Getting started

Requires Ansible to be installed.

git clone https://gitlab.com/rgdacosta/classroom_env.git

cd classroom_env

ansible-playbook playbook.yml

Using

Check out these files for more information:

~/.bashrc

~/.vimrc

~/.tmux.conf

Resolution and gnome terminal profiles are set.

For those who prefer a bigger font, set biggerfont as the default profile in the terminal preferences. regularfont is implemented as the default.

OpenShift classes

The RHT_OCP4_ variables can be difficult to type at times, often resulting in typos and hindered success.

Newer, simpler variables are available should /usr/local/etc/ocp4.config exist.

M=$RHT_OCP4_MASTER_API
WC=$RHT_OCP4_WILDCARD_DOMAIN
NS=$RHT_OCP4_NEXUS_SERVER
U=$RHT_OCP4_DEV_USER
P=$RHT_OCP4_DEV_PASSWORD
G=$RHT_OCP4_GITHUB_USER
Q=$RHT_OCP4_QUAY_USER

This means that you are able to use $NS when referring to the Nexus Server

If you forget what these variables are then use the function my_ocp

Logging into clusters:

lcl - local cluster login as admin (OpenShift courses <4.12)
mcl - managed cluster login as admin (DO480)
al - admin login (OpenShift courses >=4.12
dl - developer login
