 This is merely a collected records of my experience to setup DevOps infrastructure with Gitlab, Gitlab-CI, and Dokku.
-Our setup uses virtual environment which is run on Proxmox VE with LXC as OS-level virtualization. The first thing to do is setup the virtual server through web-based management of Proxmox VE. We just need 2 virtual servers, one for Gitlab/Gitlab-CI and one for Dokku. We allocate one CPU and 2048 MB of RAM for each virtual server.

-There are steps for doing setup of virtual server and thankfully it is provided as wizard. Our steps are described below.
+There are steps for doing setup of virtual server and thankfully these are provided as a wizard in Proxmox VE. For LXC, our steps are described below.
   - Login to the web-based management of Proxmox VE.
   - Select Templates-"ubuntu-14.04_standard*", and click Download.
-  - Create CT.
+  - Create a container (CT).
   - Set Hostname and Password.
   - Use the template image: ubuntu 14.04 standard.
   - Set disk size from local storage: 8 GB.
   - Set network configuration, IPv4 Static with netmask /21, and set the gateway.
-  - Set DNS domain
+  - Set servers for DNS domain.
   - Finish the wizard.
 ===== Gitlab =====
-  - Using Console on web-based management of Proxmox VE, type these commands and follow the needed steps.<code># adduser stwn
+  - Use Console on web-based management of Proxmox VE, type these commands and follow the needed steps.<code># adduser stwn
 # visudo</code>
   - Close the Console and use terminal emulator in your computer.
   - Remote login to the Gitlab server with SSH. <code>$ ssh stwn@gitlab-server</code>
   - Update the packages index. <code>$ sudo apt-get update</code>
-  - Install curl and screen. <code>$ sudo apt-get install curl screen</code>
+  - Install curl and screen packages. <code>$ sudo apt-get install curl screen</code>
   - Run this command. Adapt the version to the recent version of Gitlab. <code>$ curl -LJO https://packages.gitlab.com/gitlab/gitlab-ce/packages/ubuntu/trusty/gitlab-ce_8.6.6-ce.0_amd64.deb/download</code>
   - Install the downloaded Gitlab package. <code>$ sudo dpkg -i gitlab-ce_8.6.6-ce.0_amd64.deb</code>
   - Reconfigure Gitlab for the first time. <code>sudo gitlab-ctl reconfigure</code>
-  - Configure Gitlab. <code>$ sudo nano /etc/gitlab/gitlab.rb</code>Uncomment these lines.<code>web_server['external_users'] = []
+  - Configure nginx-related options. <code>$ sudo nano /etc/gitlab/gitlab.rb</code>Uncomment these lines.<code>web_server['external_users'] = []
 web_server['username'] = 'gitlab-www'
 web_server['group'] = 'gitlab-www'</code>
-  - Restart Gitlab. <code>$ sudo gitlab-ctl restart</code>Use this command to see the log of Gitlab. <code>$ sudo gitlab-ctl tail</code>
+  - Reconfigure and restart Gitlab. <code>$ sudo gitlab-ctl reconfigure
+$ sudo gitlab-ctl restart</code>Use this command to see the log of Gitlab. <code>$ sudo gitlab-ctl tail</code>
 ===== Gitlab-CI =====
 ===== Dokku =====
+  - Download ISO image of Ubuntu 14.04.4, and put it in a place which is accesible by Proxmox VE. Boot the virtual machine through the web-based management and follow the steps of the Ubuntu installer.
+  - Login to the Console of the web-based management or via SSH from your local computer/laptop. Configure the interface of the Dokku server. <code>$ sudo nano /etc/network/interfaces</code>Put these lines in that file.<code>iface eth0 inet static
+      address 10.16.7.128
+      netmask 255.255.248.0
+      gateway 10.16.7.1
+      dns-nameservers 10.16.7.1</code>
+  - Edit the sources.list file to configure the packages repository server. <code>$ sudo nano /etc/apt/sources.list</code>
+  - Update packages list and upgrade all packages. <code>$ sudo apt-get update
+$ sudo apt-get upgrade</code>
+  - After that, upgrade the distribution. <code>$ sudo apt-get dist-upgrade</code>
+  - Download bootstrap.sh script from Dokku repository. <code>$ wget https://raw.githubusercontent.com/dokku/dokku/v0.5.5/bootstrap.sh</code>
+  - Run the script. <code>$ sudo DOKKU_TAG=v0.5.5 bash bootstrap.sh</code>We need to relax waiting for this command to complete. It depends on the Internet connection. Please watch the network status of the server, if it has on going/active traffic then the script must be working and we should be sit back while it really accomplishes its mission :D
+  - Setup SSH key pairs. Get the public key from Gitlab server with our user in it, e.g. stwn. These commands should be run on the Gitlab server.<code>$ ssh-keygen -t rsa
+$ cat .ssh/id_rsa.pub</code>
+  - Visit the local web configuration of Dokku in http://dokku.server/ and copy the content of the output of the previous last command to the Public Key section.
