Fail to create install-config.yaml for Openshift

[DerekYeo]

Hi all expert,

I am beginner to the openshift world and now learning how to deploy it. I currently failed to create the install-config.yaml file on my vsphere platform. Can you please show me how to create this file?

Is there a command to create the file OR is it just normal linux VI command to create? Please advise

Hi,

Have you seen the official documentation that describes how to manually create the install-config.yaml file? It even has a sample file for VSphere: 

https://docs.openshift.com/container-platform/4.1/installing/installing_vsphere/installing-vsphere.h...

Hi beelandc, Tq for the reply. I have gone through this document but dont really understand how to create it. Is the install-config files created using the ./openshift-install command? Or is it just #vi install-config.yaml and configure the parameters?

Hey, @DerekYeo,

Both options are possible, but probably the easiest is to use openshift-install to generate the install-config.yaml file like this:

$ ./openshift-install create install-config

Then edit it to suit your taste and install the cluster:

$ ./openshift-install create cluster

Be careful though - if you want to preserve a copy of install-config.yaml, make a backup as it gets deleted during the installation process.

Cheers,
Grega

install-config.yaml is simply a yaml file, so you can create it manually if you want/need to. The instructions I linked to describe how to manually create the file. You would use VI or whatever is the text editor of your choice.

However, as benko noted, you can use the ./openshift-install command to generate an initial version of the file, and then edit that file in a text editor to match your desired configuration

Now i get this error after creating the install-configs.yaml file. Did i miss any steps?

This is my install-configs.yaml file.

@DerekYeo I'm not entirely sure what is causing the error and don't have an OCP 4 environment to test right now, but I would definitely check your indentations in your install-config.yaml file. Since indentations in YAML indicate scope, it can be particular about that.

The indentation is different than yours in the example vsphere install-config file(1) in our documentation. Specifically, the number of spaces that are indented, and the fact that the attributes under "vsphere" should be indented further. I also don't see a "vcenter" line in yours:

Finally got it work. 

Its really just a syntax error. I found this website which is good to debug yaml syntax. http://www.yamllint.com/.

Thanks for all the advises and help. Appreciate it very much!
