resolves#4337
Merging maps inside of strings gets a bit tricky. When two
strings consisting of "{}" were being added together, this resulted in
"{}\n{}" instead of "{}" which is what we wanted. This led to YAML
parsing errors and showed up when the `--reuse-values` flag was used
when no overrides via `--set` were provided during install and/or
upgrade.
If `helm upgrade` fails because a reused name is still in use, the error
message does not specify which name is still in use. Update the error
message.
Address a race condition that arises when running two `helm install`
commands, both of which specify a namespace that does not already exist.
In this specific instance, attempting to create a `namespace` which
already exists shouldn't be a failure which causes `helm install` to
terminate.
This adds support for installing CRDs well before any other resource
kinds are installed.
This PR introduces a new hook, `crd-install`, that fires before
manifests are even validated. It is used to install a CRD before any
other part of a chart is installed.
Currently, this hook is _only implemented for install_. That means we
currently cannot add new CRDs during `helm upgrade`, nor can they
be rolled back. This is the safest configuration, as the update/rollback
cycle gets very challenging when CRDs are added and removed.
Resolves#3655
We were seeing that when running helm upgrade with the reuse-values
flag enabled that you could end up in the position where overrides
a.k.a computed values from previous revisions were not being saved on
the updated revision. This left us in a weird position where some
computed values would disappear mysteriously in the abyss. That
happened because computed values from previous revisions weren't merged
with the new computed values every time the reuse-values flag was used.
This PR merges computed values from the previous revisions so you don't
end up in that kind of conundrum.
Existing helm.sh/hook-delete-policy annotation variables (hook-failed, hook-succeeded) do not allow to leave failed jobs for debugging without blocking the next job launching: every failed job must be deleted manually before the next related release is launching (installing, updating or rolling back).
New policy, before-hook-creation, removes the hook from previous release if there is one before the new hook is launched and can be used with another variable.
When using `helm upgrade --install`, if the first release fails, Helm will respond with an error saying that it cannot upgrade from an unknown state.
With this feature, `helm upgrade --install --force` automates the same process as `helm delete && helm install --replace`. It will mark the previous release as DELETED, delete any existing resources inside Kubernetes, then replace it as if it was a fresh install. It will then mark the FAILED release as SUPERSEDED.
* add test for rolling back from a FAILED deployment
* Update naming of release variables
Use same naming as the rest of the file.
* Update rollback test
- Add logging
- Verify other release names not changed
* fix(tiller): Supersede multiple deployments
There are cases when multiple revisions of a release has been
marked with DEPLOYED status. This makes sure any previous deployment
will be set to SUPERSEDED when doing rollbacks.
Closes#2941#3513#3275
Between grpc 1.2.x and 1.7.x there was an API change. The
previous MaxMsgSize is now a wrapper around MaxRecvMsgSize. This
change now sets the MaxRecvMsgSize and MaxSendMsgSize which need
to be set independently.
Fixes#2437
Two bugs were causing this behavior
- Tiller was marking the previous release superseded when an upgrade
failed.
- Upgrade was diffing against failed releases
When release upgrade fails, updatedRelease is already created
in a storage by *ReleaseServer.UpdateRelease, therefore we should
be updating it's status, not creating it again.
