Provide an immersive experience for students through practical application of DevOps culture using modern software development practices.
Allow students to experience the cultural shift they need to make in order to begin a successful DevOps journey.
An OpenShift Cluster is required to complete the lab exercises. Students will receive by email (and by the instructors on site) the following information regarding the OpenShift cluster:
- <**CLUSTER_URL**> -- Openshift Webconsole/API Server URL
- <**APPS_URL**> -- Wildcard subdomain for the exposed applications deployed in the Cluster
The following are the minimal hardware requirements for running the lab exercises in this course
* 64-bit Intel Core i5/i7 CPU or equivalent with virtualization extensions enabled

, so the screenshots will match its layout and color schemes) | - | - |
NOTE
> You will need administrator or super user level access on your system to install the prerequisite software for all the three operating systems.
Locked down systems with restricted accounts are not supported.
> You can use any text editor to edit lab files. Using an editor that provides syntax highlighting and automatic indentation is helpful. We recommend Atom or Visual Studio Code for this course.
Download the Node.js 8.x LTS Linux 64-bit binary archive file from https://nodejs.org/dist/latest-v8.x/. The binary will be named as node-v8.x.y-linux-x64.tar.gz, where 'x' and 'y' indicates the major and minor version of the latest Node.js 8 LTS release.bash tar -xvzf node-v8.x.y-linux-x64.tar.gz -C /usr/local/
Replace 'x' and 'y' with the version you downloaded in the above step.
Edit your .bashrc file and add the node binary to your PATH environment variablebash echo 'export PATH=/usr/local/node-v8.x.y/bin:$PATH' >> $HOME/.bashrc
Install OpenJDK version 1.8bash dnf install java-1.8.0-openjdk-devel
Install Google Chrome version 70 or higher by downloading and running the the 64-bit RPM installer from https://google.com/chromebash dnf install google-chrome-stable_current_x86_64.rpm
bash dnf install git ansible docker systemctl enable docker systemctl start docker
bash wget https://github.com/openshift/origin/releases/download/v3.11.0/openshift-origin-client-tools-v3.11.0-0cbc58b-linux-64bit.tar.gz tar -xvzf openshift-origin-client-tools-v3.11.0-0cbc58b-linux-64bit.tar.gz cp openshift-origin-client-tools-v3.11.0-0cbc58b-linux-64bit/oc /usr/local/bin/ chmod +x /usr/local/bin/oc
bash dnf install <rpm_name>
Install HomeBrew for macOS by following the installation instructions at https://brew.sh/
Install Node.js version 8.x LTS using the brew command, and follow the instructions to add the node binary to the PATH environment variable.bash brew install node@8
Install Google Chrome version 70 or higher by downloading it from https://google.com/chrome
Install Docker for Mac by following the instructions from https://store.docker.com/editions/community/docker-ce-desktop-mac
Install Git using brewbash brew install git
You need Ansible version 2.5 or greater to run the exercise playbooks. If you have not installed Ansible, or have an older version, install or upgrade it using brewbash brew install ansible
Download and uncompress the OpenShift 3.11 client binary archive. Copy the oc binary to /usr/local/bin folder on your systembash curl -L -O https://github.com/openshift/origin/releases/download/v3.11.0/openshift-origin-client-tools-v3.11.0-0cbc58b-mac.zip unzip openshift-origin-client-tools-v3.11.0-0cbc58b-mac.zip cp oc /usr/local/bin/ chmod +x /usr/local/bin/oc
You will be adding several directories to the PATH environment variable. Follow the instructions at https://www.architectryan.com/2018/03/17/add-to-the-path-on-windows-10/ to edit the PATH environment variable on Windows 10.
Extract the zip file archive under a suitable folder in the *C:* drive, for example C:\nodejs. Make sure that your directory name does not have any spaces in it.
Add the directory where you uncompressed the zip file to the PATH environment variable, so that the node.exe and npm.cmd executable files are available in the system path.
Ensure that you install the JDK into a directory which has no spaces in its name, for example C:\Java. Add a new environment variable called JAVA_HOME which points to the top level directory where you installed the JDK.
Add the JAVA_HOME\bin directory to the PATH environment variable, so that the java.exe and javac.exe executable files are available in the system path.
Install Google Chrome version 70 or higher by downloading it from https://google.com/chrome
Install Docker for Windows by following the instructions from https://hub.docker.com/editions/community/docker-ce-desktop-windows. Before downloading, you will be asked to create an account. Register and download Docker for Windows.
Ensure that you install Docker into a directory which has no spaces in its name, for example C:\Docker. You will be prompted to enable Hyper-V during installation.
Windows will restart a couple of times after enabling Hyper-V and continue with the Docker installation. Follow the instructions provided in the link above to test and verify your Docker installation.
Follow the instructions at https://www.atlassian.com/git/tutorials/install-git#windows to install and verify your Git installation. Ensure that you install Git into a directory which has no spaces in its name, for example C:\Git.
NOTE
Ensure that the Git Bash component is selected during installation. You will need this to run bash shell scripts during the execution of lab exercises.
Download and install Atom text editor from https://github.com/atom/atom/releases/download/v1.33.0/AtomSetup-x64.exe, or Visual Studio Code from https://code.visualstudio.com/docs/?dv=win64
You will use a custom container image for running OpenShift client commands, and Ansible playbooks. You will map a directory on your local Windows system containing Ansible playbooks to a directory inside the container, and run the Ansible playbooks from within the container.
Execute the following commands in the Windows Command Prompt to run Ansible playbooks on Windows systems:
bash docker pull quay.io/redhat/do500-toolbox
bash mkdir C:\do500-workspace
Launch the container and run a quick test:bash docker run -it -v C:/do500-workspace:/home/tool-box/workarea:Z quay.io/redhat/do500-toolbox /bin/bash
NOTE
When you launch the container for the very first time, you will be prompted by Docker, as well as the Windows security subsystem to allow read and write access to the C:\do500-workspace directory. Allow read and write access to this directory by entering your Windows username and password when prompted.
bash bash-4.4$ oc login -u <username> -p <password> <CLUSTER_URL> bash-4.4$ oc version bash-4.4$ ansible --version bash-4.4$ exit
Your instructor will provide the username and password information for the OpenShift cluster when you are ready to run the lab exercises.
The following plug-ins are useful for providing syntax highlighting for various lab files:
- YAML Syntax Highlighter
- JavaScript Syntax Highlighter
- Vue.js
- ESlint
- Jenkinsfile
