The Nomad UI received a number of upgrades: Visit the Nomad OpenAPI GitHub repository for information on how to contribute or write an integration of your own. Golang, Java, JavaScript, Python, Ruby, Rust, and TypeScript clients have already been generated. Nomad endpoints are described using the OpenAPI (Swagger) spec, allowing for automatic generation of documentation and SDKs in various languages. So, in case you missed it, here are some of these recent improvements: » OpenAPI Support Some of these improvements deserve mention even though they were released prior to Nomad 1.3. Since Nomad 1.2 was released in November 2021, we have made some exciting new additions to Nomad and its ecosystem. See the Nomad 1.3 Changelog for a full list of changes. Fingerprinting is supported on Digital Ocean Droplets.Task drivers can now be enabled or disabled for specific namespaces.API endpoints for jobs, volumes, allocations, evaluations, deployments, and tokens now support pagination and a new filter parameter, allowing for more specific and efficient API queries.Support for Linux Control Groups (cgroups) V2.Easier API requests from the command line with nomad operator api.The address can be an IP address or domain name. A new address field in the service stanza that allows Nomad or Consul services to be registered with a custom.Nomad 1.3 also includes various quality of life improvements and bug fixes. To get started, check out the Nomad Pack repository on GitHub, or read the Nomad Pack HashiCorp Learn guides for a walkthrough of using and extending Nomad Pack. Nomad Pack helps you easily run common applications, templatize your applications, and share configuration with the Nomad community. Users on macOS can now install Nomad Pack using Homebrew with brew install nomad-pack, making it easier to start using packs.Īdditionally, Nomad Pack has new template helper methods and better error messages, among other improvements. These pages allow Nomad operators to troubleshoot their Nomad cluster quickly using the UI, instead of exclusively relying on the CLI or API for evaluation information. A visual display of related evaluations.Selecting an evaluation reveals details including: Evaluations can be filtered by status and type, and searched for by evaluation ID, related job ID, related node ID, or the reason for triggering. This allows Nomad users to quickly view the status of recent evaluations for the entire cluster, and dig into information on a specific evaluation.Ĭlicking on the new “Evaluations” link in the sidebar will show you a list of recent evaluations across all the jobs you can see in your cluster. Nomad 1.3 introduces a new user interface for viewing evaluation information. We want to thank everyone in the Nomad community for their patience and invaluable feedback while CSI was in beta. With these features, stability improvements, and bug fixes, CSI is ready to be used for production workloads on Nomad. $ nomad volume snapshot list -secret someKey =someValue This request is passed to the EBS CSI provider, which properly places the volume in this availability zone. For instance, the code shown below from a volume.hcl file using the AWS EBS CSI driver sets the volumes to be mounted in the zone "us-east-1b". This is useful when you want to specify where a CSI volume should be placed within your cluster. Nomad CSI now supports the topology feature. With Nomad 1.3, we are excited to announce that support for CSI is now generally available. Nomad's Container Storage Interface integration can manage external storage volumes for stateful services running inside your cluster. Upon reconnecting, the client’s allocations will restart if they have not been rescheduled elsewhere. If the client node is disconnected for longer than the max_client_disconnect duration, Nomad will mark the client node as down and the allocations as lost. The client’s allocations will gracefully transition back from unknown to running without restarting as they would in previous versions of Nomad. If the node reconnects before the max_client_disconnect duration ends, it will transition back to ready status. If max_client_disconnect is set on an allocation, and a client node has been disconnected for longer than heartbeat_grace but less than the max_client_disconnect duration, Nomad sets the client node status to disconnected and its allocations’ statuses to unknown. Http īy default, if max_client_disconnect is not set and a node fails its heartbeat, Nomad sets the node status as down at the server and marks the allocations as lost.
