I found an error on my testing environment, using the image built from master branch.
On line 4 of run.sh it compares INIT_BACKUP with a numeric value, so starting image without setting INIT_BACKUP raises the following error
/run.sh: line 4: [: : integer expression expected
Fixed setting a default value into run.sh for INIT_BACKUP variable on line 4
