vagrant-openshift

This is vagrant configuration for running VirtualBox vms with 1 master and 2 nodes.

Usage

1. Install vagrant: brew cask install vagrant
2. Install ansible: brew install ansible
3. Run vagrant: vagrant up
4. Configure each vagrant machine /etc/hosts, add these lines:

10.17.4.202 node2
10.17.4.201 node1
10.17.4.2 master1

5. Download repository with openshift-ansible installer: git clone git@github.com:openshift/openshift-ansible.git
6. Select openshift version for changing branch of openshift-ansible repository, e.g: git checkout release-3.7
7. Edit inventory/hosts file in openshift-ansible, example checked in repository:

[OSEv3:children]
masters
nodes
etcd

[OSEv3:vars]
# if your target hosts are Fedora uncomment this
#ansible_python_interpreter=/usr/bin/python3
openshift_deployment_type=origin
openshift_release=3.7
osm_cluster_network_cidr=10.128.0.0/14
openshift_portal_net=172.30.0.0/16
osm_host_subnet_length=9
# localhost likely doesn't meet the minimum requirements
openshift_disable_check=disk_availability,memory_availability,docker_storage

[masters]
master1 ansible_ssh_host=10.17.4.2 openshift_ip="10.17.4.2" openshift_hostname="master1"

[etcd]
master1 ansible_ssh_host=10.17.4.2 openshift_ip="10.17.4.2" openshift_hostname="master1"

[nodes]
master1 ansible_ssh_host=10.17.4.2 openshift_ip="10.17.4.2" openshift_hostname="master1"
node1 ansible_ssh_host=10.17.4.201 openshift_ip="10.17.4.201" openshift_node_labels="{'region': 'infra', 'zone': 'default'}"
node2 ansible_ssh_host=10.17.4.202 openshift_ip="10.17.4.202" openshift_node_labels="{'region': 'infra', 'zone': 'default'}"

8. Install cluster: ansible-playbook -i inventory/hosts playbooks/byo/config.yml
9. Install oc tool from: https://www.openshift.org/download.html
10. Modify your systems /etc/hosts to add ip to master1
11. Login to master1: oc login https://master1:8443 -u admin, type any characters as password.

Ansible playbooks

Create nfs for persistent storage

You can run setup-nfs-server.yml playbook to create nfs share for persistent storage. This playbook creates nfs shares from nfs_dirs variable.

Configure external registry-console

1. oc expose service registry-console --hostname=registry-console.10.17.4.202.xip.io --name=docker-registry-xip <= this command expose registry using xip.io to be availible outside the cluster
2. Change TLS to Passthrough
3. By default oauthclient uses internal registry-console url to redirect after authorization. To change this you need to export registry-console oauthclient and change url.

oc export oauthclients cockpit-oauth-client -o yaml > oauthclient.yaml

1. Next change redirectURIs to point to https://registry-console.10.17.4.202.xip.io
2. Apply changes: oc apply -f oauthclient.yaml

Use docker registry from host

1. expose registry using xip.io domain: oc expose service docker-registry --hostname=docker-registry.10.17.4.202.xip.io --name=docker-registry-xip
2. Change TLS to Passthrough
3. login to docker registry docker login -p <pass_from_console_ui> -u unused docker-registry.10.17.4.202.xip.io
4. Push to registry: docker push docker-registry.10.17.4.202.xip.io/project/image:tag

• create hosts file automatically
