Mitaka Series Release Notes¶
Added the ability to manage the memcached servers for keystone_authtoken in ironic::api
This is the first Mitaka release for puppet-ironic module.
Add api_paste type/provider.
Allow to deploy Ironic API in WSGI with Apache.
Use dnsmasq dhcp-sequential-ip flag in dnsmasq.conf Introspection naturally happens in large bulks, after which it’s inactive. Small pool for DHCP addresses means that we’ll have conflicts due to how dnsmasq distributes them by default - using hashing. This change tells dnsmasq to allocate IP addresses sequentially instead to avoid these conflicts. The drawback of this option is that long-running clients may switch IP addresses if their lease expires. This is not a concern for short introspection process.
Allow sending random kernel arguments to the IPA. IPA accepts plenty of kernel arguments, adding all them explicitly may be not practical. New option ramdisk_kernel_args allows to set a string to append to the kernel command line when booting IPA. One of the use-cases is ipa-inspection-benchmarks option, enabling benchmarking during inspection.
Allow changing list of processing hooks. Processing hooks are ironic-inspector plugins for the data processing pipeline. This change enables appending new hooks to the default list.
Specify SELinux type context for tftp dir. We create a /tftpboot/ dir in the root directory without specifying a SELinux type context, so it gets default_t. The tftp process is not allowed read permission on default_t, and as a result the ironic-inspector-dnsmasq service fails to start. The fix is to specify a type context of tftpdir_t when creating the /tftpboot/ directory. This feature pulls the /tftpboot/ directory out of the if block relating only to tftp configuration. The /tftpboot/ directory is also used by iPXE/http for the undionly.kpxe chainloading image.
Enable changing list of inspection collectors. Inspection collectors are IPA plugins that collect additional information for inspection. This feature allow changing their list, with default remaining the same (for now).
Allow to create Keystone resources to deploy Ironic Inspector, like service, endpoints, etc.
Create a separate class for configuring logging.
Support of PyMySQL driver for MySQL backend.
Release notes are no longer maintained by hand, we now use the reno tool to manage them.
cluster_id parameter is deprecated.
Use identity_uri and auth_uri by default and remove old deprecated auth parameters.
Remove QPID messaging support. Qpid messaging driver is removed from oslo.messaging so we won’t support anymore.
