Galaxy on Kubernetes Management (GalaxyKubeMan) Helm Chart

Helm chart for GalaxyKubeMan (GKM) used for deploying Galaxy on GKE/AnVIL.

Creating a GKE cluster and deploying dependencies

Start by launching a GKE cluster, then install the Galaxy dependencies chart that deploys necessary operators, as well as create persistent disks.

gcloud container clusters create example-gke-cluster --cluster-version="1.30" --no-enable-autorepair --disk-size=200 --num-nodes=1 --machine-type=e2-standard-16 --zone "us-east1-b"


helm repo add cloudve https://raw.githubusercontent.com/CloudVE/helm-charts/master/
helm repo update
helm install --create-namespace -n "galaxy-deps" galaxy-deps cloudve/galaxy-deps --set cvmfs.cvmfscsi.nodeplugin.priorityClassName="" --set postgresql.deploy=false

gcloud compute disks create "nfs-pd" --size 300Gi --zone "us-east1-b"
gcloud compute disks create "postgres-pd" --size 10Gi --zone "us-east1-b"

Deploying a new Galaxy instance

Once the cluster is created, you can deploy a new Galaxy instance. The sample-values.yaml file contains sample values to deploy a test/dev version with no/minimal configuration. Consider the following changes:

• If you changed the names or the persistent disks from the instructions above, just update those values in persistence.[nfs, postgres].persistentVolume.extraSpec.gcePersistentDisk.pdName;
• If you plan on changing the release name from gkm used in the helm command below, set the value of galaxy.persistence.existingDatabase to {{ release-name }}-postgresql using the string literal, and not a template variable.
• If you plan on changing the release name from gkm used in the helm command below, set the value of galaxy.persistence.galaxyExistingSecret to {{ release-name }}-postgresql using the string literal, and not a template variable.

Then run the following commands:

git clone https://github.com/galaxyproject/galaxykubeman-helm
cd galaxykubeman-helm/galaxykubeman
cp sample-auth.yaml templates/auth.yaml
helm dependency update
helm upgrade --install --create-namespace -n gkmns gkm . --values sample-values.yaml --wait --wait-for-jobs

It will take about 5 minutes for the Galaxy instance to be ready. It will be available at http://[galaxy-nginx service external IP]/galaxy/.

Note: If you will want to redeploy this instance (ie, keep the data), before deleting it, make sure to record the ID of the Galaxy PVC.

Redeploying a Galaxy instance

If you want to redeploy a Galaxy instance, meaning create a new instance but with data from an earlier installation, it is necessary to update the following values before installing the chart:

• Set restore.persistence.nfs.galaxy.pvcID to the PVC ID of the old PVC from the previous Galaxy instance;
• Set galaxy.persistence..existingClaim to {{release-name}}-galaxy-galaxy-pvc. You must use a literal string here, and not a template variable;
• Set `galaxy.persistence.storageClass to -

Then run the helm upgrade command again with the same parameters as above.

Deploying 2nd Galaxy instance on the same cluster

To deploy a second Galaxy instance on the same cluster, first add a node pool to the cluster (call is pool-2 if you want to minimize changes to the sample values) as well as create a second set of GCP persistent disks:

gcloud compute disks create "nfs-pd-2" --size 300Gi --zone "us-east1-b"
gcloud compute disks create "postgres-pd-2" --size 10Gi --zone "us-east1-b"

Sample values are available in sample-values-2nd-deployment.yaml with the necessary configurations. Consider the following values changes:

• If you changed the names of persistent disks, update persistence.[nfs, postgres].persistentVolume.extraSpec.gcePersistentDisk.pdName to the names of your GCP persistent disks;
• Set the value of galaxy.persistence.existingDatabase to {{ release-name }}-postgresql using the string literal, and not a template variable.
• Set the value of galaxy.persistence.galaxyExistingSecret to {{ release-name }}-postgresql using the string literal, and not a template variable.

Then run the following commands:

helm upgrade --install --create-namespace -n gkmns2 gkm2 . --values sample-values-2nd-deployment.yaml --wait --wait-for-jobs

It will take a few minutes for the second Galaxy instance to be ready. The instance will be deployed It will be available at http://[galaxy-nginx-2 service external IP]/galaxy/.

Leo updates

When the GKM chart version changes, need to make a PR to Leo with the updated GKM chart version, any changes to the variables being passed there.
