Nodejs app deployed with Docker starting without being called?

[tom-tom]

I have a NodeJs app deployed with Docker to Fly.io. Everything seems to be working fine.

But in logs, recently I started to notice that my app is being called during the night and it starts the system, where no one is using it.

I’ve setup the system to autostop the machine when not being used, as you can see in the toml file:

app = ‘test-app’
primary_region = ‘fra’

[build]

[http_service]
internal_port = 3000
force_https = true
auto_stop_machines = ‘stop’
auto_start_machines = true
min_machines_running = 0
processes = [‘app’]

[[vm]]
memory = ‘1gb’
cpus = 1
memory_mb = 1024

My only suspicion now is that web crawlers are calling the system and it wakes up with a firecracker.

Any ideas?

Yes it’s crawlers. Use cloud flare to block most of them or restrict access via IP
