1.3.1 (May 19, 2022)

SECURITY:

A vulnerability was identified in the go-getter library that Nomad uses for its artifacts such that a specially crafted Nomad jobspec can be used for privilege escalation onto client agent hosts. CVE-2022-30324 [GH-13057]

BUG FIXES:

agent: fixed a panic on startup when the server.protocol_version config parameter was set [GH-12962]

1.3.0 (May 11, 2022)

FEATURES:

Edge compute improvements: Added support for reconnecting healthy allocations when disconnected clients reconnect. [GH-12476]
Native service discovery: Register and discover services using builtin simple service discovery. [GH-12368]

BREAKING CHANGES:

agent: The state database on both clients and servers will automatically migrate its underlying database on startup. Downgrading to a previous version of an agent after upgrading it to Nomad 1.3 is not supported. [GH-12107]
client: The client state store will be automatically migrated to a new schema version when upgrading a client. Downgrading to a previous version of the client after upgrading it to Nomad 1.3 is not supported. To downgrade safely, users should erase the Nomad client's data directory. [GH-12078]
connect: Consul Service Identity ACL tokens automatically generated for Connect services are now created as Local rather than Global tokens. Nomad clusters with Connect services making cross-Consul datacenter requests will need to ensure their Consul agents are configured with anonymous ACL tokens of sufficient node and service read permissions. [GH-8068]
connect: The minimum Consul version supported by Nomad's Connect integration is now Consul v1.8.0. [GH-8068]
csi: The client filesystem layout for CSI plugins has been updated to correctly handle the lifecycle of multiple allocations serving the same plugin. Running plugin tasks will not be updated after upgrading the client, but it is recommended to redeploy CSI plugin jobs after upgrading the cluster. [GH-12078]
raft: The default raft protocol version is now 3 so you must follow the Upgrading to Raft Protocol 3 guide when upgrading an existing cluster to Nomad 1.3.0. Downgrading the raft protocol version is not supported. [GH-11572]

SECURITY:

0.9.2 (June 5, 2019)

SECURITY:

driver/exec: Fix privilege escalation issue introduced in Nomad 0.9.0. In Nomad 0.9.0 and 0.9.1, exec tasks by default run as nobody but with elevated capabilities, allowing tasks to perform privileged linux operations and potentially escalate permissions. (CVE-2019-12618) [GH-5728]

BACKWARDS INCOMPATIBILITIES:

api: The api package removed Config.SetTimeout and Config.ConfigureTLS functions, intended to be used internally only. [GH-5275]
api: The job deployments endpoint now filters out deployments associated with older instances of the job. This can happen if jobs are purged and recreated with the same id. To get all deployments irrespective of creation time, add all=true. The nomad job deploymentCLI also defaults to doing this filtering. [GH-5702]
client: The format of service IDs in Consul has changed. If you rely upon Nomad's service IDs (not service names; those are stable), you will need to update your code. [GH-5536]
client: The format of check IDs in Consul has changed. If you rely upon Nomad's check IDs you will need to update your code. [GH-5536]
client: On startup a client will reattach to running tasks as before but will not restart exited tasks. Exited tasks will be restarted only after the client has reestablished communication with servers. System jobs will always be restarted. [GH-5669]

FEATURES:

core: Add nomad alloc stop command to reschedule allocs [GH-5512]
core: Add nomad alloc signal command to signal allocs and tasks [GH-5515]
core: Add nomad alloc restart command to restart allocs and tasks [GH-5502]

driver/exec: Fix an issue where raw_exec and exec processes are leaked when nomad agent is restarted [GH-5598]

0.9.0 (April 9, 2019)

BACKWARDS INCOMPATIBILITIES:

core: Drop support for CentOS/RHEL 6. glibc >= 2.14 is required.
core: Switch to structured logging using go-hclog. If you have tooling that parses Nomad's logs, the format of logs has changed and your tools may need updating.
core: IOPS as a resource is now deprecated [GH-4970]. Nomad continues to parse IOPS in jobs to allow job authors time to remove iops from their jobs.
core: Allow the != constraint to match against keys that do not exist [GH-4875]
client: Task config validation is more strict in 0.9. For example unknown parameters in stanzas under the task config were ignored in previous versions but in 0.9 this will cause a task failure.
client: Task config interpolation requires names to be valid identifiers (node.region or NOMAD_DC). Interpolating other variables requires a new indexing syntax: env[".invalid.identifier."]. [GH-4843]
client: Node metadata variables must have valid identifiers, whether specified in the config file (client.meta stanza) or on the command line (-meta). [GH-5158]
driver/lxc: The LXC driver is no longer packaged with Nomad and is instead distributed separately as a driver plugin. Further, the LXC driver codebase is now in a separate repository. If you are using LXC, please follow the 0.9.0 upgrade guide as you will have to install the LXC driver before conducting an in-place upgrade to Nomad 0.9.0 [GH-5162]

FEATURES:

Affinities and Spread: Jobs may now specify affinities towards certain node attributes. Affinities act as soft constraints, and inform the scheduler that the job has a preference for certain node properties. The new spread stanza informs the scheduler that allocations should be spread across a specific property such as datacenter or availability zone. This is useful to increase failure tolerance of critical applications.
System Job Preemption: System jobs may now preempt lower priority allocations. The ability to place system jobs on all targeted nodes is critical since system jobs often run applications that provide services for all allocations on the node.
Driver Plugins: Nomad now supports task drivers as plugins. Driver plugins operate the same as built-in drivers and can be developed and distributed independently from Nomad.
Device Plugins: Nomad now supports scheduling and mounting devices via device plugins. Device plugins expose hardware devices such as GPUs to Nomad and instruct the client on how to make them available to tasks. Device plugins can expose the health of devices, the devices attributes, and device usage statistics. Device plugins can be developed and distributed independently from Nomad.
Nvidia GPU Device Plugin: Nomad builds-in a Nvidia GPU device plugin to add out-of-the-box support for scheduling Nvidia GPUs.
Client Refactor: Major focus has been put in this release to refactor the Nomad Client codebase. The goal of the refactor has been to make the codebase more modular to increase developer velocity and testability.
Mobile UI Views: The side-bar navigation, breadcrumbs, and various other page elements are now responsively resized and repositioned based on your browser size.
Job Authoring from the UI: It is now possible to plan and submit new jobs, edit existing jobs, stop and start jobs, and promote canaries all from the UI.
Improved Stat Tracking in UI: The client detail, allocation detail, and task detail pages now have line charts that plot CPU and Memory usage changes over time.
Structured Logging: Nomad now uses structured logging with the ability to output logs in a JSON format.

IMPROVEMENTS:

core: Added advertise address to client node meta data [GH-4390]
core: Added support for specifying node affinities. Affinities allow job operators to specify weighted placement preferences according to different node attributes [GH-4512]

0.8.0 (April 12, 2018)

BACKWARDS INCOMPATIBILITIES:

cli: node drain now blocks until the drain completes and all allocations on the draining node have stopped. Use -detach for the old behavior.
client: Periods (.) are no longer replaced with underscores (_) in environment variables as many applications rely on periods in environment variable names. [GH-3760]
client/metrics: The key emitted for tracking a client's uptime has changed from "uptime" to "client.uptime". Users monitoring this metric will have to switch to the new key name [GH-4128]
discovery: Prevent absolute URLs in check paths. The documentation indicated that absolute URLs are not allowed, but it was not enforced. Absolute URLs in HTTP check paths will now fail to validate. [GH-3685]
drain: Draining a node no longer stops all allocations immediately: a new migrate stanza allows jobs to specify how quickly task groups can be drained. A -force option can be used to emulate the old drain behavior.
jobspec: The default values for restart policy have changed. Restart policy mode defaults to "fail" and the attempts/time interval values have been changed to enable faster server side rescheduling. See restart stanza for more information.
jobspec: Removed compatibility code that migrated pre Nomad 0.6.0 Update stanza syntax. All job spec files should be using update stanza fields introduced in 0.7.0 [GH-3979]
