Dokku is an open-source PaaS that allows you to deploy and host multiple applications on a single server. Its functionality is similar to the backend of a service like Heroku, managing tasks such as scaling, load balancing, and database management.
Here's how you can set up Dokku from scratch on AWS:
1. Launch the server
In the AWS control panel, create a new EC2 instance.
- Select Ubuntu 12
- Create a new SSH key pair
- Allow public SSH, HTTP, and HTTPS access to the server
2. Configure DNS
Let's assume your domain is mydomain.com, and you want to host applications as appname.mydomain.com.
In your DNS control panel, create two records:
- A Record pointing @ to the EC2 instance's public IP address
- A Record pointing * to the EC2 instance's public IP address
3. Setup the server
SSH into the EC2 instance and install Dokku:
wget -NP . https://dokku.com/bootstrap.sh
sudo DOKKU_TAG=v0.34.6 bash bootstrap.sh
dokku domains:set-global mydomain.com
cat ~/.ssh/authorized_keys | dokku ssh-keys:add admin
4. Create a test application
On the same EC2 instance, run:
dokku apps:create myapp
sudo dokku plugin:install https://github.com/dokku/dokku-postgres.git
dokku postgres:create railsdatabase
dokku postgres:link railsdatabase ruby-getting-started
5. Set up SSH authentication
On your local machine, add the following to .ssh/config:
Host mydomain.com
HostName mydomain.com
User dokku
IdentityFile ~/ServerKey.pem
6. Deploy a test application
Then, on your local machine, run these commands to deploy a test application:
git clone https://github.com/heroku/ruby-getting-started
cd ruby-getting-started
git remote add dokku dokku@example.com:myapp
git push
