%\subsubsection{Register nodes for provisioning}

\noindent Next, we add {\em compute} nodes and define their properties as
attributes in \Confluent{} database.
These hosts are grouped logically into a group named {\em
compute} to facilitate group-level commands used later in the recipe. The compute
group has to be defined first before we can add any nodes to the group using the
{\texttt nodegroup define} command. Note the
use of variable names for the desired compute hostnames, node IPs, MAC
addresses, and BMC login credentials, which should be modified to accommodate
local settings and hardware. To enable serial console access via \Confluent{},
{\texttt console.method}
property is also defined.

Defining nodes one-by-one, as done above, is only efficient
for a small number of nodes. For larger node counts,
\Confluent{} provides capabilities for automated detection and
configuration.

Hardware Discovery \& Define Node Guide}.

%\clearpage
If enabling {\em optional} IPoIB functionality (e.g. to support Lustre over \InfiniBand{}), additional
settings are required to define the IPoIB network with \Confluent{} and specify
desired IP settings for each compute. This can be accomplished as follows for
the {\em ib0} interface:

% begin_ohpc_run
% ohpc_validation_newline
% ohpc_validation_comment Setup IPoIB networking
% ohpc_command if [[ ${enable_ipoib} -eq 1 ]];then
% ohpc_indent 5
\begin{lstlisting}[language=bash,keywords={},upquote=true,basicstyle=\footnotesize\ttfamily]

[sms](*\#*) for ((i=0; i<$num_computes; i++)) ; do
nodeattrib ${c_name[i]} net.ib0.ipv4_address=${c_ipoib[i]}/${ipoib_netmask}
done
\end{lstlisting}
% ohpc_indent 0
% ohpc_command fi
% end_ohpc_run

%\clearpage
With the desired compute nodes and domain identified, the remaining steps in the
provisioning configuration process are to define the provisioning mode and
image for the {\em compute} group and use \Confluent{} commands to complete
configuration for network services like DNS and DHCP. These tasks are
accomplished as follows:

%\clearpage
% begin_ohpc_run
% ohpc_validation_newline

\begin{lstlisting}[language=bash,keywords={},upquote=true,basicstyle=\footnotesize\ttfamily,literate={BOSSHORT}{\baseosshort{}}1 {IMAGE}{\installimage{}}1]
# Associate desired provisioning image for computes

\end{lstlisting}

The next step is adding \OHPC{} components to the {\em compute} nodes that at this
point are running basic OSes. This process will leverage two \Confluent{}-provided
commands: \texttt{nodeshell} to run \texttt{\pkgmgr{}} installer on all the
nodes in parallel and \texttt{nodersync} to distribute configuration files from the
SMS to the {\em compute} nodes.

\noindent To do this, repositories on the {\em compute} nodes need to be configured
properly.

\Confluent{} has automatically setup an OS repository on the SMS and configured the
nodes to use it, but it has also enabled online OS repositories.


\noindent Next, we alse add the OHPC repo to the compute nodes \S\ref{sec:enable_repo}

% begin_ohpc_run
% ohpc_comment_header Setup nodes repositories and Install OHPC components \ref{sec:add_components}
\begin{lstlisting}[language=bash,literate={-}{-}1,keywords={},upquote=true]
# Add OpenHPC repo
[sms](*\#*) (*\chrootinstall*) \
http://repos.openhpc.community/OpenHPC/3/EL_9/x86_64/ohpc-release-3-1.el9.x86_64.rpm
\end{lstlisting}
% end_ohpc_run

The {\em compute} nodes also need access to the EPEL repository, a required
dependency for \OHPC{} packages.

% begin_ohpc_run
% ohpc_comment_header Configure access to EPEL repo
\begin{lstlisting}[language=bash,literate={-}{-}1,keywords={},upquote=true]
# Add epel repo
[sms](*\#*) (*\chrootinstall*) epel-release

\end{lstlisting}
% end_ohpc_run


\noindent Additionally, a workaround is needed for \OHPC{} documentation files,
which are installed into a read-only NFS share /opt/ohpc/pub. Any package
attempting to write to that directory will fail to install. The following
prevents that by directing \texttt{rpm} not to install documentation files on
the {\em compute} nodes:

% begin_ohpc_run
\begin{lstlisting}[language=bash,literate={-}{-}1,keywords={},upquote=true]
[sms](*\#*) nodeshell compute echo -e %_excludedocs 1 \>\> ~/.rpmmacros
\end{lstlisting}
% end_ohpc_run

\noindent Now \OHPC{} and other cluster-related software components can be
installed on the nodes. The first step is to install a base compute package:
% begin_ohpc_run
% ohpc_comment_header Add OpenHPC base components to compute image
\begin{lstlisting}[language=bash,literate={-}{-}1,keywords={},upquote=true]
# Install compute node base meta-package
[sms](*\#*) (*\chrootinstall*) ohpc-base-compute
\end{lstlisting}
% end_ohpc_run

\noindent Next, we can include additional components:

With the provisioning services enabled, the next step is to define
a system image that can subsequently be
used to provision one or more {\em compute} nodes. The following subsections highlight this process.

\subsubsection{Build initial BOS image} \label{sec:assemble_bos}
The following steps illustrate the process to build a minimal, default image for use with \Confluent{}. To begin, you will
first need to have a local copy of the ISO image available for the underlying OS. In this recipe, the relevant ISO image
is \texttt{Rocky-9.4-x86\_64-dvd.iso} (available from the Rocky
\href{https://rockylinux.org/download/}{\color{blue}download} page).
We initialize the image
creation process using the \texttt{osdeploy} command assuming that the necessary ISO image is available locally in
\texttt{\$\{iso\_path\}} as follows:

The \texttt{osdeploy initialize} command is used to prepare a confluent server to deploy deploy operating systems.
For first time setup, run osdeploy initialize interactively to be walked through the various options using:
\texttt{osdeploy initialize -i}

% begin_ohpc_run
% ohpc_comment_header Initialize OS images for use with Confluent \ref{sec:assemble_bos}
\begin{lstlisting}[language=bash,literate={-}{-}1,keywords={},upquote=true,keepspaces,literate={BOSVER}{\baseos{}}1]
[sms](*\#*) osdeploy initialize -${initialize_options}
[sms](*\#*) osdeploy import ${iso_path}

\end{lstlisting}
% end_ohpc_run

\noindent Once completed, OS image should be available for use within \Confluent{}. These can be queried via:

\begin{lstlisting}[language=bash,literate={-}{-}1,keywords={},upquote=true,keepspaces,literate={BOSVER}{\baseos{}}1]
# Query available images
[sms](*\#*) osdeploy list
Distributions:
rocky-8.5-x86_64
rocky-9.4-x86_64
Profiles:
rhel-9.4-x86_64-default
rocky-8.5-x86_64-default
\end{lstlisting}

If needing to copy files from the sms node to the compute nodes during deployment, this can be done by
modifying the syncfiles file that is created when \texttt{osdeploy import} command is run. For an environment
that has no DNS server and needs to have /etc/hosts file synced amongst all the nodes, the following command
should be run.

% begin_ohpc_run
% ohpc_validation_newline
% ohpc_validation_comment Sync the hosts file in cluster
\begin{lstlisting}[language=bash,literate={-}{-}1,keywords={},upquote=true,keepspaces,literate={BOSVER}{\baseos{}}1]
[sms](*\#*) echo "/etc/hosts -> /etc/hosts" >> /var/lib/confluent/public/os/rocky-9.4-x86_64-default/syncfiles

\end{lstlisting}
% end_ohpc_run


%The \texttt{CHROOT} environment variable highlights the path and is used by
%subsequent commands to augment the basic installation.

At this point, all of the packages necessary to use \Confluent{} on the {\em master}
host should be installed. Next, we enable support for local provisioning using
a second private interface (refer to Figure~\ref{fig:physical_arch})

% begin_ohpc_run
% ohpc_comment_header Complete basic Confluent setup for master node \ref{sec:setup_confluent}
%\begin{verbatim}
\begin{lstlisting}[language=bash,literate={-}{-}1,keywords={},upquote=true,keepspaces]
# Enable internal interface for provisioning
[sms](*\#*) ip link set dev ${sms_eth_internal} up
[sms](*\#*) ip address add ${sms_ip}/${internal_netmask} broadcast + dev ${sms_eth_internal}

\end{lstlisting}
%\end{verbatim}
% end_ohpc_run


\noindent \Confluent{} requires a network domain name specification for system-wide name
resolution. This value can be set to match your local DNS schema or given a
unique identifier such as `local`. A default group called everything is
automatically added to every node. It provides a method to indicate global settings.
Attributes may all be specified on the command line, and an example set could be:

% begin_ohpc_run
% ohpc_validation_newline
% ohpc_validation_comment Define local domainname, deployment protocol and dns
\begin{lstlisting}[language=bash,keywords={},upquote=true,basicstyle=\footnotesize\ttfamily,literate={BOSVER}{\baseos{}}1]
