The vast majority of configurations for the environment are stored
in config_${user}.sh. You can manipulate the values of some
environment variables with allowed values as in this table and it is
recommended modifying or adding variables in config_${user}.sh config
file instead of exporting them in the shell. By doing that, it is
assured that they are persisted.

NOTE (BMO/CAPI/CAPM3/IPAM)RELEASE variables are also affecting the
BRANCH variables so make sure that RELEASE and BRANCH variables are
not conflicting.
The use of local IPA enabled via USE_LOCAL_IPA is only supported on
Ubuntu host when EPHEMERAL_CLUSTER is kind cluster and Ironic is
directly deployed to the OCI runtime (no K8s pod)
Environment variables with _LOCAL_IMAGE in their name are used to
specify directories that contain the code to build the components
locally e.g. CAPM3_LOCAL_IMAGE.
By default two libvirt networks are created external and provisioning
but in some circumstances it can be useful to define additional secondary
networks.
This can also be enabled via environment variables, the
EXTRA_NETWORK_NAMES variable defines a list of network names,
and then ipv4, ipv6 or dual stack subnets can be defined as in the
following example (note that the name prefix in the subnet variables
is always uppercase, even if the EXTRA_NETWORK_NAMES are lowercase):
export EXTRA_NETWORK_NAMES="nmstate1 nmstate2"
export NMSTATE1_NETWORK_SUBNET_V4='192.168.221.0/24'
export NMSTATE1_NETWORK_SUBNET_V6='fd2e:6f44:5dd8:ca56::/120'
export NMSTATE2_NETWORK_SUBNET_V4='192.168.222.0/24'
export NMSTATE2_NETWORK_SUBNET_V6='fd2e:6f44:5dd8:cc56::/120'By default, we pin downloaded binaries and packages with SHA256 digests.
For testing purposes, verification of the digests will be skipped if
INSECURE_SKIP_DOWNLOAD_VERIFICATION is set to true.
