Chapter 3. Installing the all-in-one Red Hat OpenStack Platform environment

Procedure

1. Create a non-root user on the all-in-one host:

   [root@all-in-one]# useradd stack

2. Set the password for the stack user:

   [root@all-in-one]# passwd stack

3. Disable password requirements for the sudo command for stack user:

   [root@all-in-one]# echo "stack ALL=(root) NOPASSWD:ALL" | tee -a /etc/sudoers.d/stack
   [root@all-in-one]# chmod 0440 /etc/sudoers.d/stack

4. Log in as the non-root user on the all-in-one host:

   $ ssh stack@<all-in-one>

5. Register the machine with Red Hat Subscription Manager. Enter your Red Hat subscription credentials at the prompt:

   [stack@all-in-one]$ sudo subscription-manager register

6. Attach your Red Hat subscription to the entitlement server:

   [stack@all-in-one]$ sudo subscription-manager attach --auto

   Note

   The --auto option might not subscribe you to the correct subscription pool. Ensure that you subscribe to the correct pool, otherwise you might not be able to enable all of the necessary repositories for this installation. Use the subscription-manager list --all --available command to identify the correct pool ID.

7. Lock the undercloud to Red Hat Enterprise Linux 8.4:

   $ sudo subscription-manager release --set=8.4

8. Enter the following commands to install dnf-utils, disable all default repositories, and then enable the necessary repositories:

   [stack@all-in-one]$ sudo dnf install -y dnf-utils
   [stack@all-in-one]$ sudo subscription-manager repos --disable=*
   [stack@all-in-one]$ sudo subscription-manager repos \
   --enable=rhel-8-for-x86_64-baseos-eus-rpms \
   --enable=rhel-8-for-x86_64-appstream-eus-rpms \
   --enable=rhel-8-for-x86_64-highavailability-eus-rpms \
   --enable=ansible-2.9-for-rhel-8-x86_64-rpms \
   --enable=openstack-16.2-for-rhel-8-x86_64-rpms \
   --enable=fast-datapath-for-rhel-8-x86_64-rpms

   Note

   The all-in-one environment is a Technology Preview feature in Red Hat OpenStack Platform 16.

9. Set the container-tools module version:

   [stack@all-in-one]$ sudo dnf module disable -y container-tools:rhel8
   [stack@all-in-one]$ sudo dnf module enable -y container-tools:3.0

10. Update the base operating system and reboot the system:

    [stack@all-in-one]$ sudo dnf update
    [stack@all-in-one]$ sudo reboot

11. Log back in to the host after the reboot.

12. Install the TripleO command line interface (CLI):

    [stack@all-in-one]$ sudo dnf install -y python3-tripleoclient
