Gitlab Installation : The Best way

by

In this lab, we will get our hands dirty with a versatile method for GitLab installation that transcends OS dependencies. Explore how we leverage the power of Docker Engine in the below lab to achieve this streamlined and efficient setup.

The prerequisites will be the same. check previous Gitlab installation post

create a directory and start the docker service

root@TzoneLabs:~# mkdir -p /data/gitlab/ssl
root@TzoneLabs:~# systemctl start docker.service                                     ## docker should install on server

put your domain certificate and key 

root@TzoneLabs:~# cd /data/gitlab/ssl
root@TzoneLabs:/data/gitlab/ssl# ls
my_domain.crt  my_domain.key
root@TzoneLabs:/data/gitlab/ssl#

Install GitLab using Docker Engine

Run the below command to create and start the container.

docker run --dt \
  -h gitlab.tzonelabs.com \
  -p 443:443 -p 80:80 -p 22:22 \
  --name gitlab \
  --restart always \
  -v /data/gitlab/config:/etc/gitlab:Z \
  -v /data/gitlab/logs:/var/log/gitlab:Z \
  -v /data/gitlab/data:/var/opt/gitlab:Z \
  --shm-size 256m \
  --env GITLAB_OMNIBUS_CONFIG="external_url 'https://gitlab.tzonelabs.com/';" \
  --env nginx['ssl_certificate']="/data/gitlab/ssl/domain.crt" \
  --env nginx['ssl_certificate_key']="/data/gitlab/ssl/domain.key" \  
  gitlab/gitlab-ce:latest

same command in one line–

root@TzoneLabs:~# docker run -d -h gitlab.tzonelabs.com -p 443:443 -p 80:80 -p 22:22 --name gitlab --restart always -v /data/gitlab/config:/etc/gitlab:Z -v /data/gitlab/logs:/var/log/gitlab:Z -v /data/gitlab/data:/var/opt/gitlab:Z --shm-size 256m --env GITLAB_OMNIBUS_CONFIG="external_url 'https://gitlab.tzonelabs.com/';" --env nginx['ssl_certificate']="/data/gitlab/ssl/domain.crt" --env nginx['ssl_certificate_key']="/data/gitlab/ssl/domain.key" gitlab/gitlab-ce:latest

once your container run your GitLab config file will be on the below location

root@TzoneLabs:~# cd /data/gitlab/config
root@TzoneLabs:~# vim gitlab.rb

if you have changed any parameter in gitlab.rb file then you have to reconfigure GitLab using the below command to new changes take place.

Cross-check changes inside containers and run the below commands.

root@TzoneLabs:~# docker exec -it gitlab bash
gitlab-ctl reconfigure          ## inside the gitlab container

How to back up your GitLab and restore.

if your GitLab is running on the server without a docker

create backup

root@TzoneLabs:~# gitlab-backup create

## Note -- the Default path of gitlab backup is /var/opt/gitlab/backups/

restore backup

## Note -- copy backup to directory /var/opt/gitlab/backups

root@TzoneLabs:~# gitlab-backup restore

if your GitLab is running on the docker

create backup

root@TzoneLabs:~# docker exec -t <container name> gitlab-backup create

## Note -- the Default path of gitlab backup is /var/opt/gitlab/backups/

restore backup

## Note -- copy backup to directory /var/opt/gitlab/backups

root@TzoneLabs:~# docker exec -t <container name> gitlab-backup restore
