The TLS opts were missing from helm version command which meant that it
was just perpetually failing and hence wasting 30s of time waiting for a
command to be successful that was never going to be successful. This
never actually caused any errors because this loop will happily just
fail 30 times without breaking the overall script but it was just a
waste of installation time so now installing apps should be ~30s faster.
GitLab uses a kubernetes service account to perform deployments. For
serverless deployments to work as expected with externally created
clusters with their own knative installations (e.g. via Cloud Run), this
account requires additional permissions in the serving.knative.dev API
group.
Both the `install-<app>` and `uninstall-<app>` pods loads the
`values-content-configuration-<app>` configmap into the pod
(see `#volume_specification`). This configmap contains the cert
necessary to connect to Tiller. The cert though is only valid for 30
minutes.
So this fixes the bug where the configmap when uninstalling should be
updated as well.
- Creates new route
- Creates new controller action
- Creates call stack:
Clusterss::ApplciationsController calls -->
Clusters::Applications::UpdateService calls -->
Clusters::Applications::ScheduleUpdateService calls -->
ClusterUpdateAppWorker calls -->
Clusters::Applications::PatchService -->
ClusterWaitForAppInstallationWorker

Use existing `public_url` validation to block various local urls. Note
that this validation will allow local urls if the "Allow requests to the
local network from hooks and services" admin setting is enabled.
Block KubeClient from using local addresses
It will also respect `allow_local_requests_from_hooks_and_services` so
if that is enabled KubeClinet will allow local addresses
Bump the helm and kubectl used in our Kubernetes integration, used e.g.
to install apps.
Note I have only bumped to the latest patch of the v1.11 series for
kubectl as GKE clusters are still on 1.10/1.11
http_max_redirects was introduced in 4.2.2, so upgrade kubeclient.
The monkey-patch was global so we will have to check that all instances
of Kubeclient::Client are handled.
Spec all methods of KubeClient
This should provide better confidence that we are indeed disallowing
redirection in all cases
If the service fails mid-point, then we should be able to re-run this
service. So, detect presence of any previously created Kubernetes
resource and update or create accordingly.
Fix specs accordingly. In the case of finalize_creation_service_spec.rb,
I decided to stub out the async worker rather than maintaining
individual stubs for various kubeclient calls for that worker.
Also add test cases for group clusters
We want to keep failed install pods around so that it is easier to debug
why a failure occured. With this change we also need to ensure that we
remove a previous pod with the same name before installing so that
re-install does not fail.
Another change here is that we no longer need to catch errors from
delete_pod! in CheckInstallationProgressService as we now catch the
ResourceNotFoundError in Helm::Api. The catch statement in
CheckInstallationProgressService was also probably too broad before and
should have been narrowed down simply to ResourceNotFoundError.
When an application install fails, and the user retries install, the
configmap for the application will already exists. If so, we simply
update instead of create.
