Unreleased

Added

• New man page for defaults.conf #593

[4.4.0rc2] 2022-12-09

Added

• The environment variable WW_CONTAINER_SHELL is defined in a wwctl container shell environment to indicate the container in use. #579
• Network interface configuration (ifcfg) files now include the interface name and type. #574

Fixed

• Work-around for older versions of gzip that lack a --keep flag during wwctl container build. #580
• The default ipxe template is once again specified as a built-in default and in defaults.conf. #581
• wwctl container list no longer segfaults when a container chroot is present without a built image. #585
• wwctl configure hostfile now correctly detects the presence of the hostfile overlay template. #571
• wwctl overlay build no longer panics when rendering an template for a node which has tags set. #568
• Minor typographical fixes. #569

[4.4.0rc1] 2022-10-27

Added

• iPXE binaries included with Warewulf now support VLAN tagging. #563
• wwctl container list now shows the container creation date, modification date, and size. #537
• wwctl node edit supports directly editing or defining node configuration YAML in an editor. #540
• wwctl node export and wwctl node import support importing and exporting node definitions as YAML or (for import) CSV. The CSV file must have a header in where the first field must always be the nodename, and the rest of the fields are the same as the long commandline options. Network device must have the form net.$NETNAME.$NETOPTION. (e.g., net.default.ipaddr) #540
• The warewulfd.service systemd unit file now supports execreload and execstop. #550
• Network interfaces now accept an mtu attribute. #549
• The wwinit overlay now supports network interface configuration via NetworkManager for Ethernet and InfiniBand interfaces. #539
• Default node attribute values (e.g., for kernel arguments) are now read in from a defaults.conf configuration file. If this file is not present, built-in default values are used. #539
• Warewulf documentation is now managed alongside the Warewulf source code in a single code repository so that documentation may be updated alongside code changes.
• New man pages for warewulf.conf and nodes.conf #510
• An initial cut of the Warewulf API #471
• wwctl show --render shows overlay templates as they would be rendered on a given target node. #467
• wwctl ssh now supports Bash completion. #466

Changed

• wwctl overlay edit no longer saves a new template to the overlay if the template is not modified from its initial state. #522
• The wwinit overlay now only sets a name for a network interface if that interface has a MAC address defined. #553
• wwctl container delete now also deletes the built images associated with that container. #214
• Unified internal code paths for wwctl profile and wwctl node commands, and between the on disk YAML format and the in memory format, enabling the command-line options to be autogenerated from the datastructures and ensuring that profile and node capabilities remain in sync. #495
• wwctl power commands no longer separates node output with additional whitespace. #514

Fixed

• /etc/warewulf/excludes (read from the node image) once again excludes files from being included in the node image. #532
• wwctl ssh always uses a node's primary interface. #544
• wwctl container show now correctly shows the kernel version. #542
• System users are no longer prevented from logging into compute nodes. #538
• wwctl overlay chown now correctly handles uid and gid arguments. #530
• wwctl overlay chown no longer sets gid to 0 when unspecified. #531
• Corrected the path for .wwbackup files in some situations. #524
• Bypass imgextract for legacy BIOS machines to avoid 32-bit memory limitations. #497
• warewulfd no longer panics when network interface tags are defined. #468
• The wwinit overlay now configures the network device type. #465
• Minor typographical fixes. #528, #519

[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

[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
• iPXE binaries updated
• Installed container directory is deleted when import fails
• Default iPXE script now reboots erroring nodes every 15 seconds
• Only open /etc/hosts when writing

Removed

• wwctl configure --persist flags have been removed. configure commands persist changes by default unless --show is used
• In-repository documentation: has been moved to it's own repository

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
• 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
