Deploying Elasticsearch on Openshift

Notes to self. Or if anyone can help with this.

1. Helm charts ⇒ Openshift

Use Elastic’s helm charts as basis (couldn’t find anything more suitable - e.g. operator or Openshift Templates ):

I couldn’t use Helm itself due to permissions issues related to: helm/helm#1918

Fetch Rubygems.org dependencies

When you only have / want to use a Gemfile.lock to retrieve the Ruby dependencies for a project, you can use this little ruby script.

There might be several reasons why you may want to do this:

• You may not have the original Gemfile available
• You may not want to interpret the ruby code in Gemfiles to avoid arbitrary code execution risks.

Usage

gsaslis

#!/usr/bin/env bash

SAVEIFS=$IFS    # save old IFS value
IFS=$'\n'       # make newlines the only separator
echo "Powering off all running VMs"
for vm in $(VBoxManage list runningvms | awk '{print substr($2, 2, length($2) - 2)}') # you might want to limit your search by `| grep 'some vm name here' ` *before* the pipe to awk 
do
echo "Powering off VM ${vm}"
VBoxManage controlvm ${vm} poweroff
echo "VM ${vm} powered off"
