Host a Ghost 5.0 Blog for Free on Fly.io In 1 Minute — SQLite edition

Host a Ghost Blog Free on Fly.io

Ghost is one of the fastest-growing publishing platforms. However, for those looking to dip their toes in the water, one aspect can be off-putting: the shiny Ghost(Pro) hosting (referral link) starts at $11/month or $108/year — $300/year a year if you want to use your own theme — and even if you self-host on a VPS that will set you back around $5/month or $60 a year. [1]

For years, I have hosted this blog on Heroku’s free tier. It was a bit involved to get set up, and the in-depth tutorial I wrote still gets traffic. However, when Ghost phased out PostgreSQL support, and Heroku changed their free tier, it became much more difficult.[2]

A little while ago, I ran across Fly.io on HackerNews[3]. It looked like it could run Ghost, and has a generous free tier. When it came time to find a better home for my Ghost blogs, I decided to give it a shot. There are several good tutorials out there, and the process only took about half an hour. I was happy. But what if the process took 30 seconds instead of 30 minutes?

Here is a single copy-and-pasteable command[4] that will spin up a fully functional Ghost blog on Fly.io in less than two minutes[5]:

# Prompt for app name
read -p "Enter App Name: " appname </dev/tty && \
# Heredoc wrapper for tidyness (starting now, because we can't seem to prompt for input within heredoc)
bash << EOF
# Uncomment following line for debugging (prints each command before running)
# set -x
# Inspect script first if you are leery of pipe-to-bash
command -v flyctl >/dev/null 2>&1 || { echo >&2 "Fly CLI required and not found. Installing..."; curl -L https://fly.io/install.sh | sh; }
# This will open a browser, where you can enter a username and password, and your credit card (which is required even for free tier, for fraud prevention).
flyctl auth signup
# Create a directory for the project and enter it, since the next command will output a file
mkdir ghost-flyio && cd ghost-flyio
# Create an app -- using Ghost Dockerfile, Seattle region, and app name prompted for earlier -- but don't deploy it
flyctl launch --name $appname --image=ghost:5-alpine --region sea --no-deploy --org personal
# Provision a volume for Ghost's content and SQLite Database. 
# Size can be up to 3GB and still fit in the free plan, but 1GB will be enough for starters.
flyctl volumes create ghost_data --region sea --size 1 -a $appname --auto-confirm
# Install sed (stream editor), if it isn't already installed
command -v sed >/dev/null 2>&1 || { echo >&2 "sed (Stream EDitor) required and not found. Installing..."; sudo apt install sed; }
# Update the port to Ghost's default (2368)
sed -i 's/internal_port = 8080/internal_port = 2368/g' fly.toml
# Append info about where to find the persistent storage to fly.toml
cat >> fly.toml << BLOCK
[mounts]
  source="ghost_data"
  destination="/var/lib/ghost/content"
BLOCK
# Set Ghost url
flyctl secrets set url=https://$appname.fly.dev
# Since we're using SQLite, we need to set ghost to run in development mode
flyctl secrets set -a $appname NODE_ENV=development
# Put the SQLite DB somewhere where it doesn't get overwritten on redeploy...
fly secrets set database__connection__filename=/var/lib/ghost/content/data/ghost-dev.db
# Boom! We're airborne.
flyctl deploy
# End our bash Heredoc
EOF

[Shameless plug] once you have your blog up and running, you might want to grab one of my downright gorgeous[citation needed] Ghost themes: Weblog (premium), MNML (free & open source), Laminim (premium), or Undefined (free & open source).


  1. Assuming you don't already have a VPS with free capacity, and the patience to get Ghost configured alongside whatever else you have on it. (When I had space on an AWS T2 instance I needed for other reasons, I ran a Ghost blog on it using Dokku. It was not worth the hassle. However, Coolify looks like a promising self-hosted Heroku/Netlify alternative.) ↩︎

  2. I’m grandfathered in on the original 750 dyno-hour free tier, which is how I can keep this blog running on Heroku for free. ↩︎

  3. Via their Free Postgres databases for small projects blogpost (HN discussion) ↩︎

  4. Okay, okay, calling it a "single command" is maybe stretching it. ↩︎

  5. If you already have a Fly.io account, you can be done in about thirty seconds — depending on region, current load, and your typing reflexes. ↩︎
