+# Dokku
+
+[Dokku](http://dokku.viewdocs.io/dokku/) is an open-source Heroku-like, that helps you manage and deploy web applications.
+
+## Installation
+
+As of debian user we can install with apt
+
+```
+# install prerequisites
+sudo apt update -qq >/dev/null
+sudo apt install -qq -y apt-transport-https
+
+# install docker
+wget -nv -O - https://get.docker.com/ | sh
+
+# install dokku
+wget -nv -O - https://packagecloud.io/dokku/dokku/gpgkey | sudo apt-key add -
+OS_ID="$(lsb_release -cs 2>/dev/null || echo "bionic")"
+echo "xenial bionic focal" | grep -q "$OS_ID" || OS_ID="bionic"
+echo "deb https://packagecloud.io/dokku/dokku/ubuntu/ ${OS_ID} main" | sudo tee /etc/apt/sources.list.d/dokku.list
+sudo apt update -qq >/dev/null
+sudo apt install -qq -y dokku
+sudo dokku plugin:install-dependencies --core
+```
+
+When asked, you can accept web page front end installation.
+
+### Configure your host
+
+If you are using a domain provider, make sure to create an A record in your DNS table,
+pointing to your server's Ip.
+
+If you are deploying dokker on your local machine (for testing purpose), you will need to modify `/etc/hosts` AND use `dnsmasq` ( Replace `<dokku.local>` by the domain name of your choice).  
+
+1. modify first line of `/etc/hosts` :   
+    ```
+    127.0.0.1   localhost   <dokku.local>
+    ```   
+2. `sudo apt install dnsmasq`  
+3. `sudo systemctl enable dnsmasq`  
+4. Add `address=/<dokku.local>/127.0.0.1` in `/etc/dnsmasq.conf` 
+5. Reboot your computer
+
+
+### Configure ssh
+
+Configure a public/private key pair for ssh root access.  
+Run following commands as root:  
+1. As root, run `ssh-keygen`  
+2. Copy the key to authorized keys for dokku:  
+    ```
+    cat ~/.ssh/id_rsa.pub  |sshcommand acl-add dokku superuser
+    ```  
+3. In setup webpage at `http://<dokku.local>`, paste content from  `/root/.ssh/id_rsa.pub` (only the part with `ssh-rsa`).

+dokku postgres:create djangodatabase
