I'm trying to use the OpenStack Nova client and create a script in order to launch an instance. I was able to create a VM with a specific key but the problem is that i can't add an existing security group to that instance.
I know how to create a security group and add some rules to it using the nova client.
Thank you in advance
After launching an instance you can add a security group to it using the CLI
nova add-secgroup my-special-server sec-group-3
See the help for more info
nova help add-secgroup
usage: nova add-secgroup <server> <secgroup>
Add a Security Group to a server.
Positional arguments:
<server> Name or ID of server.
<secgroup> Name or ID of Security Group.
Personally I would add the security group during the boot of an instance using the --security-groups
like below
nova boot --image cirros-0.3.1-x86_64-uec --flavor m1.tiny --security-groups my-sec-group
