The packer file and corresponding script in this folder are used
for building Eiffel projects on Nordix Jenkins.
Nordix Jenkins.

The packer file is specific to City Cloud Karlskrona region since
it contains the Karlskrona region endpoint and UUID of the network
created there. For other regions or clouds, a similar file needs
to be created. The actual script that is executed by packer on
provisioned temporary instances should work on any Ubuntu2004
regardless of cloud and region.

Eiffel projects build container images and the script
configure-image-ubuntu2004.sh installs and configures podman so
the proxy for Docker Hub setup on Nordix Container Image Registry
can be utilized.

A final note is that the file authorized_keys.packer is used for
injecting user keys into image during cloud-init phase for ssh
access to the slaves for troubleshooting. If you want to have
access to the slaves, please add your ssh public key in it.
