openshift Getting started with openshift

Remarks

Getting started with an all-in-one container

To install openshift follow installation steps on https://install.openshift.com

Getting started with Minishift

This is similar to Docker-machine or minikube which are used to learn Docker and Kubernetes. It will run a virtual machine containing everything you need to test openshift-origin.

Here is the documentation from openshift-origin and how to install it on any OS here

I'll write doc for Debian-like OS with virtualbox driver since I did it on my laptop but it's kind of a copy/paste from openshift website

Install Virtualbox

# apt-get install linux-headers-$(uname -r|sed 's,[^-]*-[^-]*-,,') virtualbox
 

Enable and start virtualbox

# systemctl enable virtualbox && \
  systemctl start virtualbox
 

Running systemctl status virtualbox should show you an enabled & active service.

Download minishift & install binary

You can find all minishift releases here in case this one doesn't exist anymore when you try the wget

# mkdir $HOME/minishift && \
  wget -O $HOME/minishift/minishift.tar.gz https://github.com/minishift/minishift/releases/download/v1.0.0/minishift-1.0.0-linux-amd64.tgz && \ 
  tar -xf $HOME/minishift/minishift.tar.gz -C $HOME/minishift
 

Add minishift command to $PATH

# echo "export PATH=\$PATH:$HOME/minishift" >> $HOME/.bashrc && \
  source $HOME/.bashrc
 

Run minishift

minishift --help show all available options

# minishift start --vm-driver=virtualbox
 

Now you should have an openshift up and running

Export openshift client command to $PATH

This command should be installed when you run minishift start if it is not present on the system. Add it to $PATH for more comfort:

# echo "export PATH=\$PATH:$(find $HOME/.minishift -name oc -type f)" >> $HOME/.bashrc && \
  source $HOME/.bashrc
 

Login to minishift

Note: You'll have to accept unsecured ssl certificates

To connect with bash client :

# oc login -u system:admin https://$(minishift ip):8443
 

To connect with your default browser (login with developer:developer):

# minishift console
 

Finally your Openshift-origin-standalone for test/dev purposes is ready and accessible.

Some more things you maybe need to know

• When you are done and want to recover some RAM run minishift stop

• If you want to destroy the all VM containing openshift, run minishift delete

• To see your Openshift master logs, run minishift logs

• To run a shell into the VM containing Openshift, run minishift ssh

• If you are new to openshift and want to try a deployment, check the following doc
