Answer My Own Question
I recently upgraded to Airflow 1.10 which introduced the KubernetesPodOperator however whenever I use it I see the following error in the webserver: No module named 'kubernetes'. Why does this happen and how can I fix it?
This happens because the kubernetes library isn't installed with vanilla airflow. You can fix this by running pip install "apache-airflow[kubernetes]".
For airflow 1.10.4,
pip install 'apache-airflow[cncf.kubernetes]'

I want to run celery on background as a daemon on AWS Elastic Beanstalk with python3.6.
I followed answer of this question :How do you run a worker with AWS Elastic Beanstalk?
But supervisor is not supported for python3.6 . What is solution for python 3.6.
Note : I am using Rabbitmq server and setup celery on my project as a remote server.
Master branch of supervisor supports Python 3. You can use it. It may have some bugs as it is in development.
To install it, run
$ pip install git+https://github.com/Supervisor/supervisor.git
Ensure git installed in your system for the above command to work.
As I mentioned here, you can also use mozilla circus which is an alternative for celery.
After one day of research finally I got the answer of my question :
Just installed git on Eb.
packages:
yum:
git: []
Add supervisor on requirements.txt :

We have a Redmine instance on the centos 7 server with Bitnami. I am getting following error during installation of an another Redmine instance.
Command Used:
[root#localhost htdocs]# bundle install --without development test
Error Message:
An error occurred while installing mysql2 (0.3.21), and Bundler cannot continue.
Make sure that gem install mysql2 -v '0.3.21' succeeds before bundling.
The Bitnami installer includes a ready to use Redmine stack, so I assume you're trying to install additional plugins on the vanilla Redmine install.
I suspect that you forgot to load the proper environment variables to use the Bitnami Stack mysql libraries. Go to your install directory (usually /opt/bitnami/redmine) and execute this source ./use_redmine
And then follow this instructions https://docs.bitnami.com/installer/apps/redmine/#install_plugins
I've downloaded kubernetes binary release 1.4.1 and want to install it on my Centos 7 cluster. The official guide is based on "yum install ...".
Is there any guide/instruction show me how to install and configure k8s using a binary release?
Highly appreciate your help.
I was struggling with the same setup too. After hours of googling I decided to go the kubeadm way.
wget https://github.com/kubernetes/release/archive/master.zip
unzip master.zip
cd release-master/rpm && ./docker-build.sh
This produced three rpm packages of v1.4.3. After installing packages, simply run kubeadm init and that is all.
In addition, there is some nice documentation for CoreOS , I tried to follow this first, but then I got compatibility issues in configuration between CentOS and CoreOS. Hope this helps.
