I used this bamboo environment bamboo_deploy_version_previous in a rollback task.
I have a deploy task called deploy2prod, for example, currently it is release-22
It will rename the old containers to <projectId>-release-21 first, then deploy a new service. release-21 is the release number of previous deployment.
I added another rollback task after prod release. Will only start it if required.
I still use bamboo_deploy_version_previous as variable to get the name of <projectId>-release-21, but I found this rollback task is failed. It always tries to get the current release number <projectId>-release-22
Seems a bug for me, need confirm with Bamboo develop team.
### Updates
In bamboo logs, deployment task deploy2prod, bamboo_deploy_version_previous and bamboo_deploy_version are diffrerent:
amboo_deploy_version_previous=release-21
bamboo_deploy_version=release-22
But in rollback task, both bamboo_deploy_version_previous and bamboo_deploy_version are same
bamboo_deploy_version_previous=release-22
bamboo_deploy_version=release-22
