The health-cmd in these files is obsolete. Since containers are now from scratch, there is no /bin/sh, and the check won't execute, since it is in shell form, not exec array. However, images have health command already defined, so probably we could skip that at all. https://github.com/codenotary/immudb-py/blob/master/tests/starttestcontainers.sh
