Hello,
Is there a way to disable tentacle icons with yellow screens displaying under environments when tentacle is not running latest version?
We keep upgrading Calamari during deployments, but do not want to do client upgrades unless it becomes absolutely necessary therefore I’d like to make icons appears as everything is normal.
Hi Lucas,
Thanks for getting in touch! Yes this can be done. Each Tentacle has the ability to be locked from inside the environments page. The following blog post has some further information on this.
Hope that helps. 
Best regards,
Daniel
OK, I should have asked right away so I apologize for not being clear.
How can I do it for couple hundred endpoints? Is there a supported way to automate it? No one will be able to go through this via console one by one in large environments.
Hi Lucas,
Thanks for getting back. Unfortunately this is not something that can be done via the UI. It will need to be scripted via API. For some examples and documentation regarding our API, see the following link: https://github.com/OctopusDeploy/OctopusDeploy-Api
Let me know if you have any questions here.
Best regards,
Daniel
