v1 Authoring¶

armada/Manifest/v1¶

keyword	type	action
`release_prefix`	string	appends to the front of all charts released by the manifest in order to manage releases throughout their lifecycle
`chart_groups`	array	references ChartGroup document of all groups

Manifest Example¶

---
schema: armada/Manifest/v1
metadata:
  schema: metadata/Document/v1
  name: simple-armada
data:
  release_prefix: armada
  chart_groups:
    - chart_group

armada/ChartGroup/v1¶

keyword	type	action
description	string	description of chart set
chart_group	array	reference to chart document
sequenced	bool	enables sequenced chart deployment in a group
test_charts	bool	run pre-defined helm tests in a ChartGroup (DEPRECATED)

Danger

DEPRECATION: The test_charts key will be removed, as Armada will run helm tests for all charts by default.

Chart Group Example¶

---
schema: armada/ChartGroup/v1
metadata:
  schema: metadata/Document/v1
  name: blog-group
data:
  description: Deploys Simple Service
  sequenced: False
  chart_group:
    - chart
    - chart

armada/Chart/v1¶

Danger

DEPRECATION: timeout key-value will be removed timeout will be defined under wait object.

Chart¶

keyword	type	action
chart_name	string	name for the chart
release	string	name of the release (Armada will prepend with `release-prefix` during processing)
namespace	string	namespace of your chart
wait	object	See Wait.
protected	object	do not delete FAILED releases when encountered from previous run (provide the ‘continue_processing’ bool to continue or halt execution (default: halt))
test	object	See Test.
install	object	install the chart into your Kubernetes cluster
upgrade	object	upgrade the chart managed by the armada yaml
delete	object	See Delete.
values	object	override any default values in the charts
source	object	provide a path to a `git repo`, `local dir`, or `tarball url` chart
dependencies	object	(optional) Override the builtin chart dependencies with a list of Chart documents to use as dependencies instead. NOTE: Builtin “.tgz” dependencies are not yet supported.
timeout	int	time (in seconds) allotted for chart to deploy when ‘wait’ flag is set (DEPRECATED)

Wait¶

keyword	type	action
timeout	int	time (in seconds) to wait for chart to deploy
resources	array	Array of Wait Resource to wait on, with `labels` added to each item. Defaults to pods and jobs (if any exist) matching `labels`.
labels	object	Base mapping of labels to wait on. They are added to any labels in each item in the `resources` array.
native	boolean	See Wait Native.

Wait Resource¶

keyword	type	action
type	string	k8s resource type, supports: controllers (‘deployment’, ‘daemonset’, ‘statefulset’), ‘pod’, ‘job’
labels	object	mapping of kubernetes resource labels
min_ready	int string	Only for controller type``s. Amount of pods in a controller which must be ready. Can be integer or percent string e.g. ``80%. Default `100%`.

Wait Native¶

Config for the native helm (install|upgrade) --wait flag.

keyword	type	action
enabled	boolean	defaults to true

Test¶

Run helm tests on the chart after install/upgrade.

keyword	type	action
enabled	bool	whether to enable/disable helm tests for this chart (default True)
timeout	int	time (in sec) to wait for completion of Helm tests. Default 300.
options	object	See Test Options.

Note

Armada will attempt to run helm tests by default. They may be disabled by setting the enabled key to False.

Danger

DEPRECATION: In addition to an object with the above fields, the test key currently also supports bool, which maps to enabled, but this is deprecated and will be removed. The cleanup option below is set to true in this case for backward compatibility.

Test Options¶

Test options to pass through directly to helm.

keyword	type	action
cleanup	bool	cleanup test pods after test completion, defaults to false

Note

If cleanup is true this prevents being able to debug a test in the event of failure.

Historically, the preferred way to achieve test cleanup has been to add a pre-upgrade delete action on the test pod.

This still works, however it is usually no longer necessary as Armada now automatically cleans up any test pods which match the wait.labels of the chart, immediately before running tests. Similar suggestions have been made for how helm test --cleanup itself ought to work (https://github.com/helm/helm/issues/3279).

Upgrade - Pre¶

keyword	type	action
pre	object	actions performed prior to updating a release

Upgrade - Actions¶

keyword	type	action
update	object	update daemonsets in pre-upgrade update actions
delete	sequence	delete jobs and pods in pre-upgrade delete actions

Upgrade - Actions - Update/Delete¶

keyword	type	action
name	string	name of action
type	string	type of Kubernetes workload to execute in scope for action
labels	object	k:v mapping of labels to select Kubernetes resources

Note

Update Actions only support type: ‘daemonset’

Note

Delete Actions support type: ‘pod’, ‘job’, ‘cronjob’

Defining a Manifest¶

To define your Manifest you need to define a armada/Manifest/v1 document, armada/ChartGroup/v1 document, armada/Chart/v1. Following the definitions above for each document you will be able to construct an armada manifest.

Armada - Deploy Behavior¶

Armada will perform set of pre-flight checks to before applying the manifest - validate input manifest - check tiller service is Running - check chart source locations are valid
Deploying Armada Manifest
1. If the chart is not found
  - we will install the chart
1. If exist then
  - Armada will check if there are any differences in the chart
  - if the charts are different then it will execute an upgrade
  - else it will not perform any actions

Note

You can use references in order to build your charts, this will reduce the size of the chart definition will show example in multichart below
