[Beta] Invenio Helm chart: Kubernetes specifics

  1. Docker credentials
  2. Routing
  3. Instance setup

Pre-requisites

Docker credentials

As you're working in a cloud environment and don't know to which node the image is pulled, you have to define an imagePullSecret:

kubectl create secret docker-registry regsecret \
  --docker-server=DOCKERHOST_CHANGEME \
  --docker-username=DOCKERUSER_CHANGEME \
  --docker-password=DOCKERPASSWORD_CHANGEME \
  --docker-email=EMAIL_CHANGE_ME \
  --namespace invenio

You need to add this secret in your values-overrides.yaml file for every place where the image is used. For example:

web:
  image: your/invenio-image
  imagePullSecret: your/image-pull-secret

Routing

Before installing you need to configure a few things in a values-overrides.yaml file.

ingress:
  tlsSecretNameOverride: your-ssl-secret

The ingress is configured using the following variables:

Parameter Description Default
ingress.enabled Whether to enable ingress true
ingress.class Class of the ingress if enabled nginx-internal
ingress.tlsSecretNameOverride The ingress ssl secret for HTTPS your-ssl-secret

Instance setup

Get a bash terminal in a pod:

kubectl get pods --namespace invenio
kubectl exec -it <web-pod> bash --namespace invenio  # <web-pod> is found with the previous command

Then you can run invenio commands and setup your instance

. scl_source enable rh-python36
invenio db init # If the db does not exist already
invenio db create
invenio index init
invenio index queue init purge
invenio files location --default 'default-location'  $(invenio shell --no-term-title -c "print(app.instance_path)")'/data'
invenio roles create admin
invenio access allow superuser-access role admin
invenio rdm-records demo
