$docker logs db-1

chown: changing ownership of '/proc/1/fd/1': Permission denied
chown: changing ownership of '/proc/1/fd/2': Permission denied
about to fork child process, waiting until server is ready for connections.
forked process: 19
ERROR: child process failed, exited with error number 1
chown: changing ownership of '/proc/1/fd/1': Permission denied
chown: changing ownership of '/proc/1/fd/2': Permission denied
about to fork child process, waiting until server is ready for connections.
forked process: 18
ERROR: child process failed, exited with error number 1
