#Provisioner for k8s objects:

##Capabilities
a) generic type
⋅ designed for objects which are declarative and kubernetes can run rolling update on them
⋅ run kubectl apply on changed objects
⋅ ideal for deployments
⋅ ideal for "one time creation" objects like svc

b) secrets type
⋅ designed for secrets
⋅ after secret change, secret is recreated and kubectl patch is triggered on deployments which are using them. this triggers rolling update on these deployments
⋅ secrets are not recreated after startup to avoid unnecessary rolling updates

c) configmap type
⋅ designed for configmaps
⋅ after configmaps change, configmap is recreated and pods which are using this configmap are deleted
⋅ configmap are not recreated after startup to avoid unnecessary rolling updates

d) quota type
⋅ designed for creating namespaces nad quotas
⋅ after namespace/quota change kubectl apply is executed on changed file, to ensure proper state

d) force-update
⋅ create all objects from repository

#Force update on all objects
To recreate all objects exec into pod and run

bash /provisioners/force-update.sh

##Configuration:

###example definition is in deploy directory of this repository
