4.3.0, 2022-06-25

Added

  • All configurations files for the host (/etc/exports, /etc/dhcpd.conf, /etc/hosts) are now populated from the (OVERLAYDIR/host/etc/{exports|dhcpd|hosts}.ww . Also other configuration files like prometheus.yml.ww or slurm.conf.ww which depend on the cluster nodes can be placed. Also the new templated functions {{ abort }}, {{ IncludeBlock }} abd {{ no_backup }} are allowed now.
  • nodes and profiles can now have multiple system and runtime overlays, as a comma separated list. The overlays of the profile and the nodes are combined.
  • simple ipv6 support is now enabled. In warewulf.conf the option ipaddr6/Ipv6net must be set to enable ipv6. If enabled on of these options is set a node will get a derived ipv6 in the scheme ipv6net:ipaddr4. This address can also be overwritten for every node
  • Multiple files can now created from a single template.ww file with the {{ file FILENAME }} command in the template. The command is expanded to the magic template command {{ /* file FILENAME */}} which is picked up by wwctl and everything which comes after this magic comment will be written to the file FILENAME. This mechanism is leveraged in the configuration files for the network, see ifcfg.xml.ww and ifcgf.ww.
  • Networks can now have arbitrary keys value pairs in the profiles and on the node, so that things like bridges and mtu sizes can be set
  • oci container tar balls can be imported with the 'file://$PATH' scheme
  • uids and gids of a container can now get synced at import time, so that at least users with the same name have the same uid. This is not necessarily needed for warewulf, but services like munge.

Changed

  • Provision interface is not tied to 'eth0' any more. The provision interface must be have the 'primary' flag now. The file `nodes.conf' must be changed accordingly.
  • the provisioning network is now called primary and not default
  • Creating of '/etc/exports' can now be disabled, so that wwctl configure -a wont overwrite a existing '/etc/exports'.
  • The yaml format for nodes has now sub-keys for ipmi and kernel, old nodes.conf files have to to be changed accordingly
  • host overlays can globaly disbaled, but are enabled per default
  • wwctl overlay build -H will only build the overlays which are assigned to the nodes

  • warewulfd can reload config on SIGHUP and when the config file changes
  • Node database index to improve lookup speeds

  • Installed container directory is deleted when import fails

Fixed

  • Importing containers from directory
  • Debug log verbosity option takes precedence over verbose option
  • wwctl node list -n output is formatted corectly
  • Container names can contain an underscore
  • wwctl overlay build --all does not require an argument
