9.4. Deploy a Stack Using Orchestration Templates

Procedure 9.8. Deploying a Stack Using Orchestration Templates

1. Open the /etc/sysconfig/iptables file in a text editor.
2. Add the following INPUT rules to allow TCP traffic on ports 8003, 8000, and 8004:

   -A INPUT -i BR -p tcp --dport 8003 -j ACCEPT
   -A INPUT -i BR -p tcp --dport 8000 -j ACCEPT
   -A INPUT -p tcp -m multiport --dports 8004 -j ACCEPT

   Copy to Clipboard Toggle word wrap
   Replace BR with the interface of the bridge used by the instances launched from Orchestration templates. Do not include the -i BR parameter in the INPUT rules if you are not using nova-network, or if the Orchestration service and nova-compute are not hosted on the same server.
3. Save the changes to the /etc/sysconfig/iptables file.
4. Restart the iptables service for the firewall changes to take effect:

   # systemctl restart iptables.service

   Copy to Clipboard Toggle word wrap
5. Launch an application:

   # heat stack-create STACKNAME \
      --template-file=PATH_TEMPLATE \
   	--parameters="PARAMETERS"

   Copy to Clipboard Toggle word wrap
   Replace the following values:
   • Replace STACKNAME with the name to assign to the stack. This name will appear when you run the heat stack-list command.
   • Replace PATH_TEMPLATE with the path to your .template file.
   • Replace PARAMETERS with a semicolon-delimited list of stack creation parameters to use. Supported parameters are defined in the template file itself.
