Deleting items in the CLI

When you’re done with a VM, you’ll want to remove the floating IP and return it to the pool if you aren’t going to reuse it. Then you can delete an instance you no longer need.

We’re providing instructions for deleting routers, subnets, and networks, as well, though you can keep those and reuse them. Network infrastructure does not incur any SU charges to leave though it will count against Openstack resource quotas.

Conserve floating IP addresses.

There are a very limited number of IPs available to Jetstream2 users. Please return any you are not using!

Clean up what was created above	OpenStack Command
Remove the public IP address from the instance	openstack server remove floating ip your-unneeded-instance your.ip.number.here
Return the public IP address to the pool of IP numbers	openstack floating ip delete your.ip.number.here
Delete an instance	openstack server delete your-unneeded-instance

Note

You often want to create infrastructure such as networks, subnets, routers, security groups/rules, etc. only once and not delete them.

These entities are reusable by all members of your project except for any keypairs you’ve created.

Clean up other entities	Openstack Command
Deleting network infrastructure
Disconnect the router from the gateway	openstack router unset --external-gateway my-router-name
Delete the subnet from the router	openstack router remove subnet my-router-name my-subnet-name
Delete the router	openstack router delete my-router-name
Delete the subnet	openstack subnet delete my-subnet-name
Delete the network	openstack network delete my-network-name
Deleting security infrastructure
Delete a security group rule	openstack security group delete secgroup-rule-name
Delete a security group	openstack security group delete secgroup-name
Deleting other items
Deleting a keypair	openstack keypair delete my-keypair-name
