Hello everyone, I have a problem, I state I’m a neophyte; I created two docker containers, one for tomcat and one for postgresql. The developers tell me that from jdbc they fail to connect from jdbc included in the tomcat docker container to the postgresql docker container generating this error:
“” org.postgresql.util.PSQLException: The connection attempt failed.
at org.postgresql.core.v3.ConnectionFactoryImpl.openConnectionImpl(ConnectionFactoryImpl.java:315) ~[postgresql-42.2.23.jar:42.2.23] “”
etc … etc …
How can I create a postgresql container to accept connections from jdbc? If I look at the postgresql configuration file I find a * in the network connections section. So this parameter has already been set.
I also know that it’s not up to me but I also wanted to test if everything worked correctly after creating the container; I don’t know how to use jdbc on the net, I can’t find a precise guide. Of course, this thing interests me in relation to me first of all that I can create a postgresql container that accepts all connections.
