Initiall my interest to that problem was caused by the bug [1] due to whose once environment was deployed with failure it stays forever with that status even if it have been deployed sucessfully later.
For now status determination happens in three stages: - If at least one of all sessions of env, regardless of version, is in DEPLOYING/DELETING or DEPLOY_FAILURE/DELETE_FAILURE states - state of that session taken as state of environment. Sessions prioritized by version and midification date. - If there is no such sessions, but at least one is in OPENED state - environment state will be PENDING. - Otherwise environment will have READY status. Accordingly to that - once session was deployed with failure - it stays in that status even if it was deployed successfully later. In UI statuses are taken directly from API except another "calculated" status NEW. Environment matches status NEW if it has version = 0 and it has apps with status 'pending' [2]. After discussion inside Mirantis Murano team we came to these thoughts: - We need to remove statuses that does not related to deployment (PENDING). - Introduce NEVER_DEPLOYED (or NEW) status. - Change READY to DEPLOYED. - Possibly we need to keep state in Environment table in DB and no calculate it queriyng session every time. PENDING status was needed to indicate that another user do something with the environment. But it was decided, that this information must be placed somwhere else, to not be in coflict with deployment status. Another proposal was to additionaly show if environment has some "dirty"/not-deployed changes in it. First of all let's discuss quick fix of the alghorithm of Environment status matching [3]. I propose to take status of last modified session as status of an environment. At second let's discuss overall situation and more extensive changes that we might want introduce.
