# There can only be a single job definition per file. This job is named
# "example" so it will create a job with the ID and Name "example".
# The "job" stanza is the top-most configuration option in the job
# specification. A job is a declarative specification of tasks that Nomad
# should run. Jobs have a globally unique name, one or many task groups, which
# are themselves collections of one or many tasks.
#
# For more information and examples on the "job" stanza, please see
# the online documentation at:
#
# https://www.nomadproject.io/docs/job-specification/job.html
#
job "example" {
# The "region" parameter specifies the region in which to execute the job. If
# omitted, this inherits the default region name of "global".
# region = "global"
# The "datacenters" parameter specifies the list of datacenters which should
# be considered when placing this task. This must be provided.
datacenters = ["dc1"]
# The "type" parameter controls the type of job, which impacts the scheduler's
# decision on placement. This configuration is optional and defaults to
# "service". For a full list of job types and their differences, please see
# the online documentation.
#
# For more information, please see the online documentation at:
#
# https://www.nomadproject.io/docs/jobspec/schedulers.html
#
type = "service"
# The "constraint" stanza defines additional constraints for placing this job,
# in addition to any resource or driver constraints. This stanza may be placed
# at the "job", "group", or "task" level, and supports variable interpolation.
#
# For more information and examples on the "constraint" stanza, please see
# the online documentation at:
#
# https://www.nomadproject.io/docs/job-specification/constraint.html
#
# constraint {
# attribute = "${attr.kernel.name}"
# value = "linux"
# }
# The "update" stanza specifies the job update strategy. The update strategy
# is used to control things like rolling upgrades. If omitted, rolling
# updates are disabled.
#
# For more information and examples on the "update" stanza, please see
# the online documentation at:
#
# https://www.nomadproject.io/docs/job-specification/update.html
#
update {
# The "stagger" parameter specifies to do rolling updates of this job every
# 10 seconds.
stagger = "10s"
# The "max_parallel" parameter specifies the maximum number of updates to
# perform in parallel. In this case, this specifies to update a single task
# at a time.
max_parallel = 1
}
# The "group" stanza defines a series of tasks that should be co-located on
# the same Nomad client. Any task within a group will be placed on the same
# client.
#
# For more information and examples on the "group" stanza, please see
# the online documentation at:
#
# https://www.nomadproject.io/docs/job-specification/group.html
#
group "cache" {
# The "count" parameter specifies the number of the task groups that should
# be running under this group. This value must be non-negative and defaults
# to 1.
count = 3
# The "restart" stanza configures a group's behavior on task failure. If
# left unspecified, a default restart policy is used based on the job type.
#
# For more information and examples on the "restart" stanza, please see
# the online documentation at:
#
# https://www.nomadproject.io/docs/job-specification/restart.html
#
restart {
# The number of attempts to run the job within the specified interval.
attempts = 10
interval = "5m"
# The "delay" parameter specifies the duration to wait before restarting
# a task after it has failed.
delay = "25s"
# The "mode" parameter controls what happens when a task has restarted
# "attempts" times within the interval. "delay" mode delays the next
# restart until the next interval. "fail" mode does not restart the task
# if "attempts" has been hit within the interval.
mode = "delay"
}
# The "ephemeral_disk" stanza instructs Nomad to utilize an ephemeral disk
# instead of a hard disk requirement. Clients using this stanza should
# not specify disk requirements in the resources stanza of the task. All
# tasks in this group will share the same ephemeral disk.
#
# For more information and examples on the "ephemeral_disk" stanza, please
# see the online documentation at:
#
# https://www.nomadproject.io/docs/job-specification/ephemeral_disk.html
#
ephemeral_disk {
# When sticky is true and the task group is updated, the scheduler
# will prefer to place the updated allocation on the same node and
# will migrate the data. This is useful for tasks that store data
# that should persist across allocation updates.
# sticky = true
#
# Setting migrate to true results in the allocation directory of a
# sticky allocation directory to be migrated.
# migrate = true
# The "size" parameter specifies the size in MB of shared ephemeral disk
# between tasks in the group.
size = 300
}
# The "task" stanza creates an individual unit of work, such as a Docker
# container, web application, or batch processing.
#
# For more information and examples on the "task" stanza, please see
# the online documentation at:
#
# https://www.nomadproject.io/docs/job-specification/task.html
#
task "redis" {
# The "driver" parameter specifies the task driver that should be used to
# run the task.
driver = "docker"
# The "config" stanza specifies the driver configuration, which is passed
# directly to the driver to start the task. The details of configurations
# are specific to each driver, so please see specific driver
# documentation for more information.
config {
image = "redis:2.8"
port_map {
db = 6379
}
}
# The "artifact" stanza instructs Nomad to download an artifact from a
# remote source prior to starting the task. This provides a convenient
# mechanism for downloading configuration files or data needed to run the
# task. It is possible to specify the "artifact" stanza multiple times to
# download multiple artifacts.
#
# For more information and examples on the "artifact" stanza, please see
# the online documentation at:
#
# https://www.nomadproject.io/docs/job-specification/artifact.html
#
# artifact {
# source = "http://foo.com/artifact.tar.gz"
# options {
# checksum = "md5:c4aa853ad2215426eb7d70a21922e794"
# }
# }
# The "logs" stana instructs the Nomad client on how many log files and
# the maximum size of those logs files to retain. Logging is enabled by
# default, but the "logs" stanza allows for finer-grained control over
# the log rotation and storage configuration.
#
# For more information and examples on the "logs" stanza, please see
# the online documentation at:
#
# https://www.nomadproject.io/docs/job-specification/logs.html
#
# logs {
# max_files = 10
# max_file_size = 15
# }
# The "resources" stanza describes the requirements a task needs to
# execute. Resource requirements include memory, disk space, network,
# cpu, and more. This ensures the task will execute on a machine that
# contains enough resource capacity.
#
# For more information and examples on the "resources" stanza, please see
# the online documentation at:
#
# https://www.nomadproject.io/docs/job-specification/resources.html
#
resources {
cpu = 500 # 500 MHz
memory = 256 # 256MB
network {
mbits = 10
port "db" {}
}
}
# The "service" stanza instructs Nomad to register this task as a service
# in the service discovery engine, which is currently Consul. This will
# make the service addressable after Nomad has placed it on a host and
# port.
#
# For more information and examples on the "service" stanza, please see
# the online documentation at:
#
# https://www.nomadproject.io/docs/job-specification/service.html
#
service {
name = "global-redis-check"
tags = ["global", "cache"]
port = "db"
check {
name = "alive"
type = "tcp"
interval = "10s"
timeout = "2s"
}
}
# The "template" stanza instructs Nomad to manage a template, such as
# a configuration file or script. This template can optionally pull data
# from Consul or Vault to populate runtime configuration data.
#
# For more information and examples on the "template" stanza, please see
# the online documentation at:
#
# https://www.nomadproject.io/docs/job-specification/template.html
#
# template {
# data = "---\nkey: {{ key \"service/my-key\" }}"
# destination = "local/file.yml"
# change_mode = "signal"
# change_signal = "SIGHUP"
# }
# The "vault" stanza instructs the Nomad client to acquire a token from
# a HashiCorp Vault server. The Nomad servers must be configured and
# authorized to communicate with Vault. By default, Nomad will inject
# The token into the job via an environment variable and make the token
# available to the "template" stanza. The Nomad client handles the renewal
# and revocation of the Vault token.
#
# For more information and examples on the "vault" stanza, please see
# the online documentation at:
#
# https://www.nomadproject.io/docs/job-specification/vault.html
#
# vault {
# policies = ["cdn", "frontend"]
# change_mode = "signal"
# change_signal = "SIGHUP"
# }
# Controls the timeout between signalling a task it will be killed
# and killing the task. If not set a default is used.
# kill_timeout = "20s"
