Dockerized gitlab upgrade (from 8.4.4-ee.0 to 8.8.1-ee.0) and reconfigure ISSUE "INFO: Port 8889 in use: Address already in use - bind(2) for 127.0.0.1:8889"

How to Use GitLab Upgrade
1

Overview: We dockerized our gitlab.
–Initially we dockerized our gitlab with “gitlab/gitlab-ee:8.4.4-ee.0” version.
–restore 8.4.4-ee non-dockerized gitlab version backup into our dockerized gitlab-ee:8.4.4-ee.0
Our goal is upgrade dockerized gitlab from 8.4.4-ee.0 to 8.8.1-ee.0 with existing repository (data). We performed below steps through ansible playbook and it given ‘gitlab-ctl reconfigure’ error “INFO: Port 8889 in use: Address already in use - bind(2) for 127.0.0.1:8889”.

steps performed during upgrade.

  1. docker pull gitlab/gitlab-ee:8.8.1-ee.0
  2. docker stop docker ps -a | grep gitlab | awk '{print $1}'
  3. docker rm docker ps -a | grep gitlab | awk '{print $1}'
  4. remove existing gitlab docker image.
    • name: Start gitlab
      shell: docker run --detach
      –hostname gitlab.example.com
      –publish 443:443 --publish 80:80
      –name gitlab
      –restart always
      –volume /srv/gitlab/config:/etc/gitlab:Z
      –volume /srv/gitlab/logs:/var/log/gitlab:Z
      –volume /opt/gitlabData:/var/opt/gitlab:Z
      gitlab/gitlab-ee:8.8.1-ee.0
  6. configure LDAP
  7. docker exec gitlab gitlab-ctl reconfigure

Step#7 (gitlab-ctl reconfigure) given below error.
