arcas file is empty?

[carlosonunez-vmw]

Reference Architecture: TKO on vSphere backed by VDS

What Happened?

I tried to run the command described in the README:

arcas --env vsphere --file /tmp/arcas.json --avi_configuration --tkg_mgmt_configuration --shared_service_configuration --workload_preconfig --workload_deploy --deploy_extentions

but it does nothing because the arcas tool that the command above is using is an empty file:

root@photon-machine [ ~ ]# file $(which arcas)
/usr/bin/arcas: empty

What Was Expected?

For something to happen

How to Reproduce

1. Create an Arcas appliance from the OVA
2. SSH in
3. Run file $(which arcas)

Versions

Version: 1.2.0.50
Build: 19794220

@carlosonunez-vmw Could you please confirm if you generated the json file for your environment using the steps mentioned in the document - https://github.com/vmware-tanzu/service-installer-for-vmware-tanzu/blob/main/docs/product/release/vSphere%20-%20Backed%20by%20VDS/TKGm/TKOonVsphereVDStkg.md (Step 4 in "Deploy Tanzu for Kubernetes Operations" section) ?

SIVT User Interface saves the json file to "/opt/vmware/arcas/src/vsphere-dvs-tkgm.json" location [OR] if you have created this file manually, you need to copy it SIVT and provide the path in above command you have mentioned.

Hope this helped, let me know if you have further queries.

i created the file using the template on the page locally inside of the appliance.

Could you please cross check the name of the file you created ?

Looks like it was not saved with "arcas.json" file name.

[carlosonunez-vmw]

But the issue is that the "arcas" binary itself is empty.

yes, SIVT OVA doesn't have arcas binary. arcas is running as service in SIVT OVA and we have followed CLI based automation.

You can refer /opt/vmware/arcas/src/cli.py file for more details.

[carlosonunez-vmw]

That's confusing. Step 4 of the instructions states to use arca. Is this out of date?

@carlosonunez-vmw "arcas" is a service running inside the SIVT OVA. You can type "arcas --help" command to get more idea on the available flags.
For starters, "arcas --env <vsphere/vcf/vmc> --file complete-path-to-the-input-json-file" are the mandatory flags to be provided by the user. We also have a UI that can help in generation of the input file.

To check the status of arcas service, you can run "systemctl status arcas.service" on your SIVT ova.
We can connect offline if you need more clarity on the design of the product.

It seems like there might be some confusion around what I'm reporting. Here's a GIF that explains what I'm running into.

TL;DR: Service Installer guides state to use arcas after the JSON has been created, but the arcas file is empty.

I was able to work around this by doing the below from inside of the SIVT:

pip install /opt/vmware/arcas

However, the documentation suggests that the arcas pip should be installed once the appliance has been deployed. Given this, I'm going to leave this issue open.

This issue is addressed in SIVT 2.0 release. Closing the issue.
