A packer template to build an AMI for a jambonz SBC RTP server. The base linux distro is Debian 11 (bullseye).
To build an amd64 image:
$ packer build -color=false template.json
To build an arm64 image:
$ packer build -color=false \
--var="ami_base_image_arch=arm64" \
--var="instance_type=t4g.xlarge" \
template.json
There are many variables that can be specified on the packer build command line; however defaults (which are shown below) are appropriate for building an "all in one" jambonz server, so you generally should not need to specify values.
