I was following the steps to pull the pega:latest image from docker hub and run docker container by passing the four JDBC variables, like below -

sudo docker run --name pega8 --publish 32770:5432 -P -e DB_USERNAME=pega -e DB_PASSWORD=pega -e JDBC_URL=jdbc:postgresql://localhost:32770/pega -e JDBC_CLASS=org.postgresql.Driver -d pegasystems/pega:latest

The container started but unable to stat Pega ad Tomcat.
