Prerequisites
Ondat requirements to be executed. Hardware, Network rules, Operative System Distribution, Kernel modules, etc.
Prerequisites for using Ondat
Minimum requirements
One machine with the following:
- Minimum two core with 4GB RAM
- Linux with a 64-bit architecture
- Kubernetes 1.19 - 1.23
- Container Runtime Engine: CRI-O, Containerd or Docker 1.10+ with mount propagation enabled
- The necessary ports should be open. See the ports and firewall settings
- Etcd cluster for Ondat
- A mechanism for device presentation
Recommended
- Prepare a cluster with minimum of 5 nodes when running etcd within Kubernetes for replication and high availability; 3 nodes if etcd is outside Kubernetes or a self-eval cluster
- Install the Ondat CLI
- If using Helm2, make sure the tiller ServiceAccount has enough privileges to create resources such as Namespaces, ClusterRoles, etc. For instance, following this installation procedure
- System clocks synchronized using NTP or similar methods. While our distributed consensus algorithm does not require synchronised clocks, it does help to more easily correlate logs across multiple nodes
- A PID cgroup limit of 32768
- Some aspects of product operation require kernel support for IPv6. See the IPv6 prequisites page
