HOWTO remove channel or tenant
Why do that¶
An existing tenant will not use the PunchPlatform anymore, or a test tenant has to be removed for clarity purposes. This is also useful to a channel, this reulting of a deletion and a creation.
Reminder : if this is only about channel supervision, the command below dust deactivate the channel.
channelctl unconfigure mytenant/mychannel
- Channel must be in a good state, either in STARTED state or in STOPPED. The operator's pp-conf Git repository must be clean and syned to the central repository.
What to do¶
Stop any data entry in the canal if needed (e.g. stopping TCP syslog forwarding to PunchPlatform); Check that the log rates for the selected channel/tenant are null and no backlog in the PunchPlatform Grafana view;
Stop the channel (or ensure it is already stopped):
channelctl stop --channel mychannel channelctl status --channel mychannel
Unconfigure the channel :
channelctl --unconfigure mytenant/mychannel
Commit and push changes, the PunchPlatform Admin should yield the tenant or channel as .
To delete the channel, the directory of configuratio sould be removed as well :
$ rm -rf $PUNCHPLATFORM_CONF_DIR/tenants/mytenant/channels/mychannel
If you don't want to risk a wrong channel regenration, the generation manifest can be removed as well.
$ rm -rf $PUNCHPLATFORM_CONF_DIR/tenants/mytenant/configuration-for-channels-generation/[...]/mychannel.json
after the number of retention hours specified in the
punchplatform.properties file (default : 72), the Elasticsearch, CEPH
or the Kafka topics are normally empty. Is it then useless but for
clarity purposes to delete any remaining Kafka topic here, please
contact the MCO Applicative Team.
In case of a full tenant removal, ou may need to reconfigure some platform-oriented datas:
- removing a tenant-specific Storm cluster from the
punchplatform.propertiesfile; in that case do not forget to re-deploy the platform for chacking;
- removing configuration from the reverse proxy;
- Closing tenant-specific flow and destroy VMs...
