Red Hat CodeReady Containers brings a minimal OpenShift 4.1 or newer cluster to your local computer (see https://code-ready.github.io/crc/)

Ansible Agnostic Deployer aka AgnosticD, is a fully automated 2 Phase deployer for building and deploying everything from basic infrastructure to fully configured running application environments running on either public Cloud Providers or OpenShift clusters.

AgnosticD is not an OpenShift Deployer, though it can and does that, it is however also a deployer that just happens to be used to deploy a lot of OpenShift and OpenShift workloads, amongst other things. See https://github.com/redhat-cop/agnosticd

Open Data Hub is a machine-learning-as-a-service platform built on Red Hat's Kubernetes-based OpenShift® Container Platform, Ceph Object Storage, and Kafka/Strimzi integrating a collection of open source projects. See https://opendatahub.io/

The instructions below cover

installing Red Hat CodeReady Containers on a RHEL 8.1 or 8.2 physical server

(You can also use Fedora 30, please https://github.com/marcredhat/crcdemos/blob/master/fedora/README.adoc)

using Ansible Agnostic Deployer to deploy OpenDataHub on OpenShift 4.1 or 4.2
configuring SSH tunneling / port forwarding to access the OpenShift console, OpenDataHub etc from your laptop.

[marc@dell-r730-019 ~]$ cat /etc/redhat-release

Red Hat Enterprise Linux release 8.1 Beta (Ootpa)

== Install packages

su -c 'dnf -y install git wget tar qemu-kvm libvirt NetworkManager jq'

sudo systemctl start libvirtd

sudo systemctl enable libvirtd

== Install Python

See https://developers.redhat.com/blog/2019/05/07/what-no-python-in-red-hat-enterprise-linux-8/

yum install @python36

yum install @python27

When you install either (or both) you can easily make /usr/bin/python point to the right place using alternatives --config python

[root@dell-r730-019 ~]# alternatives --config python

There are 3 programs which provide 'python'.

Selection Command *+ 1 /usr/libexec/no-python 2 /usr/bin/python2 3 /usr/bin/python3

Choose 3

[marc@dell-r730-019 ansible]$ python -V

Python 3.6.8

== Add user

adduser marc

passwd marc

usermod -aG wheel marc

== Install Go

cd /home/marc

wget https://dl.google.com/go/go1.12.9.linux-amd64.tar.gz

tar -xzf go1.12.9.linux-amd64.tar.gz

Add to .bashrc:

export GOROOT=/home/marc/go

export GOPATH=/home/marc/work

export PATH=$GOPATH/bin:$GOROOT/bin:$PATH

source .bashrc

== Install CodeReady Containers

wget https://mirror.openshift.com/pub/openshift-v4/clients/crc/latest/crc-linux-amd64.tar.xz

tar -xvf crc-linux-amd64.tar.xz

cd crc-linux-1.0.0

Set the memory available to CRC according to what you have on your physical server

I’m on a physical server with around 100G of memory so I allocate 80G to CRC as follows:

./crc config set memory 81920

./crc config set cpus <cpus>

You’ll need your pull secret from https://cloud.redhat.com/openshift/install/metal/user-provisioned ./crc setup ./crc start

Increase disk size available to CodeReady Containers (see https://github.com/code-ready/crc/issues/127)

sudo dnf -y install libguestfs libguestfs-tools CRC_MACHINE_IMAGE=${HOME}/.crc/machines/crc/crc #example : CRC_MACHINE_IMAGE=/home/demouser/.crc/machines/crc/crc ./crc stop #adding 500G sudo qemu-img resize ${CRC_MACHINE_IMAGE} +500G sudo cp ${CRC_MACHINE_IMAGE} ${CRC_MACHINE_IMAGE}.ORIGINAL sudo virt-resize --expand /dev/sda3 ${CRC_MACHINE_IMAGE}.ORIGINAL ${CRC_MACHINE_IMAGE} sudo rm ${CRC_MACHINE_IMAGE}.ORIGINAL ./crc setup ./crc start ./crc status

Expected result

crc status CRC VM: Running OpenShift: Stopped Disk Usage: 33.88GB of 569.1GB (Inside the CRC VM) Cache Usage: 15.95GB Cache Directory: /home/demouser/.crc/cache
