Configuring target hosts
Modify the
/etc/openstack_deploy/openstack_user_config.yml
file to
configure the target hosts.
Do not assign the same IP address to different target hostnames. Unexpected results may occur. Each IP address and hostname must be a matching pair. To use the same host in multiple roles, for example infrastructure and networking, specify the same hostname and IP in each section.
Use short hostnames rather than fully-qualified domain names (FQDN)
to prevent length limitation issues with LXC and SSH. For example, a
suitable short hostname for a compute host might be:
123456-Compute001
.
Configure a list containing at least three infrastructure target hosts in the
infra_hosts
section:infra_hosts: 603975-infra01: ip: INFRA01_IP_ADDRESS 603989-infra02: ip: INFRA02_IP_ADDRESS 627116-infra03: ip: INFRA03_IP_ADDRESS 628771-infra04: ...
Replace ``_IP_ADDRESS
* with the IP address of the
br-mgmt`` container management bridge on each infrastructure target host. Use the same net block as bond0 on the nodes, for example:infra_hosts: 603975-infra01: ip: 10.240.0.80 603989-infra02: ip: 10.240.0.81 627116-infra03: ip: 10.240.0.184
Configure a list containing at least one network target host in the
network_hosts
section:network_hosts: 602117-network01: ip: NETWORK01_IP_ADDRESS 602534-network02: ...
Replace ``_IP_ADDRESS
* with the IP address of the
br-mgmt`` container management bridge on each network target host.Configure a list containing at least one compute target host in the
compute_hosts
section:compute_hosts: 900089-compute001: ip: COMPUTE001_IP_ADDRESS 900090-compute002: ...
Replace ``_IP_ADDRESS
* with the IP address of the
br-mgmt`` container management bridge on each compute target host.Configure a list containing at least one logging target host in the
log_hosts
section:log_hosts: 900088-logging01: ip: LOGGER1_IP_ADDRESS 903877-logging02: ...
Replace ``_IP_ADDRESS
* with the IP address of the
br-mgmt`` container management bridge on each logging target host.Configure a list containing at least one optional storage host in the
storage_hosts
section:storage_hosts: 100338-storage01: ip: STORAGE01_IP_ADDRESS 100392-storage02: ...
Replace ``_IP_ADDRESS
* with the IP address of the
br-mgmt`` container management bridge on each storage target host. Each storage host also requires additional configuration to define the back end driver.The default configuration includes an optional storage host. To install without storage hosts, comment out the stanza beginning with the storage_hosts: line.
