How to fix - Helm install unknown flag --name/Error must either provide a name or specify --generate-name?
In Helm v3 you must use release name along with chart name in the command otherwise it will result into the following errors -
Error 1- Helm install unknown flag --name
Error 2- Error: must either provide a name or specify --generate-name
Lets look at Error 1 - Caused by incorrect use of name flag
This --name
flag is no longer supported by the Helm v3, so if you are trying to use it somewhere in your helm
commands then it will not work.
Error 1- Helm install unknown flag --name
The above error is caused by the --name
flag used in the Helm command (You should not use --name
flag.)
Considering the error most probably your incorrect helm command should look like this -
1helm install helloWorld --name helloWorldRelease
Lets look at Error 2 - Caused by missing 'release name'
This error is also very similar to Error 1 but you most probably missing release name
in the command.
Here is an example of incorrect command where you did not mention release name
-
1helm install helloWorld
In the above command helloWorld
is my Helm Chart.
Once you run the above incorrect command it will result into following error
Error 2- Error: must either provide a name or specify --generate-name
How to fix both the errors?
Here is the correct example of the command -
1helm install helloWorldRelease helloWorld
In the above command -
Args | Name | |
---|---|---|
1 | Release name | helloWorldRelease (Note : - You can write any name of your choice) |
2 | Chart name | helloWorld |
Helm auto-generate release name (In case if you want helm to auto to generate the release name)
By default Helm v3 will not auto-generate the release name. If you want Helm to auto-generate name then you must
supply auto-generate
flag along with your command.
Look at the following example (In this example I am not supplying release name)-
1helm install --generate-name helloWorld
Here is the breakdown of above command -
Args | Name | |
---|---|---|
1 | Release name | NO NEED OF RELEASE NAME HELM WILL AUTO GENERATE |
2 | Chart name | helloWorld |
You can verify the release name
after running the installation command -
1helm list -a
Here is the status of the Helm install -
1NAME NAMESPACE REVISION UPDATED STATUS CHART APP VERSION
2helloworld-1609923884 default 1 2021-01-06 09:04:45.188824802 +0000 UTC deployed helloworld-0.1.0 1.16.0
As you can see helloworld-1609923884
is the auto generated name by Helm.
