Configuring Schema

Schema can be configured to be deployed to kubernetes and managed by infra manager. Behaviour is controlled by k8s-propagation property in the infra-mgr-config.yml file. These are the possible values for this property:

• off - No synchronization will be done
• deny - No synchronization will be done and associated namespece will be removed from the kubernetes
• sync - Synchronizes repository changes with kubernetes
• rule - Synchronizes repository changes with kubernetes. Also monitors resource changes in kubernetes and brings them back to repository state

Creating new namespace

1. Create a new branch based on master
2. Make all the wanted changes in the CRs.
3. If you want to add new component make sure to include it in links-live.yml, dictionary-links.yml, codec-links.yml (if needed) link files are placed in links directory.
4. If you are going to have several namespaces together, make sure to assign each component in each namespace with unique nodePort. (nodePorts must be unique across the namespaces too)components that require nodePort are: rpt-data-provider, rpt-data-viewer, act, check1. Following ports are reserved by th2-infra: rmq ampq protocol: 32000, cassandra cql: 32010, ingress: 30000.
5. Make sure that k8s-propagation property in infra-mgr-config.yml file is set to sync (only branches that have this property set to sync or rule will be deployed by infra manager).
6. commit all new branch to git. (After committing new namespace will be created automatically, it might take 20-40 seconds)

Restarting existing namespace

There are two methods to restart the namespace

Repository only method

1. set k8s-propagation property to deny in infra-mgr-config.yml. Namespace will be deleted by infra manager during 30-60 secs.
2. set k8s-propagation property to sync or rule in infra-mgr-config.yml. Schema will be deployed by infra manager during 30-60 secs.

Involving kubernetes

1. set k8s-propagation property in infra-mgr-config.yml to rule and commit this change.
2. delete existing namespace using kubectl delete namespace NAMESPACE_NAME command. Schema will be redeployed automatically after 30-60 secs

Restarting single component

in order to restart single component just delete pod of that specific component using kubectl delete pod POD_NAME -n POD_NAMESPACE command or using kubernetes dashboard (if you have necessary privileges). After deleting, pod will be recreated automatically.
