git-hyagi/ocp4-aws-installer

A program to make the OCP4 install on AWS even easier

ABOUT

The process of install the OpenShift 4 is a lot easier compared to the 3.x version (which was based on running Ansible playbooks).
To make it even easier, the ocp4-aws-installer just help with some steps:

• gather the pull-secret
• download and install the openshift-install program
• download and install the oc (openshift client)

PRE-REQUISITES

• A ssh key that can be used to SSH into the master nodes as the user core. When you deploy the cluster, the key is added to the core user's ~/.ssh/authorized_keys list. Example of command to create a new ssh key:

$ ssh-keygen -t rsa -b 4096 -N '' -f ~/.ssh/ocp4

• Follow the steps from documentation to configure the AWS account:
  • Configuring Route53
  • AWS account limits
  • Required AWS permissions
  • Creating an IAM user
  • (optional) Configure the ~/.aws/credentials:

[default]
aws_access_key_id = <AWSKEY>
aws_secret_access_key = <AWSSECRETKEY>
region = sa-east-1

• A Red Hat account

INSTALLING THE ocp4-aws-installer

There is no need to install the ocp4-aws-installer. Just clone or download this repo:

$ git clone https://github.com/git-hyagi/ocp4-aws-installer.git

RUNNING

After completing all the pre-requisites and downloading the program, run:

$ go run ocp4-aws-installer.go

During the program execution it will be asked to pass an username and password. They'll be used to get the pull-secret from https://cloud.redhat.com/openshift/install and create the /tmp/pull-secret.txt file.
If the ocp4-aws-installer finished successfuly, begin the installation with:

$ openshift-install create cluster --dir <install dir>
