A Packer project to build the virtual machine images of the SIP Media Gateway stack.
Install Packer using this tutorial.
The credentials that allows Packer to connect to the Openstack cluster should be passed as environment variables:
OS_AUTH_URL: URL of the Openstack endpoint.OS_USERNAME: name of the Openstack user.OS_PASSWORD: password of the Openstack user.OS_REGION_NAME: name of the Openstack region.OS_PROJECT_DOMAIN_ID: ID of the Openstack project domain.OS_USER_DOMAIN_NAME: name of the Openstack project domain.OS_PROJECT_ID: ID of the Openstack project.OS_PROJECT_NAME: name of the Openstack project.OS_INTERFACE: Openstack interface.OS_IDENTITY_API_VERSION: version of the Openstack API.
For each service among GW_HOST, KAMAILIO, COTURN and SCALER, four environment variables should be declared in order to configure the build of the VM image:
PKR_VAR_<service>_SOURCE: name of the base OS image.PKR_VAR_<service>_FLAVOR: name of the flavor.PKR_VAR_<service>_NETWORK_ID: ID of the network (this information can be found either using the Openstack command line or directly from the dashboard).PKR_VAR_<service>_SSH_USERNAME: name of the user for the SSH connection.
In order to build all images, launch the following command:
packer build .In order to build the image of a service defined in a <service>.pkr.hcl file, launch the following command:
