Hi!
I’ve deployed a Grafana instance (I know fly.io offers it, I just can’t add any other data sources and I prefer syncing my dashboards with code):
app = 'grafana'
primary_region = 'cdg'
[build]
dockerfile = 'Dockerfile'
[env]
ENV = 'dev'
# GF_SERVER_HTTP_ADDR = '0.0.0.0' # I've tried to uncomment but this has no effect
# GF_SERVER_HTTP_PORT = 3000 # Same here
GF_AUTH_ANONYMOUS_ENABLED = 'true'
GF_AUTH_ANONYMOUS_ORG_ROLE = 'Admin'
GF_AUTH_BASIC_ENABLED = 'false'
[http_service]
internal_port = 3000
force_https = true
auto_stop_machines = 'stop'
auto_start_machines = true
min_machines_running = 1
[[http_service.checks]]
interval = '30s'
timeout = '60s'
grace_period = '10s'
method = 'GET'
path = '/api/health'
[[vm]]
memory = '512mb'
cpu_kind = 'shared'
cpus = 1
Here’s the Dockerfile:
FROM grafana/grafana:11.5.2
# From https://grafana.com/docs/grafana/latest/administration/provisioning/#data-sources
COPY datasources.yaml /etc/grafana/provisioning/datasources/datasources.yaml
# I've tried with/without these lines below
USER root
ENTRYPOINT ["/run.sh"]
When I deploy it to fly.io, the app cannot be reachable but the health check if fine:
WARNING The app is not listening on the expected address and will not be reachable by fly-proxy.
You can fix this by configuring your app to listen on the following addresses:
- 0.0.0.0:3000
Found these processes inside the machine with open listening sockets:
PROCESS | ADDRESSES

Here’s a sample of the logs that seems to show that Grafana is indeed working:

2025-03-08T22:52:58.135 health[148e39e6b71408] cdg [info] Health check on port 3000 is now passing.
When I try to access the dashboard from the fly.io URL, it’s not accessible.
What I really don’t understand is that when I use that exact same Dockerfile to build the image locally, it works fine and I can access Grafana from localhost:3000. Any idea why this happens with this particular setup but not my other apps?
