How to create a bash script file in Docker? - bash

Question

I wrote a script that the task is to create a text file and write into two lines.
This has been done, but more than once and I do not understand why because the script file does not contain any cycle and once the file is executed.
#!/bin/bash
<other, non-relevant variables and commands>
PHP_ROOT_DIR=/etc/php-5.6.22
PHP_CGI_WRAPPER=php-5622
mkdir -p $(dirname $0)/cgi-bin
touch $(dirname $0)/cgi-bin/$PHP_CGI_WRAPPER
echo -e "#!/bin/bash" >> $(dirname $0)/cgi-bin/$PHP_CGI_WRAPPER
echo -e "exec ${PHP_ROOT_DIR}/bin/php-cgi" >> $(dirname $0)/cgi-bin/$PHP_CGI_WRAPPER
<other, non-relevant variables and commands>
exit 0
output file content:
#!/bin/bash
exec /etc/php-5.6.22/bin/php-cgi
#!/bin/bash
exec /etc/php-5.6.22/bin/php-cgi
#!/bin/bash
exec /etc/php-5.6.22/bin/php-cgi
Update:
This result occurs when run Docker container.
If I reduce my script to only of above part (removed non-relevant code parts), then working correctly on host OS and Docker in a container equally.
But the problem is still not fixed.
full version script file is this:
#!/bin/bash
source $(dirname $0)/create_vhost_config.sh
source $(dirname $0)/create_sample_html.sh
IP=$(ip route get 1 | awk '{print $NF;exit}')

Change this:
echo -e "#!/bin/bash" >> $(dirname $0)/cgi-bin/$PHP_CGI_WRAPPER
to this:
echo -e "#!/bin/bash" > $(dirname $0)/cgi-bin/$PHP_CGI_WRAPPER
