Gitlab self-hosted

It's been a while that I have done trial and error installing Gitlab on my local machine and I find some interesting way of learning.

1st attempt
So first of all, I started to install Gitlab directly using someone's code base from github.

Looks promising, I will give it a try

I don't know what happen when I execute vagrant up but I was astonished

2nd attempt
This time, I read another tutorial with more details and videos
update: 2018-08-07

steps:
sudo apt-get update

sudo apt-get install -y curl openssh-server ca-certificates

sudo apt-get install -y postfix

wget --content-disposition https://packages.gitlab.com/gitlab/gitlab-ce/packages/ubuntu/trusty/gitlab-ce_11.1.4-ce.0_amd64.deb/download.deb

sudo dpkg -i gitlab-ce_11.1.4-ce.0_amd64.deb
sudo gitlab-ctl reconfigure


3rd attempt
This time, is my favorite docker installation. hope everything's okay
