vsphere openshift4 automation

VERY BASIC playbook using openshift-install and govc to create an openshift cluster in vsphere.

• Downloads Installer
• Generates Manifests
• Generates Ignition Configs
• Places the ignition configs in a local apache directory (for the VMs to fetch later)
• Creates VMs (prereq: template must exist in the cluster)
• Modifies VMs to add "append" ignition configs to them - to tell the VMs to get the config from the http server

Instructions followed as per: https://blog.openshift.com/openshift-4-2-vsphere-install-quickstart/

How to run

I run this playbook from the same host that has had https://github.com/christianh814/ocp4-upi-helpernode run on it.

Ensure you have govc installed.

curl -L https://github.com/vmware/govmomi/releases/download/v0.21.0/govc_linux_amd64.gz | gunzip > /usr/local/bin/govc
chmod +x /usr/local/bin/govc

Ensure /usr/local/bin is on your $PATH:

echo "PATH=\$PATH:/usr/local/bin" >> ~/.bashrc
source ~/.bashrc

And ensure you have the appropriate GOVC environment variables populated:

export [email protected]
export GOVC_PASSWORD=password
export GOVC_URL=my.vcenter.lan
export GOVC_INSECURE=true

Ensure you have the appropriate vars file populated as per the playbook.

Run the playbook with:

ansible-playbook create-vsphere-machines.yml -vv

Please note that everything happens in a temp directory:

TASK [create-ocp4-manifests : Create temporary directory] **********************************************************************************************************
task path: /some/path/vsphere-openshift4-automation/roles/create-ocp4-manifests/tasks/setup.yml:2
changed: [localhost] => {"changed": true, "gid": 1000, "group": "hello", "mode": "0700", "owner": "user", "path": "/tmp/ansible.s4i72i7g", "secontext": "unconfined_u:object_r:user_tmp_t:s0", "size": 40, "state": "directory", "uid": 1000}

In this case everything will be in /tmp/ansible.s4i72i7g
