"Learn OpenShift" is a step by step hands-on guide which gives you some practical OpenShift-related examples
The repository gives a number of folders which proides all files required for a Lab. The following labs are included:
| Lab | Description |
|---|---|
| Lab 0 | Creating lab environment (please see below) |
| Lab 1 | Overview of the lab environment |
| Lab 2 | Managing user projects |
| Lab 3 | Managing Pods |
| Lab 4 | Managing Services |
| Lab 5 | Managing Routes |
| Lab 6 | Application deployment with oc new-app |
| Lab 7 | Injecting configuration data using config maps and secrets |
| Lab 8 | Using OpenShift templates |
| Lab 9 | Using persistent storage |
| Lab 10 | Building application from Dockerfile |
| Lab 11 | Building applications from source code |
CentOS 7 minimal is required to deploy this lab environment.
The repository includes a Vagrantfile which deploys a VM with the following configuration:
| Option | Value |
|---|---|
| RAM | 6000M |
| vCPU | 2 |
| IP | 172.24.0.11 |
| Hostname | openshift.example.com |
| Box | centos/7 |
The VM is customized as follows:
- docker and git packages are installed
- docker Linux group is created
- the vagrant user is a member of the docker Linux group (this allows to use Docker client under unprivileged user)
- OpenShift 3.11 repository is configured
- OpenShift client utility is installed
- OpenShift cluster is deployed using "oc cluster up"
- OpenShift public url is set to openshift.172.24.0.11.nip.io
The host machine can be configured on the following OS:
- MacOS
- Windows
- Fedora Linux
- CentOS 7
The following software is required:
- VirtualBox(Windows and MacOS)
- libvirt(Linux only)
- Vagrant
- git
- vim
The lab environment can be provisioned using Vagrant as follows:
git clone https://github.com/li9com/learn-openshift.git
cd learn-openshift
vagrant up
Once VM is provisioned, you may connect to it using SSH as follows:
vagrant ssh
Note! You will be connected as the "vagrant" user which is allowed to use sudo to run commands under the root account, for example:
sudo yum install -y epel-release
You may access OpenShift console using the following URL:
https://openshift.172.24.0.11.nip.io:8443/console/
