Heroku and free plan
In a blog post published at August 25, 2022 , Heroku general manager stated that they will stop offering free dynos dyno is heroku computing unit
starting November, 28 2022, check the blog post and Remove free products plan
This decision will affect solo developers who use heroku to te st their ideas or host projects at early stage, and regarding to how easy it is to use heroku now we need an alternative
Dokku
what is dokku ?
An open source PAAS alternative to Heroku.
Dokku helps you build and manage the lifecycle of applications from building to scaling.
Dokku is an extensible, open source Platform as a Service that runs on a single server of your choice. Dokku supports building apps on the fly from a git push via either Dockerfile or by auto-detecting the language with Buildpacks, and then starts containers based on your built image. Using technologies such as nginx and cron, Web processes are automatically routed to, while background processes and automated cron tasks are also managed by Dokku.
Getting started
Minimum requirement to run dokku are:
- A fresh installation of
Ubuntu 18.04/20.04/22.04
orDebian 10+ x64
. - At least 1 GB of system memory.
- Attaching at least one domain name to your server ip, say
example.com
.
Installation
- First ssh into your remote server.
- Download the
bootstrap.sh
installation script
wget https://raw.githubusercontent.com/dokku/dokku/v0.28.1/bootstrap.sh
- Run the installer script by prefixing with
DOKKU_TaG=xxx
env variable to specify which version you want, latest is better offcourse
sudo DOKKU_TAG=v0.28.1 bash bootstrap.sh
This command will automatically use
apt
to update and install dependecies such as docker, then it will created the required containers, also a new userdokku
will be createdNext step is to add your public ssh key to be able to run dokku commands remotly, because dokku doesn't have a cli to install on your local machine like
heroku toolbel
To add your key, get the content from your local machine, the key filename usually called id_rsa.pub
cat ~/.ssh/id_rsa.pub
copy the file content and then on the remote server run this last command
echo "your-public-key-contents-here" | dokku ssh-keys:add admin
once this is done, you can execute dokku
commands remotly from your locall machine like this
ssh dokku@example.com apps:List
ssh dokku@example.com domains:report --global
- Now we need set the domain as a dokku global domain.
ssh dokku@example.com domains:add-global example.com
# check your setup
ssh dokku@example.com domains:report --global
=====> Global domains information
Domains global enabled: true
Domains global vhosts: example.com
with this done, any app you deploy will be available at app-name.example.com
by default unless you add another domain specific to the app
now you can create a new empty app like this
# From remote server shell
dokku apps:create my-first-application
# From your local machine
ssh dokku@<domain> apps:create my-second-app
In the next article i will show you how to deploy a NextJS application to your server
