Create a Redis Cluster with docker-machine

Requirements

• docker
• docker-machine
• redis-trib.rb

We use a home made redis-3.0 docker image (https://registry.hub.docker.com/u/bobuss/redis-cluster/), with the cluster mode enabled, and the classical ports exposed (6379 for redis and 16379 for the cluster).

Ideas

I have collected and moderated these ideas from various public sources and put into one place so that problem solvers and solution developers may find inspirations. Because I wish to update it regularly, I have setup as a single page wiki. You may try these ideas on hackathons/competitions/research; some are quite intense problems and some are not. Many of the problems were prepared keeping Dhaka/Bangladesh in mind, but of course can be applied to just about any underdeveloped/developing and sometimes developed countries.

First Method

Deleting the .git folder may cause problems in our git repository. If we want to delete all of our commits history, but keep the code in its current state, try this:

# Check out to a temporary branch:
git checkout --orphan TEMP_BRANCH

# Add all the files:
git add -A

Set secrets as env variables in docker

This script will read your secret file and set each line as an env variable in your container.

How to use it

I' assuming that you already has a entrypoint file in your Dockerfile. So now, you need to copy and paste the contents of set_env_secrets.sh to your entrypoint(you don't need the first line).

Now, you need to create a secret, the name could be whatever you like. I'm using the name of my application as a pattern for my secrets name. For this example, my secret name will be super-project and the content will be.
