docker_postgres_init.sql

CREATE USER jira_dbuser WITH PASSWORD 
CREATE DATABASE jira
  WITH
  OWNER = jira_dbuser
  ENCODING = 'UTF8'
  CONNECTION LIMIT = -1;

CREATE DATABASE

dotenv

# Postgresql
PGPASSWORD=myPassword
PGUSER=PGUser
PGDB=database

# Atlassian
TOMCAT_SCHEME=https
TOMCAT_SECURE=true
JVM_MIN=3072m
JVM_MAX=3072m
JVM_HEAP=1024m

Is that jira will intercommunicate with postgres and shall we import the dump from existing database?

conflunce-server spelled wrong it's confluence
and conflunce-server is deprecated, just need to use atlassian/confluence
