"No region available" when adding a new environment to new CDP public Cloud

meiravR — Mon, 03 Aug 2020 13:18:56 GMT

Hi all,

I'm pretty new with CDP of any kind. I need to set up a CDP Public Cloud instance for some research. I'm following this documentation and I'm running into issues when trying to add a new AWS environment. Here are the steps I took:

1. When I reached Region, Networking, Security, and Storage section of environment registration no region was available to choose:

2. I restarted the registration process with a different environment name and this time the region was identified for the AWS account ID and the SSH keypair I created was discovered. However, the "next" button on the Region, Networking, Security and Storage section was still locked from use.

3. I tried restarting again with a new environment name, and this time the region name was undiscovered again, but this time trying to find the region timed out and I got this error message:

How can I get over these technical issues?

Thank you.

Hello @meiravR ,

thank you for reporting your experience having difficulty adding a new environment to the CDP public cloud.

During the process of creating CDP credential, we need to copy and paste texts that contain special characters. Just to narrow down the possible cause of the issue, can you please confirm if you used any text editor to paste these values (e.g. for documentation purposes) and copied it back to the browser?

I would like to rule out the possibility that encodings changed between copying and pasting, hence the characters displayed represented some other characters (that might be not obvious to differentiate visually, e.g. control characters are not displayed).

Do you face the same issue when you are using only a plain character-based editor to save your work, please?

Thank you:
Ferenc

Hi Frenec,

I'm not sure I understand what I might have used a text editor to edit.

Hello @meiravR ,

thank you for asking for clarification.

I was just wondering if e.g. between step 3. and 5. you pasted the data somewhere (e.g. to a notebook, an editor, a text file, a chat window, a google doc, an MS Word editor) and then copied it out again?

Thank you:

Hi @Bender,

Nope, copy+pasted it directly to AWS.

Hello @meiravR ,

I have discussed your question internally and it seems to be that the regions are not being listed when the credential you’re using doesn’t have permissions to list the regions.

When you are creating a credential, there’s a checkbox to verify permissions. When enabled it should check the permissions prior to creation and throw errors is perms are missing from the CB policy.

The 504 Gateway Timeout is displayed e.g. when the creation of an environment fails. We are currently working on returning a more meaningful exception (internally tracked DWX-4799).

Kind regards:

Ferenc

Hi @Bender.,

Firstly, setting the this checkbox is not part of the documentation:

Second, after making sure I created a credential with this checkbox enables and creating a policy and a role for them, the problem still happens.

Thank you.

Hello @meiravR ,

thank you for your feedback. I have checked the credentials page and I can see a tooltip on the UI that explains what is the "Enable Permission Verification" for. Although I cannot see the "question mark tooltip" in your screenshot.

Is your AWS environment satisfies the prerequisites detailed here, please?

Thank you:
Ferenc

Hi @Bender,

The quick setup steps in the documentation I linked to go through steps to set up these prerequisites. These steps have been taken by me.
