I am fresh for docker and kong .

I have 2 ECS instances just call them “A” and “B” ;  
I install docker and build kong 1.3 on “A” ;  
The “B” has a postgressql ;  
The I try to migrations kong on “A” linking to postgresql on “B”, like:

docker run --rm   
-e “KONG\_DATABASE=postgres”   
-e “KONG\_PG\_HOST=10.47.136.45”   
-e “KONG\_PG\_PORT=6506”   
-e “KONG\_PG\_DATABASE=devauth”   
-e “KONG\_PG\_USER=devauthdata”   
-e “KONG\_PG\_PASSWORD=Paic1234#”   
ay/kong:1.3 kong migrations bootstrap

it failed :  
Error: [PostgreSQL error] failed to retrieve server\_version\_num: FATAL: password authentication failed for user “devauthdata”

but the username and password are valid ！！！

I think I know that:  
it is Special characters !  
the password contains a “#” !  
I just try a new password without “#” , it success !!!  
so, is the way for kong to link postgresql-11 wrong???  
or need some improvement？
