I’m stuck trying to get n8n up and running on Heroku using Docker. I’ve set up a Postgres database and created the necessary files, but something’s not clicking. Here’s what I’ve done so far:
Set up Postgres 11:
heroku addons:create heroku-postgresql:hobby-dev --version=11 -a my-application
Created a simple Dockerfile:
FROM n8nio/n8n
Made a heroku.yml file with config settings and build instructions.
When I check the logs, I see warnings about Tini not running as PID 1 and some permission issues. The app keeps crashing with an H10 error.
Has anyone successfully deployed n8n on Heroku? What am I missing here? Any tips or tricks would be super helpful. I’m pretty new to this, so I might be overlooking something obvious. Thanks in advance for any help!
I’ve been down this road before, and it can be tricky. One thing that helped me was tweaking the Dockerfile. Instead of just using the base n8n image, try something like this:
FROM n8nio/n8n
USER root
RUN apt-get update && apt-get install -y postgresql-client
USER node
This gives you more control over the environment. Also, make sure your DATABASE_URL in Heroku’s config vars is correct. It should look something like:
postgres://username:password@host:5432/database
Don’t forget to set N8N_ENCRYPTION_KEY too - it’s crucial for data security.
Lastly, if you’re still hitting walls, consider using the Heroku CLI for debugging. Run ‘heroku logs --tail’ to see real-time logs. It’s been a lifesaver for me in pinpointing exact issues.
hey sofiag, i’ve had similar issues. try using the official n8n heroku button instead of setting it up manually. it handles most of the config for you. if you still wanna DIY, check your env variables - make sure DATABASE_URL is set correctly. also, try running n8n with --tunnel flag for debugging. good luck!
I’ve encountered similar challenges deploying n8n on Heroku. One often overlooked aspect is the Procfile configuration. Ensure you have a Procfile in your project root with the following content:
web: n8n start
This tells Heroku how to run your application. Also, double-check your environment variables, particularly N8N_PROTOCOL and N8N_HOST. They should be set to ‘https’ and your Heroku app’s domain, respectively.
If issues persist, consider using the n8n-heroku buildpack instead of Docker. It’s designed specifically for Heroku deployments and might resolve your current complications.
