Download or clone the GitHub repository
Download or clone the following GitHub repository: https://github.com/CAST-Extend/com.castsoftware.imaging.kubernetessetup/tree/main
Ensure you obtain the version you want to install by changing to the correct branch:
Installation process
First create a Kubernetes namespace (for example "imaging") where you want to install CAST Imaging (see https://kubernetes.io/docs/reference/generated/kubectl/kubectl-commands#-em-namespace-em-):
kubectl create ns imaging
Now create a configmap (see https://kubernetes.io/docs/reference/generated/kubectl/kubectl-commands#-em-configmap-em-) for the .CSV files required by CAST Imaging:
kubectl create configmap defaultcsvs --from-file=tools/csv -n imaging
Run the following Helm command from the root folder of the cloned/downloaded GitHub repository to install CAST Imaging to the imaging namespace (change this if you have called your namespace something else), and pull the images from Docker hub. Ensure you change <version> to match the release number of CAST Imaging you would like to install:
helm install imaging --namespace imaging --set version=<version>
CAST Imaging will then download and install. When installed you should run the following command from the root folder of the cloned/downloaded GitHub repository to prepare CAST Imaging to accept application data:
kubectl cp tools/csv/* neo4j-core-0:/var/lib/neo4j/import -n imaging
You may then need to use the expose command (see https://kubernetes.io/docs/reference/generated/kubectl/kubectl-commands#expose):
kubectl expose deployment server --name=loadbalancer --port=80 --target-port=80 --type=LoadBalancer -n imaging
Additional commands
Update individual "service" image
Ensure you change <version> to match the release number of CAST Imaging you would like to update to. Change namespace to your chosen namespace:
helm upgrade imaging --namespace imaging --set serviceImage.tag=<version>
Update individual "etl" image
Ensure you change <version> to match the release number of CAST Imaging you would like to update to. Change namespace to your chosen namespace:
helm upgrade imaging --namespace imaging --set etlImage.tag=<version>
Update individual "neo4j" image
Ensure you change <version> to match the release number of CAST Imaging you would like to update to. Change namespace to your chosen namespace:
helm upgrade imaging --namespace imaging --set neo4jImage.tag=<version>
Get pods and service in kubernetes
kubectl get pods -n imaging kubectl get svc -n imaging
