There is next documention by link:
Builds and deployments are normally run on the Bamboo agent’s native operating system. However, both jobs and environments can be instrumented to be run in a Docker container, for better control over the available tool set and additional build isolation. Docker is a tool which automates the running and deployment of applications inside containers.
The Docker image can be configured on a plan level and on the job level. The configuration from the job level overrides the Docker settings from plan level.
Anybody got it work or there is a bug ?
PS: colleagues asked the same question here.
