Deploying the Vizzy Helm Chart

This helm chart has a top level Vizzy chart, with a Postgresql chart defined as a dependency. When deploying the chart, be sure to specify a username, password, and database name for the postgresql chart.

First pick a username and password for the database and create a kubernetes secret. Be sure to include the host and post:

kubectl create secret generic vizzy-postgres-secret \
 --from-literal=host=postgres \ # optional, default is postgres
 --from-literal=port=5432 \ # optional, default is 5432
 --from-literal=database_name=vizzy \ # optional, default is vizzy
 --from-literal=username=postgres \ # required
 --from-literal=password=******** \ # required
 --from-literal=schema_search_path=public # optional, default is public

If you haven't setup the server with credentials follow the setup section on the readme.

After completing that, add another kubernetes secret for the rails master key that was generated and placed into secrets.yml.key. Do not check in the encryption key into the repository,

kubectl create secret generic vizzy-rails-master-key-secret --from-literal=token=**********************

Then you can deploy the helm chart, overriding any values necessary. Run the install with this directory using the database username and password from above.

helm install . \
    --set image.repository=scottcbishop/vizzy \
    --set image.tag=v3.1.1 \
    --set image.pullSecret=myregistrykey \
    --set env.vizzyUri.value=vizzy.com \
    --set service.type=LoadBalancer \
    --set replicaCount=1 \
    --set postgresql.postgresUser=postgres \
    --set postgresql.postgresPassword=******** \
    --set postgresql.postgresDatabase=vizzy

You could also override values in a .yaml file and then every time you want to upgrade, you can run:

helm upgrade -i -f vizzy.yaml /vizzy

where vizzy.yaml looks like

# Default values for vizzy.
# This is a YAML-formatted file.
# Declare variables to be passed into your templates.
