I'm thinking about the way Accounts work. You could add users to the account, but their usernames would have to be unique. So an existing user would need another (different) username in the service account.
We're doing work on projects, where users (not accounts) can be members and have different roles in different projects. It may be possible to have a service 'project' with already existing users, but I've not tried it. paul.an...@shapeblue.com www.shapeblue.com 3 London Bridge Street, 3rd floor, News Building, London SE1 9SGUK @shapeblue -----Original Message----- From: Sven Vogel <s.vo...@ewerk.com> Sent: 13 October 2020 12:06 To: dev@cloudstack.apache.org Subject: Re: [DISCUSS] CloudStack Kubernetes Cluster Auto-Scaler support Should it possible to grant other users the control about the service user? __ Sven Vogel Lead Cloud Solution Architect EWERK DIGITAL GmbH Brühl 24, D-04109 Leipzig P +49 341 42649 - 99 F +49 341 42649 - 98 s.vo...@ewerk.com www.ewerk.com Geschäftsführer: Dr. Erik Wende, Hendrik Schubert, Tassilo Möschke Registergericht: Leipzig HRB 9065 Support: +49 341 42649 555 Zertifiziert nach: ISO/IEC 27001:2013 DIN EN ISO 9001:2015 DIN ISO/IEC 20000-1:2011 ISAE 3402 Typ II Assessed EWERK-Blog<https://blog.ewerk.com/> | LinkedIn<https://www.linkedin.com/company/ewerk-group> | Xing<https://www.xing.com/company/ewerk> | Twitter<https://twitter.com/EWERK_Group> | Facebook<https://de-de.facebook.com/EWERK.IT/> Auskünfte und Angebote per Mail sind freibleibend und unverbindlich.

Ultimately it has to be on the user to control 'who' can do what. paul.an...@shapeblue.com www.shapeblue.com<http://www.shapeblue.com> 3 London Bridge Street, 3rd floor, News Building, London SE1 9SGUK @shapeblue -----Original Message----- From: David Jumani <david.jum...@shapeblue.com> Sent: 13 October 2020 11:39 To: dev@cloudstack.apache.org Subject: Re: [DISCUSS] CloudStack Kubernetes Cluster Auto-Scaler support Thanks Daan. Users within the same account can alter the cluster, so I'm thinking of a service user within the same account and use the service user's keys. This will also prevent any mess up if the user provides his keys and then later regenerates them. ________________________________ From: Daan Hoogland <daan.hoogl...@gmail.com> Sent: Tuesday, October 13, 2020 3:28 PM To: dev <dev@cloudstack.apache.org> Subject: Re: [DISCUSS] CloudStack Kubernetes Cluster Auto-Scaler support That is a good question. Is the user going to be the only user responsible for messing up the k8 cluster, or will other users be able to as well? For convenience and if audit is to not lay false balme on a user, I'd say create a system/service account, if several users can mess up each other with it... makes sense?
