The following commands are meant as examples only - the minimum viable settings are used to launch the service.
- This will launch 2 services in fly: a single node postgres instance and a stacks-blockchain (with API) using that DB.
- The name is randomized by
openssl rand -hex 6, producing a name likestacks-blockchain-9dbc4006e43e- using a common name doesn't seem to be supported (i.e. notstacks-blockchain) - The command
flyctl deploy --detachwill deploy the stacks blockchain service without waiting for health checks to return. Remove--detachfrom the command to wait on health checks. - Finally, to see the logs during the deploy - you can use the web UI, or run
flyctl logsto monitor the progress.

rm logs.txt- Blockchain sync time with the above VM settings will be a bit slower due to the shared single vcpu. For better performance -> use a higher resource VM
- Pricing for a 4GB instance for 1 month is about $30 with a managed DB
- When the command
flyctl postgres createis run, it adds an env varDATABASE_URLto the deployment. entrypoint.sh uses this env var to connect to postgres. - The cloned fly.toml will be overwritten to remove commented lines and replace the app name using the randomized string. fly.toml.sample is a copy of this file for reference.
