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]

• 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]
• core: Added support for spreading allocations across a specific attribute. Operators can specify spread target percentages across failure domains such as datacenter or rack [GH-4512]
• core: Added preemption support for system jobs. System jobs can now preempt other jobs of lower priority. See preemption for more details. [GH-4794]

• drivers: Added total memory usage to task resource metrics [GH-5190]
• server/rpc: Reduce logging when undergoing temporary network errors such as hitting file descriptor limits [GH-4974]
• server/vault: Tweaked logs to better identify vault connection errors [GH-5228]
• server/vault: Added Vault token expiry info in nomad status CLI, and some improvements to token refresh process [GH-4817]

• All jobs that interpret variables in constraints or driver configurations will need to be updated to the new syntax which wraps the interpreted variable in curly braces. ($node.class becomes ${node.class}) [GH-760]
