marvinjs-helm-chart

Helm chart for running MarvinJS Webservices in a Kubernetes cluster

References

• Docker Compose recipe: ChemAxon/marvinjs-docker-example

License File

If you have a license file (instead of a license key), mount it into the container at runtime:

/home/cxnapp/.chemaxon/licenses/license.cxl

Create a secret from the file using the following:

kubectl create secret generic marvinjs-license --from-file=license.cxl

And specify this secret name as the value for controller.license.secretFile.

PSA: Always check Pod AGE after deploying

You may need to delete the running Pod to trigger a new Pod to be created with the new config.

Local

If you are running Docker + Kubernetes locally on your laptop, you can use the following to run marvinjs on your local cluster

To change the existing application in your local cluster, you can use the following command:

$ helm upgrade --install marvinjs -n staging . -f values.local.yaml

This will overwrite the configuration of the instance in your local cluster.

You should then be able to access the following URL:

• MarvinJS Demo Canvas: marvinjs.proxy.localhost/demo.html

This example is currently configured to use the NGINX Ingress Controller, but you can adjust values.local.yaml to change the ingress class.

Staging

To change the existing application in the staging namespace, you can use the following command:

$ helm upgrade --install marvinjs -n staging . -f values.staging.yaml

This will overwrite the configuration of the current staging instance.

Swagger UI is available to test the MarvinJS API individually (if desired):

• MarvinJS: marvinjs.staging.mmli1.ncsa.illinois.edu/api/swagger-ui/index.html

Prod

TBD - prod should look almost identical to staging, and will be deployed automatically by ArgoCD once the necessary pieces are in place. Prod will have the same URLs as above, just without the .staging in each

TODOs

• Create ArgoCD apps for staging + prod
