Why Install Ghost On Dokku?

Despite Dokku being my most preferred setup choice, it may not be the most ideal option for multiple Ghost installations, as it does not offer the full range of customisations available to Ghost, as well as the ease of Ghost management through Ghost-CLI, as these are critical criteria for me.

However, if customisation or full management controls of Ghost does not matter to you at all, this "Ghost Docker Image on Dokku", may be a viable option for you.

Nonetheless, this option does offer me the significant ability to use Dokku, where besides being able to install Ghost, I can also choose to install other self-built webapps, in the near-to-long-term, that will run easily from the same Dokku server.


If this doesn't represent your choice of setting up multiple Ghost-installs on ONE Server, you should check out this article I wrote about the other option(s) that are available to you.


Benefits

  • Monthly Cost-Savings—Save on additional costs running multiple servers. However, if you do expect high-traffic to your website, then please skip this guide entirely. You will be better off tapping on a Ghost(PRO) Subscription.
  • Dokku: Heroku Commands—Having the ability to easily run git-like commands to push code updates to Dokku server and automate processing to compile and publish code to production.
  • Dokku: Flexible Extensibility—Able to handle not just multiple instances of Ghost but even other webapps setups like WordPress / ReactJS / AngularJS / Ruby / Go / or any other setups.
  • Dokku: Powerful WebApps Management Platform—Use one SSH login to manage all webapps, in place of multiple, confusing connections to multiple servers to handle multiple maintenances of multiple webapps like Ghost.

Limitations

  • Very Tedious To Setup—Will require significant Technical knowhow, persistency and lots of patience! This is quite true given the need to understand a little of both Dokku & Docker environments, on top of Ghost.
  • No Ghost Control Thru Ghost-CLI—Having Ghost-CLI  would have been very useful as it allows each individual Ghost instance to be easily managed, upgraded or uninstalled where necessary. Too bad, it isn't available on a Ghost Docker Image installation.
  • No Customisation Where Needed—Sadly, this option is a critical-killer for me, as a Ghost Docker Image is non-editable, which totally killed off the idea for customisations per Ghost instance, such as implementing a Custom Storage Adapter where needed.—Local storage data is slightly hard to access but the good thing is that it is held privately within your Dokku server.
  • Limited Ghost Installs On 1GB-Memory Server—DigitalOcean Baseline 1GB-Memory (USD5.00) Server might only be able to handle a maximum of 2x Ghost installations at one time. I have been testing the server for >1 month and do frequently experience Request Timeout Errors, where either (a) Ghost lost connection with Server due to maxed out memory usage, or (b) Ghost is unable to automatically-save the work I've typed, or (c) Ghost faced the occasional problem of uploading multiple images at once or large images that are >1MB.

    The solution is to do a Forced Power Cycle process via Droplet > Power > Power Cycle.

    This issue can also be easily mitigated by upgrading to a server configuration that has significantly more memory, which does add more to your monthly costs.

Caveat

This setup requires Significant technical-knowhow on how to use the following toolset:

  • Terminal (macOS) or Command Prompt (Windows),
  • Command Line Interface (CLI),
  • GitHub, and
  • Dokku (Smallest PaaS)

However, this guide is designed to be "Intermediate-friendly", and should not pose as a challenge to many as long as you are willing to try. ✌🏻
