIG=$HOME/.kube/config
- kubectl apply -f ./provider-service.yml
using sed you can replace the respective variable into YAML file
sed -i "s, NAMESPACE,$KUBE_NAMESPACE_DEV," Provide-service.yml
Inside that YAML file keep it something like
apiVersion: v1
kind: Service
metadata:
name: provider-service
namespace: NAMESPACE
spec:
type: NodePort
You can keep one variable instead of two for Namespace management however using the sed you can set the Namespace into the YAML and apply that YAML.
While inside your repo it will be like a template, when CI will run NAMESPACE will get replaced by sed command and YAML will get applied to k8s. Accordingly, you can also keep other things as templates and replace them with sed as per need.
apiVersion: v1
kind: Service
metadata:
name: SERVICE_NAME
namespace: NAMESPACE
spec:
type: SERVICE_TYPE
