You can up and run MongoDB Docker container in your local machine and later connect from mysql CLI to query your collections.
Run the following command in your terminal to up and run a MongoDB NoSQL Docker container.
docker run -p 27017:27017 --name mongoDbTest -d mongo:latestFollow the following link for more details

You can up and run MySQL Docker container in your local machine and later connect from mysql CLI to query your database.
Run the following command in your terminal to up and run a MySQL Database Docker container.
docker run -p 3306:3306 --name some-mysql -e MYSQL_ROOT_PASSWORD=my-secret-pw -d mysql:latestFollow the following link for more details

There are more practice in this video 🙂
Actually there is already a Kubernetes multi node cluster post (https://kenanhancer.com/2018/09/26/kubernetes-multi-node-cluster-with-vagrant/) in this blog. But, this one is different. That post was showing 3 empty virtual server up and run later install tools step by step so it was taking too much time. If you run this Vagrantfile, it will create one master node and 2 worker nodes in Virtualbox. This Vagrantfile is also more configurable. If you need more servers, just append new item in “servers” array in Vagrantfile.
This is the expected result 🙂 As I mentioned at the beginning of the post, one master node and two worker nodes are created in Virtualbox.
The following Vagrantfile code(syntax is Ruby) is creating single node Kubernetes cluster with Minikube.
Copy above code and follow the following screenshots. Run the following commands in Terminal.
mkdir MinikubeVagrant
cd MinikubeVagrant
nano Vagrantfile
Paste the Vagrantfile content like below.
save Vagrantfile and run the following command to start virtual machine.
vagrant up
After Vagrant is up, it means that Minikube is ready to use. So, connect with SSH to Vagrant machine and run the following code to start Kubernetes Dashboard Proxy.
kubectl proxy --address 0.0.0.0 --port=8001 --accept-hosts '.*'
Click one of the following link to connect the Dashboard. Ta taaa 🙂

Rest of the details are already mentioned in this blog link Kubernetes multi node cluster with Vagrant (included Kubernetes Dashboards, Grafana, Prometheus)
read the Kubernetes Dashboard Access Control paragraph.
It is a very simple example to show how to handle long-running requests in Node.js with RabbitMQ.
You need to have a RabbitMQ docker in development machine.
Install RabbitMQ with Docker
if you have installed Vagrant CLI, just run the following command to create docker installed virtual box.
The following command will download a Vagrantfile file from Vagrant company in the current directory.
vagrant init kenanhancer/DockerMachine
This command will start the virtual machine.
vagrant up
If you want to check status of virtual machine, run the following command.
vagrant status
If you want to see ports of virtual machine, run the following command.
vagrant port
to connect created virtual machine, run the following command in the Vagrantfile directory.
vagrant ssh
if you want to see details of Vagrantfile, check it as below.
vagrant package --output dockermachine.box --vagrantfile Vagrantfile
The following Vagrantfile code(syntax is Ruby) is creating one master node and two worker nodes for Kubernetes.
Go to Vagrantfile directory in Terminal and run the following code to create virtual machines.
As you can see in the below picture, three virtual machines are obtained and running.
But, Kubernetes cluester is still not ready. We created just an environment to install the cluster.

Before you run the following C# code, run the below docker code to have a RabbitMQ applicaton locally.
docker run -d –hostname my-rabbit –name some-rabbit -p 8080:15672 -p 5672:5672 rabbitmq:3-management
After run Docker RabbitMQ container, you can reach from http://localhost:8080/ as shown in following picture.
