DEPLOYING RPC TO AWS

[BMscis]

How do I run the ./reach rpc-server command from a remote docker container. I have tried to deploy it in AWS but I can't get reach to run.

[jeapostrophe]

That script runs a Docker container (most Reach commands do) so you need to have Docker installed and accessible to use it.

However, the code the container runs is trivial --- https://github.com/reach-sh/reach-lang/blob/master/js/rpc-server/index.mjs --- I would just use that directly if you were deploying the RPC server

[BMscis]

Yes I do.

[BMscis]

It occurs when it tries to readFileSync the tsl folder.

[BMscis]

*tls
Am I setting this correctly ?
export REACH_RPC_TLS_KEY="."

[BMscis]

Sorry that was the issue.

Is there a way to override the REACH_RPC_TLS_KEY for development ?

[BMscis]

I got it thanks.

Hey Jay, Im getting errors trying to use RPC-Client on the browser.

[BMscis]

Error "process.stdout.write" is undefined.
Error "net is not defined"

[BMscis]

If I try and use Postman for the requests and try
"https://localhost:3000/stdlib/getDefaultAccount"
I get a 500 server error with a message "unspecified fault"

[jeapostrophe]

Those errors sound like you need to webpack

[BMscis]

In what context though ? Because If I call "stdlib/health" it returns "true". Help me understand how webpack will resolve these issue ?
Thanks.

[jeapostrophe]

The process.stdout.write error sounds like because you're in a browser, you don't have the process global, which would get polyfilled by Webpack

Hey Jay,

I'm having trouble running rpcServer using docker.
I copied the rpc-server test in the reach-lang repo. It works with './reach rpc-server' call but when I try to run it with serveRpc, the client has trouble connecting.
Here's the link : https://github.com/BMscis/TicketingPlatform/tree/AuthUser/smartseat-ticketing/rpc

[jeapostrophe]

Yes, that message is from the client. You are running the server somewhere too, right?

[BMscis]

Right,

This is the response I get from the server, but the client hungs on

const accAdmin = await rpc('/stdlib/newTestAccount', bal);

And returns this :

No changes on the server log.

I think you should run the server with REACH_DEBUG=Y so you can see some more information

[BMscis]

Nice I've done that, here's the error,
