What version of ansible are you running?
According to the doc strings in the docker.py module:
volumes:
description:
- List of volumes to mount within the container
- 'Use docker CLI-style syntax: C(/host:/container[:mode])’
- You can specify a read mode for the mount with either C(ro) or C(rw).
Starting at version 2.1, SELinux hosts can
additionally use C(z) or C(Z) mount options to use a shared or
private label for the volume.
If I'm understanding the above correctly, options z and Z became available
for SE Linux hosts in Ansible 2.1.
Also, I wonder if the format of ` - /mydata/folder:/opt/mydata/:Z` might be
incorrect? I would remove the last '/', changing it to ` -
/mydata/folder:/opt/mydata:Z`
