kubectl create namespace <ONELIST_NAMESPACE>
2. Create ConfigMap and Secret
These Kubernetes ConfigMap and Secret defines the required environment variables that are used by OneList services. Open the "config.yaml" in notepad and update the following fields with the actual value.
...
kubectl apply -f config.yaml --namespace <ONELIST_NAMESPACE>
3. Create the Secrete for pulling OneList images
Replace placeholders in the command below and run it.
kubectl create secret docker-registry iqx.acr --docker-server=https://iqxbusiness.azurecr.io --docker-username=<ACR_USERNAME> --docker-password=<ACR_PASSWORD> --docker-email=<YOUR_EMAIL_ADDRESS> --namespace <ONELIST_NAMESPACE>
4. Create the TLS secrete
Run the command below.
kubectl create secret tls tls.onelist --cert <SSL_CERTIFICATE_FILE> --key <PRIVATE_KEY_FILE> --namespace <ONELIST_NAMESPACE>
5. Deploy OneList containers for the apps and services
Run the 2 commands below.
kubectl appy -f onelist6-deployment.yaml --namespace <ONELIST_NAMESPACE>
kubectl appy -f onelist6-service.yaml --namespace <ONELIST_NAMESPACE>
6. Create Nginx ingress service
Run the 2 commands below.
kubectl create -f ingress-nginx-controller.yaml --namespace <ONELIST_NAMESPACE>
kubectl create -f onelist6-ingress.yaml --namespace <ONELIST_NAMESPACE>
Upgrade image version
Upgrade all applications
You need to know the namespace where OneList applications are deployed before proceeding with this upgrade. Download the upgrade.ps1 file. Run the command below, where the IMAGE_VERSION is in the format of x.x.x, e.g. 6.3.0:
powershell -f upgrade.ps1 -n <ONELIST_NAMESPACE> -v <IMAGE_VERSION>
Upgrade a single application
If image version update is required, use the command below as a template and apply proper parameters to update image version of applications.
kubectl set image deployment/onelistserver onelistserver=iqxbusiness.azurecr.io/iqx.onelist.server:v<IMAGE_VERSION> -n <ONELIST_NAMESPACE>
Parameters:
- deployment/onelistserver is the deployment name.
- onelistserver=iqxbusiness.azurecr.io/iqx.onelist.server:v6.2.2. onelistserver is the container name. iqxbusiness.azurecr.io/iqx.onelist.server:v6.2.2 is the tag of the image to be updated.
