While trying to add/update a dependency to a helm chart I'm getting this error. No helm plugins are installed with the name helm-manager.
$ helm dep update

The stable and incubator repositories of the Helm charts have been moved to a new location.
You must updated URI in charts.yaml (or requirements.yaml) to point to the new repositories in order to let the Helm dependency resolver find the correct location.
Name
Old Location
New Location
stable
https://kubernetes-charts.storage.googleapis.com
https://charts.helm.sh/stable
incubator
https://kubernetes-charts-incubator.storage.googleapis.com
https://charts.helm.sh/incubator
After that you should be able to run helm dep update without further modifications.
I get this sometimes when there's a mismatch between my Chart.yaml and the configuration of my subchart dependencies.
For instance:
Chart.yaml:
dependencies:
- name: foo
...
- name: bar
...
values.yaml:
foo:
flag: true
# but no entry for bar
It may be an artifact of some other element of my configuration (Artifactory hosting a proxy of the world for Helm) but I find myself running into this frequently enough that I hope this answer may help someone else.

I am trying to create a helm based operator and for most part, I've got it working. However I need to make sure that the subcharts are installed before the operator is trying to create resources from those subcharts. For e.g I have mongodb community-operator helm chart as a subchart. However, when I deploy the operator i get the below error
failed to install release: unable to build kubernetes objects from release manifest: resource mapping not found for name: "test-mongodb" namespace: "default" from "": no matches for kind "MongoDBCommunity" in version "mongodbcommunity.mongodb.com/v1"
ensure CRDs are installed first.
Looks like its trying to create the mongodb instance before actually installing the operator and crds. How can I force it to first install the subcharts and then try to create mongodb instance.
inside the chart.yaml you can use the condition & tag
dependencies:
- name: subchart
version: 0.0.1
repository: https://chart.github.io/helm-charts
condition: subchart.enabled
so if the chart name as subchart is not installed already in cluster it will throw the error.
Official doc : https://helm.sh/docs/chart_best_practices/dependencies/
if you have multiple sub charts as dependencies you can also go with the tags
When I run " helm upgrade ." , new modified changes in dependencies list are not updating.
Process we followed : Post doing required changes to the existing values file in helm chart, packaging it using "helm package ." and pushing packaged tar to s3 using s3 plugin.
In the another parent helm chart, we are mentioning above packaged tar file details like name,version and s3 repository link under dependencies list in requirements.yaml file.
successfully executing the helm dependency update also .
later, when executing helm upgrade it is showing like
client.go:229: [debug] checking 38 resources for changes
client.go:512: [debug] Looks like there are no changes
Helm unable to identify the new changes made to the dependencies list.
Please help to fix issue
I have a Helm Umbrella Chart that I'm trying to write which has dependencies on 2 charts (for simplicity's sake). Chart A and Chart B. Both Chart A and Chart B have defined dependencies on Chart C. When I'm writing the Umbrella chart I specify a dependency on Chart A and B. When I try to install my Umbrella chart I get an error:
Error: INSTALLATION FAILED: serviceaccounts "chart-c" already exists
My guess is this is happening because both Chart A and Chart B are trying to install the Chart C app. How do I manage these dependencies in my Umbrella Chart?
I think you can do that with alias.
Example: In the dependencies section of the Chart.yaml file.
dependencies:
- name: mongodb
version: 12.1.2
repository: https://charts.bitnami.com/bitnami
alias: mongodb
condition: mongodb.enabled
- name: mongodb
version: 12.1.2
repository: https://charts.bitnami.com/bitnami
alias: mongodb-tracing
condition: mongodb-tracing.enabled
You can read more about alias here
I am trying to add a rabbitmq service using a bitnami helm chart. the chart contains one dependent helm chart which is called common.
The whole application itself is deployed using a parent helm chart and each service has its own separate helm chart.
the Helm chart structure looks like this-
\myapp
\charts
\service1
\service2
\service3
\messaging
\charts
\common
\templates
\chart.yml
\values.yml
When i ran "helm dependency update" from the 'messaging' dir, it downloaded a common-1.x.x.tgz file. i extracted the contents and placed it in the \messaging\charts\common folder
the original messaging\templates\chart.yml (rabbitmq helm chart) contained the following entry
dependencies:
- name: common
repository: https://charts.bitnami.com/bitnami
tags:
- bitnami-common
version: 1.x.x
because i cannot download during the "Helm install" execution i had to download the dependent helm charts beforehand and save them as a local dependency. After downloading the common.tgz file, i extracted the contents and updated the dependencies in the messaging\templates\chart.yml as follows
dependencies:
- name: common
repository: 'file://charts/messaging/charts/common'
tags:
- bitnami-common
version: 1.x.x
If i do "helm install messaging ." from \myapp\charts\messaging directory, the service gets deployed without any error. But when the application's parent helm chart is deployed i always get this error
"Error: found in Chart.yaml, but missing in charts/ directory: messaging"
Can someone please point out the mistake in the configuration? I moved around the contents of the common folder around multiple location, had them as tgz file, updated the repository path relative to the messaging directory instead of parent helm chart location, but in all cases, the installation of the messaging service fails with the above error
You don't need to unpack the charts/*.tgz file. If they're in that directory (and still packed up) then Helm will use them to run the deployment. Helm won't contact the external chart repository on its own, only when you run the helm dependency commands.
After you run helm dep up your filesystem layout should look like
myapp
\-- charts
\-- messaging
+-- charts
| \-- rabbitmq-8.15.3.tgz
|-- templates
| +-- deployment.yaml
| \-- service.yaml
+-- Chart.yaml
\-- values.yaml
You're ready to go in this state. Don't unpack anything.
If you need to copy this setup across a network boundary, include the charts/*.tgz files when you do it. It doesn't matter that Chart.yaml or requirements.yaml references an Internet location; helm install will only use those local archives.
I had a similar issue and it was because a developer had placed the Charts and templates etc in the charts directory. I kept getting errors saying it couldn't find directories so moved all the charts into a helm-charts directory instead as the charts directory is managed by Helm. When I updated the repository listing to pull from the new directory, my issue was resolved. I got the idea from this issue's comments and it worked. https://github.com/helm/helm/issues/2887
I'm using helm charts to deploy around 15 microservices. There is a parent helm chart with requirements.yaml where the all the required microservices are listed as dependencies.
Sample requirements.yaml file:
dependencies:
- name: service1
repository: "#stable"
version: <version>
- name: service2
repository: "#stable"
version: <version>
- name: service3
repository: "#stable"
version: <version>
- name: service4
repository: "#stable"
version: <version>
condition: false
When I run helm dependency update all the charts that are listed as dependency are downloaded. There are scenarios where few services are under development and are not required to be deployed in production.
We have different artifactory for prod and non-prod environment and the disabled services are not in prod artifactory. Hence it gives an error saying helm chart missing. I understand that the condition flag doesn't install the dependency but how can I stop it from downloading the dependency ?
It might come a bit late, but I sorted out a similar problem recently and I thought it might help others to share. You can use the condition key when declaring dependencies in your Chart.yaml:
dependencies:
- condition: gitea.cache.builtIn.enabled
name: memcached
repository: https://charts.bitnami.com/bitnami
version: 4.2.20
With the bit in values.yaml being as follows:
[...]
gitea:
cache:
builtIn:
enabled: true
[...]
This example is extracted from the fantastic gitea helm chart repo and should be self explanatory. However, you can take a look at Helm documentation
Be aware that if there are nested charts more than 2 levels deep, helm2 might misbehave so I recommend you to take a look at Helm3 for that.
Finally please note that in my case (as I'm following a small detour when deploying Helm charts, the check for the condition happens when rendering the helm chart not when running helm dependency update
