Content of the file /sys/hypervisor/uuid starts with “ec2”.For example, to check whether Hazelcast runs on AWS EC2 Instance, we check 3 conditions and they all need to be satisfied: Member :5701 - d24d06f8-3ff8-4484-bdb4-759b2d459270ĭetecting each cloud environment requires checking some environment-specific properties. kubectl logs hazelcast-1Īuto-detection selected discovery strategy: class You can check that the Hazelcast cluster was formed. That’s it, Hazelcast instances automatically discovered each other using the Kubernetes Discovery plugin with default parameters. Kubectl run hazelcast-2 -image=hazelcast/hazelcast Kubectl run hazelcast-1 -image=hazelcast/hazelcast Then, you can start a few Hazelcast instances and they’ll form one Hazelcast cluster. To start Hazelcast on Kubernetes, you need to apply the needed RBAC. Hazelcast members automatically discovered themselves using the GCP Discovery plugin with default parameters. hz startĪuto-detection selected discovery strategy: class Then, execute the following command on each of your VM Instances. Configure access to Cloud APIs (at minimum Read Only to Compute Engine API).To start Hazelcast on GCP VM Instances, you have to perform the following steps for each instance: Hazelcast members automatically discovered themselves using the Azure Discovery plugin with default parameters. Then, execute the following command on each of your Virtual Machines. Attach Azure managed identity with the READ role.To start Hazelcast on Azure Virtual Machines, you have to perform the following steps for each VM: For a more detailed description you can also check Hazelcast Guides: Deploy Hazelcast Cluster on AWS EC2. That’s it! Hazelcast automatically detected that it is running on an EC2 Instance and used the AWS Discovery Plugin with default parameters (finding all Hazelcast members within the same region). Now, execute the following command on each of the EC2 Instances. Configure IAM Role assigned to EC2 Instance to allow the ec2:DescribeInstances permission.Configure Security Groups to open port 5701 (the default Hazelcast port).To start Hazelcast on AWS EC2 Instances, you have to perform the following steps for each instance: You can also check Hazelcast Reference Manual: Discovering Members by Auto Detection to find more about the requirements for the discovery auto-detection. In this blog post, I walk through common cloud environments and explain how auto-detection works in each of them. What’s more, we made it all extensible, so if you develop any discovery plugin by yourself, you can make your plugin auto-discoverable. Hazelcast can now automatically discover the environment it is running in and find a suitable discovery plugin. With the IMDG 4.1 release, however, we went one step further in making Hazelcast as user friendly as possible. Hazelcast was always well integrated with all cloud environments thanks to discovery plugins like Hazelcast AWS Plugin or Hazelcast Kubernetes Plugin.
