Setup Problems with Workflow Tool on Cloud Platform
I am trying to get a workflow automation tool running on a cloud hosting service using Docker containers. The deployment keeps failing and I can’t identify the root cause.
Database Setup Command:
heroku addons:create heroku-postgresql:hobby-dev --version=11 -a workflow-app
2020-04-15T11:19:50.178271+00:00 app[web.1]: [WARN tini (3)] Process management issue detected
2020-04-15T11:19:50.179480+00:00 app[web.1]: su-exec: setgroups: Operation not permitted
2020-04-15T11:24:54.478493+00:00 heroku[router]: at=error code=H10 desc="App crashed"
The application crashes immediately after startup. Has anyone successfully deployed this type of workflow tool on Heroku before? What configuration changes might resolve these permission and process management errors?
This is a Heroku security model vs n8n container setup issue. Hit this same problem 8 months ago migrating our workflows. The tini warning plus setgroups error means you’re running into Heroku’s user privilege restrictions - you can’t run processes as different users in their dyno environment. Your PostgreSQL config is wrong. Don’t use localhost for POSTGRES_HOST on Heroku. The managed PostgreSQL addon gives you connection details through DATABASE_URL that gets auto-injected. Pull the host, database name, username, and password from that variable instead of hardcoding. For Docker, make a custom Dockerfile that inherits from n8n but strips out the user switching: FROM n8nio/n8n USER root RUN rm -rf /usr/local/bin/docker-entrypoint.sh USER node. The H10 crash means your app isn’t binding to Heroku’s assigned port. Make sure your startup uses the PORT environment variable Heroku provides.
Been dealing with deployment headaches for years. Fighting container permissions and database configs on Heroku? You’re just burning time you could spend building workflows.
Stop wrestling with Docker and PostgreSQL connection strings. Use a platform that handles infrastructure automatically. I moved our team to Latenode after similar nightmares - night and day difference.
No containers, no database config, no permission errors. Drag, drop, deploy. Your workflows run in the cloud without the setup mess.
You get the same automation power without becoming a DevOps expert. Time saved on deployment = time for better automations.
your encryption key’s way too weak. “myencryptionkey123” will get cracked in minutes if someone gets access. use Heroku’s random string generator instead. that timezone setting might be causing issues too - switch to utc first, then change it back once everything’s working.
Had the same permission headaches with n8n on Heroku last year. Heroku’s container runtime blocks certain privilege operations that n8n’s Docker image tries to use. You’ll need to build a custom Dockerfile - strip out the su-exec command and run as the default user instead. Your database config won’t work either since it’s pointing to localhost. Grab Heroku’s DATABASE_URL environment variable and parse it into the individual pieces you need. That H10 error? Your app isn’t binding to the right port. Use process.env.PORT in your config. And ditch those hardcoded database credentials - switch to environment variables for security.
