When last looking (around March 2018) at the Bitbucket Server official docker image by Atlassian, as available in Github and Dockerhub, I found little in the way of configuration in support of Data Center.
It now appears as though the configuration has expanded to support deploying this image as a Bitbucket Data Center node.
Is the use of docker containers for deploying Bitbucket DC in production environments supported by Atlassian?
If so, the target platform for the Bitbucket DC containers would be OpenShift/Kubernetes. I came across another question (https://community.atlassian.com/t5/Bitbucket-questions/Bitbucket-Data-Center-on-Kubernetes-Openshift-without-Multicast/qaq-p/934830) which highlighted that 2 customers were having issues with configuring and getting hazelcast to work on Openshift/Kubernetes. Is this possible and also is the use of OpenShift/Kubernetes a supported deployment platform endorsed by Atlassian?
