Role documentation

collect-flavors-and-verify-profiles

Collect and verify role flavors.

This validation checks the flavors assigned to roles exist and have the correct capabilities set.

  • hosts: undercloud

  • groups: pre-deployment, pre-upgrade

  • parameters:

  • roles: collect_flavors_and_verify_profiles

Role documentation

default-node-count

Verify hypervisor statistics.

This validation checks that the nodes and hypervisor statistics add up.

  • hosts: undercloud

  • groups: pre-deployment

  • parameters:

  • roles: default_node_count

Role documentation

dhcp-provisioning

DHCP on the Provisioning Network.

An unexpected DHCP server on the provisioning network can cause problems with deploying the Ironic nodes.

This validation checks for DHCP responses on the undercloud’s provisioning interface (eth1 by default) and fails if there are any.

  • hosts: undercloud

  • groups: pre-deployment

  • parameters:

  • roles: dhcp_validations

Role documentation

ironic-boot-configuration

Check Ironic boot configuration.

Check if baremetal boot configuration is correct.

  • hosts: undercloud

  • groups: pre-deployment, pre-upgrade

  • parameters:

  • roles: ironic_boot_configuration

Role documentation

network-environment

Validate the Heat environment file for network configuration.

This validates the network environment and nic-config files that specify the overcloud network configuration and are stored in the current plan’s Swift container.

The deployers are expected to write these files themselves as described in the Network Isolation guide:

http://tripleo.org/advanced_deployment/network_isolation.html

  • hosts: undercloud

  • groups: pre-deployment

  • parameters:

    • network_environment_path: environments/network-environment.yaml

    • plan_env_path: plan-environment.yaml

    • ip_pools_path: environments/ips-from-pool-all.yaml

  • roles: network_environment

Role documentation

node-disks

Check node disk configuration.

Check node disk numbers and sizes and whether root device hints are set.

  • hosts: undercloud

  • groups: pre-deployment

  • parameters:

    • ironic_conf_file: /var/lib/config-data/puppet-generated/ironic/etc/ironic/ironic.conf

  • roles: node_disks

Role documentation

package-version

package-version.

Ensures we can access the wanted package version. Especially useful when you are switching repositories, for instance during an upgrade.

  • hosts: all

  • groups: prep, pre-deployment, pre-upgrade, pre-update, pre-system-upgrade, pre-undercloud-upgrade, pre-overcloud-prepare, pre-overcloud-upgrade, pre-overcloud-converge, pre-ceph

  • parameters:

    • package_version_debug: False

  • roles: package_version

Role documentation

switch-vlans

Compare switch port VLANs to VLANs in nic config.

LLDP data received during introspection contains the configured VLANs for each switch port attached to the nodes interfaces. Compare the VLAN IDs set on the switch port to those configured in nic config files. Since the mapping of roles to nodes isn’t known prior to deployment, this check can only check VLANs across all switch ports, not on a particular switch port.

  • hosts: undercloud

  • groups: pre-deployment

  • parameters:

    • network_environment_path: environments/network-environment.yaml

    • ironic_inspector_conf_file: /var/lib/config-data/puppet-generated/ironic_inspector/etc/ironic-inspector/inspector.conf

  • roles: switch_vlans

Role documentation

system-encoding

System encoding.

Ensure the local is unicode

  • hosts: all

  • groups: pre-deployment, pre-upgrade, pre-update

  • parameters:

    • system_encoding_debug: False

  • roles: system_encoding

Role documentation

tls-everywhere-pre-deployment

Confirm undercloud is setup correctly prior to overcloud deploy.

Checks that the undercloud has novajoin set up corectly and that we are ready to do the overcloud deploy with tls-everywhere.

  • hosts: undercloud

  • groups: pre-deployment

  • parameters:

  • roles: tls_everywhere

Role documentation

undercloud-debug

Undercloud Services Debug Check.

The undercloud’s openstack services should _not_ have debug enabled. This will check if debug is enabled on undercloud services. If debug is enabled, the root filesystem can fill up quickly, and is not a good thing.

  • hosts: undercloud

  • groups: pre-deployment

  • parameters:

    • debug_check: True

  • roles: undercloud_debug

Role documentation

undercloud-heat-purge-deleted

Verify heat-manage purge_deleted is enabled in crontab.

Without a purge_deleted crontab enabled, the heat database can grow very large. This validation checks that the purge_deleted crontab has been set up.

  • hosts: undercloud

  • groups: pre-upgrade, pre-update, pre-deployment

  • parameters:

    • cron_check: heat-manage purge_deleted

  • roles: undercloud_heat_purge_deleted

Role documentation

undercloud-process-count

Check the number of OpenStack processes on undercloud.

The default settings for OpenStack is to run one process (heat-engine, keystone, etc.) per CPU core. On a machine with a lot of cores this is both unnecessary and can consume a significant amount of RAM, leading to crashes due to OOMKiller.

  • hosts: undercloud

  • groups: pre-deployment

  • parameters:

    • max_process_count: 8

  • roles: undercloud_process_count
