Chapter 4. Configuring the all-in-one Red Hat OpenStack Platform environment

Generate the containers-prepare-parameters.yaml file that contains the default ContainerImagePrepare parameters:

[stack@all-in-one]$ sudo openstack tripleo container image prepare default --output-env-file $HOME/containers-prepare-parameters.yaml

Edit the containers-prepare-parameters.yaml file and include your Red Hat credentials in the ContainerImageRegistryCredentials parameter so that the deployment process can authenticate with registry.redhat.io and pull container images successfully:

parameter_defaults:
  ContainerImagePrepare:
  ...
  ContainerImageRegistryCredentials:
    registry.redhat.io:
      <USERNAME>: "<PASSWORD>"

Set the ContainerImageRegistryLogin parameter to true in the containers-prepare-parameters.yaml:

parameter_defaults:
  ContainerImagePrepare:
  ...
  ContainerImageRegistryCredentials:
    registry.redhat.io:
      <USERNAME>: "<PASSWORD>"
  ContainerImageRegistryLogin: true

If you want to use the all-in-one host as the container registry, omit this parameter and include --local-push-destination in the openstack tripleo container image prepare command. For more information, see Preparing container images.

Create the $HOME/standalone_parameters.yaml file and configure basic parameters for your all-in-one RHOSP environment, including network configuration and some deployment options. In this example, network interface eth1 is the interface on the management network that you use to deploy RHOSP. eth1 has the IP address 192.168.25.2:

[stack@all-in-one]$ export IP=192.168.25.2
[stack@all-in-one]$ export NETMASK=24
[stack@all-in-one]$ export INTERFACE=eth1
[stack@all-in-one]$ export DNS1=1.1.1.1
[stack@all-in-one]$ export DNS2=8.8.8.8

[stack@all-in-one]$ cat <<EOF > $HOME/standalone_parameters.yaml
parameter_defaults:
  CloudName: $IP
  CloudDomain: <DOMAIN_NAME>
  ControlPlaneStaticRoutes: []
  Debug: true
  DeploymentUser: $USER
  DnsServers:
    - $DNS1
    - $DNS2
  NeutronPublicInterface: $INTERFACE
  NeutronDnsDomain: localdomain
  NeutronBridgeMappings: datacentre:br-ctlplane
  NeutronPhysicalBridge: br-ctlplane
  StandaloneEnableRoutedNetworks: false
  StandaloneHomeDir: $HOME
  StandaloneLocalMtu: 1500
EOF

You must configure the DnsServers parameter with your DNS address. You can find this address in the /etc/resolv.conf file:

[stack@all-in-one]$ cat /etc/resolv.conf
192.168.122.1

If you use only a single network interface, you must define the default route:

ControlPlaneStaticRoutes:
  - ip_netmask: 0.0.0.0/0
    next_hop: $GATEWAY
    default: true

If you have an internal time source, or if your environment blocks access to external time sources, use the NtpServer parameter to define the time source that you want to use:

parameter_defaults:
  NtpServer: clock.example.com

If you want to use the all-in-one RHOSP installation in a virtual environment, you must define the virtualization type with the NovaComputeLibvirtType parameter:

parameter_defaults:
  NovaComputeLibvirtType: qemu

The Load-balancing service (octavia) does not require that you configure SSH. However, if you want SSH access to the load-balancing instances (amphorae), add the OctaviaAmphoraSshKeyFile parameter with a value of the absolute path to your public key file for the stack user: OctaviaAmphoraSshKeyFile: "/home/stack/.ssh/id_rsa.pub"
