Rancher is a comprehensive container management platform engineered to streamline the complexities of deploying and administering containerized applications across diverse infrastructure landscapes. Equipped with support for leading container orchestration engines such as Kubernetes, Docker Swarm, and Apache Mesos, Rancher offers a cohesive interface for provisioning, scaling, and updating containerized workloads. Its versatility extends across on-premises servers, cloud environments, and hybrid setups, ensuring a unified management experience regardless of the underlying infrastructure. By providing robust tools and features, Rancher empowers organizations to efficiently manage containerized applications, facilitating the seamless adoption of containerization and microservices architectures.
It will take a few minutes for your VM to be deployed. When the deployment is finished, move on to the next section.
Connect to virtual machine
Create an SSH connection with the VM.
bashCopy
ssh azureuser@10.111.12.123
Usage/Deployment Instructions
Step 1: Access the Rancher in Azure Marketplace and click on Get it now button.
Click on Continue and then click on Create.
Step 2: Now to create a virtual machine, enter or select appropriate values for zone, machine type, resource group and so on as per your choice.
Click on Review + create.
Step 3: The below window confirms that VM was deployed.
Step 4: Open port 8080 in security group by going to resource group –
Step 5: Open putty and connect with your machine. Add IP address of the running virtual machine.
Step 6: Login with user name and password that you provided during machine creation.
Once your Deployment is successful , follow the following Steps;
Step 1: Please open the following Security Ports in the instance:
To access the Rancher user interface, open a web browser and type the server IP number and port in the URL bar following the syntax:
Once you have accessed the platform, Rancher instructs you to set up the Admin user (one that has full control over Rancher).
1. Open the ADMIN drop-down menu and click Access Control.
2. Click the LOCAL button in the menu to move to the Local Authentication window.
Provide the required information to set up an Admin user and click Enable Local Auth to confirm.
When creating a custom Kubernetes cluster on Rancher, you need to provision a Linux host (an on-premise virtual machine, a cloud-host VM or a bare metal server). Then, you can create your custom Kubernetes cluster.
1. Open the INFRASTRUCTURE drop-down menu and select HOSTS.
2.The instructions inform you that the host needs to have a supported version of Docker and allowed traffic to and from hosts on ports 500 and 4500. Start up the machine making sure it has all the specified prerequisites.
3. Rancher gives you an option to add a label to the host.
4. Provide the IP address that should be registered for this host.
5. Doing so generated a unique command which should be run on the specified host.
6. Copy and paste the command in the terminal window.
7. Click Close and wait for the new host to appear on the Host screen.
With the Linux host assigned, move on to creating a custom cluster.
1. Navigate to the Clusters page and click Add Cluster.
2. Select Existing Nodes.
3. Type a Cluster Name, and click Next.
4. Under Node Options, choose what roles you want the nodes to have (etcd, Control Plane, and/or Worker).
5. In Cluster Options, chose the Kubernetes Version and the Network Provider:
6. Choose the cloud provider. If you do not have one, select None.
7. Copy and paste the generated command on each worker node machine and wait for the cluster to start up.
Until now, small developers did not have the capital to acquire massive compute resources and ensure they had the capacity they needed to handle unexpected spikes in load. Amazon EC2 enables any developer to leverage Amazon’s own benefits of massive scale with no up-front investment or performance compromises. Developers are now free to innovate knowing that no matter how successful their businesses become, it will be inexpensive and simple to ensure they have the compute capacity they need to meet their business requirements.
The “Elastic” nature of the service allows developers to instantly scale to meet spikes in traffic or demand. When computing requirements unexpectedly change (up or down), Amazon EC2 can instantly respond, meaning that developers have the ability to control how many resources are in use at any given point in time. In contrast, traditional hosting services generally provide a fixed number of resources for a fixed amount of time, meaning that users have a limited ability to easily respond when their usage is rapidly changing, unpredictable, or is known to experience large peaks at various intervals.
Traditional hosting services generally provide a pre-configured resource for a fixed amount of time and at a predetermined cost. Amazon EC2 differs fundamentally in the flexibility, control and significant cost savings it offers developers, allowing them to treat Amazon EC2 as their own personal data center with the benefit of Amazon.com’s robust infrastructure.

In contrast, traditional hosting services generally provide a fixed number of resources for a fixed amount of time, meaning that users have a limited ability to easily respond when their usage is rapidly changing, unpredictable, or is known to experience large peaks at various intervals.
Secondly, many hosting services don’t provide full control over the compute resources being provided. Using Amazon EC2, developers can choose not only to initiate or shut down instances at any time, they can completely customize the configuration of their instances to suit their needs – and change it at any time. Most hosting services cater more towards groups of users with similar system requirements, and so offer limited ability to change these.
Finally, with Amazon EC2 developers enjoy the benefit of paying only for their actual resource consumption – and at very low rates. Most hosting services require users to pay a fixed, up-front fee irrespective of their actual computing power used, and so users risk overbuying resources to compensate for the inability to quickly scale up resources within a short time frame.
You have complete control over the visibility of your systems. The Amazon EC2 security systems allow you to place your running instances into arbitrary groups of your choice. Using the web services interface, you can then specify which groups may communicate with which other groups, and also which IP subnets on the Internet may talk to which groups. This allows you to control access to your instances in our highly dynamic environment. Of course, you should also secure your instance as you would any other server.
