Context Attributes Reference

This table lists all the attributes supported by the context packages.

Attribute	Description
START_SCRIPT	Script executed on machine boot. The attribute may contain a shebang if not calling a default shell script. Example: START_SCRIPT="yum upgrade" or START_SCRIPT="choco upgrade all" for Bash and PowerShell respectively.
START_SCRIPT_BASE64	Same as START_SCRIPT, but encoded in Base64.
TOKEN	Set to YES to create a token.txt file for OneGate monitoring.
ONEGATE_ENDPOINT	Listening address of the OneGate server. Automatically added by OpenNebula if TOKEN is YES. Defaults to http://169.254.16.9:5030. Value loaded from /etc/one/oned.conf.
NETWORK	Set to YES to automatically fill networking parameters for each NIC, used by Contextualization packages.
NETCFG_TYPE	Network configuration service inside guest VM responsible for configuring NICs. Possible values: empty (autodetects suitable service inside VM), bsd (for FreeBSD network configuration), interfaces (for Debian-style configuration via /etc/network/interfaces), netplan (for Netplan; set custom Netplan renderer via NETCFG_NETPLAN_RENDERER), networkd (for systemd-networkd), nm (for NetworkManager), scripts (for legacy Red Hat-style configuration via ifcfg-ethX files).
NETCFG_NETPLAN_RENDERER	Netplan renderer (effective only when NETCFG_TYPE=netplan): empty or networkd (for systemd-networkd), NetworkManager (for NetworkManager).
SET_HOSTNAME	Sets the VM hostname.
DNS_HOSTNAME	Set to YES to set the VM hostname to the reverse DNS name (from the first IP).
DNS	Specific DNS server for the Virtual Machine.
USERNAME	User to be created in the guest OS. Defaults to root if password or SSH_PUBLIC_KEY is defined.
CRYPTED_PASSWORD_BASE64	Crypted password encoded in base64, to be set for the USERNAME.
PASSWORD_BASE64	Password encoded in base64, to be set for the USERNAME.
CRYPTED_PASSWORD	Crypted password to be set for the USERNAME. Use CRYPTED_PASSWORD_BASE64 instead.
PASSWORD	Password to be set for the USERNAME. Use PASSWORD_BASE64 instead.
SSH_PUBLIC_KEY	Key to be added to USERNAME authorized_keys file or root if USERNAME is not set. Requires OpenSSH server on Windows, user automatically detected. USERNAME ignored.
TIMEZONE	Time zone to set. On Linux, the name must match the zone file name relative to /usr/share/zoneinfo/ (e.g. US/Central). On Windows, the name must match supported zone listed by tzutil /l (e.g. Central Standard Time).
GROW_ROOTFS	If set to NO, disables automatic growing of root filesystem or C: on Windows.
GROW_FS	Mountpoints on Linux (e.g.: /mnt/disk /data) or drive letters on Windows (e.g.: X: Y:) of extra filesystems to extend. The rootfs / on Linux or C: on Windows is implied if GROW_ROOTFS is empty or YES.
IGNORE_SWAP	If set to YES, one-contexd service skips auto-mounting of any found swap devices (does not affect swap defined in /etc/fstab).
RECREATE_RUN	If set to YES, restores missing directories and files persisted in the image in /run (or /var/run) to the ephemeral /run (or /var/run) of the VM instance.
