This builds on previous work and adds more logging to follow
the full process of installing, updating, deleting, and rolling back.
This also standardizes capitalization of logs and small formatting
fixes
Extracted delete specific code from ReleaseServer to external function
which is called from both Local and Remote ReleaseModules.
Made getVersionSet function from tiller package exported.
This change introduces the concept of Rudders - pluggable modules that
Tiller communicates with via grpc, which allow to decouple orchestration
logic from Tiller into separate service.
This commit consists of simple Rudder implementation which does exactly
the same thing as built in Tiller orchestrator - it creates all k8s
objects from provided manifest without orchestrating them.
--experimental-release flag is introduced to enable this behaviour.
This change allows to use the service and tiller outside of the cluster.
Following commits will add Rudder to helm deployment.
Adds an `unreleased` flag to the version if not building from HEAD of a
tag. The compatibility check is bypassed if the client or server are
unreleased.
fixes#2110
Environment is supplied with release lock map which allows to lock a
release by name to make sure that update, rollback or uninstall aren't
running on one release at the same time.
It is now possible to create plugins with chart download capabilities for custom, non-http protocols.
Furthermore it is possible to reuse helm packages to implement alternative clients with these custom downloader functions.
This provides the Chart.yaml field `tillerVersion`, which is a semver
range. It allows users to choose to constrain a chart to a specific
version.
The reason for this is that we keep introducing new template functions,
but we have no way of saying "this chart will only work with Tiller
newer than...".
The check on version is _only_ done on Tiller. The client does not check
at all, since it does not do any template expansion on its own.
The following kinds are newly addressed:
CronJob
LimitRange
ReplicaSet
ResourceQuota
StatefulSet
Furthermore, adjust the installation and uninstallation order to
better respect likely dependencies. Bare pods remain a difficult one
to place properly in both sequences.
During installation and uninstallation, handle the RBAC-related
ClusterRole, ClusterRoleBinding, Role, and RoleBinding kinds in an
order that respects their potential referential integrity, namely that
ClusterRoleBindings can refer to ClusterRoles and ServiceAccounts, and
RoleBindings can refer to ClusterRoles, Roles, and ServiceAccounts.
Fixes#2199.

* Adds new annotation `helm.sh/hookWeight`
* Sorts executing hooks of similar kind in ascending order
* There is no upper or lower bounds on the weights
Most newcomers hit helm's 'feature' there deleted instalations are not really deleted.
Use-case
# helm install --name gitlab-ce-1 ./stable/gitlab-ce
# helm delete gitlab-ce-1
# helm list
# helm install --name gitlab-ce-1 ./stable/gitlab-ce
Error: a release named "gitlab-ce-1" already exists
There is a lot duplicated bugs in bugzilla which simply explains that packages
should be deleted with --pure flag. But such bugs appeared again and again
because this behavior is not obvious.
Let's help user to figure out what happens ASAP.
Users can now specify a namespace filter for 'helm list'. Only the
releases within the specified namespace will be shown. For example,
'helm list --namespace foo' will only show releases for the 'foo'
namespace. Also added a namespace field to the table view.
Closes#1563
At the present time, PersistentVolumeClaims are not a recognized object so it is installed last.
PVCs should be installed shortly after PersistentVolumes have been bound.
* This is a simple mvp which processes a test definition with the
hook annotation for test when you run `helm test [release]`
* helm client cmd, proto def, tiller logic
The --reset-values flag on upgrade instructs Tiller to reset the
upgraded release to the chart's built-in values.yaml, and ignore the
last install's overridden values.
Closes#1569
This adds the {{.Capabilities}} object to the template variables so that
chart authors can write charts that are aware of teh Kubernetes
capabilities of the current cluster.
Closes#1608
Installs, rollback, upgrade, and delete now accept a `--timeout` flag
that allows the user to specify the maximum number of seconds that
any kubernetes command can take.
Closes#1678
There are some places where releases are only located if they are in the
state DEPLOYED. That particular logic was incorrectly used for upgrades.
That caused #1566. While fixing that issue, I found that this was also
the root cause of #1587 (though because it was off by one). I added a
generic method to get the last release, regardless of its status.
This allows some behaviors that previously failed:
- 'helm upgrade' can now be performed on a DELETED release
- 'helm rollback' can now be performed on a DELETED release even if
there is only one revision of that release history.
Closes#1566Closes#1587
This adds a hidden 'helm doc' command that generates documentation out
of the Helm help text.
Currently it can create:
- man pages for HELM(1)
- Markdown documentation
- bash autocompletions
Those are the three built-ins for Cobra.
The command is hidden so that it doesn't show up to the regular user,
since this is really a specialized task. It has the advantage of making
it trivially easy to install man pages and bash completion at installation time.
There were several places where an invalid name could be interpreted
into a wild-card by Kubernetes. That allows Bad Things.
This fix requires names to match the Kubernetes pattern for naming.
Closes#1594
This does the following to improve deletion failure handling:
- In an UninstallRelease operation, the release is marked DELETED
as soon as the basic checks are passed. This resolves 1508. I filed a
followup issue for doing this even better when we can modify protos
again.
- If a YAML manifest fails to parse, the error messages now suggests
that the record is corrupt, and the resources must be manually
deleted.
- If a resource is missing during deletion, the error messages now make
it clear that an object was skipped, but that the deletion continued.
Closes#1508
