sudo docker-compose up -d
# docs say we should run reconfigure at least once
sudo docker exec dockerinfrastructure_gitlab_1 gitlab-cal reconfigure
# lets check everything is working after first up
sudo docker exec dockerinfrastructure_gitlab_1 gitlab-rake gitlab:check SANITIZE=true
# restore backup now
sudo docker cp 1460934678_gitlab_backup.tar dockerinfrastructure_gitlab_1:/var/opt/gitlab/backups
sudo docker exec dockerinfrastructure_gitlab_1 gitlab-ctl stop unicorn
sudo docker exec dockerinfrastructure_gitlab_1 gitlab-ctl stop sidekiq
sudo docker exec dockerinfrastructure_gitlab_1 chmod -R 775 /var/opt/gitlab/backups
# note -it flag so you can respond to questions that restore script asks!
sudo docker exec -it dockerinfrastructure_gitlab_1 gitlab-rake gitlab:backup:restore BACKUP=1460934678
# now lets check again
sudo docker exec dockerinfrastructure_gitlab_1 gitlab-rake gitlab:check SANITIZE=true
# fix all the issues that check reports, for me it was:
