 # Goal
 
 - autoscaling workers depending on repositories to load and allocated resources.
 
 # keda
 
 This uses KEDA - K(ubernetes) E(vents)-D(riven) A(utoscaling):
 ```
 $ helm repo add kedacore https://kedacore.github.io/charts
 $ helm repo update
 swhworker@poc-rancher:~$ kubectl create namespace keda
 namespace/keda created
 swhworker@poc-rancher:~$ helm install keda kedacore/keda --namespace keda
 NAME: keda
 LAST DEPLOYED: Fri Oct  8 09:48:40 2021
 NAMESPACE: keda
 STATUS: deployed
 REVISION: 1
 TEST SUITE: None

+# Install
+
 Install the worker declaration from this directory in the cluster
 ```
 $ export KUBECONFIG=export KUBECONFIG=staging-workers.yaml
 $ TYPE=git; REL=workers-$TYPE; \
   helm install -f ./loader-$TYPE.staging.values.yaml $REL ../worker
 $ TYPE=pypi; REL=workers-$TYPE; \
   helm install -f ./loader-$TYPE.staging.values.yaml $REL ../worker
 ```
 
 Where:
 ```
 $ cat ../loader-git.staging.values.yaml
 # Default values for worker.
 # This is a YAML-formatted file.
 # Declare variables to be passed into your templates.

 # Upgrade
 
-When changing something, apply the upgrade to the deployed chart:
+When adapting the worker definition, you can apply the changes by upgrading the
+deployed application:
+
 ```
 $ TYPE=git; REL=workers-$TYPE; \
   helm upgrade -f ./loader-$TYPE.staging.values.yaml $REL ../worker
 ```
 
-# secrets
+# Secrets
 
-This now uses metadata fetcher credentials `metadata-fetcher-credentials` installed as
-secret within the cluster.
+The current work requires metadata fetcher credentials `metadata-fetcher-credentials`
+installed as secret within the cluster.
