Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[Unreleased]

Changed

  • Provision interface is not tied to 'eth0' any more. The provision interface must be named 'default' now. The file `nodes.yaml' must be changed accordingly.
  • Creating of '/etc/exports' can now be disabled, so that wwctl configure -a wont overwrite a existing '/etc/exports'.
  • 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 file 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.

[4.1.0] - 2021-07-29

Added

  • Support for ARM nodes
  • firewalld service file for warewulfd
  • -y option to skip "Are you sure" queries
  • wwctl kernel delete command
  • wwctl vnfs alias for wwctl container
  • Support for authenticated OCI registries
  • warewulfd can reload config on SIGHUP and when the config file changes
  • Node database index to improve lookup speeds
  • Kernels and containers can be imported from a chroot subdirectory
  • Systemd service file

Changed

  • wwctl node list output beautification
  • Log timestamps are more precise
  • PID file and log files are now in /var/run and /var/log, respectively
  • make install no longer overwrites preexisting configuration files
  • Kernel modules and overlays are now compressed
  • rootfstype now uses rootfs in default kernel arguments

  • Installed container directory is deleted when import fails
  • Default iPXE script now reboots erroring nodes every 15 seconds

  • wwctl node list -n output is formatted corectly
  • Container names can contain an underscore
  • wwctl overlay build --all does not require an argument
  • specfile date format works with older versions of rpmbuild
  • Use SystemOverlay when building system overlay
  • dhcpd template now references correct wwctl subcommand
  • wwctl node set kernelargs and wwctl profile set kernelargs change kernel arguments
