Create a Kubernetes cluster
1. Open the Kubernetes tab and click Create Cluster.
2.Select a region — the location of the data center where your cluster will be deployed.
3. Select your Kubernetes cluster version.
4. Under Pools, configure a pool — a set of cluster nodes with the same specifications.
Enter the pool name, set the minimum nodes and maximum nodes for autoscaling.
For Type, select the type of a worker node: a virtual instance or a bare metal server.
For virtual instances, you should select its flavor, disk size in GiB and the disk type.
Standard. These are machines on which the amount of memory in GB is 2–4 times higher than that of vCPUs.
vCPU. These are machines on which the amount of vCPUs equals the amount of memory in GB.
Memory. These are machines on which the amount of memory in GB is much higher (up to 8 times) than that of vCPUs.
High Frequency. These are machines with a high CPU clock speed (3.7 GHz in the basic configuration).
SGX. These are machines that support Intel SGX technology.
High IOPS SSD. This is a high-performance SSD block storage designed for latency-sensitive transactional workloads (60 IOPS per 1 GiB; 2.5 MB/s per 1 GiB). The IOPS performance limit is 9,000. The bandwidth limit is 500 MB/s.
Standard. This is a network SSD disk, which provides stable and high random I/O performance, as well as high data reliability (6 IOPS per 1 GiB; 0.4 MB/s per 1 GiB). The IOPS performance limit is 4,500. The bandwidth limit is 300 MB/s.
Cold. This is a network HDD disk, suitable for less frequently accessed workloads. The maximum number of IOPS is 1,000. The bandwidth limit is 100 MB/s. Please note that this option is unavailable in Manassas.
Ultra. This is the network block storage option, recommended for non-critical data and workloads that are accessed less frequently. The maximum number of IOPS is 1,000. The bandwidth limit is 100 MB/s.
SSD Low-Latency. This is an SSD block storage, designed for applications that require low-latency storage and real-time data processing. It can achieve IOPS performance of up to 5000, with an average latency of 300 µs.
For bare metal servers, you also should select a flavor:
High-frequency. These servers are single-socket servers equipped with 2288G/2388 CPUs, suitable for hosting applications that require high processor frequency.
Infrastructure. These servers are multi-core, multi-socket configurations designed for hosting applications that demand a high number of cores and are optimized for multithreading.
Make sure the Autohealing nodes toggle is on to enable automatic recovery of failed nodes. The option monitors node statuses. When it detects a non-working node, the autohealer initiates replacement. If one of the machines fails, the application will not stand idle: the node will be replaced, and the app will keep working.
Add as many pools as you need using the Add pool button.
5. Under Network settings, select a network and subnet from existing ones or create a new one.
6. Under SSH key, specify the key that will be added to all nodes for connection.
You can select the key from existing ones or create a new one.
7. Enter the cluster name.
8s. On the right side of the screen, double-check the cluster settings. If everything is correct, click Create cluster.
The cluster will be created in a few minutes!
