If you are using jenkins image from dockerhub repo and create a container then you can get the initial password using:

$ sudo docker exec jenkins_containerid cat /var/lib/jenkins/secrets/initialAdminPassword

OR if installing from jenkins.io docs (https://jenkins.io/doc/book/installing/):

$ sudo docker exec jenkins_containerid cat /var/jenkins_home/secrets/initialAdminPassword

OR you can see the docker logs of container

$ sudo docker logs jenkinscontainerID
