Error When Creating New Compute Group

Datomic Cloud
1

Greetings. I am looking to add a new compute group to an existing Datomic Cloud setup. Following the directions here:

https://docs.datomic.com/cloud/operation/compute-template.html#parameters

Using the current newest template:
https://s3.amazonaws.com/datomic-cloud-1/cft/936-9118/datomic-query-group-936-9118.json

I get the following error from CloudFormation:

No export named pnx-ions-VpcLinkId found. Rollback requested by user.

And the stack is RolledBack. (e.g. fails to deploy, since it is a new stack)

Please advise. Thanks!

Hi @lucasjordan

What version is the “existing Datomic Cloud Setup” and what topology is it? I ask because I suspect you are encountering an issue launching the latest version which is now on a single topology against a version older than 884-9095 which was the critical release where we removed the separate topologies.

https://docs.datomic.com/cloud/changes.html#884-9095

If that is the case, you will also need to upgrade your storage CFT.

My plan was to use a group named “pnx-ions-primary” as the primary, and then create additional compute groups for “Environments” prod, dev, etc.

pnx-api % datomic system list-instances pnx-ions -r us-east-1 -p PNX
WARNING: Use of -A with clojure.main is deprecated, use -M instead
[{“group-name”:“pnx-ions-primary”,
“group-cft-version”:“781”,
“group-cloud-version”:“9041”,
“instance-id”:“i-0d8da1251f2de90bb”,
“status”:“running”},
{“group-name”:“pnx-ions-primary”,
“group-cft-version”:“781”,
“group-cloud-version”:“9041”,
“instance-id”:“i-052551e259dfd4244”,
“status”:“running”},
{“group-name”:“access-gateway”,
“group-cft-version”:“781”,
“group-cloud-version”:“9041”,
“instance-id”:“i-0a4be6b727dad60a5”,
“status”:“running”},
{“group-name”:“pnx-api-dev”,
“group-cft-version”:“781”,
“group-cloud-version”:“9041”,
“instance-id”:“i-0a08ac47e640c7b5c”,
“status”:“running”}]

I am assuming 884-9095 is [cft]-[cloud] for version scheme. So I need to update “pnx-ions-primary” and before I can add a new group? (and update “pnx-api-dev” while I am at it)

Thanks for confirming.

@lucasjordan yes, you will need to upgrade your primary to at least 884-9095 (although I recommend moving everything to the latest) before adding additional new (post 884) compute groups.
