Good articles on Celery groups, and chords

 The first article gives deep and profound explanation how groups and chords can be handled. What is the most valuable, from my point of view, are database models implemented in Django-ORM to embody tasks persistence. I recommend it to read.


The second article is more of introductory level. Good to read, but I would not expect to much.

Install Kubeflow locally

For local installation of Kubeflow you can use Vagrant box, Minikube or install it using Multipass. Here I will describe the multipass installation. The best link for the installation process is here . This installation uses Microk8s orchestrator and has some caveats. First of all you have to create volumes manually, other way you services won't work correctly. Before all I would suggest to install version 1.13 of microk8s, because 1.14 is not compatible now with kubflow. sudo snap install microk8s --channel=1.13 For this purpose please edit kubernetes-tools/setup-microk8s.sh line 10: CHANNEL=${CHANNEL:-1.13/stable} 1.14 where changed on 1.13.

RabbitMQ and OpenShift

RedHat created very good launcher for a RabbitMQ cluster in OpenShift ( can be found here ). The problem I was stacked a little bit was creation of the cluster in an already created project. I found out that it is easy to do, just change slightly a all.yml file. --- openshift_cluster_content: # No need to create a new project #- object: projectrequest # content: # - name: rabbitmq-spaces # file: "{{ inventory_dir }}/../files/projects/projects.yml" # file_action: create - object: imagestream content: - name: rhel7 file: "{{ inventory_dir }}/../files/imagestreams/images.yml" namespace: scouting # Also important to fix deployment config template, which is located in the files/deployments/template.yml . The deployment will hook wrong image, so cluster won't build without the fix. Problem is in the naming of the image used to build rabbits. image: "${APPLICATION_NAME}:${RABBITMQ_VERSION}" Change to: image: ...
